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:

Drone Video Footage of a Commercial Flat Roofing Project Installing Fully Adhered EPDM Membrane.

This particular flat roof is 4.5 football fields in size. It is a tar and gravel flat roof on an industrial / commercial building that has a failed roof system. We are installing a fully adhered 60 mil EPDM flat roof system on the building.

In colder areas of Canada an EPDM or SBS Modified Torch-On flat roof system are preferred. In warmer areas such as Vancouver, downtown Toronto, or in warm areas of the USA reflective systems such as TPO, PVC or reflective roof coatings should be considered.

The advantage of using EPDM (especially fully adhered) in colder areas like Alberta, Saskatchewan, Manitoba, some parts of BC and Ontario is that EPDM expands and contracts very well with the change in temperatures. 2 Ply SBS Modified Bitumen Torch-On flat roofing is stronger for foot traffic (if your roof is going to have a lot of foot traffic) but it is not near as flexible as EPDM.

We recommend fully adhered EPDM over mechanically fastened EPDM membranes and loose-laid EPDM membrane roof assemblies. Loose-laid EPDM is much cheaper because the install time is shorter than with fully adhered (and the glue is expensive with fully adhered) but the disadvantage a loose-laid EPDM ballast system is maintenance costs in future. If you have to move the rock ballast to locate leaks in the future then this can be very costly.

Low Slope Shingle Conversion to Flat Roof Membrane

Re-Roofing? Converting Low Slope Shingles to Flat Roof Membrane Roofing on Your Home or Considering Converting a Flat Roof to a Pitched Roof?

General Roofing Systems Canada Re-roofs Low Slope Roofs throughout Canada. Our roofing services are available in Toronto, Calgary, Red Deer, Edmonton, Lloydminster, Saskatoon, Regina, Medicine Hat, Lethbridge, Canmore, Kelowna, Vancouver, Whistler and points between.

Below you will find comments regarding various aspects of roofing conversions from our senior project manager.

One common challenge homeowners have when considering re-roofing a flat roof or a low slope roof on their home (we receive many inquiries about) are homes with a low slope pitch that currently have shingles on the roof and the homeowner is considering a conversion to a flat roof membrane when they re-roof instead of the shingles. Or, homeowners are considering converting a flat roof on their home to a pitched or sloped roof instead.

Low Slope Roofing Challenges

Low slope roofs on residential homes (in colder climates like most of Canada) can pose a significant challenge.

Vaulted Ceilings: Often these homes have vaulted or cathedral ceilings. The vault in the ceiling replaces the traditional steep pitch home attic space. The issue with this home design is that hot air from the inside of the house can more easily get to the underside of the roof sheathing. The problem with this is that the warm air causes snow on the roof to melt. Then when it cools down at night the melting snow turns in to ice and over time ice dams develop on the roof.

Attic / Roof Space Insulation: In these homes it is often the case that the insulation value is poor. Either as a result of moisture (roof leaks or condensation) or in many instances when the home was built very little insulation was placed in the roof cavity. Lack of insulation allows the hot air from in your home to get to the underside of the roof causing ice dams. It is critical to have proper insulation R values in your roof.

Ice Dams: The problem with ice dams is that they wreck roof membranes and roof shingles and cause leaks into your home. So basically what occurs is that the heat from in your home gets in to the roof assembly (sometimes the vapor barrier is non existent or faulty), gets past the vapor barrier, through a lack of insulation and heats the underside of the sheathing and ice dams build up. A steep slope roof has more opportunity to vent the hot air out of the attic because of the larger space available in the attic, the intake cold air at the soffits and the exhaust vents at the ridge (and the pitch is steep and taller which helps). Ice dams will work their way up the roof slope as freeze thaw continues. As the ice dams work their way up the slope the ice dams push up shingles and get under the shingles and melt as a result of the hot air from your home entering the roof cavity and this causes leaks in to the home. Low slope membranes are not as susceptible to this problem because the membrane systems are harder for ice to get under. If you stay with shingles vs. a low slope membrane you can also use Ice & Water membrane under shingles. A good drip edge at the eave edge may also help.

Ice & Water Membrane (for under shingles): Ice & Water membrane is a self-adhered membrane that should be installed in warm weather (commonly referred to as a peel and stick). With a low slope roof like a 3:12 you can get away with using Ice & Water on the whole roof and installing shingles over top. “Get away with” is a loose term I suppose – it isn’t guaranteed that just this step will solve your condensation or roof leak issues from ice damming. Your roof assembly and / or attic system is like the lung of your home. Just solving one of the many potential problems (such as installing Ice & Water) may or may not solve the problem. If your roof is a steeper pitch like 5:12 or more then I would only recommend Ice & Water at the eave area (about 44″), in valleys (under valley metal), and around penetrations etc. Our main website has a lot of information about these details at www.grscanadainc.com. Click on “steep slope roofing” and view the various article, links, etc.

