A Step by Step Guide for Successful Execution of Contracting Roof Repair and Maintenance Services in Canada.

First, a Little Bit About Me.

I have been managing roof repair crews in Canada from Vancouver to Edmonton / Calgary to Saskatoon / Regina and Toronto / Mississauga for about ten years now. Repairs on every roof system type imaginable on projects the size of five football fields (industrial type manufacturing facilities) to small repairs on homes – products including flat roofs to shingles to roof coatings, metal roofs and many more.

This experience has given me unique insight that I hope will help you with engaging your roof repair challenges in such a way that brings success.

When your roof is leaking it is important to undertake repairs in such a way that successful remediation  is achieved in the most effective and efficient way. Re-do’s are not a good place to find yourself. Roof repairs are expensive, but more than cost, the inconvenience of business operation interruption or interior business or home damage can be considerable. And, in some instances a roof simply cannot leak (such as with molten copper facilities or steel manufacturing plants or buildings that house computer servers such as our clients that operate cloud computing operations).

The goal when starting the process of roof repair is to have successful completion in the most predictable, efficient and economically feasible manner.

Successful roof repair requires the following steps:

Determine the Type of Repair, Replacement or Maintenance Needed.

The reason you first want to determine the type of repair needed is so that you can effectively communicate with contractors you call, but more importantly so that you call the correct type of roofing contractor for the right type of roof repair. Also, if it is an emergency situation there are contractors like GRS that will attend 24 hours a day.

Do You Have a Residential, Commercial, Industrial or Institutional Roof?

This is important because you want to hire a company that has regular experience in the same working environment. When we are called to work in a mining operation for example or crews are required to operate within parameters that are appropriate to industrial operations.

Contractors that are equipped, trained and know how to function in required safety, have the appropriate insurance and more are important considerations.

In Canada we find our crews attending many industrial sites that require stringent safety procedures from nuclear and manufacturing in Ontario, to coal mines in British Columbia, the oil and gas industry in Alberta and Saskatchewan and much more.

Generally, What Type of Roof System do you Have? 

Is it a flat roof (low slope membrane), a steep pitch (such as shingles, tile or shake) or a low slope industrial roof? The reason this is important (beyond selecting a company suitable to the type of operating environment) is so that you hire a contractor that is an expert in the specific type of roofing you have. Flat (or low slope membrane) contractors are much more specialized in scope than say a shingle company (for example). The same applies for industrial low slope metal roof systems… some contractors only know how to replace a low slope metal roof and may not give you options for coating or recover options.

What Type of Roofing Product Needs Repair? 

Once you have identified contractors that work in your type of environment (residential, commercial, industrial, institutional) and you have determined that the contractor is in fact an expert for the general type of roofing (flat – low slope membrane, steep pitch shingles, tile or shake or low slope industrial metal) then it is important to know that the contractor is experienced and an expert at repairs for the specific type of product.

Not all flat roofing contractors (for example) are knowledgeable and experienced in all flat membrane material types. Flat roof membranes include variations of Tar and Gravel (Built up Roofing), SBS Modified (torch-on, hot tar mopped, or cold applied), EPDM (rubber roll roofing), TPO (Thermal Plastic), PVC (Poly Vinyl), Liquid Applied (such as hot rubberized asphalt, liquid rubber, or a white reflective coating) and more.

With steep roofs this can include asphalt shingles, shake, concrete or clay tile, synthetic tile, metal shingles, metal tile, composite tile, rubber tile, standing seam metal and so much more.

The point is that you need to identify a contractor that has specific experience in the specific type of installation. You do this by asking questions and discussing the contractors knowledge. Also, specific to the market in Canada we have noticed many spray foam contractors that may not have a background in roofing providing spray foam roofing systems.

The roofing trade is a red seal trade in Canada so you do want to consider due diligence as it applies to the contractor’s experience and knowledge of systems (more than just being able to apply spray foam and a coating).

What Options for Repair, Maintenance or Replacement are Available for the Specific Type of Product? 

