Problems with Repair 1
SBS Modified Torch on Roof / Residential / Many Problems with Installation of Roof

Here’s a report from the field today in which one of our flat roofers in Calgary, AB had run into classic torch on (SBS Modified Bitumen) flat roof installation problems. Of course, for the homeowner that has a flat roof on their home that is paying the cost for improper installation practices, this is not a positive occasion. Nonetheless, the leaks on their flat roof will now cease and the homeowners will know that their flat roof repair is completed is in good shape to serve them well in to the future – it could have been worse!

Here’s the roof repair report;

“When I arrived I spoke to both the customer and his wife about the problems they were having with the roof leaking. I walked around the perimeter of the house and they had showed me the places the moisture was coming in to their home. The roof is a SBS roof – modified torch on. I found several problems; almost all of the roof membrane seams had no bleed out, I had bent down to check and observed cap sheet was torched down past the salvage edge between 1/2 and 1 1/2 inches, and the seam is sitting on the granules instead of torched down to the salvage edge. Where I pulled up on the seam or used a trowel I could lift it up. Also any corner of the sheet I wanted to I could pull up as well. The real kicker is the perimeter edge around the whole roof was completed wrong – the people that did the roof replacement did not prime the perimeter flashing when torching to it so it does not stick to the metal at all. Also I found the capping membrane was not buttered in at the metal so there is no termination point at the roof metal, the roofing installers didn’t granulate it either because it wasn’t torched properly. The homeowner had put some sort of water proofing gum or mastic around the perimeter of the roof and has stopped whatever problems they would have had earlier, but over time (no UV protection i.e. granules) the roof is starting to crack and the roof is failing and leaking – leaks from the improperly torched roof. I had observed in one location on the roof where the SBS meets the metal at a lifted corner – I pulled it up and saw that it was a definite leak spot so I temporarily repaired with mastic and granules. The chimney and vent stack should be re-caulked as well. The home owners were very happy I was there to figure out their problems with the roof and to explain to them how and why they are having roof leaks that require immediate repair. I also told them the office will be in contact with them with reports, pics, quotes and costs for permanent repairs to the roof. ”

Roof Repair and Preventative Roof Maintenance

Roof repair season is here again in Calgary, Alberta – it’s that time of year and GRS Calgary can help with your leaky roof! Our roofing services are available in Toronto, Calgary, Red Deer, Edmonton, Lloydminster, Saskatoon, Regina, Medicine Hat, Lethbridge, Canmore, Kelowna, Vancouver, Whistler and points between.

Roof Repair Topics:
– Flat Roof Repair
– Metal Roof Repair
– Shingle Repair
– Roof Tile Repair
– Skylight Repair
– Emergency Roof Repairs

The principle of preventative roof repair and roof maintenance is just like any other. Failing to change the oil in your car will cause serious repair problems and the same applies to repairs to a roof. Preventative flat roof repair or even preventative roof tile, metal, or shingle repair is much less costly than waiting for a leaky roof problem to arise.

 

Flat Roof Repair

Flat roof repair and preventative roof maintenance is important because the failure of a flat roof can cause extreme aggravation to a commercial or industrial enterprise and to a homeowner.

The cost of flat roof repair and proper maintenance will save a flat roof owner a great deal of expense over time.

Calgary has extreme temperature swings and the weather in Southern Alberta is very tough on flat roofs in particular. Flat roof repair on the West Coast is much different than Flat Roof Repair in Calgary for example, and our flat roof repair and roof maintenance programs are expert – single source roofing solutions.

Our flat roofers are flat roof specialists – they only repair flat roofs, our flat roofers are tooled for all flat roof repair scenarios, and our flat roofers are on call 24 hours for emergency roof repair at +1.877.497.3528.

Our Calgary flat roof division roofers regularly repair flat roof systems on commercial, industrial, and residential tar and gravel, SBS modified, EPDM, TPO, PVC, and built up flat roofing systems.

Metal Roof Repair

Metal roof repair can be a frustrating roof repair scenario for building owners and roofers alike because the roof leaks can be very intermittent. Adding insult to injury; when hiring a metal roofing contractor to repair a metal roof, many people make the mistake of hiring a roofing contractor that does not know how to fix a metal roof properly.

The problem is that metal roof repairs are typically necessary due to expansion and contraction of the roof metal at the seams of the metal roof panels and also at the roof penetrations.

Metal roofs expand and contract much more than most roofing materials (especially in a climate like Calgary) and as a result metal roofs tend to leak more often and more intermittently than most roofs.

If one does not understand the inherent leaky problems that come with a metal roof and if the attempt to repair the metal roof is executed with conventional roof repair methods (say as a shingle repair would be done), this typically results in an unhappy customer as the repair won’t hold, the roof leaks again, and the building owner is back to the same problem and short some money. So more often than not, the real solution to a metal roof repair issue is simply having the right metal roofer do the roof repair. Metal roofing is a specialty roofing trade and as such it requires an expert.

We have have journeyman metal roofers that work exclusively in our metal roofing division. Our metal roofers have metal roof repair techniques and materials that a general sloped roofer wouldn’t typically possess – if there is a solution to your leaky metal roof our metal roofers will find it, show you what is occurring, and they will remediate and bring solutions to your metal roofing issues.