Anyway, back to low slope roofing issues and Ice & Water membranes…

Ice & Water membrane is suggested because when the hot air from your home gets to the underside of the shingles and ice dams melt under your shingles the Ice & Water may keep the water from getting into your home. But it may not. At issue is that when one installs the shingles over the Ice & Water, the shingle nails are now penetrating the Ice & Water membrane. BE CAUTIOUS with claims by roofing salespeople that tell you this is not a problem because the Ice & Water or peel and stick will “self heal”. In other words, the claim is that when the nail penetrates the membrane that the membrane will seal around the nail – or self heal. Not all peel and stick membranes do this and you are relying on it actually occurring – there is no way to know if it did or did not seal around the nails because the shingles are now installed over top of the membrane.

Frost and Condensation: Frost will collect on the underside of your roof deck sheathing if hot air from your home gets to that area. When the frost melts it can appear as though you have a roof leak when water appears on the ceiling. Condensation can also make itself appear as a roof leak. As warm air enters the attic or roof assembly and has no where to go (your roof exhaust vents are not performing properly) then the condensation can turn in to leaks. This will typically manifest at walls, windows and doorways. Condensation can slowly ruin the complete structural components of any home. Leaks can be occurring over years inside walls and slowly destroying your home, not to mention the issues with mold and mildew.

Attic Ventilation: Attic ventilation is critical. Venting your attic or roof space (limited in vaulted or cathedral ceiling homes) is critical. If you do not get the warm air out of the attic or roof assembly in an efficient manner that heat will cause many problems (as above – ice dams, frost, and condensation that cause leaks).

Soffit: Also known as the cold air intake portion. The soffit area of your home is the breath in part of your roof assembly lung. The soffits are located under the roof overhang. Sometimes they are located at the wall or vertical part of the exterior of your home. This scenario (soffits at the wall) is common in “architecturally designed” homes that are looking for a certain street appeal. Anyway, intake soffits are critical. The cold air must enter the roof assembly and travel along the underside of the sheathing and in the process take the warm air from your home (that is entering the attic) out and be exhausted by way of a rooftop vent, whirlybird or ridge vent system.

Be sure the soffit intake air is not being hindered by attic insulation. Very often home owners that do not understand the principals of attic ventilation that do their own home renovations will put insulation over the intake vents of soffits. Be sure there is no insulation over the vent areas around the edges of your attic space.

Roof Vents: The exhaust portion of your attic or roof assembly. Roof exhaust ventilation is critical. Their are various guides for how much roof ventilation a home needs, but the problem with these guidelines is that every roof system and attic or roof assembly is different. The common guide is that for every 100 – 300 square feet of attic space you should have at least one square foot of rooftop ventilation (exhaust). We can help you design a roof vent exhaust plan to bring your probability of success as high as possible.

One quick side note about roof vents… I very often am witness to home-owners that get so frustrated trying to solve ice dam, ventilation, leaks, condensation and the like (especially with low slope roofs) that they end up listening to any snake oil or uneducated roofing salesman or roofer. And what occurs is that they end up with a combination of roof vents on their roof. DO NOT allow just anyone to start adding roof vents. A whirly bird installed near static vents on a roof will not work. It will cause the air to get sucked in to the roof attic and run immediately to the other vent and out – which does not help the cause to say the least.

Vapor Barrier: And finally we get to the vapor barrier. The problem with the vapor barrier is that finding gaps or holes in a vapor barrier can take time. Look for any penetrations through the vapor barrier. Inspect these areas closely. You may want to re-tape or caulk or seal in some way all penetration just to be sure they are air tight. If you have a low slope roof assembly this is near impossible because you can’t crawl in to the roof space typically.

Is there good news? I feel bad for homeowners that have these problems – they put their life savings into a home that in some cases becomes such an aggravation that much of their life can become consumed with the problem because in some instances the problem is literally destroying their home, the family peace, and their life long investment.

There is good news, but often it takes a lot of patience with the person or company that is helping you and it often takes significant investment.

My advice is to be sure you have an expert. An expert can take you through a logical process of elimination. In other words, the possible reasons for the problem are such… and the list is in order of priority… and at each step of remediation lets take a look at how the roof assembly now performs under different weather and seasons.

Our experts are often booked months in advance and I know that anyone else that I’ve met that is an expert at this is also booked well in advance normally. Don’t let that discourage you, book with an expert and take the time it takes to get it done right and save your investment money and peace of mind. And be very careful with quick fix salespeople in this category of work because you could be throwing good money after bad if you choose the wrong company or so-called expert.

