When your commercial or industrial flat roof leaks, you need to find the source quickly to reduce roof damage and interior damage. Fortunately, most roof leaks have one of the following causes:
- Poor roof drainage: All roofs, both flat and sloped, have to drain water off to prevent water damage. Gutters, flashings, and other roof components help the roof drain effectively. However, if the gutters clog or the flashings break, they contribute to poor drainage, which results in leaky roofs.
- Damaged roof membrane: Even if the roof drains well, it may leak because the membrane is damaged after being exposed to the elements without regular maintenance. Lots of foot traffic can also wear down the membrane. Flat roof membrane damage often includes tears, worn seams, ponding water, and blistered sections.
- Unsealed roof penetrations: Commercial flat roofs often have penetrations such as HVAC units, utility lines, pipes, or vents. If a roofing contractor doesn’t seal them during installation, they can lead to leaks.
- Poor roof sealing: Sometimes, your contractor doesn’t just fail to seal the roof’s penetrations—they may fail to seal the roof itself. Without proper roofing sealant in place, your roof sits exposed to water damage and many other types of weather damage.
Each of these create roof leaks that lead to major water damage to your entire facility. Spotting these problems quickly helps effectively mitigate roof damage.
