What Not to Do When Shingling Your Roof

General Roofing Systems Canada provides installs shingles throughout Canada. Shingle installations are completed in the following cities: Toronto, Calgary, Red Deer, Edmonton, Lloydminster, Saskatoon, Regina, Medicine Hat, Lethbridge, Canmore, Kelowna, Vancouver, Whistler and points between.

Before you shingle the roof on your home, please starting by reading our article below on “How to Shingle a Roof”  the right way and search our blog on tips for re-roofing your home.

WARNING: This may hurt egos and feelings, please be patient, we’re just trying to help (and keep the mood light).

We see countless homeowners every year have to re- shingle their home only years or months after having shingled their home themselves.

When homeowners get the idea to shingle their own roof, on one hand we stand back with admiration (because it takes hard work!) and on the other hand we get concerned because the shingle packaging (which gives specifications to the experienced shingle installer), the Home Depot or Lowes clerk that sold you the shingles, and the relevant YouTube videos don’t always tell you everything you need to know to successfully shingle your roof. The important words here…. “successfully shingle your roof”.

Because we see the story of “how to shingle a roof properly” unfold in front of our eyes every year, and because the errors cost homeowners real money, stress, embarrassment, etc, we’ve decided to write a bit on What Not to Do When You Decide to Shingle Your Own Roof. This will follow up on articles about how to Re Roof Shingles Properly (simply search the topic in the search box in the right hand top part of our blog and a number of articles will come up on re roofing the shingles on your home). Our main website also has articles at the following link in the right hand column of the page.

https://www.grscanadainc.com/Pitched_Roofing.html

Here’s what we see this time of year: it’s summer time and the kids are out of school and dad says “it’s cheaper for me to shingle my roof than it is to hire a roofing company to do it”.

TRUE … If the roof on the home you shingled yourself lasts. FALSE, if it lasts less than 10 years.

Here’s suggestion Number 1. Ask a reputable roof shingle company to come and consult you on site. It will cost you a nominal amount of money to have an expert consult you on shingle choice, roof specifications, and installation of the shingles correctly. Heck, a lot of shingle experts will even come by when you are working on your home and correct what’s a little “off” and you will be so glad you took our advice and did this one small inexpensive step.

DO NOT re roof your home with shingles without an expert shingler on your roof or consulting you.

What we see every year is folks that want to save money on the re-roof of their home – which we totally get. Instead of asking for help with HOW TO SHINGLE YOUR ROOF PROPERLY, they go out, buy their shingles at the local hardware store, and then shingle their home without prior guidance.

Here’s what happens, and it happens a lot. We could tell you story after story after story where homeowners re-roofed their own home and this occurred…

  1. The shingles, the shingle underlay, the shingle flashings, etc….. are improperly installed and the shingle manufacturers warranty is now void.
  2. Because the shingles are engineered to be installed a certain way to shed the water and the homeowner didn’t install the shingles the correct way, THE ROOF IS NOW LEAKING.

  3. The homeowner then attempts to repair the shingles to save face, hoping to save hundreds/thousands of dollars that could be used otherwise

  4. It rains again, and the SHINGLES ARE LEAKING AGAIN. You see what’s coming?

  5. You fix the shingles again. Only this time, things are getting tense because you are now reminded of the $2,000 repair to the interior of your home (and you are not even going to believe that there is more damage in the attic space itself).

  6. It rains again, and you are praying like mad the shingles won’t leak … and here we go, THE SHINGLES ARE LEAKING AGAIN.

  7. I won’t scare you so much that you now click out of your internet browser… so you can conjure up what occurs at stage 7 in the “how to shingle your roof with success drama”.

  8. You finally give in……. and you call the ROOFING EXPERTS TO FIX YOUR SHINGLES while YOUR ROOF LEAKS AGAIN.

  9. The roofer voices their opinion on the previous installer’s ineptitude, (but you don’t let it hurt your feelings … much).

  10. After having incurred the cost of the shingles that you didn’t install properly, you now have to buy the shingles all over again.

The lesson…. have a professional roofer install your shingles OR hire a professional to at least consult you on how to shingle a roof properly.

I will guarantee that you will be happy you did.

So if you want to shingle your own roof – all the power to you, just call and get a hand with doing it right.

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 info@grscanadainc.com 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.

Client Inquiry:

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?

Our Response:

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).

Thanks for your inquiry and we will see you soon!

Low Slope Roofing: Metal, Shingles

Low Slope Flat Roof & Metal Roof
Low Slope Flat Roof & Metal Roof

General Roofing Systems Canada installed low slope roofing systems throughout Canada. Roof installation; 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.

When re-roofing low slope roofing systems it is important to be sure you are using the right material for the right roof slope, local building code, and roof material manufacturer specification.

Below we provide a guideline for low slope shingles, roof membranes of flat roofs, and metal roofing.

Low Slope Roofing Shingles

Serious consideration is required when you are considering re-roofing a sloped system that is less than a 4/12 pitch.

For roofing with a 3/12 pitch, regular shingles can usually be installed with a two-ply 15 lb. roofing felt paper as underlay.