Call or write us anytime… in this instance I would recommend you write us and email your situation to info@grscanadainc.com. The issue with just a phone call to our call center is that you will be put on a waiting list that could be for many months. But a letter can be tackled sometimes remotely by staff that have some extra time while in the office. Be sure to include when you purchased your home, the issues you are facing with your attic or roof, if the leaks or condensation issues are occurring only when it melts on a nice winter day or if issues are present when it is bitter cold in winter or even in summer. It really helps to get photos of your home from street view and rooftop view because we can often suggest solutions even before we attend for a rooftop and attic inspection.

Some considerations for low slope re-roof planning for your home:

Low Slope Roof Membranes

Today there are many more options than once available for home-owners considering flat roof or low slope roofing membranes for re-roofing. We can remove the shingles on your home and apply a number of different systems.

Homeowners call us with concerns over the cost of low slope or flat roof membranes (relative to shingles) and this becomes a serious consideration when planning for a residential re-roof project.

Low slope roofing has changed and many options are now available for re-roofing your home that are much less costly than the traditional low slope tar roofing or torch down roll roofing.

The other thing that home-owners often call about is taking a low slope or a flat roof and having it turned in to a pitched (or a high slope) roof.

Today, solutions are available for low slope residential roofs that don’t require the cost of traditional flat roofing or the expense to go from a flat roof to a pitched slope roof on a home.

Newer low slope roofing membranes are “single ply”. EPDM is a single ply low slope roofing membrane that has a 10 – 30 year membrane warranty (the membrane warranty is available for residential re-roofing as well as commercial re-roofing) and some flat roofers will tell you they expect the newer single ply roofing membranes to last 30 or 40 years. TPO is also a single ply low slope white roofing membrane. Also available is PVC – PVC is similar to TPO in that it is single ply and typically installed as white.

There are the older style systems being the torch down sbs modified bitumen roofing membrane (or roll roofing) and Tar and Gravel flat roofing (or BUR / built-up roofing).

All membrane systems listed above work on low slope re-roofing projects.

And finally, there are metal roof or steel roofing systems for low slope re-roofing and even shingles for slopes to about a 4/12 pitch. Some roofing contractors are applying low slope shingles to 3/12 but we consider it a tentative practice at 3:12.

Low Slope Residential Re-Roofing

EPDM Membrane: The residential low slope roof in the pictures of this post are of a residential low slope roof that we are re-roofing this week. The low slope shingles are being torn off and replaced or re-roofed and converted to an EPDM flat roof membrane. The EPDM roofing membrane system carries a 20 year manufacturer warranty.

Attic Insulation: Also in the re-roofing process, we are removing the sheathing from this home and an attic insulator is blowing in insulation. We are then re-sheeting the roof deck substrate and adding a low slope insulation board and finishing the roof assembly with EPDM low slope roofing.

Flashing: All the roof flashings are being replaced in the re-roofing process – the eave, gable, chimney etc will be replaced as will all roof penetrations. The two low slope skylights are being replaced.

Ventilation: The venting of this low slope re-roofing project will be redesigned and installed at the ridge or peak of the roof with a custom made ridge ventilation system that will have a curb framed in first and then the ridge vent along the ridge. This will allow for proper attic / roof space airflow and ventilation, it will keep snow from covering the ridge vent, as well the custom framed curb for the vent will keep snow from entering the roof system.

You can follow this residential re-roof project by checking back regularly on our roofing blog as we will post pictures showing the process of re-roofing from a low slope shingle roof to a low slope flat roofing membrane.

Flat Roof Repair, Coatings, and Restoration

General Roofing Systems Canada provides flat roof coatings throughout Canada. Roof coatings 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.

Technology has changed. Today’s flat roof coating technologies allow for GRS to offer highly effective flat roof coatings that perform extremely well, have relatively lengthy manufacturer warranties, possess tax deductible benefits that a new flat roof system can’t offer, and are economically more feasible than traditional roof maintenance systems (the new flat roof coatings have excellent life cycle costs not available in past).

 

Flat roof coatings available today are an excellent, predictable solution for waterproofing new or old flat roofs (low slope roofs). GRS has cool roof coatings (“reflective white coatings”) and we also supply and install black rubberized flat roof coatings (which are more commonly used in Canada). We have recently been installing a number of flat roof and metal roof coatings throughout Western Canada (early in the 2011 season) and we will be posting the process of those installations to our blog as soon as photos start coming in from the sites.

