How to Address Water Trapped Under the Membrane on a Flat Roof

Water trapped under the membrane of a flat roof can cause significant damage if not addressed promptly. At Anchor Point Roofing, we specialize in comprehensive roof repairs for homes and businesses in Chicago, including resolving water intrusion issues under flat roof membranes. Our process begins with carefully cutting the membrane to drain the trapped water, ensuring the affected area is completely dry. Once the area is accessible, we thoroughly investigate to identify the source of the water intrusion. Common causes include gaps in the counterflashing or damage to the existing membrane. Where necessary, we repair the source of the issue to prevent future leaks.

To restore the roof, we install a new modified bitumen membrane over the affected area, sealing it for long-term durability. For added protection, we apply a fresh layer of aluminum coating, which enhances the roof’s resistance to weather and UV exposure. Additionally, we use a commercial-grade sealant on top of the counterflashing to close any gaps that could allow further water intrusion. As Chicago’s trusted roofing experts, Anchor Point Roofing is dedicated to delivering effective and lasting solutions for flat roof repairs. Whether you're dealing with water under the membrane or other roofing concerns, our team is here to help protect your property with professional, high-quality service.
