Roof Shingles Damaged by Windstorm: Winter Storm Warning Announced!

CALGARY – Tuesday November 29, 2011



General Roofing Systems Canada is repairing wind damaged roofs through-out central and southern Alberta due to the storm that blew roofs of homes and businesses last Sunday.

Several homes and businesses were affected by this storm , as a result our roofers have been providing emergency repair services to the following cities and the municipalities; Calgary, Airdrie, Cochrane, Lethbridge, Taber, Okotoks, Nanton, High River, Bragg Creek, Red Deer, Sundre, Carstairs, Drumheller, Strathmore, Chestermere .

Below are some photos taken by GRS emergency roof repair crews, of the shingles that have been blown off roofs. Many homes have had the shingles blown off right down to the plywood leaving no roof underlay left at all, just bare plywood.

Now that the wind has blown off not only the shingles, but also the underlay  our concern is that many of these roofs are being left completely exposed to the elements.

To make matters worse, as of  tonight at 9:27 PM Environment Canada has issued a storm warning for Calgary and Southern Alberta, with lots of snow expected! Things are going to get much worse on these roofs. 

There was enough significant damage caused to shingles that when the roofs start leaking from snow cover, the insurance claims in Calgary and Southern Alberta will go through the roof.

Here’s the Winter Storm Warning for Calgary and Southern Alberta Storm Warning

Calgary, Alberta

Winter Storm Warning

Issued at 9:27 PM MST Tuesday 29 November 2011


Snowfall amounts of 10 cm or more and blowing snow expected by Wednesday morning. This is a warning that dangerous winter weather conditions are imminent or occurring in these regions. Monitor weather conditions…Listen for updated statements.


An intense low pressure system off the northern tip of Vancouver Island is expected to move across the Rockies after midnight. As the system redevelops in Southern Alberta many forecast regions will experience a brief risk of freezing rain. The precipitation will then quickly transition to snow as cooler air moves in with the low. Snowfall accumulations of 10 cm or more should be expected by noon Wednesday for the City of Calgary, Kananaskis, Okotoks, Airdrie, Cardston, Lethbridge, and the Cypress Hills forecast regions. As the low moves eastwards strong northerly winds will develop behind it generating widespread blowing snow in the City of Calgary, Airdrie Drumheller, Brooks, Okotoks, Lethbridge, Cardston, Medicine Hat and Cypress Hills regions.

The wind blew the shingles and the roof underlay right off this roof. The underlay was only a #15 pound felt, this is why GRS only installs to a specification that won’t allow this to occur in a wind storm. The roof underlay is critical for keeping the roof from leaking.

This photo shows why the shingles blew off and why it is important to have a trustworthy roofers that will install underlay when they are supposed to, to the roof. If you look close, in some areas of this roof, under the shingles was no underlay installed at all. And, the nails are not installed properly in the shingles. The shingles blew off this Calgary roof because most of the nails are not place in the double laminate of the shingle and the two end roofing nails are not within 1 inch of the ends and the shingles are not storm nailed.

Extreme Wind Damage in Southern Alberta

CALGARY – November 29, 2011, 1:29 AM, Field Report:

GRS emergency repair crews have been repairing wind damaged roofs in Calgary and Southern Alberta all day and in to the evening. The damaged roofing in Calgary is a result of a wind storm that blew through earlier today. To make matters worse, Mother Nature has decided to grant us with even more troubles as it rained a few hours ago and is now beginning to snow. This will result in numerous leaks for Calgary roofs.

In Downtown Calgary today, the winds were recorded to have reached 145 km/h.

With our roofing repair crew working non-stop, we thought a quick report from the field would be appropriate while we take a quick break from the back log of roof repairs.

To reach our Emergency Roofing in Calgary and Southern Alberta call +1.877.497.3528 or locally our emergency roofers can be reached at 1.403.873.7663.

High Winds Cause Havoc to Roofs and buildings

Emergency repair crews

Downtown Calgary and surrounding areas have had buildings glass shatter causing Calgary Firefighters to scramble in attempt to clear all debris to prevent any injuries happening to citizens.

The amount of damage that this wind storm has caused is impressive. Normally with wind storms the damage is isolated to one city and area, yet this particular storm is spreading its wrath to all of Southern Alberta. The damage that is causing is not isolated to only knocking down trees and power line. We have been receiving various types of reports of damage being caused.

