Emergency Roofing Repairs

Wind Warnings and Torrential RainFall has been causing roof failures in British Columbia, while meanwhile in Southern Alberta high Winds are Blowing Shingles, Shakes, and Tiles off Roofs Again.

This week has been tough on roof systems from the West Coast all the way to Saskatchewan. Our call center has been over-whelmed with wind related roofing repairs calls along the West Coast including Victoria, Vancouver Island, Vancouver, Vancouver North Shore, and in the Fraser Valley. While in Southern Alberta such areas like Lethbridge, Medicine Hat, Okotoks, and even into Calgary have been experiencing wind gusts of up to 120 km/h.

The unusual high winds have been tearing shingles off roofs and causing general havoc with a variety of roofs types. We have received calls with complaints of skylights blowing off or leaking, roof vents, flashing, and even roof hatches needing repair.

With the heavy rain on the West Coast, this has caused flat roofs to fail, this particularly has applied to those that have drainage issues or drains that are plugged. With the cycles of having warm air thawing to only freeze again due to the Chinooks in areas like Calgary, AB, this has been resulted in our 24 Hour Toll Free Emergency Roof Repair line to receive several repair calls.

We are finding that Roofs with improper attic ventilation are having condensation issues to areas even as far north as Edmonton and flat roofs are requiring more maintenance to clear drains that are freezing over with ice.

Solutions for Roof Repairs, Attic Condensation, and Roof Drainage Issues

There are some solutions we can offer to help with the various problems roofs have this time of year. However If you cannot solve the repair or maintenance issue by yourself, call our 24 hour emergency roof repair toll free number at 1.877.497.3528 and schedule a repair person to attend.

Flat Roof Drainage Problems: Flat roofs unfortunately do require some regular maintenance, especially in high winds and freeze-thaw cycles.

Roof Drainage: The roof drains are prone to clog from leaves, tree branches, and with the ice and snow melting and freezing on the roof. Drainage problems on flat roofs can also be compounded by an inadequate slope of the roof. Nonetheless, a spring and fall maintenance of the roof is key to ensuring the roof bears well during bad weather. Click here to see our  Flat Roof Maintenance check list.

Roof Inspection: Extreme winds, heavy rain-fall, and snow and ice melting should trigger an inspections to be completed. It is preferable that this is completed during the storms to ensure our technician’s ability to see if the roof drains are clear.

Roof Slope Problems: With improperly sloped flat roof systems, there are solutions to mitigate these issues. An improper roof slope can be examined with our technician at the time of inspection or while we are performing maintenance to your roof.

Sloped or Pitched Roof Attic Condensation Problems Attic condensation repairs or remediation tend to be a more involved process requiring a number of steps.

Solving Attic Condensation

Your attic require proper ventilation. You need to check the intake air typically at the roof soffits to be sure that there is enough air coming in to your attic space. Be sure to check that insulation is not covering the air from entering your attic by following the air flow along the roof sheathing to where you come to the ridge or peak of the roof.

Check the exhaust vents (typically by each square foot or along the ridge) to be sure they are not plugged with snow and see if there are enough roof vents. You will need about 1 square foot of roof venting per 100 – 300 square feet of attic. A calculation commonly used by our roofers for attic / roof ventilation is 1:250. If the air vents exhausting the intake air is appropriate then you need to check the vapor barrier of the attic. It cannot be compromised and be letting warm air in.

Warm air rises through the attic into the roof sheathing. The snow on the roof then melts and creates ice dams. The ice dams then back up under shingles, shakes, and tiles causing leaks in to attics and then ultimately in to your house through the ceiling. If none of these problems can be found in your attic, it is best for you to then call the experts.

High Wind damage and Roof Repairs to Shingles, Tiles, and Shakes Repairing Damaged Roofs: Ultimately, after the installation of shingles, tiles, or shakes are complete and the winds begin to increase, you can now face blow-off problems. The best we can do is repair the windblown damaged roof.

