Flat roof ponding happens when rainwater collects on the surface of a roof and does not drain within a couple of days. If it’s left long enough, standing water can lead to the need for premature roof replacement, or at the very least, costly repairs.
Let Deschutes Roofing & Insulation help you avoid such problems. Here’s what you need to know about the causes and effects of ponding on flat roofs.
Causes of Water Ponding on a Flat Roof
There are a few factors that cause water to pool on a roof. Debris could be blocking roof drains or gutters. The pitch may be insufficient or there may be weak membranes or caulking issues. Too much roofing material on the edge of the roof and poor flashing installation are other known causes. With the help of an expert roofer, you can easily pinpoint and correct the root of the problem.
Long-Term Effects of Flat Roof Ponding
A little water on the roof may not seem like a big deal, but there are long-term effects that harm the longevity and value of your roof. Ponding can cause leaks and make the roof sag. Roofing material in prolonged contact with the water will also deteriorate faster. It can also lead to moss, algae, or plant growth, all of which can damage or weaken the roof membrane. That’s why you need to schedule an immediate roof repair service call at the very first sign of trouble.
Preventive Roofing Maintenance
Having a preventive maintenance plan in place will help you catch any ponding water and other roofing issues before they can cause more damage. It’s a good idea to have your roof checked after major weather events and to clean out your gutters and downspouts regularly.