In Airdrie we received reports of a church losing its siding, while in Fort Macleod, a gas station had its entire roof blown away. In Beiseker, grain silos and commercial roofs were being blown completely away.

The same variety of damage has been reported all the way to Lethbridge and surrounding areas. Grass fires have even began to occur due to the intense wind.

At the top of the Calgary Bow tower, the winds were recorded to be at a dangerous 140 km per hour, whereas in other parts of Southern Alberta is has been reported the wind gust are even stronger in areas such as Nanton and its surrounding municipalities.

The 911 call centers have been over loaded with calls relating to roof damage. As a result of this Calgary has engaged the Municipal Emergency Plan.

Steps for Fixing Damaged Roofs When high winds blow shingles, tile, and metal or damage your skylights:

1. Emergency Roof Repair Services. Call a roofing company and get on their emergency service list. In our case, we are asking emergency call ins to continue calling other Calgary Roofing Companies to be sure the soonest available emergency crews can come and assess the damage. At GRS, we are keeping a running list of home-owners and businesses that require emergency roof repair service and we are dealing with the repairs on a first call – first serve basis.

2. In extreme high winds, such as those in Calgary today, for your safety we advise you to stay away from windows and stay indoors. Due to the winds blowing off various forms of sidings, tiles, shingles skylights etc., it is unsafe to be outside with this vast amount of debris being blown around.

3. Roof Insurance: Be sure the roofing company selected to attend the repair of your shingles, commercial roof, metal flashing, or skylight keeps excellent record. You will need accurate photos before and after the roofing repairs. Make sure to ask the emergency roofers to provide you with copies of photos for your roof insurance company. Also, ask the roofing company to quote you for a complete replacement and have photos documenting all damage to your roof or skylights. After the immediate roof repairs are done, you can then address your possible roof insurance claim properly. Commercial properties are more apt to engage their Commercial Insurance Adjusters right at step one.

4. Choosing a Roofing Company: Be sure the roofing company you choose to do the roof repair work has a City Business License, have provincially incorporated roofers, Better Business Bureau registered and able to provide written receipts. Ensure that they take photos of work done for your roof insurance companies records. A quick check of complaints registered at the Better Business Bureau on line can help determine if the company is reliable. If it is a commercial or industrial roof repair, be sure the emergency roofers are qualified specific to the commercial roof system type.

5. After the emergency roof repairs are done, you have will have photos of the roof damage, and will now be dealing with your roof insurance company. Remember that insurance companies will refer you or want you to deal with specific roofers. However, in many instances, you have a choice as to which roofing company actually does the work. High Wind Shingles (Wind Resistant Shingles) Shingle manufacturers do make shingles rated for high winds.