In other words, you want to also know specific to your type of system and product what options are available. Let’s assume you have a tar and gravel roof that is leaking. You want to know first of all what options the contractor is proposing for repairs, maintenance and replacement (or a recover or coating). But more than that, if the contractor is recommending replacement you want to know more about the options for replacement (this can include removal of the complete system to the substrate, or perhaps only leaving the insulation after the top membrane is removed, or even simply removing only the gravel and putting another system on top of the old).

The point is, you want to know about all the viable options. Once you know all your options for repair, maintenance and replacement you can then focus on the actual “system” or “assembly” itself. The climate in Canada can be a significant deciding factor also, so it is important to understand how a membrane interacts with the climate (expansion and contraction, UV, insulating value and more).

What are Your Objectives? 

Your objectives will determine what the repairs, maintenance or replacement include. For example, if you have an old low slope metal roof (commercial or industrial) that is starting to leak, you may consider spot repairs with coating type material or you may consider a complete coating or replacement of the metal roof panels. But it wouldn’t make sense to consider spray foam to that roof if you are wanting to simply waterproof the roof. Spray foam roofing would make sense (perhaps) if your goal is for R value but not specifically for waterproofing a metal roof that is leaking. Why pay for R value when that isn’t what you need is my point.

Many of our Edmonton Roof Repair customers (specifically this area of Canada because of the regional marketing) make the mistake of getting a spray foam roof when they actually only needed waterproofing (accomplished with liquid rubber or some other roof coating with-out the cost of the spray foam). And for each roof system and type there are many considerations.

Tar and Gravel, Roof Repair, Mississauga

What are the Geographic Implications?

Different roof systems are better for different locations. Some membranes are better in hot environments and some are better in cold. Some roof assemblies make more sense in hot climates than cold also. Be sure your roofing contractor is knowledgeable in the different product offerings and the specific engineering and science behind each for your specific climate (achieving a net benefit to the building efficiency for example).

A simple example would be roof coatings – a reflective or white roof coating in a hotter (relative speaking in Canada) sunny climate such as Kelowna makes more sense than in a colder climate like Edmonton. A black roof coating vs. a white roof coating (reflective) in Edmonton, Calgary, Saskatoon, Regina, Winnipeg and even in parts of Ontario is more often a net benefit choice (simply because there are more cold days than warm so the objective becomes absorbing heat and not reflecting the UV).

The same applies to low slope / flat roof membranes – a black roof may make more sense than a white (reflective) roof in Edmonton, Calgary, Saskatoon, Regina or northern Ontario than in Kelowna, Vancouver or even in downtown Toronto. Our Toronto Roof Repair and Mississauga Roof Repair divisions constantly deal with the issue of white or reflective roof net benefit when inspecting and advising on roof replacement and repair. We are finding more and more stateside influence north of the border here in Canada with white roofs / reflective roofs and in cold climates they can cause significant issues with condensation and negative efficiency results.

Our main website has articles (go to grscanadainc.com and click on Flat Roofing) about the issue of condensation with white roofs in colder climates. Our Calgary Roof Repair division is seeing this at inspections all the time now.

Due Diligence. Once you have determined your roof contractor works on your type of building, on that type of roof, on your specific type of product and that he or she will offer the available options for repair, maintenance or replacement you then need to finalize your search with simple due diligence such as making sure they have enough liability insurance, they are registered with local safety as provided for by law and they are credible.

As mentioned above, in Canada roofing is a Red Seal trade so this should be an important consideration especially with commercial, industrial, flat roofing, metal roofs and coatings. Typically serious due diligence is only a concern at the residential level because the industrial and commercial roofing contractors are few (there are 200 residential roofing contractors for every significant commercial or industrial roofing contractor) and the residential contractors can simply start up quickly with-out a lot of investment etc. The commercial roofing contractors have significant upstart cost and compliance protocols that deter fly by night start-ups.

Conclusion:

It is critical to select the right type of roofing contractor for your roof repair job. This is accomplished by following the steps I have outlined above. General Roofing Systems Canada (GRS) performs roofing work on all types of buildings and on all types roofs and products. We also provide our customers with all available options for repair, maintenance, replacement (including recovers or coatings) as part of the roof inspection reporting and quotation phase.