How to Shingle a Roof: Prior to having your roof replaced, it is a good idea to know the specifications and the proper way to shingle a roof to ensure your roofing contractor is in check at time a roof replacement is required. Our website has a series on How to Shingle a Roof that explains the process of shingling for areas with high winds and how to avoid costly repairs due to wind damage.

Roof Underlay: Beyond the actual installation principles when replacing your shingles, shakes, or tiles there is the issue of the roof underlay. If the proper roof underlay is used and is installed correctly, then one does not have a concern in regards to shingles, shakes, or tiles being blown off. The roof underlay or membrane will keep the roof water-tight with-out the shingles so no leaks occur.

Shingles for High Winds: Finally, there are roofing shingles available that are designed to withstand high winds. Shingles like the Malarkey Legacy have high wind ratings of up to 170KM per HR which gives areas like the West Coast, North Shore of Vancouver, Calgary, Lethbridge etc. some advantage over the winds that damage roofs every year.
Should you have any questions or concerns regarding your roof, our office is always able to provide over the phone advice, set up inspections or arrange for a complete repair.

The inquiry below came in to our call center today, we thought it best to post it as an article to our blog to assist others who have questions regarding Low Slope Roof Membranes.

The email conversation below contains standard questions and answers that our clients have when choosing the correct “low slope roofing” or “flat roof membranes”.

The following items are a listing of the topics covered amongst the email; low slope roof life cycle costs, choosing the right roofing contractor, low slope roof prices, roof installation quality, choosing the right flat roof membrane, differences between various flat roof systems, and many more.

RE: A roofers perspective of low slope / flat roof costs, life cycle costs, torch down 2difference between flat roof systems, and most importantly  roof craftsmanship.

Email Conversation:

Hello,

I am presently in the middle of preparing to build a new office space with a low slope. My architect was advising the TPO material for it being more “green” and its heat reflection.

 However,in my internet search, the results and outlook for TPO roofs is still in question. I am looking towards the old standby 2 ply SBS and I writing this letter to you as you do all these products.

 Which one would last longer and what is the cost difference between the 2 products… also include PVC if you can.

 Regards,

 

Dear valued client;

Thank you for your inquiry.

We have been receiving a lot of the same sort of inquiry lately (what are the cost of flat roofs, the life cycle cost of flat or low slope roofing, and the difference between low slope or flat roof membranes).

Generally we tend to receive these types of inquiries at this time of year, this is primarily due to commercial, industrial and home owners having time to complete research as a result of the holiday season.

With saying that, I am going to post your questions about low slope roofing to our blog along with my answers (in article form) so that our conversation(s) will assist others when researching about low slope roof membranes and roofing contractors.

Your “Roof Life Cycle Cost” will be determined as follows: 90% will be a result of the roof installation quality and 10% will be determined from which low slope roof membrane is selected.

For every ten hours you put in planning for your new flat roof, nine of those ten hours should be researching and selecting the right contractor for your project. If you put in a total of 5 hours planning your flat roof project, 30 minutes should be spent considering the different flat roof membranes available and 4.5 hours should be spent researching, selecting, and communicating with your new flat roofing contractor.

The most important aspects to considering a Flat Roofing Contractors is; Roof Workmanship Quality, WCB, BBB reports, Insurance, Liability, Warranty, Guarantee, Safety programs. Although it is not necessary that the flat roofer is a member of the BBB because complaints can be lodged whether a company is a member or not.

Random consumer complaints are not that important due to the fact that anyone can rant about anything online (It is impossible to make everyone happy 100% all the time), yet complaints to the BBB should be given serious consideration as the BBB has a highly professional process required for authenticating complaints.

The workmanship guarantee is to be considered one of the greatest factors to take into consideration.  In some ways this is even more important than the roof membrane manufacturer warranty.