Applying Shingles in the Winter? Roofing Contractor Guarantees? Attic Condensation? Roof Venting? 
The re-roofing post below is a continuation of an article written earlier this year that represents our discussions with a homeowner’s frustration due to an improperly installed re-roof.
On Wednesday, Nov 23, 2011 at 9:36 AM, our client wrote:
I have a bunch of questions/concerns:
We were wondering what happens when we book a week and then that week turns out to be snowy or really cold, especially if that happens part way through the job?  Under what conditions do you not work? Do we have to be there when the work is being done? Our roof already has snow on it and because it is metal; it is very slippery. When our metal roof was being installed, the previous owners said that the roof was exposed during a rainstorm and it caused water staining on our walls.  I doubt we will get rain but will snow cause issues if you are part way through the job and it snows?  Do you do it in sections so that the roof isn’t fully exposed? Would a roof that is installed in the winter be any different in performance or workmanship than a roof installed in warmer temperatures? Will the high shingle cap be adequate for ventilation? And if it isn’t, what happens if we have problems? We are just concerned that we spend all of this money and we end up with a roof that still causes us problems.
For payment: I see at the bottom of the quote that you take VISA. What other methods of payment do you take?  I don’t think my credit card limit goes that high so could you combine credit card and personal cheque? Does payment happen after the job is completed or do you require a down payment?
We have company from Nov 29th to Dec 13th (not sure when they are leaving).  Does the 13th work, or will you be available early into the new year?
Our Response:
Dear —,
You have some very good questions in regards to the re-roofing process. There are many homeowners that rush into a re-roofing project without all the correct information. This unfortunately causes them to realize later on that something was missed, misrepresented, or simply should have been discussed.
With respect to how weather affects the shingle process with your home, more specifically in your instance , how winter roofing affects the shingle application. We have an off-site section of our main website that provides information regarding how to shingle a roof. This also details some examples of completing this type of project during the winter months.
Now with winter weather, especially the bitter cold or periods with large amounts of snow, this can push our crew schedules back across the entire company. Although with that being said, the winter can actually be a better time to complete a re-roof project as we don’t have to worry about the rain.
However, winter shingle application can only be completed with if the temperatures stay above  -18 C or better.  Applying shingles at temperatures below the shingle manufacturer’s recommendations can void your warranty.  Most manufacturers mandate installations above -18 C.
The perfect temperature for re-roofing shingles or the actual process of the shingle application is -10 to +10 C. Shingling is best done when it is not too cold as shingle nail blow-through occurs with brittle shingles (leading to shingle blow-offs when high winds come). Nail guns don’t fire properly in the extreme cold, and roof nails may not sit flush as the ice on the shingles may hinder the nails from sinking into the shingle and roof deck correctly. This is only one example of the various problems that could arise.
In continuation to the temperature, it is also preferred for it to be not too hot. If the temperature is too hot, this also causes damage to the shingles due to them cracking underneath our roofers feet. So the idea is to pick a week that has moderate temperature. We prefer late fall, winter, and early spring, yet with moderate temperatures preferably between -10 and +10 c. The snow on the roof is not an issue at all with re-roofing (unless it’s really extreme) as we close up what we work on everyday with the use of proper roof tarps, and if required, roof connections, etc. Sections of the roof are done one-by-one.
With regards to your roof venting and/or antic ventilation, proper roof or attic ventilation is more specifically assessed when the old roof material is removed (air intake at the roof soffit, air exhaust at the roof vents and/or ridge venting). If the roof’s ridge vent allowance at the peak is not appropriate, our roofers will cut back a half or full inch or whatever is required from the roof sheathing that meets at the peak.
The truth is that we guarantee our roofing workmanship for the lifetime you own your property.  We have a proprietary shingle application method that enables us to do this. However, we do see some instances where condensation issues in the attic or roof system continue post re-roof. No roofer, building envelope consultant, or engineer that I have met or roofed with know for sure what will happen, and no roofer can honestly guarantee that roof or attic condensation will not be a problem after the re-roofing is complete.
When our crews have completed the re-roofing there will be no leaks. The workmanship, roof application methods, and our exclusive specifications are guaranteed to be the best you can get in the roofing industry. The roof ventilation will be installed directly to code, and the roof shingles will be of a very high quality (search our blog for Malarkey, for example).
One consideration to keep in mind is the fact that roof or attic condensation can be caused by a plethora of building envelope scenarios. There are several roofers that leave potential customers feeling at false ease prior to starting a re-roof. They do this in an attempt to mitigate issues that may arise with condensation in the future.
Now in regards to payment for your re-roof, we do honour all credit cards and cheques upon completion. We do not take a deposit prior to the start of a re-roofing project . When the work is complete and you are completely satisfied, we then request payment in full.
A final note to scheduling your re-roof, we have a lot of flexibility from December 15 to February 15 each season. We can work around your schedule.
Thanks again for the great questions. Should you have any more, do not hesitate to contact us again.
Untill the next time,

Flat Roof Membranes: Sample Customer Query

Below you will find a customer inquiry we had in Fall 2011 referencing flat roof membranes for a new inner-city home our customer is having constructed in Calgary, Alberta.

This fellow was the unfortunate recipient of what occurs in the flat roofing industry every year – there is a year-end tsunami we as roofers experience when panicking clients need to have their flat roofing systems maintained, replaced, or repaired. It turns into an “all hands on deck” period of time during this so-called tsunami, especially for our commercial roof and industrial roof clients. This particular flat roof membrane query unfortunately took some time to return, but the client was gracious nonetheless. Please note that the quoted blocks in italics are our responses to the client’s questions.

