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.
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.

Note to reader: We have begun posting common roofing questions that we receive to our website, blogs, and on phone lines to assist those researching answers to their roofing problems. We edit out any personal information (denoted by ‘—‘) for obvious confidentiality reasons prior to posting. If you have a roofing question, email us at firstname.lastname@example.org and we will do our best to help you with your inquiry.
The inquiry came from a residential flat roof owner from Red Deer, Alberta that is considering preventative flat roof maintenance or flat roof re-roofing, as her flat roof is beginning to show signs of fatigue. Water is pooling or ponding and not vacating through the gutter system. The flat roof’s age is nearing 30 years, which is very near the end-of-life for a tar and gravel system. The flat roof is now very likely beginning to sag.
This particular inquiry is common. During the period that this residential roof was installed, flat systems were popular. Common residence types included revenue properties and duplexes, as well as high-end homes. The architects during that period specified many flat roof homes and many of those systems are now in the process of re-roofing or roof recovery retrofits.
Hello; I presently own a house in Red Deer where the house is presently 25 to 30 yrs old. It has a tar and gravel roof which has given me no problems whatsoever. However, I am looking at preventative measures. The neighbours in the crescent are all starting to re-roof their homes, now I am most likely considering the same.
I found this year that the water is not going into the eaves & it is becoming a concern, so I have decided to look at what could be causing this & the option of putting a roof over the existing one.
Do you re-roof in Red Deer, and if so, could you please come by and give me an estimate & advice? If you do not work in Red Deer, do you know of a reputable company who has experience in this type of roof?
I am the fellow on-call tonight (we run a 24 hour emergency roof repair service) so I thought I may as well respond while I have a few minutes – I’m your Regional Project Manager in Alberta.
To answer your questions:
We do work on roofs in Red Deer regularly. We do not have a physical office in Red Deer but it doesn’t make any difference as our trucks are going from Lethbridge to Calgary to Red Deer to Edmonton and Fort McMurray all the time. We regularly have roofing crews available in and/or through Red Deer.
That makes me wonder if the Calgary to Edmonton corridor will ever get a light rail high speed train system – not likely, but it sure would help me transport our roofers efficiently….
Sorry, yes – we do work in Red Deer and we do re-roof residential flat roofs on homes and we also do flat roof recovery systems as well.
My suspicion is that your tar and gravel flat roof, being that the roof is almost 30 years old, even though it isn’t giving you any trouble now, will be trouble soon. Of course, without a roof inspection and flat roof assessment performed on site, it is impossible to say, but your roofing system “symptoms” (it sounds like the flat roof system is sagging) are typically a precursor to roof system failure of some sort (leaks or even complete failure).
As the flat roof membrane begins to sag over the years water begins to pond and the process of degradation of the roofing layers – tar paper and bitumen occurs relatively quickly from there on. Also, the layers of roofing will typically begin to tear, become brittle from the sagging of the roof and exposure from the UV. Nonetheless, in saying that, there are ways to delay the re-roofing of your flat system or performing a flat roof recovery by exercising roof repair options.
So yes, we should take a look at your roof. Roofers are in “that season” now and roof assessment scheduling is tight. I am thinking I will have an opportunity some time —- as I am between Edmonton and Calgary 3 or 4 times between —– . So I will call you when it looks most feasible and give you ample notice – I am thinking —– will likely work for the inspection.
In the meantime, if you have any questions, feel free to call us anytime 877.497.3528 toll free or on my direct line(s).

Below you will find a field report from our 2011 archives for a residential shingle repair in Calgary, Alberta. Our report outlines the complications which can arise with respect to discontinued T-Lock shingles.
The challenge with repairing T-Lock shingles is that they are discontinued, so many homeowners are experiencing an unfortunately challenge. Many simply need a shingle repair, even if their system isn’t that old but had used T-Locks. Here is an example field report from the roof repair technicians repairing shingles this weekend from Calgary, AB.
Field Report, June 18 2011:
A and J attended; the roof is about five years old and in good condition (IKO interlock dual black). There was a puncture in the center of a valley. We spoke with the homeowner and told him the material used on his roof was discontinued, but he wanted us to find out if there was any chance of us getting it anywhere in Calgary. I phoned several places with no luck, but there was one location in the northeast quadrant of the city that informed me they had four to five pallets of interlock sitting in their yard. We took a drive up to the shop and found they had some earthtone cedar (IKO), with the rest being BP. Unfortunately, this did not match the style on our client’s roof.
Returning to the job site, we used putty knives to break the tar seal on the valley metal and carefully removed and reused the existing shingles. When we removed the old piece of valley metal, we found they had nailed it right in the center at the tops, allowing water to penetrate the vapour barrier. We were able to complete the repair without destroying any shingles.
General Roofing Systems Canada (GRS) Offers Asphalt Roof Shingle Replacement, Repair, and Maintenance in Calgary, Red Deer, Edmonton, Fort McMurray, Lloydminster, Saskatoon, Regina, Medicine Hat, Lethbridge, Canmore, Banff, Cranbrook, Kelowna, Vancouver, Whistler, Winnipeg, Toronto and points between.

