Common Causes Of Commercial Roof Leaks

Posted on

Water damage is one of the leading causes of commercial roofing damage. The water damage can result in the rotting of roofing components such as shingles, which weakens your roof structure. Excess leakage can also cause financial losses. For instance, the water might cause your machinery to rust, slowing down operations. Additionally, if your storage area is damp, you risk product loss because molds can form on your products. Therefore, you need to understand the leading causes of commercial roof leaks to avoid these problems.

Poor drainage

During the roof installation process, commercial roofers need to plan for proper water drainage. When water accumulates on your roof, the water starts seeping through the roof, and you might observe some water droplets inside your house. You might also experience dampness in your work area. Additionally, the pools of water add extra weight to your roof, and the excess pressure can result in the collapse of your roof over time. Therefore, there is a need to install roof gutters and drains that direct excess water away from your roof during a heavy downpour. After installation, these water draining channels need frequent cleaning as gutters are prone to blockage by fallen leaves and silt.

Damaged Commercial Roof Membranes

The roofing membrane is the water-resistant layer that prevents leakage. Harsh weather elements such as heavy snow can damage this membrane. When water leaks through the now permeable membrane, the underlying commercial roof insulation becomes saturated with water, and the water starts leaking. You need to either repair or replace the membrane to prevent further water leakage.

Old Roofing

Commercial roofs have a lifespan of between 10 and 40 years, depending on the roof type you install in your business structure. As your roof ages, the roof becomes more susceptible to damage. Exposure to extreme hot and cold temperatures can cause cracks that serve as water leakage points. Additionally, mechanical damages such as roof punctures and roof corrosion can also cause leakage. Hence, you should consider replacing your roof when it gets old.

Open Roof Penetrations

Commercial buildings have penetrations on the roof membrane to pave the way for gas lines, electric wiring, vents, air conditioning units, and even gas lines. These open penetrations can also serve as water entry points to your business structure. Therefore, have your commercial roofing company inspect the penetrations regularly and seal up the openings.

Old age, poor drainage, damaged roofing membrane, and open roof penetrations are significant causes of commercial roof leaks. A commercial roofing service can help you solve the problems and prevent leakage.
