How to Repair a Leak on a Flat Roof

A flat roof can be repaired with a simple patch, or more complexly by replacing the membrane of a building. If your building has suffered damage due to the weather, the insurance claim can be complicated, and the reconstruction or repair of the roof is also complex.

Asphalt Flat Roof Repair

Cracks and blisters are the most common problems on an asphalt roof. These are caused by moisture in the tar. For a quick emergency fix, Rust-Oleum can be used to seal the hole. The long-term solution is to install a new felt patch on the roof that will be heated and melted into place.

Concrete Flat Roof Repair

Over time, concrete can crack and cause leaks in many buildings that have a roof made of concrete. If you are inspecting your roof, remove any surface wear so that you can find cracks to repair. Use bitumen primer to temporarily cover the area. You can seal the crack with a roofing felt by torching it in place.

EPDM Rubber Roof Repair

Rubber-based roofing systems are plagued by tears and cuts. The result is a roof that has cracks, holes, and cuts. You can use a lap sealing agent to fill in the gaps. However, you should not apply too much as it may require extensive repairs later.

Flat Roof Repair Using Felt

This roofing system is one of the oldest and most reliable. It can be damaged if it gets punctured by debris or if its felt splits due to age. As well as leaking flashings, which are part of the roof seal, leaking at the edge can also be a problem.

Fibreglass Flat Roof Repair

Cracking is the biggest problem with a fiberglass roofing system. It occurs around flashings, and on the walls of the building where the roof is attached. The board joints, trim, and upstands can all be damaged. For any of these issues, the quick fix is to wash the board with soapy water and then apply an acrylic sealant on top of the crack.