Leaking Metal Roof Systems

A metal roof on a residential project may or may not be installed on a high slope. If installed on a high slope, it is less likely to leak However, many industrial and commercial roof systems are low slope. If a metal roof is installed on a low slope, chances are leaks will occur.

Why does Metal Roofing Leak?

Metal roofing expands and contracts with changing weather conditions, which causes the roof fastener holes to get larger over time. This is especially true in our unpredictable Western Canadian climate. Expansion and contraction of the metal causes the seams to expand and contract which can cause leaking as the seams  become less crimped or locked over time. Ice damming and snow loads can also cause metal roofing to leak. Ice damming can even back up at the eave of a metal roof,  especially if there is a gutter system that is frozen solid. Ice damming can move roof vents or various roof openings enough to cause a leak. Snow loads can weigh down metal roofing so much that seams become more exposed. Caulking of roof vents and roof openings become brittle and crack over time which can also cause leaks.

SG1S1511
Metal Roofing – Ice Damming at Eave

Metal roofing will also trap moisture on the underside, causing condensation that will eventually result in a roof leak.

Metal roofing is a watershed product,  not to be mistaken as a waterproofing product. Waterproofing is a completely different discipline in roofing. Metal systems are inherently designed to be secure yet will eventually leak.

SG1S1524
Metal Roofing – Roof Ice Damming Leaks

Metal roofing is one of the best roofing systems you can purchase in the world. It will outlast most other roofing surfaces. However, there are some exceptions that will last longer, such as: slate roofing, rubber roofing, concrete tiles, synthetic tiles. Nonetheless, a metal roof is undeniably one of the longest lasting roofing materials in the world.

What separates a roof that lasts fifty years and a roof that lasts twenty years is the quality of roofing material, the metal roofer’s installation specifications, and proper maintenance of the roof over the years.

Metal Roofing – Installation is Key

Quality metal roofing costs more than the less expensive versions.  A lower quality, less expensive metal roof may only last fifteen or twenty years. whereas a metal roof that is installed using a higher quality will last fifty years. In either instance, if the metal roof is installed poorly, a fifty year metal roof may only last a year.

A metal roof installation needs to be precise and needs to allow for the fact that it  is a watershed and not waterproofing material. By its nature, a metal roof  watersheds, therefore it is expected to eventually leak. Whether that leak will affect you is determined by a number of variables such as hidden fasteners that provide more protection than exposed fasteners, using locking panels, using a steep versus a low-slope system, and a premium roof underlay beneath the metal roofing material.

Replacement, Repair, or Restoration. What’s the Answer?

There are a number of ways to avoid the problem prior to needing to replace a metal roof. We won’t go in to those ways in this article, as this article is to assist those wanting to explore avenues of metal roof restoration, repair, or replacement.

General Roofing Systems will typically suggest a few answers to your metal roof leak problems:

Maintenance
Maintenance should be conducted on an annual basis. Caulking made for metal roofing is available and should be re-done every fall. Be sure gutters are kept clear during the winter. DO NOT let your gutters freeze up as this will cause problems with your metal roof. Also, snow loads are important; try your best to maintain a reasonable amount of snow on your roof. If possible, keep the snow off.

Repair
Repairs usually involve maintenance such as caulking, replacement of vents or some form of sheet metal fabrication for a detail on the metal roof. If the roof leak and subsequent repair isn’t focused to a specific issue, but is more of an intermittent leak issue, then you are likely best looking at a metal roof coating or a metal roof replacement.

Roof Coating – Liquid Rubber Technology

Coating
Coatings were once looked at as a short term solution.

New coating technology is extremely successful, long lasting, consistent, and has finally solved the roof expansion and contraction problem.

Liquid rubber polyether roof coating technologies are solvent free, maintain 900% elongation, UV resistant, bond to almost any construction or substrate, liquid cold applied, elastomeric, great for green roof applications, 100% solids and will not shrink, they are compliant with all known environmental requirements, resistant to thermal shock and slumping at high temperatures.