< Start of Email >

Well thank you very much for the in-depth follow-up, it is much appreciated.
I do have several questions, some of which may overlap with others. Please bear with me, my inexperience with flat-roofing necessitates a bit more research, and there seem to be so many systems that it is difficult to know which is more appropriate than the next.
1. With the liquid rubber roof coating system, will the membrane simply seal around any punctures in the roof (i.e. irrigation line for the planter box, roof skylight openings, scuppers in the parapet), or does this require separate attention?
Liquid Rubber roofing, at least the specification GRS applies liquid rubber roof coating to is a process of steps. The first being cleaning the substrate or roof deck, next is preparing all roof penetrations, fasteners, expansion joints, connections, etc with a scrim fabric sheet (polyester woven scrims) and trowel grade liquid rubber (done by hand with trowel, squeegees, and rollers), then a flood coat of liquid rubber (sprayed), and then the final stage of liquid rubber roof application is a final spray coat of liquid rubber. Another coat is optional to add colour. This is done with an acrylic top coat. The liquid spray on acrylic roof coat can be specifically tinted to the desired color.
2. Do you recommend, as per the liquid rubber system, a 2-layer approach (using the Sealroof A-100 over top the Sealroof B-200), in the same way you would do a 2 or 3-layer torch on system? In this way, you could apply a white top-coat < GAF Top Coat > to help reduce the heat island effect on the roof and help alleviate the temperature variation in Calgary?
The GRS process of application for liquid rubber roofing, flat roofing, and pitched roofing is typically more involved than most specifications our roofers see day-to-day in the marketplace. Specific to Liquid Rubber roofing, our system of application is detailed at point 1 above. Top coating the liquid rubber is also detailed above and there is an article linked to our website specific to the white and black decision with flat roof membranes found here (Carlisle-Syntec Article).
3. My current details include a sloped insulation for added R-value, over top of a ventilated ceiling cavity with vents in the parapet wall. Who do you get your sloped insulation from, and is it custom made for the project, or does it require labour to adjust it? Is it possible to simply install sleepers above the roof joists to achieve slope and sheath the roof and apply the membrane overtop of that, and sacrifice the added R-value of the sloped insulation? Is that normal?
Sloped insulation for flat roof structures is a common method. Many designers will specify the framing of the substrate to be sloped also as an alternative. We source our sloped roof insulation from a number of companies. One we often use in your area is Plasti-Fab. It is a pre-engineered sloped insulation that is delivered with a diagram for installation. We would have difficulty answering to the roof sleepers question until on site or more discussion was had.
4. You mentioned custom metal flashings, and I am wondering what the scope of your roofing will entail (in other words, do you also provide flashing around skylights, and around scupper holes for drainage)?
Various roof flashing required we provide to our flat roof customers. Typically, roof skylights will have flashing kits, but various designs will have us custom fabricating metal. Whether it is flat roof cap flashing, cant flashing, edge flashing, or various custom flashing for roof membranes… we fabricate and install it.
5. You mentioned the TPO system (which I have been recommended to use from a colleague) is more suited for Vancouver than for Calgary. What are the reasons for this? Is it strictly based on freeze/thaw considerations or total precipitation, snow loads, or some other reason? One of my biggest concerns is that the roof membrane will not stand up to the temperature differentials we all know that Calgary is susceptible to.
Answering to the environmental impact to various roof membranes (such as freeze thaw) is a complicated topic. SBS Modified Bitumen (torch on) and Built Up Roofing (Tar and Gravel) has been a mainstay for so long, with Alberta holding to it longer than most other areas of the world. My comment to TPO or any roof membrane that is reflective or light colored is more specific to the energy efficiency of roofing systems or flat roof membranes. In Alberta, many see it as counter productive to have a reflective roof as more often than not we have our heat on than we do the air conditioning. This too is a diverse conversation. Our web site under the flat roofing section on the right column has links to articles. With respect to how each membrane will hold up specific to Calgary, that is a difficult question. TPO, PVC, EPDM single ply flat roof membranes are being installed every day in Calgary, as are the traditional SBS modified and BUR flat roof membranes. SPF – Spray Foam Roofing is another roof membrane option and then the Liquid Rubber roof membranes. At issue is that most roof membranes have not been installed for a long enough duration in the Calgary market for an excellent evaluation of performance. For example, the liquid rubber we are referring to in this instance has only been available for shy of a decade and not widely used until very recently. Our comfort is in that we simply add more liquid rubber membrane if there were to be failures. When single ply membranes were first introduced the remediation of early failures in the membrane was much more complicated than with liquid rubber roof membranes – with liquid rubber we simply apply more liquid rubber if failures were to occur. In saying all of that, we have significant liquid rubber roof membrane applied over the last 3 years with no failure to date.