The GRS specification for installing roofing shingles is to never use felt paper. Instead, we use Ice & Water protector on eaves, valleys, around chimney flashing, etc. and use synthetic roof underlay such as titanium. In this instance (with a 3/12 roof), I would consider seriously using only an Ice & Water membrane versus the two-ply roofing felt. This is especially important around chimney and skylight flashing, and any roof vents, valleys, and openings.

A roof that has a 2/12 – 3/12 slope is more tentative and the risk increases. Some shingle manufacturers such as IKO with the Cambridge shingle will put a 12-year warranty on low slope roofs. Malarkey shingles will honour a 30-year warranty.Malarkey Roofing

A roof that is 2/12 or less in slope should have a “flat roof” or traditional “low slope membrane” installed. We like to see any roof that is less than a 4/12 slope get a low slope membrane that is fully adhered, mechanically fastened, or ballasted.

Low Slope Roof Membranes (Flat Roofing)

Low slope membranes for flat roofing come in a few categories:

  1. Single-ply membranes in the form of EPDM (rubber), TPO (thermal plastic), or PVC (polyvinyl chloride). They are either fully adhered, mechanically fastened, or ballasted.
  2. Two-ply membrane, the primary choice being SBS modified bitumen that can be torched down or cold applied.
  3. Built-up roofing (BUR). Another way of describing multilayer roofing. An examples would be the traditional tar and gravel roofs, or flat-top tar roofs.
  4. New BUR. More recently, modern technologies have advanced the built-up roof so that they utilize environmentally friendly products and modifiers versus the tar or bitumen commonly used in tar roof systems. These newer versions are extremely tough, will outlast almost any other roof (in our opinion), and are VOC-free, making them sustainable offerings to low slope roof assemblies. The GRS liquid rubber built-up flat roof is an example of a modern system with 800% elasticity and environmentally-friendly synthetic fabric between layers, as opposed to employing the use of traditional tar felt paper.
  5. Spray Foam Roofing.
Low Slope Roof

Low Slope Metal Roofing

Low slope metal roofing (steel, cladding, standing seam) has been used primarily in industrial and commercial settings for decades.

With residential roofing, metal is more typically found on steeper residential roofs. We install a lot of metal systems at mountains villages like Squanism, Canmore, Banff, Cranbrook, Fernie, etc. We also do a lot of residential metal roof shingle installations in cities like Vancouver, Edmonton, and Calgary. Residential metal panel and shingle installations are growing in popularity, but the greatest volume of metal work is on industrial facilities by far.

Low Slope Metal Roof
Low Slope Metal Roof

At issue with metal roofing is that no other form of roofing material expands or contracts as much as metal does. The seams between roof panels, the fasteners, roof openings at vents, chimneys, flashings, and skylights are expanding and contracting all the time. Ultimately, metal roofing leaks due to this expansion and contraction.

Also, condensation with metal or steel roof systems can be an extremely frustrating situation. Many roof leaks with homes or businesses are actually not leaky roofs. Instead, it is water coming through the ceiling as a result of condensation.

Dealing with the potential leak or condensation issues with metal roofing in advance of installing a new system is key.

We solve the problem of metal roof leaks with installing a premium roof membrane under the metal roof system, using a premium caulking tape at the seams, and installing hidden fasteners. If you really want to solve the potential of leaks or condensation in advance, torch an SBS modified membrane or spray liquid rubber in advance of putting the metal roof on.

For commercial roofing and industrial roofing that already has a metal roof on that is leaking, typically we will coat the roof with liquid rubber and it will be good for another 10 years or more. Trying to locate metal roof leaks and deal with them in an isolated way is not usually a good investment of time. Click here to visit the roof coating section of our website.

Asphalt Shingle Re-Roof Material We Use and Review Below

IKO Shingles:

GRS repairs and replaces IKO roof shingles on a daily basis.

IKO Roofing Shingles
IKO ROOFING SHINGLES

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 Shingles:

GAF was founded in 1886, GAF is North America’s largest manufacturer for commercial and residential roofing.

GAF Tru Slate - Slate Roof

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).

Certainteed Shingles:

CERTAINTEED SHINGLES
CERTAINTEED SHINGLES

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.

Malarkey Shingles

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 asphalMalarkey Roofingt 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 Shingle
Malarkey Legacy Shingle

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

OWENS CORNING SHINGLES

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.

Owens Corning Colonial Slate

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.

BP Shingles:

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 ]

Low Slope Residential Roofing

Low Slope Membrane

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.

The typical covering for residential roofing is to have roof shingles, cedar roofing, some form of roofing tile, or metal roofing installed.

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.

Our blog has a number of articles about selection of specialty residential roofing and our website can assist with a checklist for choosing roofing contractors, roofing contractor accreditationroofing contractor workmanship guarantees, and it also contains overviews of residential roofing materials available.

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.

Roof Snow Removal, Ice and Snow Loads on Roofs

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

snow
General Roofing Roof Snow Removal Crew on Industrial Roof

Snowfall Warning

Issued at 4:21 AM MST Friday 24 February 2012

Summary

Snow is on the way.

Details

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.
