British Columbia. Alberta. Saskatchewan. Manitoba. Ontario.

Below you will find a simple account of a service call inquiry. Oftentimes, there are multiple contracting parties involved in a roof repair. This includes plumbers, the roofers themselves, other construction services in the area, and obviously the stakeholders themselves.

In this case, a simple misunderstanding concerning the purpose of water testing culminated in repeated requests for service calls outside of the ongoing work we had been performing for the client. Finally, our client’s property manager provided us with the implements to deal with the problem. As suspected, it was the plumbing – not the roofing system itself – which was causing major leaks.

We have included a comprehensive explanation from our national project manager as well as a follow-up correspondence by a third-party plumbing contractor concerning this matter.

Water Source Needed to Test Drainage System

As you know, for about a year and a half, GRS has been requesting a water source at the building to be able to test your drains. On each occasion, we have been told that a water source is being to be made available. As well, our crews have been told that it is likely the water source has been covered up in construction, but that we may be able to use a neighbour’s water source until a proper solution could be found. Up until today, no water source has been offered.

The Reasons Drains Need to be Tested

a. The source of the leaks were previously at the drain system. We requested the drain assembly (the connection to a new drain and U-Flow, and the connection to the drain) be redone with a plumber – we would provide the roofing services and the plumber would provide the connection services. This was not done at that time. My understanding is that the plumber only cleared the drain system. So, we requested a water source so that we could test the drains/plumbing ourselves to eliminate them as the main issue, or conclude that they are the suspected cause of your leaks.

b. The plumbing system and assemblies are old. It is common for drainage during times of heavy rain (which is when your building is having issues) to back up and leak at the drain bowl assembly connection to the drain pipes. As the water rises and then meets the bowl assembly, if there is not a U-Flow expander and/or proper drain bowl, the water will then get between the pipe and the connection to the bowl. What occurs is the water that is backing up will then get into the roof assembly and begin to run along various areas and manifest themselves through the ceiling. At the time of your roof replacement, there was no work order for the plumbing and drainage to be modernized, and normally this is not an issue. This this does become one, it is typically solved with a quick water test and simple remediation work (such as bowl replacement, U-Flow backup expander installations, and/or repairs to the drain pipes).

Discussion with the Site Manager

Water testing only works when it is not raining and is intended to isolate the drainage system from the roof membrane that we replaced. This is the reason for the need of an external/outside water source. We test the drainage system with a hose, which allows us to isolate the drainage system on its own. If that test does not show that it is the drainage system, then we go on to retest the membrane. We also test various other penetrations, such as rooftop units and/or vents, pipe boots, etc. Finally, we move onto testing various other components of the building envelope, such as the connection of the roof to the wall and the flashing areas.

Your site manager also asked that an emergency be done (such as pumping water off the roof), to which I replied that we could, if requested, dispatch an emergency crew for that, but we would have to charge extra because we have requested on numerous occasions for the water test to be done to the drainage system, and that has not been done. The site manager did not seem to want the emergency service under those terms.

I should also note that on the other occasions that we did respond in this fashion, that we did not charge for the emergency service. We did this despite finding that it was a drainage problem by the plumbers at that time. Furthermore, I will also note that on each occasion we did recoat the roof and did not charge for that either.

The only reason we are now saying that we have no choice but to charge a service fee is because we have requested number times to have water access. Part of our servicing parameters included that should the water test not to be done, that we would charge a fee for the emergency service.

You also asked us about why water was pooling on the roof. I explained to the site manager that at the time of the roof replacement, an engineered sloped insulation package and rebuild of the building exterior (parapet wall construction, sheet metal, siding, etc.). We were only approved to go ahead with the roof membrane replacement only. He asked why that was so, and I said that it is an option and that not all (in fact, less than 50%) of the buildings we service have a sloped insulation package installed. I directed him to all the neighbouring buildings as examples of those that do not have such sloped systems.

Discussion with the Property Manager

I explained to the general property manager that we needed to test the various components of plumbing, membrane, units, vents, plumbing boots, and possibly the building envelope at the roof to wall connections. Finally, we have been promised an external water source to isolate the issue based on our tests.

