It’s that time of year again when it's rainy, cold and miserable, and who hates the bad weather more than us? Flat roofs. Based on our experience, there are some common problems that can occur with flat roofs over time. Being aware of these potential issues can help building owners spot trouble early and take preventative steps.
Standing Water and Ponding
One major problem we often see with flat roofs is standing water and ponding. When water doesn't properly drain from a flat roof, it can lead to premature failure of the roof membrane. Ponding water causes excess weight stress and will find the lowest spot on the roof to accumulate. This pooling moisture enables damage from the elements. Regularly inspect your flat roof after rainstorms and clear debris from drains to allow proper water runoff. Signs of poor drainage include warped decking and water stains on ceilings below.
Blistering and Cracking Membrane
Blistering and cracking of the roof membrane is another common flat roof problem. This is often caused by trapped moisture, fluctuations in temperature leading to expansion and contraction, or inadequate attachment of the membrane. Blisters may start small but can rupture and cause bigger issues if not addressed. Look for bubbles, splits, and cracks in the membrane surface.
Punctures and Fastener Backouts
Punctures and fastener backouts are other flat roof vulnerabilities to keep an eye out for. Foreign objects, foot traffic, hail, or wind events can puncture the weatherproof membrane. Meanwhile, fastener backs can deteriorate or loosen over time leading to roof leaks. Make sure all utilities, vents, and rooftop equipment are securely installed and avoid unnecessary foot traffic when possible.
