Stop Roof-Edge Leaks Before They Spread One of the most common sources of water intrusion on Houston’s 3- and 4-story condominiums is the roof edge where the gutters meet the roof. Short drip edges or improperly installed gutters allow water to run behind the system and into the building. Associates Roofing Unlimited corrects these issues with precision. We install proper drip edge and correctly engineered gutters that fully protect the roof edge, stop leaks at the source, and safeguard your multi-story property. Fast, clean, and built to last.
