How to Spot a Leak on Your Commercial Roof
Concern about leaks on a commercial building’s roof is a common concern we hear, especially as the rainy season approaches in the San Francisco Bay Area and throughout Northern California. If you are worried that the roof on your commercial building is in danger of leaking, act now to schedule an inspection, and if needed, make critical repairs before it starts to rain. Immediate action can reduce repair costs and avoid potential interior damage.
Here are five signs to look for that may indicate your roof is in danger of leaking:
1. Membrane Damage
The membrane functions as the roof’s cover. The membrane can crack, split, or shrink over time, which can cause it to leak. It can also be damaged by a tree falling on it. It’s advisable to inspect the membrane often and repair it when needed.
2. Old or Damaged Flashing
Flashing protects the edges of the membrane. Flashing expands and contracts depending on the weather. This can make it tear and then the joints and seams are susceptible to leaks. They can also become loose during storms. If flashings are old, they were not installed correctly, or they have been damaged by changes in the weather, then water can get into the roof system.
3. Open Penetrations on Building’s Roof
Many flat commercial roofs have penetrations such as HVAC units, vents, drains, pipes, and other systems. These can be areas for leaks if they were not sealed well when the roof was installed.
4. A Bad Smell
If you detect a foul smell in the building, it could be an indication of mold. Mold needs a moist environment to grow and that could mean that water is coming into the building. When a roofing contractor comes to inspect the building let him know so that the growth and spread of mold can be stopped.
5. Standing Water
If leaves, tree branches, and other debris clog drains, then eventually the result will be standing water. If a pool of water remains for a long time, then the roof will deteriorate, and a leak will occur.