Alongside this there are other considerations to keep in mind such as insurance coverages for example:

A) Work Safe / WCB clearances (you are able to get one from Worksafe / WCB),

B) Commercial Liability Insurance (which should be 5,000,000.00 – some go as low as having only 2,000,000.00 insurance),

C) Roofing Contractor’s Safety Program (which ensures the workers are actually being safe while on your site including the use of hard hats, vests, harnesses, daily hazard assessments etc.)

These are all important considerations that help protect the customers. An injury to a worker can be a significant issue for a home or business owner if the roofing contractor has not followed the proper compliance procedures. Such an event like this can cause you considerable expense and aggravation.

TPO Roof Life Cycle Costs

Now in regards to your question pertaining to TPO Roofing and life cycle costs, unfortunately this is still unknown. Perhaps not scientifically, but from a flat roof installer perspective it is.

Statistically speaking, we have more data specified to PVC roofs than we do TPO. The reality is that all low slope roof membranes have similar life cycle costs. Yet when you consider them statistically or scientifically they do vary, but all in all, low slope or flat roof membranes all perform quite well.

However, coming from a “roofer’s perspective”, here is what I can tell you; An issue that we as roofers see every day on the roofs, which in truth should be your highest priority in research is the actual installation of the material itself. Numerous building and home owners alike are unaware of the actual process, procedures and potential roof failures due to improper installation of the flat roof.

Another area of concern is the other workers that will attend the roof during construction or after, such as HVAC installers for an HVAC retro-fitter.

Now with the assumption that the contractor is reliable and adheres to all the proper regulation, the reality is that things can happen when a flat roofs are being installed. No company is flawless and has a perfect flat roof installation every-time.

In the offices, we here several conversations about how things can and do go wrong, yet it is how we deal with the problem that separates us from success or failure with other roofing contractors. We see time and time again, people that do not do their proper due diligence because they assume things should just go without incident. Although this is not like buying a car. Hiring a trade is much different.

Of course on the other side of managing roofers or the installation of flat roofs is that there is the pro-active side of things that says there are things that we can do as the roofing contractors before problems arise to assist in a higher probability of a proper roof installation occurring.

Now, in our instance we have done things like institute our industry with an Unconditional Lifetime Guarantee which causes our roofing staff to be more aware of the day-to-day incidents that could occur. It is our responsibility to provide superior roof craftsmanship. This has our staff in a more stringent project path for a flat roof installation quality control system. Ultimately, the craftsmanship itself is what most determines the true cost of your flat roof and not which flat roof membrane or flat roof system was chosen.

Once you get past the issue of the quality of installation for your roof and hiring the right contractor you can then consider which roof membrane to use.

Now to provide some answers specific to your questions, here are some considerations for your low slope roof membrane research;

 

With respect to traditional low slope roofing (SBS, TPO, PVC, EPDM, BUR) I would recommend using 2 ply SBS modified with complete confidence.

The reason is that with a single ply, you have opportunity for what we call catastrophic Failure. In other words, a hole the size of a quarter in the membrane can cause significant damage to the complete system as the water can travel. With SBS, it is torched down and the opportunity for water migration is less. Here’s one other factor to consider with SBS modified, if you have roof installer that does not install the membrane correctly, this will result in you having significant issues. The deficiency list can be considerable and cost more than replacing the roof in the first place.

Now, You didn’t ask about multi-ply low slope roofing specifically, yet I am going to take the liberty of giving you a couple of thoughts regarding those systems. You are able to get a multi-ply low slope roof like the Tough Roof System that will give you the reflective values you desire. Additionally, you will get the sense of security knowing your roof will have maintained durability. The Tough Roof is a multi-ply built up (BUR) roof system that has layers of bitumen (in this case a synthetic layer in between instead of the traditional felt mats between each layer) and on the top, Tough Roof uses white elastomeric roof coating which contributes to the reflective component.