The first benefit of coating a metal roof vs. replacing your roof: Metal roof repair, or coatings, are considered maintenance and as a result are a tax deduction.

The second benefit of metal roof coating in today’s market is that the new liquid rubber coatings are highly effective, even more so than most new metal roof systems. The new liquid rubber coatings are highly advanced (developed as a result of nanotechnology) and the elongation values are in the order of 900% and are UV resistant. The roof coatings move with the expansion and contraction of the metal roof and keeping it waterproof.

The third benefit of the new metal roof coatings is that a roof coating will cost you about 1/3 to 1/2 the price that a new roof replacement would.

The final benefit to coof coatings worth mentioning is that the new liquid rubber polyether technology last several years.  We have a ten year warranty with an option to extend to twenty years in some instances (requiring a maintenance coat at 10 years typically).

Survey of the Commercial Roofing Process

General Roofing Systems Canada provides repairs to Commercial Roofs throughout Canada. Commercial Roof Repairs are completed in the following cities: Calgary, Red Deer, Edmonton, Fort McMurray, Lloydminster, Saskatoon, Regina, Medicine Hat, Lethbridge, Canmore, Banff, Cranbrook, Kelowna, Vancouver, Whistler, Winnipeg, Toronto and points between. British Columbia. Alberta. Saskatchewan. Manitoba. Ontario

Maintenance, Restoration, or Replacement?

When reviewing the process of commercial roofing, the first step is to decide what method of roofing is required. Of course, there will be decisions in regards to the metal used, yet this all depends on whether or not you have a flat roof. For example, you may be looking to repair your roof, perform annual maintenance, completely replace or restore your existing system.

Repairing Your Commercial Roof

Commercial roofing repairs are best done by a roofing contractor that complete repairs on a daily basis and who is aware of all the commonly accepted standards. GRS employees are highly trained to work with all varieties of commercial roofs; our crews undergo extensive training that help them to assess and repair any and all issues. Flat roof repairs are specific to the type of commercial roof such as; Tar and Gravel, Torch-on SBS, TPO, EPDM, PVC, Roof Coatings, or SPF – Spray Foam. It is important to have roofers that are aware of the type of commercial roof membrane that is being repaired.

Metal roof repairs on commercial buildings are also type-specific. These common types are are metal cladding roofs, standing seam metal roof systems, and coatings with a reflective coating or black rubber liquid coating.

The objective is to locate a commercial roofing contractor that has technicians with the knowledge of all commercial roof types.

Preventative Maintenance

Commercial roofing systems require regular maintenance. In most instances maintenance on a commercial roof (flat roof) should be completed a minimum of twice a year. It is recommended to have this completed once in the fall and once in the spring. GRS has specific commercial roofers that specialize in roof maintenance. Our roofers are aware what to look for and how to solve specific commercial roof problems. Our web site contains a step by step list for commercial flat roofing repair and maintenance:

Metal Roof Maintenance

Metal commercial roof systems also require regular maintenance. Maintenance should be performed on all the metal seams, metal roof fasteners, and roof openings. Sometimes this only requires a simple process of caulking (be sure to use high-end metal caulking). Yet with scenarios, when the metal roof is beginning to fail due to rust or expansion/contraction of the metal seams and holes for the fasteners, more extensive roof repair or roof restoration becomes a necessity. This is another area where it would be beneficial to have type-specific contractors completing the work.

Our roofing blog has numerous articles regarding metal roofing, metal roof repair, and metal roof restoration. Simply search your topic by category on the left hand side of the page.

Roof Restoration

Restoring Your metal or flat commercial Roof when regular commercial roof repair and maintenance doesn’t alleviate the problems you are experiencing with your metal or flat roof, more extensive restoration is required. One significant advantage of restoring your commercial roof rather than replacing it is the tax benefit. Roof restoration is considered maintenance and not typically considered a capital cost as it would with a complete roof replacement.

Metal roof systems are filled with challenges, especially in colder climates like Alberta and Saskatchewan. For example, in Edmonton, AB last winter, the snow loads were so immense with the ice damming on the metal roofs, as well as the heavy weight loads, that several metal commercial roofs were affected. Our metal restoration crews have been working nonstop since last winter to repair and restore metal roof systems on numerous commercial and industrial facilities. The advantage of having a metal roof on your commercial facility is the longevity of the material. Metal roofs are known to last several decades before requiring full replacemetns.

