Why Pooling Water Is Bad News for Your Commercial Roof
If your commercial roof tends to hold water after a rainstorm, don’t shrug it off. That standing water, also called ponding, can lead to a host of problems that quietly build over time and result in costly repairs or even premature roof replacement. When your commercial roof needs repairs or maintenance in Indianapolis or the surrounding areas, contact Two Brothers Roofing to do the job.
Why Does Water Pool on Flat Roofs?
Most commercial buildings have flat or low-slope roofs, which means water doesn’t run off as quickly as it does on a pitched roof. Poor drainage systems, clogged scuppers or downspouts, or dips in the roofing surface can cause water to stick around longer than it should.
What Happens When Water Just Sits There?
At first, it might look like a harmless puddle. But give it time, and the damage starts to show. Prolonged moisture weakens roofing materials, leading to soft spots, blisters, and cracks. Eventually, that water may find a way inside your building, damaging insulation, ceilings, and even electrical systems.
Even worse? The extra weight. Water weighs a lot—about 5 pounds per inch per square foot. A large pool can place serious stress on your roof's structure, which is especially dangerous for older buildings not designed for heavy loads.
Mold, Mildew, and Unwanted Guests
Constant dampness is the perfect breeding ground for mold and mildew. And stagnant water can attract insects and birds, who will turn your rooftop into their new hangout.
Preventing Pooling Problems
Routine inspections are your best friend. A commercial roofing contractor can check for drainage issues, re-pitch low spots, or install tapered insulation to help water flow off the roof. Drains and gutters need to be kept clear as well.