Plumbing Contractor’s Follow-up with the Property Manager

August 21, 2015:

I was sent out to have a look at water leaking in the building. I found that the roof was full of water and it is what was pouring into the suites. The one drain was working, but very slowly. I called in the drain cleaners and went through it with them.

The snake was getting caught up on something, so I had them use the camera and we found there is something stuck in the piping. We traced it to the piping in the ceiling of a first floor room. We will need to return when the water is all gone and open the ceiling, remove the piping, and then get the cause of the blocking out. As it stands, the system is draining as much as it can with whatever is causing the blockage.

Also, the building has some piping up to the roof drains. These are not ran well and are back-graded for parts of the system. I have left it disconnected for the drain that has the problem.

A metal roof restoration is a less expensive alternative than having a roof replacement completed.

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 roof 7 (2)
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.

Metal Roof Maintenance

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.

100_0086
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).

Re-Roofing Your Home | Be Sure to Inspect Your Attic First!

General Roofing Systems Canada provides re-roofing services throughout Canada. Toronto, Calgary, Red Deer, Edmonton, Fort McMurray, Lloydminster, Saskatoon, Regina, Medicine Hat, Lethbridge, Canmore, Banff, Cranbrook, Kelowna, Vancouver, Whistler and points between.

Inspect your attic space before you start your residential re-roofing project.

Replace wood deck sheathing that is rotted or water damaged, analyze attic air exchange, and install attic air vents to be sure your attic is ventilating properly. Check for heat loss at the vapour barrier, be sure your insulation is doing the job, and replace plumbing boots, roof flashing, etc. as required while you are at it.

When replacing your residential sloped roof, it is critical to inspect your attic space first.

If you re-roof your home without inspecting the attic for roof rot, water damage, vapour barrier issues, heat loss to the attic, and proper air intake/exhaust, you are risking have to re-roof again in half the time or worse.

If this occurs, what was the real cost of your new roofing shingles?

Proper ventilation in your attic, building envelope heat loss, proper insulating, and other components of professional shingle re-roofing standards and procedures all play important factors in the process of a shingle roof replacement, and it greatly affects the length of time your new shingles will last.

The best roof shingles are shingles that are on the best roof system.

You can have the best shingles in the world and they will prematurely fail if your roofing system is deficient.

If you install a new shingle roof, and you do not check the attic space, you are SG1S1505really re-roofing shingles (or any other roofing material) with a lot of risk to your newly shingled system. Not to mention, most people decide to re-roof their home due to the fact that something is not right with their roof to begin with. We heard statements such as:

  • “The roof is leaking.”
  • “The roof is ice damming, and now snow or water backup is causing roof leaks.”
  • “The roof valleys are leaking.”
  • “Our shingles are just no good and they need to be replaced.”

The point is, there are many reasons roof shingles do not last as long as they should.

For example, if you have a vapour barrier issue (warm air from the inside of your home is entering the attic space) and the warm air entering your attic space is then causing ice damming on your roof, the ice damming then causes leaks (the ice or snow on the roof melts and freezes and melts and backs up under the shingles and then leaks into the attic, all because the underside of the roof sheathing is too warm due to heat loss into the attic). Moisture then causes roof rot to the sheathing which isn’t healthy. The ice backup on the roof damages the shingles and roof underlay, the moisture destroys your insulation, and the water leaking into your home can do all sorts of damage.

Before you re-roof your home and pay the cost for new shingles, you want to know if heat loss into your attic is occurring or your roof sheathing is rotten. If you do not do this before the new shingles are installed, you risk investing in new roofing and the roof rot not being uncovered and replaced, and the warm air coming in to your attic that now causes roof ice damming the following year and perhaps the roofers didn’t install ice and water properly or at all or metal to the roof valleys under the shingles or a host of other possibilities and now you have a brand new shingled roof that cost you an arm and a leg that is leaking with roof rot on the roof sheathing and you need another new roof! You see the possible problems? (Talk about a run on sentence!).

Ice and Water Membrane to Back and Sides of Roof Openings, Wall, StepFrom the same example, let’s say you do not do an assessment of the air ventilation and now you have a new shingle roof, AND your attic air intake is plugged at the soffits by insulation. On top of that, your roof vent exhaust isn’t working properly because you only have four duro-flo air vents at the ridge for a 2100 sq. ft. home/attic space. You’ve had leaking in your home due to condensation in the past and your roof system can’t breathe and your old shingles deteriorated prematurely with your last roof. By now you must be thinking “My roof or shingles only lasted 12 years, and the limited shingle warranty was for 30 years! What the heck?).

