One of the common problems that flat roofs face is that of moisture. However, not all flat roofs have this problem; the design and maintenance practices you have for your flat roof determines whether it develops a moisture problem or not. Here are few tips to keep moisture problems at bay:

Use a Continuous Vapor Barrier

The main function of the barrier is to control airflow through the roof penetrations. This is necessary, especially over rooms with rising humid air, such as bathroom and kitchens, so that the moisture doesn't find its way into the roof and damage the roof's integrity.

Unfortunately, joining sections of vapor barrier materials, which is what some people do, is not the best way to go about it. This is because the joints become the weak points of the barrier and often deteriorate fast. The best way to prevent leaks from the joints is to use a continuous water barrier.

Ensure All Roof Installations Are Professionally Done

Installing things on the roof is risky; in fact, roof installations are some of the most common causes of leaks on flat roofs. For one, there is a high risk of roof damage during the installations from foot traffic and accidental drops of tools. Then there is also the improper installation of flashing, which leaves small spaces around roof penetrations through which moisture can seep. Therefore, avoid DIY roof installations as much as possible. If you want to install electrical wires, television antennas, roof vents, and other roof installations, higher the services of a professional installer.

Keep the Roof Clean

A dirty roof will leak sooner rather than later whether it is a flat or sloping roof, but the leaks will occur faster on the flat roof. This is because the accumulated debris traps moisture and keep the roof perpetually wet; this gives the moisture time to penetrate the roof. Apart from that, the debris also blocks water flow and interfere with efficient drainage; this also increases the risk of leakage.

Keep the Drainage Well Maintained

Every flat roof comes with an integrated drainage system since gravity alone cannot ensure efficient drainage. However, the drainage system won't function efficiently if it is poorly maintained. For example, the drainage channels can be blocked by debris and malfunction. Therefore, regular maintenance of the drainage system is also necessary for leak prevention.

Hopefully, you will maintain your roof properly and it won't suffer from moisture degradation. Consult a roofing contractor if your roof has already developed moisture problems; the roofer will diagnose and fix the root of the problem.
