3 Problems That Can Happen With A Flat Roof

If you own a commercial building, it most likely has a flat roof. This is because the aesthetics of a roof can often be ignored in favor of practicality on a building used for a business. Unfortunately, flat roofs are not without their own issues. Be aware of these 3 problems that flat roofs can have.

Leaking Around Rooftop Installations

An advantage of having a flat roof for a commercial property is that you can use the space to install your building's mechanical systems, such as air conditioner units. In order for any mechanical system to be installed properly, it needs to have waterproofing and flashing around the installation points to prevent leaks from occurring.

It's possible for the flashing to become weak over time and eventually form a leak. You can fix this by replacing all of the damages flashing, but you most likely will not notice the problem until water starts coming through the roof.

Clogged Drains

Since a flat roof does not have a steep slope to it, the water will not flow off the roof as quickly due to gravity. Drains need to be installed to help get the water off the roof. If these drains fill up with debris, it will cause problems with standing water around the drain's location. Ignoring the problem can potentially lead to a leak occurring.

You can fix the problem by clearing the drains regularly, or you can add additional drainage to your roof.

Standing Water

Standing water doesn't only occur around clogged drains, since they can occur in almost any part of a roof over time. This usually happens after the building starts settling, and small dips start showing up on the flat roof's surface. After a heavy rainfall, you may notice water stains in odd places that shows where the water pooled until it evaporated or leaked through the roof.

You'll need to investigate these places where water has been pooling and apply a sealant to the area. The additional barrier will help prevent water from leaking through as a short-term solution. The long-term solution involves fixing the roof in these areas so that it no longer dips inward, which could involve replacing a small section of the roof. Getting the water to naturally flow away from the area is the best way to prevent water pooling from happening.