GRS flat roof coatings are an excellent solution for flat roof repair over most aged flat roofing materials except coat tar roofing (in which case a roof recovery membrane system is better suited). As a side note, we can offer an “out of the box” manufacturer warranty on the new flat roof coatings that is 10 years, and on flat roof recovery systems 20 years is available from the manufacturer.

Technology in both categories of flat roof remediation or restoration has certainly changed in recent years. GRS installs flat roof coatings over metal roofs (the photo above shows a metal roof coating in progress in Leduc, AB just south of Edmonton), BUR Tar and Gravel Roofing, Modified Bitumen SBS Torch Down Roofing, and Single Ply Roofing such as EPDM, PVC, TPO, etc.
Our flat roof restoration systems utilizing roof coatings allow our clients to avoid a complete re-roof tear-off; they complete the flat roof repair or restoration process faster; coatings lower flat roof maintenance and replacement life cycle costs; and roof coatings (or roof recovery systems) eliminate landfill costs.
Coatings are applied using a brush, roller, squeegee, and/or sprayers as required. The coatings cure quickly (set instantly and cure within 48 hours). With excellent advancements in roof coatings our client base has rapidly grown also, GRS has many satisfied commercial and industrial clients that can attest to the remarkable advances in product deliverables in this particular segment of the roofing maintenance industry. We strongly encourage anyone with a flat roof or a metal roof that is seeking replacement, repair, or maintenance to look in to this excellent solution.

 

In addition to the new roof coating products being an excellent solution and alternative to complete flat roof or metal roof replacement, many of our flat roof coatings are green, environmentally friendly roof coatings. A few points of note:

  • They carry a 10 year roof coating warranty.
  • UV resistant.
  • Have  tax deductible benefits as they are considered maintenance and not a new roof.
  • Coatings are cold-applied roof systems (no open flame is used on the roof).
  • Many of our roof coating systems do not contain any toxins or VOCs.
  • Highly elastomeric – in most cases are equal to or exceed 850% elongation with 95% recovery – that is a very elastomeric roof coating – they are able to adapt to surface movement and thermal changes like few flat roof solutions can.

Industrial Metal Roof Coating, Leduc AB 2011

Taken from the 2011 GRS archives.

General Roofing Systems Canada is a Canadian Based Roofing Contractor Serving Roof Coatings in Toronto, Calgary, Red Deer, Edmonton, Lloydminster, Saskatoon, Regina, Medicine Hat, Lethbridge, Canmore, Kelowna, Vancouver, Whistler, and Points Between.

Photos are starting to come in of an Industrial Metal Roof Coating project we have underway in Leduc, Alberta.

It wasn’t long ago that if someone wanted a Metal Roof Coating that would perform and last, we would have to shy away from engaging in a contract with a client. Quite frankly, the roof coating technology wasn’t what it is now. Modern day technology allows roofing contractors like us to literally coat a roof with liquid rubber and when the roof coating dries, it becomes a monolithic rubber membrane. It carries a 10 year warranty and is bullet proof.

Roof Coating, Industrial Roof, Metal Roof, Leduc

This industrial building in Leduc had us start the metal roof coating process late in 2010. Then, winter set in so our roof coating crew couldn’t continue until this spring. The rubber coating is perfect, even after having been coated and installed on this industrial metal roof right when winter set in. When we came back this spring it was perfectly intact, it adheres to the metal roof perfectly, it stretches and doesn’t crack, and it does not break down with UV. Our review of the new elastomeric rubber roof coatings is that they work, they are cost sensible, and are an excellent way to gain years on your metal roof repair and maintenance and allows metal roof owners to extend replacement for years if not decades into the future.

As this metal roof coating project continues in Leduc, we will publish photos and reviews, and next week we have other roof coatings occurring in Lloydminster, Alberta and other parts of Alberta on Industrial Metal Roofs that we will document for potential users of the products.

BASF and Carlisle SynTec Collaborate To Provide a Performance Roofing System

Wyandotte, MI June 21, 2011

BASF announced today a partnership with Carlisle SynTec to jointly market a high-performance roof. This roof would utilize Carlisle’s Sure-White™ EPDM FleeceBACK™ single-ply membrane with BASF’s polyurethane insulating technology.

This unique roofing systems helps to provide durability, sustainability and energy efficiency; all while delivering superior performance for wind uplift resistance and waterproofing. With this particular roofing system it also enables warranties to be issued for 10 to 30 years. The roofing components work together to create a seamless blanket of insulation that blocks out air and water while eliminating thermal bridging.

The system requires combining both Spray Polyurethane Foam (one of the best insulators in the commercial roofing market) with FleeceBACK EPDM and FAST® Adhesive. Both theFleeceBACK EPDM and FAST® Adhesive  are considered to be one of the most ultimate fully adhered commercial roofing systems available today.