6. Is a Torch on SBS system the only one which requires a ballast? Or does the liquid rubber also require a covering to reduce UV penetration, etc? Would adding Ballast prolong the life of some of these other systems?
Ballasting a roof membrane is for the purpose of keeping the roof membrane to the roof deck – wind uplift etc. For example, a ballasted EPDM roof membrane holds the EPDM down so the wind doesn’t take the membrane away. The EPDM is adhered at the seams and loose laid to the insulation or roof deck with the roof ballast (rock) covering the membrane. Inverted loos laid systems have the roof insulation laid on top of the EPDM roof membrane with the rock or roof ballast on top of the insulation. Single ply roof membranes (EPDM, TPO, PVC) can be mechanically fastened (not requiring roof membrane ballast), Loose Laid (requiring roof membrane ballast), or Fully Adhered (not requiring roof membrane ballast). With SBS Modified Torch on roofing their is no ballast required as the SBS membrane is torched or fastened to the system by way of torching or with adhesives etc. The UV is not an issue also with SBS Modified Roof Membranes as the cap sheet (or second layer of roof membrane) has granules attached that keep UV away from the Bitumen. With Built Up Roof Membranes (or BUR) the layers of bitumen are covered with an inset top layer of gravel to keep the UV away from the bitumen in the roof membranes (typically a four layer membrane system). The gravel in this instance is not for ballasting, it is only for the purpose of UV resistance. In the case of Liquid Rubber Roof Membranes, the liquid rubber manufacturers claim UV resistance with-out the requirement of granules as with SBS membranes or gravel as with BUR or Built Up Roof Membranes.
7. Do you have specific price per square foot values for each of these products, or is the quote system more complex than that (in terms of metal flashing, scupper detailing, etc.)?
Specific pricing for flat roof membranes is wisely derived after review of the construction drawings and discussion with the parties that can affect construction processes. In your instance, specific pricing for the various roof membranes can be accomplished by way of the construction drawings provided.
It seems from your email that the liquid rubber system is more costly initially and less costly over the lifespan of the roof. Can you list the roof systems according to their initial cost for installation? I am very interested in the liquid rubber system, but a little hesitant regarding the price. My understanding was that a modified Torch-on SBS was cheaper than some of the other systems, like a TPO membrane or a soprema system.
Pricing for all flat roof membrane systems are similar. Tar and Gravel Roof membranes (or BUR) will tend to be more costly due to the extensive labour, SBS Modified should be similar or perhaps a touch more than the Single Ply roof membranes (TPO, PVC, EPDM), TOUGH ROOF (which is a concept built on the strength of the traditional Built Up Flat Roof with an elastomeric top coat) would be on the higher side of the pack, and Liquid Rubber systems (if done per the specification of membrane application that we use) will be in line with Single Ply. More often than not, with roof membrane choices and pricing, you will receive varying opinions that are usually specific to what the roof membrane applicator installs most, what roof membrane the roofer is certified to install, etc. The widest divergence we see in flat roof membrane pricing is not necessarily the roof membrane material that will be used, but the process of application of the roof membrane itself and whether the flat roofing company has all the other operating costs that credible flat roof companies can have due to safety, staff remittances, benefits, company vehicles, licensing, insurances, etc.
My roof works out to be about 1150 sq. ft. (inside parapet), with the planter on the second storey being about 23 sq. ft. Would you be able to work out a few prices using the Torch-on SBS, liquid rubber, EPDM, and Soprema systems that you install?
As it applies to SBS Modified, we typically use when available to us the IKO SBS Modified Bitumen products vs Soprema. Not that we see IKO superior, it is just what our company typically uses for SBS roof membrane unless specified otherwise. I am personally a Soprema certified installer and I don’t see much of a difference either way – both IKO and Soperma produce a quality SBS Modified Roof Membrane as I see it. With EPDM, we regularly install Firestone and Mulehide EPDM (I believe Carlisle manufacturers the Mulehide EPDM, but I could be wrong). With TPO we install Firestone and Mulehide regularly also. Liquid Rubber roof membranes come in various forms, because we are installing so much of the liquid rubber roof membranes we have various specifications for application and material for the membranes. I will price yours specific to how we see it best applied and according to the manufacturer(s) we see as best for your roof membrane.
The pricing for the various roof membranes I will forward in a separate email.
Thanks again for your comprehensive response. You’ve been most helpful.
