Whether it's a residence, a business or an industrial building, a flat roof has many advantages, but also requires some basic care, especially with regard to its drainage system. At Couvreurs de l'Est, specialists in the installation and repair of roofs in Montreal, we would like to take a moment to present to you the reasons why the maintenance of the drain of your flat roof is essential.

The essential role of the drain in a flat roof

While gravity easily evacuates water and debris from sloping structures, a flat roof must rely on a system of drains, gutters or scuppers that can do the same job. If your roof is equipped with drains, they should therefore be regularly maintained to ensure the longevity of your roof… and your building!

The consequences of a blocked drain

The number of drains in your roof and their dimensions have been calculated to ensure the rapid evacuation of massive amounts of water that can accumulate on the surface during heavy rainfall or when the snow melts. However, over time, a lot of detritus is likely to clog the mouth or the inside of the drains, thus compromising their effectiveness. A blockage of the drainage system, even partial, allows water to stagnate longer on your roof. Its erosive effect is therefore exerted without your knowledge over the seasons, affecting the longevity of the waterproof coating of your roof.

As the drainage capacity of your roof deteriorates, the chances of leaks increase proportionally. And once the water manages to thwart the protection system in place, its infiltration of course leads to a multitude of unpleasant surprises, ranging from the development of mold to structural damage to your building. In any case, you will then generally have to pay large sums to correct the situation.

Prevention is your best ally!