The inherent challenge with commercial metal roofing is that the metal expands and contracts. This is especially true in our unpredictable Western Canadian climate. Unfortunately, many leaks occur as a consequence.

When thinking about restoring a metal roof it simply comes down to two things. First is whether or not you would want white reflective metal roof restoration, or do you want a black roof?

In today’s market, there are several advancements to metal roof coatings. One primary example would be the liquid rubber polymers that were created for waterproofing commercial metal roof systems.

The challenge with reflective coatings for metal roofs is that coatings such as acrylic, which are highly reflective, also contain the disadvantage of cracking and peeling. The important items to be considered when choosing a restoration process or coating for your commercial roof is to be sure that the roofing contractor you hire is experienced and knowledgeable as to what is required. It is also important to inspect the coating material being used on your commercial roof. This is important due to market factors drastically changing over the past few years.

The same applies for flat roofing as it does for metal as we described above.
Coatings for commercial roof systems in this day and age have radically changed as restoring a flat roof today is not the same it was 3 years ago. At one time (and we still restore tar and gravel commercial flat roof this way), we would re-coat flat roofs with bitumen or tar from a hot kettle. Or in the case of a rubberized asphalt commercial flat roof, we would re-coat with hot rubberized asphalt.

Commercial roofing today has many more options. More recently many commercial property owners have been having roofing contractors spray foam their roof systems. With this process you skirt around the entire old method all together. Once the spray foam has been laid down you then add an acrylic reflective top coat to the SPF.

The process of spraying foam over an existing commercial roof is highly effective and cost efficient  – although this isn’t always the best method for an extended amount of time. There are coatings that are asphalt based that contain fiberglass that can be used to coat roof systems and emulsions. And then more recently elastomeric coatings have become available. This newer type sprays right over top of the existing system. Finally the most recent to come forward on the market is liquid rubber coating. Liquid rubber coating has been an excellent success for both roofers and owners alike.

Roof Overlays or Retrofits

An example of a roof overlay or retrofit is when your current commercial roof system has a tar and gravel roof. Instead of coating the roof and completely ripping out the roof and replacing it entirely, you can retrofit or recover it. There are many forms of flat roof recovery. One method is for our roofers to scrape or spud the gravel off. Our roofers will then install an insulation board and the roofing membrane right over top. For more information on retrofitting you can reference our blog and website.

Complete Roof Replacement

Complete roof replacements are a massive undertaking. In order to have this procedure completed correctly it is extremely important to choose the right contractor for your project. The contractor you choose must have roofers that are trained and have accurate knowledge of all roofing systems. In addition to this you will need to choose the right method of roof replacement or retrofit. Once you have done that, the next item to select will be the right membrane and search out a reasonable competitive price.

GRS has written extensive articles to assist commercial property owners with the process of completing roof replacements, some of which are on our blog and website. Here are some articles for your consideration when planning a commercial roof replacement:

Roofing, Roof Repair – Preventative Roof Maintenance Encouraged Before Winter Comes!

Fall has arrived and winter is just around the corner. This time of year is when people tend to be the most busy, with having just came back from vacation to children starting school and various other activities. With so much on the go for people, the last thing that you want to think about is the ROOF!

Yet the reality remains, this is also the busiest time for roofers, as facility managers and homeowners alike start to prepare the buildings for the harsh weather that winter brings. This is the best time to consider whether or not your roof has any current issues that need attending to.

snow and ice damming
Ice damming across a gutter system

The snow loads in Central Alberta and Northern Alberta were record setting. For many of the roof systems, if they did not fail or have issues last winter, it is almost certain they will have problems this winter.

We have  watched several commercial and industrial roofs completely fail in the Edmonton and Red Deer areas. The roofs literally buckled under the pressure from all the weight of the snow we received. Yet we believe this could have less severe had proper maintenance been taking place before the season hit.

