Low Slope Shingle Conversion to Flat Roof Membrane

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

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

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

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

Low Slope Roofing Challenges

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Low Slope Roof Membranes

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

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

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

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

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

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

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

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

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

Low Slope Residential Re-Roofing

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

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

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

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

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

Re-roofing Procedures

The photo above shows a Pine Shake to Shingle (IKO Cambridge Laminate Shingle) Re-Roof.

GRS re-roofs residential buildings and can make any modifications to the roofing system you feel would best suit your home. Our roofing services are available in Toronto, Calgary, Red Deer, Edmonton, Lloydminster, Saskatoon, Regina, Medicine Hat, Lethbridge, Canmore, Kelowna, Vancouver, Whistler and points between.

The roof openings (goosenecks, roof vents, skylights, valleys, plumbing flanges, etc) when you are re-roofing need to be tied in (flashed with metal and with roof membrane) properly. The roof openings and valleys of the roof (where roof lines intersect) are where all the problems start with re-roofing.

Re-roofing Specifications GRS uses to attach, flash, neck tie our roof openings is shown in the photo above.

When re-roofing a home, it is critical to neck tie (surround the roof penetration) with proper peel and stick or blue skin membrane to avoid ice, snow, water back up into your attic space.

In this instance, a roof vent (goose neck – notice it is a coloured roof vent) is shown. The deck of the roof has a premium Titanium Synthetic Roof Underlayment installed, then the IKO Cambridge Shingles – the goosneck also has a premium Karnak Caulking underneath, then the gooseneck is installed and nailed, then a blue skin or a premium Ice and Water or Peel and Stick membrane (such as Grace Membrane) to the horizontal (or back side) and vertical (or side) of the gooseneck (not shown in pic as not installed yet) and then the IKO Cambridge Shingles continue to be installed – taking care not to nail through the laminate shingle and through the ice and water peel and stick and into the back of the vent flange into the deck. Once a flashing is installed, you do not want to nail again through a shingle and into the flashing to the roof deck.

Re-roofing properly takes time, experience, quality material, and a sense of pride in the work done.

Our re-roofing experts are trained in the highest principles of roofing we know. It keeps our company from ever having to return to our re roof job sites for repair. It costs a little more to re roof properly, but the customer gets a roofing job done so well that it will last for many years. Of course, our roofing contracting business is built on references and referrals, so it is our life line – not to mention that our roofing installers get to work with pride of workmanship. A premium re-roofing installation specification and premium re-roofing materials also allow us to have a Lifetime Workmanship Guarantee on all re-roofing projects.

Shingle Roof: Coloured Flashings

General Roofing Systems Canada provides coloured flashing installation throughout Canada. 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.

Consider a Roof with Coloured Roof Flashings. It Shows Great!


Why not take that extra step and ask your shingle installation contractor to re-roof with coloured roof flashings?

Re-roofing with coloured roof flashings just finishes a shingle installation off right. This is especially important when taking off or doing a roof conversion from Cedar or Pine Shake and then re-roofing to an Asphalt Shingle. The profile of the cedar or pine shake roof is higher than the new shingles – along walls and such the old galvanized step and wall flashing will show poorly. The street appeal is greatly affected. Some roofing contractors will re-roof and install the shingles and leave the old galvanized wall flashing and a gap along the wall to roof connection for the home-owner to deal with, others will paint the wall flashing – but this creates a regular roof maintenance issue. GRS shingle installations include new coloured flashings to these areas to increase street appeal after the re-roofing installation is complete.

The photo in the upper right and the one below it is a recent Calgary Pine Shake to Asphalt Shingle re-roof installation that shows the coloured wall flashing at the roof to wall connection (click on the photo to enlarge).
Also included standard with the GRS re-roofing Specification is gable or rake edge coloured roof edge flashing. Gable edge flashing, especially a coloured gable edge flashing finishes the roof installation nicely and here again shows your home and completed roof installation with great street appeal.
Another area colour can be used in re-roofing is with the roof air vents. Coloured roof air vents are shown in the re-roof installation below.

Coloured flashing is also great to have installed at the roof valleys. If you are re-roofing with closed valleys, galvanized valley is fine (if you are putting metal in your valley underneath the shingles). Coloured metal flashing is standard with GRS Re-Roofing Installation Specifications and shows great from the street also.

The first photo above shows the installation of coloured valley flashing product and the second shows valley flashing installation completed and the wall to roof section still galvanized flashing (good photo for contrast between the two) and installation of the wall flashing still needs to be completed.
Our website includes a section that is actually the shingle re-roofing installers’ installation manual that details our re-roofing how-to and the specifications of re-roofing our installers are held to at this link:

Flat Roof Repair, Coatings, and Restoration

General Roofing Systems Canada provides flat roof coatings throughout Canada. Roof coatings are completed in the following cities: Calgary, Red Deer, Edmonton, Fort McMurray, Lloydminster, Saskatoon, Regina, Medicine Hat, Lethbridge, Canmore, Banff, Cranbrook, Kelowna, Vancouver, Whistler, Winnipeg, Toronto and points between. British Columbia. Alberta. Saskatchewan. Manitoba. Ontario.

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

 

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

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

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

 

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

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

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.

Roofing Calgary Alberta – Roof Repair Report [July 20, 2011]

Inspecting your roof before you buy your home is very important. The roof on your new home may be one of the most costly repairs you do after moving in. Some home inspectors just don’t have the experience to catch problems that can escalate the cost of roof repairs very quickly. Here’s a report from a roof repair from Calgary, Alberta today – our roofers didn’t even catch the problem prior to ripping the shingles off, how could the average home inspector?

Here’s the roof repair report that came in….

         “When we tore the roof of the area I had assessed prior, I discovered there were 3 layers of shingles beneath the one I had assessed which I did not see because they had used drip edge all the way around the roof edge so my small 10 bundle (low slope roof) tear off became a 40 bundle tear off with each layer of shingles becoming more difficult because of the time the shingles had been on the roof. This posed several problems not allowed for in the roof repair costing, first of all because of the fact that our roof repair garbage went from 10 bundles of shingles to 40 bundles of shingles (at about 70 pounds each), I now needed a bin to handle the added shingle tear garbage which I had planned to haul away in the pickup truck and not a shingle disposal bin. The man hours spent on removing the old roof shingles were already a little over total time allowed for the job so I phoned the customer and told him about the situation and that the cost to do the repair had doubled. He agreed under the circumstances I could not have foreseen the extra cost involved in this roof repair and approved us to go ahead and finish the roof repair project.”

Buyer beware – have an expert roofer inspect before you buy your new home!