Asphalt Shingle Re-Roof Material We Use and Review Below
IKO has a full choice range of shingle materials and has representation in Alberta, British Columbia, and Saskatchewan (IKO started in Calgary). IKO shingles are readily in stock at suppliers and retail stores like Rona. The quality is very consistent as well. The Cambridge, Royal Estate, Grandeur, Armourshake, and Crowne Slate are some of our roofer favourites.
From the IKO roofing website, “IKO believes the success and longevity of their company is attributed to three key ingredients: Top quality products, continuous innovation and state-of-the-art manufacturing facilities. A family-owned company now for three generations, IKO intends to be around for many more. IKO products are found on distinctive residential, commercial and engineering structures in more than 50 countries. IKO operates over 20 manufacturing plants globally.” [ Source: www.iko.com ]
GAF was founded in 1886, GAF is North America’s largest manufacturer for commercial and residential roofing.
From the GAF Roofing Website, “GAF attributes its success to be a unique philosophy of: Helping property owners & architects to make their best and safest roofing choices, helping supportive distributors and roofing contractors to build their businesses and avoid hassles.” [ Source: www.gaf.com ]
The roofers at GRS consistently rate GAF offerings (complete line) to be of excellent quality. GAF also provides specific solutions for various roofing requirements. They manufacture a premium asphalt roof shingle with a wide range of options for shingle style, texture, colour, and optional material that can be used for re-roofing your home (for example, GAF Tru Slate).
From the Certainteed Website, “CertainTeed is a subsidiary of Saint-Gobain, one of the top 100 industrial companies in the world. Saint-Gobain employs approximately 22,000 people in North America and more than 109,000 people in 64 countries world-wide.” [ Source: www.certainteed.com ]
Certainteed Roofing has a comprehensive offering of quality asphalt roof shingles. Some of them are known as top performers in their specific categories.
The reviews and ratings of asphalt roof shingles from the roofers at GRS reflect this statement as well. The Presidential, Landmark, and GrandManor Certainteed shingles compete extremely well in their respective categories. Our roofers consistently report the quality to be consistent. We have had excellent commercial and residential roofing success when re-roofing with Certainteed shingles like the Presidential, especially in areas where a shake-looking shingle is the only option (beyond real cedar shake) to comply with the architectural controls of a residential neighbourhood.
From the Malarkey Website, “Since 1956, Malarkey Roofing Products™ has operated as a family owned, professionally managed, privately held company, headquartered in Portland, Oregon. Malarkey believes in creating long-term value for customers and business partners. Striving for excellence propels Malarkey to new heights in polymerization and the development of long lasting products.” [ Source: malarkeyroofing.com ]
If you know anything about GRS and the position or ratings our shinglers take with respect to Malarkey, you will know that the reviews from our roofers are always positive.
Malarkey shingles are, in our estimation, one of the best alternatives to more traditional or popular asphalt roofing shingles like the BP Harmony, IKO Cambridge, etc. Not that these examples are poor shingles – they are very good asphalt shingles in their respectively categories. It also is not fair to compare a Malarkey Legacy with the Zone nailing strip and the modified rubber polymers in the shingle versus an asphalt-based shingle in a completely different category. However, what we do try, whenever possible, is to move our customers that would normally consider something along the lines of a BP Harmony or IKO Cambridge into a more premium SBS rubber-based IKO or Malarkey product (such as the Malarkey legacy shingle). Comparing a Malarkey Legacy versus an IKO Cambridge is not a reality; you have to compare a
Malarkey Legacy versus an IKO rubber shingle, not an asphalt one. The reason we try to move our customers up just one step in pricing is that the price difference is nominal for the premium quality you receive. Instead of a “good” asphalt shingle, you get a “great” one with SBS rubber modifiers.
Calgary, Alberta recently experienced two wind storms that blew shingle off approximately 25,000 – 50,000 rooftops in Calgary and Southern Alberta. We experienced not one blow off with the Malarkey Legacy shingles. Now that, in our opinion deserves a high rating!
Owens Corning Shingles
From the Owens Corning Website, “Owens Corning is a global residential and commercial building material provider. A Fortune® 500 Company for 57 consecutive years, Owens Corning is driving sustainability by delivering solutions, transforming markets and enhancing lives.” [ Source: www.owenscorning.com ]
Owens Corning asphalt shingles are now represented and readily available in British Columbia, Alberta, and Saskatchewan at roofing suppliers and retail stores such as Lowes. The quality of the Owens Corning asphalt shingle has always been good, alongside a comprehensive choice of colours, models, and textures.
Our experience with Owens Corning is more limited than with BP, IKO, Malarkey, GAF, and Certainteed but all indications are from the ratings and reviews from our shinglers is that they are a good quality asphalt shingle.
