Flat Roof Leak Inspection Edmonton - Below you will find a photo journal and emergency roof repair assessment from our Edmonton roofing repair crew at a commercial roofing site. Although the call began as a tar and gravel flat roof leak repair, the extent of damage escalated to the client requesting a quotation for flat roof recovery or replacement options. More field reports will be posted as they become available for this site. Regular Flat Roof Maintenance Will Save You Money. If you own a flat roof it is critical for you to conduct regular inspections, maintenance and repairs as needed. You will save considerable money if you do this twice per year. The reason it saves you money is that a complete flat roof replacement is expensive and 9 in 10 times had maintenance been done the replacement would not be required. If you do not do regular inspections and maintenance you could face a catastrophic failure which has occurred to this roof below. Simple spring and fall inspection and maintenance would have avoided a costly re-roof. Click here for a proper flat roof inspection and maintenance check-list. Emergency Flat Roof Inspection Edmonton, March 29 2014: Flat Roof Leaks. There are multiple large leak problems on this commercial tar and gravel flat roof that are currently being managed with buckets. Flat Roof Ponding. The roof assembly is carrying considerable ponding all over that is definitely a concern with dead weight load on the roof in times of sudden storms or in winter freeze thaw situations. Roof Drains. There are two drains on the roof that are useless; the previous contractors did not sump them properly. Roof Maintenance. Previous roof maintenance contractors did not remove the gravel before using tar to patch spots that needed repair. An excessive amount of tar has also allowed trapped air to cause blistering. Gum Boxes. Four gum boxes were actually near open water, and it was able to get into them. This is also contributing to some of the leaks. Roof Membrane. The tar and gravel roof membrane has become weather cracked from the sun, contributed by an improper ballast spread. If the pea gravel is not covering the bitumen layers the UV of the sun will dry out the bitumen causing it to crack and ultimately leak. Blisters. There is mass blistering of the roof membrane in multiple areas. If they continue, water will enter there as well. Several of the blisters on the roof are cratering water into them. Temporary Flat Roof Repairs. While we were on-site, we attempted to drain as much water as possible. The client called off the temporary repairs since the problems have become greater than simple roof maintenance work. The client has requested a quotation on roof replacement or recovery options. < End Report > Code: 109 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.

Below you will find an initial assessment for an ongoing residential site by our Edmonton roofing repair crew. More reports will be posted as they become available. Initial Assessment, July 22 2015: We arrived on-site at 1:00 pm and were lead by the client to two leaks in the shop. One was coming from around the skylight, and another one around the chimney stack in the middle near the edge of the roof. Upon inspecting the roof top-side, we observed that the acrylic MASTIC around the chimney was cracking and lifting in areas. It should be removed and replaced with seam tape and liquid rubber. The penetrations require the same. It is only a matter of time until it begins to leak around the entire skylight. There are also cracks and splits in the skylight, which seems to have had been coated with spray foam. The metal gum box also needs to be topped off. There is a metal boot top-side as well that looks like it was only spray foamed. The roof measurements are 85 ft. long by 51 ft. wide, and the skylight was 4 ft. x 4 ft. It should take 25 man hours to clean and repair the penetrations, apply some gum patch into the metal boot, and cover the foam/top up the gum box with rubber MASTIC. < TO BE CONTINUED > Code: 154 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.

Below you will find a series of field reports, quotations, and photo journals for a large industrial client in Edmonton, Alberta. Our roofing repair crew initially responded to a call for roof maintenance. Over the next two years, various sectors of the site would require complete roof replacement, gutter installations, fixture repairs, and ongoing leak maintenance. Quotation, May 9 2012:
- Engineered liquid rubber roof coating: 2-ply coat to complete roof, fastener replacement as required, sheet metal repair as required to achieve a water-tight state.
This product is the first product we have had as roofers that solves metal roof issues and has been extremely successful with considerable and complicated roof systems for a number of our Fortune 500 or multi-national clients.June 13 2012: We stopped by the shop en route to pick up a trowel, caulking, and wet dry gum (plastic cement) in case the leak was able to be fixed immediately upon inspection. On-site, the client lead us to the leak site where tiles were becoming stained. Visible sagging was noted. After removing the stained ceiling tile, it appeared that the leak was coming in around the RTU unit directly above someone's desk in the southwest corner of the top floor. Upon roof inspection, it was clear to me that the problem area was the plumbing vent in-between the exhaust fan and the RTU unit. It had previously been patched with plastic cement as a temporary solution. There are also a few other areas which could potentially leak in the future; a few gas line penetrations, gum cups around guy wire penetrations for antennae on the roof, and a few flashing issues around exhaust fans.