This  winter has proven to be highly unusual. We experience such diversities in the climates all around western Canada. For example, in Vancouver our crews were busy with torrential rain, while in Saskatoon and Regina they were busy with snow falls, and in Calgary it was a constant cycle of  freeze and thaw. All this diverse weather  kept our roofing crews at complete capacity, often having to work many hours of overtime.

Some things to consider for your commercial, industrial, and residential roof maintenance prior to the next winter setting in;

Flat Roofing: Any flat roofing that took on heavy snow loads will most definitely require some attention. We highly recommend that owners heed the warnings from the previous season and at least asses the current quality of there roof, it would be best to have this assessment completed before the first snow fall. We have an annual roof repair and maintenance check list for flat roofing and the maintenance required to be completed listed on our website.


Metal Roofing: Metal roofing was hit the hardest last winter. The reason is that metal roof systems, especially commercial and industrial, had snow loads that compromised the metal roof panel seaming. In other words, the metal panels on the roof have been warped or pressed down so hard that the seams between the panels and the fasteners are compromised. The other issue we are seeing with industrial and commercial metal roofing this year is that many of the gutter systems are damaged.

The problem with metal roof systems on industrial buildings is that when the ice builds up in the gutter it will then back up and enter the building under the metal cladding. Fortunately, there are excellent solutions for metal roof issues yet most cases do require a full replacement.

Nowadays we can coat metal roofing with liquid rubbers. This is a elastomeric spray on roof coatings that will seal the metal roof seams, fasteners, and vents.

To learn more about how to solve metal roof leak problems search the topic on our blog at the top right corner. Simply type in your inquiry and our search engine will show results of the pages to help.

In addition to this, our main web site contains several pages on metal roofing, roof coatings, and roof repairs. You can find this information listed below with  the following links:

Residential Roofs: These systems did not have nearly as many structural  failures that occurred with Industrial and Commercial roofing last year. Although that is not saying that residential roofs, roof attic ventilation and condensation did not have their fair share of complications.  The reason being is that with the snow loads on roofs, the ice damming, condensation and ice backups in gutters, caused numerous problems.

As stated earlier, this winter season has been a treacherous one. Due to this fact, GRS would like to remind everyone to have an assessment completed on their roof for the next season BEFORE snow begins to fall.

New Generation of Roof Coatings

With every new product or technique there is always some skepticism to be had among both technicians and buyers alike. Yet with the new elastomeric rubber roof coatings, this has proven to be a positive experience among all who use/receive it. Our crews have been quite satisfied with the coatings that are placed down on the metal and flat roof systems.

Roof Coatings for Restoration, Repair, Maintenance

Liquid rubber elastomeric polymer roof coatings have proven to be quite efficient in the field. When metal or flat roof systems need repair, this new generation of roof coatings is something that should be considered for your roof repair or restoration process.

Roof Coating Warranty and Guarantee

Our liquid rubber systems come with a 10 year, no hassle warranty from the manufacturer. Yet GRS is able to extend this guarantee for an additional 10 years, giving owners a full 20 year warranty. In addition to this, our lifetime workmanship guarantee would also be honoured, therefore providing a full lifetime warranty for the duration you own the building.

Roof Coating – Why does a Metal or Flat Roof Coated in Rubber work so well?

Roof systems expand and contract and buildings move. The secret to the new generation of roof coatings is the coating elongation (900% or more) – they are suited to cold Canadian winters and summers. The new coatings stretch and move with the metal or flat roof systems. They are monolithic (there are no openings or seams) and they stretch. Metal roofs can be quite difficult to repair; finding the source of the leaks can prove to be quite a frustrating experience for roofers, business owners and homeowners alike.

Metal Roof Fastener Gasket (rubber around screw)
Metal Roof Fastener Gasket (rubber around screw)

Metal roof seams, fastener holes, fastener gasket, flashing, vents, etc. can all move, and expand/contract. Seams between panels become larger, fastener holes become larger over time, the rubber gaskets on the screws deteriorate over time from UV, and flashing gives way to ice dams and expansion and contraction over time. The new roof coating is able to solve this problem by providing a 100% expansion rate to all surfaces.

