Layers of felt paper and liquid tar can last a long time. Proper slope towards the drain is crucial or pooling water can lead to leaks that can never be found.

Flashing is causing leaks

If there are trees nearby, cleaning the drain filter regularly can be your first step. If the slope is designed to guide water into the eavestrough, regular cleaning is very important. Noticing air pockets (blisters) is an indication of a leak. Blisters must be cut out and sealed with plastic cement. Leaks around the drain are the most common issues with flat roofs. Sealing around the drain with plastic cement can be an option diy project.

Leaking Around the drain

Skylight flashing and exhaust vents can be problematic also. Inspecting for cracks and sealing it with plastic cement can stop the leaks. Always tie your ladder when climbing height. A professional roofing contractor is only a phone call away.

Tar has cooked up over the years

There is a small % of roofing contractors who know how to install or repair flat roofing systems in Ottawa Ontario.

Homes built around the 1980s or prior years had tar and gravel roofing systems. Back then, it was the most popular roofing systems and it was affordable. 40 years later, these roofs need to be restored to new technology systems. New roofing systems like Modified Bitumen torchon roofs are a RedSeal specialty.

FIRE PROTECTION (PROBOARD)

Finding a leak on a tar and gravel roof can be not only challenging, also it can be costly for the homeowners. In my personal experience, I always recommend for a new roof instead of trying to bandaid and old system.

180FF BASE MEMBRANE

In order to install a new roof, gravel needs to be removed off the roof, tar needs to be removed completely, and all the flashing needs to be removed. Once we are down to the bare wood deck, slope can be adjusted according to drainage that already exists and/or address the slope to prevent water pooling on the roof.

250 CAP MEMBRANE

If the slope is good, the roof deck is in good shape, and fire protection will be the first item to installed, followed by the 180ff base membrane starting from the drain of course. 180ff membrane will be folded down onto the side walls prior to installing dripedge starter metal flashing. Once the dripedge is installed and fastened with nails, everything has to be spray primed (manufacturer recommended ) for a superior seal. The next step is to install a strip of 180ff membrane on the flashing to seal the nails and flashing to the field. Now, we are ready for the Torch 250cap membrane starting from the drain.

We only use white color membrane to maximize energy efficiency and regulate the temperature inside house as well as extend the life of the roof.