Shingle Repair

Shingle repairs can be difficult to assess and repair as shingles are typically on steep roofs and at times the roof itself can be quite high.

Shingle repairs are most often a result of a roof penetration leak such as a skylight, a roof vent, or roof flashing… shingle blow-offs are also a common problem with shingle roof leaks.

The problems we see with shingle repairs are more often than not a result of the original installation of the shingles and not the roof system itself (the typical issue with metal roof repairs).

Our blog is full of posts about proper shingle installations. How to shingle a roof properly seems to be an art most don’t like to fully engage. Nonetheless, there is hope because shingle roof systems work well when installed right.

Search terms such as “shingle roof underlayment”, “how to install shingles”, “installing roof shingles”, etc on our blog and a number of posts will show you the proper shingle installation procedures.

And we must not forget, one of the other primary reasons for a leaky shingle roof is the attic space and the ventilation of the roof. Here again, as it applies to roof ventilation and attic condensation, in a climate like Calgary’s, this can be especially of concern as the freeze thaw cycle and snow loads can cause allot of condensation and roof ice damming issues.

If you are having problems with roof leaks or condensation from your roof, ice damming, roof ventilation, etc be sure to search any of these terms in our search box on the left as our roofing blog has numerous posts on these common roof leak and roof repair problems.

Roof Tile Repair

Concrete roof tile and clay roof tile repair is again a specialty roof trade and as such requires a professional roof tiler. General Roofing Systems Calgary employs the best roof tilers in the roofing business and as such we can deliver real solutions to your roof tile problems.

Roof tile repairs are most commonly a result of damage to the roofing tile itself, improper installation of the roof tile, or the roof membrane under the tile. Roof tile is a watershed roofing system and if the underlay or roof membrane is compromised, so is the integrity of your roof water tightness.

Skylight Repair

Skylight repair is usually due to improper skylight installation. Skylights require proper curbs, flashing, and use of roof underlayment. More often than not, our roof repair technicians find that the flashing or the underlayment around the skylight is compromised. When water, snow, or ice back up behind the skylight on your roof, if the skylight backpan or membrane at the back side of the skylight isn’t done correctly, the skylight will leak. We should also note that a great deal of skylight repair calls we receive are actually condensation issues and not skylight leaks.

Flat Roof Repair on Your Commercial or Residential Flat Roof

Spring 2011 is finally here – I’m speaking on behalf of the Alberta and Sask residents… Calgary, Edmonton, Saskatoon, Regina, etc…. not the lucky folks in Vancouver – spring flat roof repairs in Vancouver have been in progress for some time now. For us, the flat roofing contractor, spring means that the winter holidays are over and the residential and commercial flat roofs begin to leak.

Flat roofing contractors will tell you that the spring thaw isn’t the main concern for a flat roof owner on the prairies – the main problem flat roof owners experience in Alberta and Saskatchewan is when the spring rain storms start. Your flat roof that has been through freeze – thaw – freeze – thaw – and the roof snow loads (especially from 2010/2011) is more often than not, getting to ready to leak (unless you have had a recent flat roof replacement in the past few years).

Now, if you catch it just right, which is between the spring thaw and when the rains start, you may alleviate a lot of flat roof leak issues – a proactive spring flat roof maintenance is a good idea anyway.

Nonetheless, when it comes time to repair your flat roof, or consider a flat roof replacement, we have a lot of material on our blog and website to assist you in the process.

For commercial flat roof owners, we have a document that provides you with a step by step due diligence process for commercial flat roof replacement available at this link – it’s a good read for anyone taking on a flat roof replacement:

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

For those that need to investigate various flat roof systems and flat roof membrane options, our website has a document that outlines all your flat roof membranes and systems in a one document guide to flat roof systems, it is available at this link:

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

If you want to take on flat roof repair or annual maintenance of your flat roof yourself, or if you simply want to understand the process of flat roof repair and what regular maintenance steps are required on a flat roof, we have an excellent step by step flat roof maintenance and inspection guide available at this link.

And, when considering flat roof repair or replacement this spring, remember you can call us anytime 24/7 and speak to an expert flat roofing professional (we always have flat roofers on call and available to discuss details for repair or replacement) – our 24/7 Emergency Flat Roof Repair Phone Line is +1.877.497.3528, or you can simply email us info@grscanadainc.com and we can respond to your roofing questions there. If our Emergency Roof Repair line is busy when you call, if you have access to email – send one! Our on call Emergency Response Flat Roofers all have blackberry phones and when the weather is bad alot of calls come in, and many times they are on the business phones and texting and emailing with clients on the blackberry phones about flat roof repair issues – it’s a roofers life, what can I say. Livin the dream the roofers say.

And finally, many folks have had flat roof leak problems solved right over the phone when disaster strikes their flat roof and immediate roof repair is required – just the other day a major industrial facility called in the middle of the night with serious flat roof leaks…. long story short, the facility manager learned that he could temporarily repair the flat roof himself with our direction which allowed for the time for our crews to get to their facility to repair the flat roofing system the next day.

Anyway, all the best with your flat roof challenges and solutions in 2011.

Until next time,

The Team at GRS
