Photo Journal: Flat Roof Leak Inspection Edmonton AB, March 2014

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.