Well, news is that your new roof shingles will only last 12 years. Your new limited lifetime warranty on your shingles won’t cover the costs because your roof ventilation ratio is not right, your intake air is compromised because there is insulation covering the intake vents at the soffits, and the exhaust attic ridge vents can’t work properly either…. not to mention that your house is 80 years old and the vapour barrier is compromised and is letting warm air into your attic space, etc. etc. etc. Replacing shingles after having new shingles put on only 10 years earlier is not where you want to be (especially when the wife finds out that it wasn’t the roof shingles fault!). Anyway, sorry I am off track…

The lesson here is… your new shingles will last decades and decades and decades if the roof system and attic space is proper for the new roof shingles to perform properly (and you look like the wise leader of the home to boot!)

I think we all get the point here…

As of 2011, our new policies mandate that we cannot re-roof a home with shingles unless a thorough attic inspection is done prior.

The GRS Standard Re-Roofing Specifications and Pricing now allows for this service in the price we quote you for new shingles. It also allows for a venting analysis, new roof vents, plumbing boots, etc. in the cost of your new roof shingles. Movement of insulation away from the soffit areas is also in the cost of your new shingles, as well as replacement of deck sheathing up to 100 sq. ft. As long as you don’t have a major roof or attic space remediation issue requiring the services of a restoration expert, for the most part, the price you receive from GRS for re-roofing your shingles is the same price to also bring your attic space up to par so the system performs as it should.

Some examples of standard GRS shingle replacement specifications are:

Roof sheathing needs to be replaced if it is rotting (which is also a health risk) or has excessive water damage from ice damming back up – this is a Standard Specification in the GRS Shingle Re Roofing Cost and our shingle re roofing prices include up 100sq ft of roof sheathing replacement. Air ventilation calculations are required and an analyis of your attic ventilation is completed free of chaege, air vents are included in the new price of your shingles, inspection of the insulation and inspection of your vapour barrier is also included in the cost of your new shingles. Insulation replacement and vapour barrier replacement is not included in the price of your new shingles but the inspection is included and is complimentary.

Metal Roof Repair or Replacement?

General Roofing Systems Canada provides metal roof replacements throughout Canada. Metal roof replacements 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.

Metal roofing is a vague word in the roofing world as it can be used to refer to a variety of systems. There are metal roof shingles, steel shingles, metal slate profile shingles, metal shake-looking shingles, metal panels, standing seam metal roofing, corrugated metal roofing, metal roof tile that are coated with granules… you get the point. The options in metal roofing are almost endless now.

One consistency that remains among the variety available to you is this: metal roofing can last longer than any other kind of roof’ however, a metal roof that is installed incorrectly will only last as long or be as durable as the workmanship of the install. If the underlay, or the venting of the roof system/attic is not correct, then problems such as leaking and ice damming will occur. With the weather that we have been receiving this year, one might see their metal roof may leak in multiple locations as time goes on. It is a frustrating experience living under a metal roof that has not been installed correctly.

To Repair or Replace?

Yesterday we had an inquiry come into our call center that is very common for us to receive. We felt this particular case would be a good addition to our blog in an attempt to help clients in their future endeavours while completing roof projects. 

On Monday, Jul 25, 2011 at 1:27 PM, the client wrote:

Hello,
We have an interlocking style metal roof that was installed by company 5 years ago by the previous owners.  The roof leaks in the winter as a result of ice damming in the valleys, and in the spring shingles annually become loose (and have blown off) on the edge of one of the valleys from the ice sliding off.  I am tired of dealing with the company (long story) and we are wondering if there is any way to repair rather than replace what they did.  We have a log house with cathedral ceilings so I suspect we need to try to improve the airflow under the existing metal shingles. I don’t know what it looks like between our open ceiling and the metal shingles above (regarding insulation and air flow). There is no venting other than vented soffits (as far as I can tell). Is there any way to seal the metal shingles so water doesn’t flow back up under them?  I don’t know if any waterproof barrier was used in the valleys and I don’t think the roof was installed very well in some parts. After talking with the previous owners a couple years ago, I know they weren’t satisfied with the installation of the metal roof, but they ended up having to relocate before going through a winter.
A couple of other things to note;  a few of the metal shingles were damaged when we were trying to remove the ice from the roof this past winter, and when we had heavy rain, the water comes off the roof before making it to the eaves.
I attached a couple of pictures of the roof so you can see the design.
Based on these pictures, if we had to replace our roof, what would be our best options (type of shingles, venting, etc.), and how could we reduce the potential for ice damming and leaking? How much would you estimate replacing a 1400+ sq. ft. home’s roof with different types of materials?  Is there a guarantee on the ice damming/leaking after the roof has been replaced? Is there anything else I need to know or can I provide you with more information?
Our Response:

