Flat Roof Repairs: Patch or Replace?

Fasto Roofing, located in Mason, OH, offers expert insights on whether to patch or replace your flat roof when it starts leaking. Here’s a guide to help you make the best decision for your home.

Common Flat Roof Problems

Ponding Water

• Subtle Slope: Flat roofs have a slight slope to facilitate drainage, but damage or ice dams can lead to water pooling, causing leaks, sagging, and mold growth.

Buckling

• Structural Movement: Temperature changes cause natural contraction and expansion, leading to roof buckling. This poses safety risks and requires immediate repair.

Alligatoring

• Sun Exposure: Loss of asphalt content and elasticity due to sun exposure causes the roof to crack and bubble, resembling alligator skin. Untreated alligatoring leads to further cracks and leaks.