The other option you have in these newer systems is a multi-ply liquid rubber system which is VOC free, completely environmentally friendly and you can cover it with an acrylic reflective top coat. The system is a proprietary system from General Roofing that includes 2-4 layers of liquid rubber with a synthetic fabric between layers of built up and with an optional top coat of acrylic reflective roof coating. Of all the systems you can get, this particular system is most environmentally friendly, it is bullet proof like the built up roofs, and it can be as reflective as you choose.

So ultimately your choices are; traditional 3-4 layer built up roofing (Tar and Gravel) which is 3-4 layers of tar with tar felt paper in between, then the 2 ply modified bitumen which is torched down, the single ply roofing (EPDM, TPO, PVC) which is mechanically fastened, fully adhered, or ballasted, and then the newer type of built up roof like the Tough Roof which is 3-4 ply of tar with synthetic fabric between the layers with an elastomeric top coat for reflectivity and the newer built up liquid rubber systems from GRS that are 2-4 layers of built up liquid rubber with a synthetic fabric between the layers with the option of a reflective top coat of acrylic elastomeric roof coating.

From least expensive to most expensive the roof membrane systems typically go from least expensive to most costly as follows; Spray Foam, EPDM, TPO, PVC, 2 Ply, GRS Liquid Rubber BUR, Traditional BUR, Tough Roof. However, it is important to note when considering the cost of a flat roof or a low slope roof system two things. First, the cost difference between flat roof systems as you go from one to the next is small in comparison to expected life cycle cost planning. For example, EPDM roofing is moderately more costly than Spray Foam, and PVC moderately more cost than TPO and on and on as you go through each system. Yet the important consideration is the cost of the roof over a period of time. A properly installed Tar and Gravel roof or properly installed 2 Ply SBS Torch on Roof will likely last much longer than EPDM, TPO, or even PVC – “likely” has a number of considerations…. weather, application, service workers on the roof, etc. And a Liquid Rubber Built Up Roof and the Tough Roof built up systems have almost unlimited life cycle as they both come with maintenance agreements to renew the top reflective layer of elastomeric coating.

I hope this has helped answer your questions, please feel free to contact us any time should you require more information or would like to ask us more questions.

Until next time

Rooftop Patios, Decks, and Terraces

General Roofing Systems Canada provides roof repairs throughout Canada. Roof Repairs 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.

Flat Roof Patios – Roof-Top Patios, Decks, and Terraces Roof Top Patios, Decks, Terraces

The challenge with an outdoor patio or deck on a flat roof is that the waterproofing material or membrane used on the substrate/decking has to be done perfectly. The drainage for the low slope, and the decking material put on top has to be precise

(Some patios we service are on a flat roof itself or on a terrace balcony, while others could be on a garage.)

There are various types of rooftop decks and the different waterproofing membranes that can be used. There are flat roof membranes such as 2 ply SBS Modified Bitumen, 4 ply Built up Roofing, EPDM Rubber Roofing, PVC which is a

poly vinyl chloride, TPO which is thermal plastic. There are also products that can be applied to seal a substrate such as a concrete substrate with membranes like hot applied rubber asphalt systems and cold applied liquid rubbers (elastomeric coatings etc.)

The next issue that you would face on a flat roof would be the drainage issue. All repairs would need to be done with extreme precision in order to allow the proper drainage and slop.

After you have chosen the type of rooftop deck, the appropriate waterproofing membrane for on the substrate, and the drainage is correct. You then have the issue of what you place the membrane on itself. You will need to determine if any decking material on the membrane is required. We have seen customers use a variety of surfaces on rooftop patios, with everything from ceramic tile, paving stones, treated lumber, composite tiles, to Spanish tiles and granite.

Our recommendation to those looking at repairing, installing, or replacing a rooftop patio is to speak to a waterproofing expert first. The Home Depot or Lowes store decking material associate may be able to provide some suggestions on what tile to use, yet they may not understand the proper flat /low slope roof waterproofing and drainage practices. Roof top waterproofing for a deck system is different than normal flat and everyday roofing. With rooftop decks and patios the two worlds meet. The staff at General Roofing Systems Canada can assist you in designing a rooftop patio system that should last 20 or more years. In order to achieve these results, it is vital that owners do not try to take the least costly way out. When Owners begin to cut corners in an attempt to save costs that is where the errors occur and end up being more costly later on due to future repairs.