Cost of Roof Coatings, Roof Replacements, and Roof Repairs

The cost to temporarily repair your roof (whether it is a flat roof or metal roof) is typically around 10% of the value of the roof (average over lifetime of roof). The cost to replace your metal or flat roof is roughly between 8.00 and 20.00 per square foot. Essentially a roof coating will only cost you half of what a full replacement would. Both coating and roof replacements have the same length of warranties. And should you choose to go with a roof coating it is tax deductible as it is considered maintenance.

Roofing Calgary Alberta – Roof Repair Report [July 20, 2011]

Inspecting your roof before you buy your home is very important. The roof on your new home may be one of the most costly repairs you do after moving in. Some home inspectors just don’t have the experience to catch problems that can escalate the cost of roof repairs very quickly. Here’s a report from a roof repair from Calgary, Alberta today – our roofers didn’t even catch the problem prior to ripping the shingles off, how could the average home inspector?

Here’s the roof repair report that came in….

         “When we tore the roof of the area I had assessed prior, I discovered there were 3 layers of shingles beneath the one I had assessed which I did not see because they had used drip edge all the way around the roof edge so my small 10 bundle (low slope roof) tear off became a 40 bundle tear off with each layer of shingles becoming more difficult because of the time the shingles had been on the roof. This posed several problems not allowed for in the roof repair costing, first of all because of the fact that our roof repair garbage went from 10 bundles of shingles to 40 bundles of shingles (at about 70 pounds each), I now needed a bin to handle the added shingle tear garbage which I had planned to haul away in the pickup truck and not a shingle disposal bin. The man hours spent on removing the old roof shingles were already a little over total time allowed for the job so I phoned the customer and told him about the situation and that the cost to do the repair had doubled. He agreed under the circumstances I could not have foreseen the extra cost involved in this roof repair and approved us to go ahead and finish the roof repair project.”

Buyer beware – have an expert roofer inspect before you buy your new home!

Roof Replacement – To Replace or Repair the Roof?

The issue of whether or not to replace your roof or to just continue making repairs on the existing one poses to be a high debate this time of year. GRS thought it would be beneficial to others to post a roof report that came into our office that deals with this exact question.

To Replace or Repair the Roof: A Roofers Report

One of our Calgary Roofing Repair clients mentioned to me that he was having some issues with the skylights leaking on his cedar shake roof. The skylights were coming loose and causing damage every time we had a storm. He even had hail coming through it at one point!

He also mentioned some issues regarding the roofs chimney and how it had been leaking and that he was aware that the overall condition of the roof was in poor condition. Yet he still wondered if there was any way it could be fixed, focusing on the areas that were in the most urgent need of repair instead of replacing it all together.

The main house is a 12/12 roof with a 9Ft 5/12 section on all the eaves so the pitch change has flashing on it. Fortunately there are enough roof valleys and hips on the roof that we were able to make it to the top for a full roof inspection.

The first roof skylight we saw was the one that had been flapping around in the wind. The skylight was fastened from the inside and was about 25 Ft from the floor. The inside frame of the skylight had been ripped off from every fastening, all except for one screw. I was baffled as to how this skylight was not already blown away and laying in a field.

The back pan on this skylight along with three of the other four skylights was not running past the corner, causing it to leak. They had been tarred numerous times, yet the roof tar dried up causing it to leak again. This is the point in which the roof becomes a true nightmare.

The chimney had been decorated with stone work oer top of the flashing AND the existing roof where there is an area that is probably a short back pan on the top section. Lower down there is a diverter (Half saddle) which the top does not quite make it under the stone. It was either installed after the stone, or the stone was just not big enough to cover it.

I told the client in order for us to flash the chimney properly, the stones that were interfering would need to come off and put back on after the flashing was in place.

There are several areas where the cedar shake capping is missing, I would say there would be about two days’ work just to repair the skylights, chimney and replace the missing cedar shake capping. I told the client the cost required to fix all the damage would be a waste, as the money would be better spent going towards a new roof/ replacement where it would serve him better for many years to come.