Good morning,

I’m the Project Manager for GRS. I travel across Alberta solving roofing problems. However, it’s peak season and I may not be able to get out and take a look as quickly as I would like. That being said, what I am going to do is send this email to our two senior sloped technicians/foremen at GRS as well as our scheduling manager.
Our scheduling manager will keep you informed on our work in progress, and either myself, or one of our foremen, will come out to meet you. In the meantime, I’ll offer for them to chime in their input based on your email and photos (great email by the way – it helps us a lot).
Here’s is my opinion in regards to your questions….
1. From the perspective of someone that sees literally thousands of roof problems a year, my first advice would be to not listen to just any idea of repair from just anyone. Metal roofing is a specialty. A very common thing we see is homeowners trying different “metal roof” contractors in haste and it tends to end with negative results. Both of our foremen are very senior technicians that would not have you running around a circle. If we don’t get to you as soon as you like, and you hire someone else, please make sure to validate the experience of the technician. It would be more beneficial to be thorough with your next selection as any experienced person can rattle off hundreds of client situations and references. In our case, we lay out our experiences on our blog to provide our clients and future clients with quick and easy access to references.
2. I think the end result of your situation is going to be a new roof replacement. Now I understand this is not what you want to hear, and you may find it convenient in a consumer’s mind for me to say.  However, I will explain the reasoning behind my conclusion. We don’t need to sell you a roof, we’re always over-booked so the motive isn’t there. Secondly, we see these installation issues all the time; our blog is full of how to do it right – and when it isn’t done right, it is almost impossible to correct. However, in saying that, both myself and my technicians may assess your building and be able to find a less expensive solution.
3. Based upon your descriptions, I am thinking that it is an inherent design/installation issue. Metal expands and contracts and is a water shed system – not waterproofing. The roof underlay installation is flawed at the valleys. At minimum, I would think the valley areas would have to be ripped out (probably 5 feet on either side) and proper underlay installation executed and metal tiles put back in or new metal tiles placed.
4. Even after doing all that, it is a low slope roof, and you may have intermittent issues either way. That is how I end up at the roof replacement as an end result.
5. With respect to ventilation, that likely could be assessed over the phone with one of our foremen.
So I may not have helped or may have, but the bottom line is that typically the best thing to do is to start over with a roof replacement. Get the underlay, the ventilation and the water shedding product right. Once this has been completed, I believe your issues will be resolved.
Thanks
 Client Response:
Thank you for replying so quickly.  I suspected that we would have to replace the roof.  This isn’t a rush job, but if we could get it done before snowfall, that would be great. If we have to over-winter this roof again, is there anything we could do in the valleys temporarily? Like heat cables or….? The interior log walls got water staining on them last year and I am concerned with the condition of the wood below the metal tiles in the valleys.  In the case with a low sloped roof, would asphalt shingles be a better alternative to metal?
Please put me on the waiting list for an assessment.
Our Response:
 

Good morning,

No problem. The day’s just getting going here so I had the time.
With respect to roof replacement before winter, yes this is very possible. However, I would like either one of my foremen or myself to look at your property prior. I would like to make an attempt at finding a less expensive solution.
If for some reason you were thinking of not approving the work before winter, heat cables aren’t a good solution. Short of using a high quality tarp on your whole roof, it won’t help.
Metal roof systems are fine as long as the underlay is correct. Shingles won’t leak as easily, but don’t last as long. Any roofing product will work as long as the roof underlay and venting is correct.
We will get out to your property as soon as possible to meet you and take a look.
Thanks

Location: Calgary, Alberta
Roof Type: Shingles, Sloped, Residential
Problem: Chimney Leaking from Roof Top

 Roof Repair – Technician Report “How to Repair Roof Leak from Chimney”

A client of GRS was experiencing a leak in there roof and requested a full repair. Upon observing the roof and the chimney, our technician determined that the cause of the leak was isolated to the chimney area.

