When completing low slope re-roofing systems it is important to take into consideration the correct election of material that adheres to the local building codes and material manufacturer’s specifications.
Below we have provided a guideline for low slope shingles, roof membranes of flat roofs, and metal roofing.

Low Slope Roofing Shingles

Serious thought is required when you are considering re-roofing a roof that has a slope that is less than a 4/12 pitch. Malarkey Roofing

For roofing with a 3/12 pitch regular shingles can usually be installed with 2 ply 15 lb roofing felt paper as underlay ( Be sure to check with your specific building code and the shingle manufacturer).

The General Roofing Systems Canada (GRS) specification for how to install roofing shingles is to never use felt paper. We prefer to use Ice & Water protection on eaves, valleys, and around chimney flashing.  In addition to Ice & Water,  we also use a  synthetic roof underlay such as titanium.

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

General Roofing Systems Canada (GRS) Edmonton Flat Roofers

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

  1. Single Ply Membrane: Single ply membranes come in the form of EPDM (rubber), TPO (Thermal Plastic), or PVC (Poly Vinyl). Single membranes are either fully adhered, mechanically fastened, or ballasted.
  2. Two Ply Membrane: The primary two ply membrane is the SBS Modified Bitumen that can be torched down or cold applied.

  3. Built up Roofing: Built up roofing is another way of describing multi-layer roofing. An example would be the traditional  roofs tops that are commonly referred to as tar and gravel roofs or flat-top tar roofs.

  4. New Built up Roofing: More recently, modern technologies have advanced the built up roof and newer built up flat roof systems. They now utilize environmentally friendly products and modifiers vs. the tar or bitumen that has been more commonly used in tar roof systems. The newer versions of built up roof systems are extremely tough and will outlast almost any other roof. They are VOC free, making them perfect sustainable offerings to low slope roof assemblies. Tough Roof is an example of the modern built up roof systems as is the GRS Liquid Rubber Built up Flat Roof (a four layer voc free engineered liquid rubber flat roof with 800% elasticity and contains environmentally friendly synthetic fabric between layers vs. traditional tar felt paper.

Low Slope Metal Roofing

Roof Coating, Industrial Roof, Metal Roof, Leduc II

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

With residential buildings, metal roofing is more typically found on steeper  roofs. GRS installs several of metal roofing systems to Mountain villages such as Whistler, Squamish, Canmore, Banff, Cranbrook, Fernie, etc.  More and more metal panel and metal shingle roof residential installations are growing,yet the greatest volume of metal work being completed is on industrial facilities.

An issue with this type of roofing is that there is no other form of roofing material that expands or contracts as much as the metal roofing does. The seams between the roof panels, the fasteners, roof openings at vents, chimneys, flashings, and skylights are consistently expanding and contracting . Due to this factor metal roofing systems are prone to leaks.
Another issue with the metal roofing systems is condensation.  Many roof leaks in homes or businesses are actually not leaky roofs, they in fact a pooling of water in the ceiling due to condensation.  It is important to deal with any condensation or leak issue before installing a new metal roof.
We are able to solve the problem of metal roof leaks by installing a premium roof membrane under the metal roof system. We use a premium caulking tape at the seams in addition to using hidden fasteners. Now one effective way to solve the potential of leaks or condensation issues is to torch a SBS modified membrane or spray liquid rubber before putting the metal roof on.

For a commercial roof and industrial metal roof that is leaking, typically we would coat the roof with liquid rubber. By doing this it helps to ensure that the roof  will be good for another 10 years or more. Trying to locate metal roof leaks and deal with them in an isolated way can be quite time consuming and unfortunately highly frustrating . For more information Click on the following link to go to our roof coating section of our website.

GRS Review of the Malarkey Legacy Shingle

The roofing crews at GRS are required to provide our office with complete documentation and comments regarding the installation of every roof. The documentation includes photos of the job site prior, during and at the completion of the shingles process. Amongst the photos there must be written reports of job progress, safety reports and various other documentation.

For assignments that have been specified as a Malarkey Legacy Shingle Installation, we find the comments from our crews to be consistent. Our roofers comment that with the Malarkey Legacy Shingle there is a general ease of installation, excellent quality of shingle line up and a lengthy life expectancy. The Malarkey Legacy Laminate shingle has become a favorite product for our crews and in every case they would recommend the Legacy shingle to homeowners.

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.

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 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.