The BP asphalt shingle line-up is well represented in Western Canada and includes the Manoir, Everest, Mystique, Harmony, Mirage, Yukon, and Dakota. The Harmony shingle is the most popular of the BP shingles and it is available in a wide selection of colors. [ Source: www.bpcan.com ]
Cedar Roof Shake Looking Textured Shingles:
Designer asphalt shingles such as the Certainteed Landmark TL, Certainteed Presidential TL Ultimate, GAF Elk Grande Prestique, Certainteed Presidential Shake, GAF ELK Grand Sequioa, GAF ELK Grand Canyon, GAF ELK Country Mansion, GAF ELK Camelot, Certainteed Carriage House, Grand Manor, and the IKO Royal Estate and Armourshake shingles are examples of designer materials that achieve textured roof profiles.

There are a number of membranes available when considering flat roofing or low slope membranes for your home. The flat roofing section of our main website explains the various membranes available and this blog has a number of flat roof articles for your home roof that you can search.
Flat roof membranes fall into one of these categories:
Single-ply roof membranes such as TPO, PVC, or EPDM.
Two-ply membranes such as two-ply SBS modified torch-on (or cold applied).
Multiple-ply built up roof such as the traditional Tar & Gravel or the newer TOUGH ROOF, or multi-ply liquid rubber coated roof.
Spray-on roofing such as liquid rubber or spray foam.
If you have a low slope roof (4/12 slope or less), you will want to consider either low-slope membranes used on flat roof systems or a low slope shingle application. Most shingle manufacturers have considerations for low slope shingle application. Some, like Malarkey, also have warranties for such applications.
If you have a low slope residential roof and you are choosing shingles versus a low slope membrane, be sure to check with your local building codes, the shingle manufacturer toward warrant, and be sure your roofing contractors installs the roofing shingles in accordance to the specifications required.
Roofing Shingles, Cedar Shakes, Concrete Tile, Slate, Rubber, Metal, etc.
Roofing shingles are now available in hundreds of material types, styles, colours, textures, and are available in speciality types for moss, high wind, UV, hail impact, rubber, etc. Standard types of shingles are made by IKO, BP, Malarkey, Certainteed, GAF, and Owens Corning.
Speciality residential roof coverings such as cedar roofing, rubber tile, concrete tile, metal panels, slate, etc. typically require more research and due diligence than when choosing asphalt shingles. Homeowners have to be even more cautious with selecting the right roofing material and contractor. Failure to choose the right contractor could be a considerable error.
We also have a section on how to shingle a roof so that homeowners can learn about the right way to install shingles. Be sure to keep it handy if you ever have a contractor on-site so you can check if they are performing the installation correctly.
General Roofing Systems Canada (GRS) has extensive experience with roof snow removal, ice dam removal, and emergency roof response. Rooftop Snow Removal in the following cities: Edmonton, Red Deer, Calgary, Fort McMurray, Lloydminster, Saskatoon, Regina, Medicine Hat, Lethbridge, Canmore, Cranbrook, Kelowna, Vancouver, Whistler, and points between.
A Snowfall Warning was Issued at 4:21am for Edmonton, Red Deer, and other parts of Alberta.
The current question remains : Will the roofs be able to hold 15 – 20 cm if we actually receive that amount of snow on our roofs.
Environment Canada Snowfall Advisory that is presently released by the weather network
Issued at 4:21 AM MST Friday 24 February 2012
Snow is on the way.
A strong low pressure system off the British Columbia coast is forecast to track into Alberta today. Snow will begin in the Whitecourt region late this afternoon and will spread east southeastward into the Edmonton region by late evening. 10 to 15 centimetres of snow is expected by Saturday evening.
Snow removal services are a key part of our business. So when weather advisories like this occur, we are not disappointed as it enables our roofers to remain busy during the winter months.
HOWEVER, considering what happened last winter where roof collapses were almost daily due to business owners with commercial buildings in Edmonton, Red Deer, and other areas of central and northern Alberta being caught off guard and not able to get the snow off their roof-tops.
SNOW REMOVAL from a flat roof in a timely fashion is serious issue that GRS does not take lightly,
One of our main concerns is with some owner’s of the commercial buildings, especially those with large roof spans that have had major snow loads on their roofs last winter and have not taken the steps to structurally repair their roof systems. So when this amount of snow gets dumped on the roofs, Especially in one fall in such a short period of time, the snow will then get wetter and heavier causing more damage. Once the snow melts it is almost guaranteed that there will be a significant amount of damage and problems. We can almost expect a significant amount of calls coming from the Edmonton, Red Deer and area this weekend and next week.
HOW MUCH SNOW CAN A FLAT ROOF IN GOOD STRUCTURAL CONDITION HOLD WITHOUT IT COLLAPSING? The answer to that question is complicated. It depends on the roof span of the trusses, whether or not it is a flat roof or sloped roof etc. Last year there were roofs with less than 18″ that collapsed, but these were poorly designed and had very large roof spans. The problem is not just specifically snow, it is the rain on snow and the melting snow turning to ice or blocked roof drains when rains come. Considering the storms that Alberta had last winter with such drastic snow loads, there is a strong likelihood that many roof systems were weakened. Our advise is to remove snow from flat roofs in Alberta , especially if the snow loads are predicted to be quite large.
For more information on roof snow removal, ice dams, snow loads, attic ventilation and condensation, and various other things that occur to roofs when snow and ice cause havoc, you can search our blog. We have a number of articles written by our crews that have fought the snow loads on rooftops last season.