Our technicians replaced the chimney back pan that another company had serviced over a year ago. Despite having been serviced not long ago, the client was still experiencing leaks.

For this particular roof we were able to complete the following repairs: remove shingles from the area around the chimney, remove the siding from the chimney, remove the old metal roof back-pan at the back of the chimney, install a premium roof underlay (ice & water shield) on both sides if the chimney onto the top step flash and on the front – running the ice and water roof underlay up the chimney approx 8″. Installed the new chimney back pan, replaced shingles and siding.

Our phone lines are backed up at times – we have never experienced not being able to attend to the volume of calls before, and out waiting list can be frustrating for some (please accept our sincere apologies for this), so we have put a list together as a guide to help you during the hiring procedure for an available contractor.

Some things to consider when hiring someone to remove the snow or ice from your roof

  1. Ask for a copy of their insurance. Be sure you see it first hand. We carry a $5,000,000 liability for a reason. If the person you hire falls off your roof and is injured or is killed and they do not have the proper insurance, you will be held responsible. Most homeowners do not know how important this is. VERY IMPORTANT.
  2. Workers’ Compensation Board. Ask for a copy of their WCB. Ask for a WCB clearance that is recent, as this shows they are up to date their their premiums and active.
  3. City business licence. Self-explanatory… be sure that you see it first hand.
  4. Experience. Easy to check. Look at their website and client base or ask them for some of their clients you can contact. Call references if they do not have a detailed website that shows experience.

You must get someone on your roof with experience

We only put experienced roofers on our work-sites to remove snow and ice or do repairs. Of course, we also staff helpers, but a certified or very experienced roofer is important. Here’s why: only a roofer knows that if you step in a valley that it shingles, and subsequently when thaw comes the system will leak terribly. A roofer knows you cannot step on the shingle cap. An inexperienced worker on your roof will cause damage – guaranteed. These damages will not show up until thawing comes around, and then your roof will leak. Cost wise, a leak is much worse than snow removal.

When calling us for roof snow removal, ice dams, and roof repairs…

Our phone lines are busy – we really, really apologize. Many of the calls we are getting are commercial and industrial roof collapses or major roof leaks into homes and businesses. It can be tough to keep up.

However, we can help you in expediting the process. Here is how it works:

  1. We are a 24/7 roofing company. Although you can call us, email works better.
  2. We have moved our roof workers into the Edmonton area from all over Western Canada, so we have a lot of staff assisting in the effort. It may not appear organized on the surface, but there are people available.
  3. When you call (877.497.3528) or email (info@grscanadainc.com) our offices, we will take your information and put you on the list of people that need their roof to be serviced.
  4. Our office takes all the inquiries and consolidates the orders, then organizes logistics. We arrange scheduling according to address, severity, etc.
  5. If you put your name on the list and you find someone else to service you prior to our return call, then simply notify us and we will take you off the list. Be sure your contractor has insurance.
  6. You can elect to be put on our 24/7 standby service. As availability opens up, we will call you back when your site can be fit in-between other calls.
  7. The best way to get on the service list is by using email or by using our online form on our website. This automatically puts you in to the scheduling system. Click to Request Roof Quotation.
  8. Keep in mind that even if we estimate our availability as five days, it may be the case that another client cancels or reschedules.
  9. While you are waiting for a callback, you can read through our various articles at the main GRS roofing website as well as our main roofing blog and local blogs. After you have read pertinent field reports and have done a homeowner roof assessment, give us a call and perhaps we will be able to solve some of the leak issues right over the phone.

If you are calling about an industrial or commercial roof snow load or roof repair concern and think you may have a dangerous situation developing, call our 877 line and be sure to send an email along with it as well. All emails are instantly seen by our roofing managers in the field.

All things considered, what might be an emergency in a residential context, for instance, could be as simple as plugged roof vents. Nevertheless, our lines are open and waiting to help answer any questions you have.