Below we have a report that came in to the GRS office from a roof repair technician. It shows a rooftop patio that is not very old and was installed incorrectly. Due to the improper installation, the owner is now having to pay for costs that could have been avoided. As a result of this the deck material, patio’s flat roof membrane and the sheathing/substrate will have to be removed and replaced. There is even the possibility of remediation for mold and trusses being replaced.

We hope that this article will help home owners to be more aware when purchasing decking materials and to contact a waterproofing specialist first. This tip will help you to enjoy your patio/deck for years to come without the need for repair.

Initial Client Inquiry:

I have a 300 sq. ft. rooftop deck that currently is leaking.  I was wondering if I can get someone to have a look and estimate what is required to resolve the problems we are having.

Assessment, July 27 2011:

The roof top deck is having leak problems. The rooftop deck is 95% tiled. Under the patio tile is a  deck-type waterproofing membrane and then plywood substrate. The worst area of the rooftop deck is in front of the sliding doors of master bedroom. It is not tiled. The roof top deck is covered in a paintable rubber deck membrane (low cost liquid coating). Where the tile and deck meet is a metal flashing that is letting water in. The wood decking is rotted. Not sure if you can put grout on PVC decking material, I suspect when the rooftop deck was originally tiled this is probably what caused the problems. The homeowners don’t want the ceramic tile on anymore. To fix this rooftop terrace/deck it needs a whole new rooftop deck replacement. The deck needs a tear right to the substrate and inspection of the substrate wood. This terrace is unable to be repaired and will required a full re-do

Commercial Roof, Insulation for Flat Roof2
Commercial Roofing: 1.877.497.3528 | General Roofing Systems Canada

With the temperatures in Edmonton, Alberta being close to 30 degrees, our commercial crews were faced with the challenging task of having to unload several materials onto a roof in busy downtown. This task was exceptionally strenuous due to the heavy/large capacity of materials such as; engineered sloped insulation and craning flat roof materials.

Commercial Roofing2
Commercial Roof Insulation

Our crews had to shut down and block off a section of the downtown core due to requiring; two sloped insulation semi-trucks, one crane and another large semi that held the extra materials. Despite the chaos of the job, our Crews were able to complete the task within a short time span. The commercial roof that the materials were loaded onto, is now ready for replacement. Over the next month one will be able to notice the transformation taking place.

Due to the extreme heat several roofing crews along with GRS’s, were ending shifts early. When the temperatures are close to 30 degrees on the ground level, you can almost guarantee that the temperatures on the roof will be closer to 50 degrees, if not higher.

This will be an ongoing project with GRS, We hope to post pictures soon as the job progresses.

The photo above shows EPDM up the roof parapet walls, across the top of the parapet, terminating on the front side – giving the roof membrane a monolithic type seal. The metal cap flashing will be installed next and finish this Commercial Roof System in the coming days.

The commercial EPDM membrane installed at this site is a Carlisle EPDM Membrane labelled under the name Mulehide EPDM roof membrane.

The photo to the right shows the ISO flat roof board mechanically fastened prior to the installation of the fully adhered EPDM. The walls (parapet walls) were covered with plywood to comply with the EPDM manufacturer specifications (the parapet walls of this commercial roof are concrete). Prior to installation of the mechanically fastened ISO, the Built Up Roofing System was scraped of the gravel (Tar and Gravel Roofing) and the layers of Built Up Roofing were ripped or removed and disposed of.

The photo above shows the completed commercial EPDM membrane fully adhered to the ISO. The metal cap flashing will be placed next to both protect the parapets and also for curb appeal.
