Felt Flat Roof Leaking: Causes and Repair Decisions

Leaks on felt roofs often begin at laps, edges, upstands, penetrations, splits or areas stressed by standing water. The indoor stain may be some distance from the actual entry point.

What to inspect

• Open or lifted laps and perimeter details.
• Cracks, punctures and exposed reinforcement.
• Blisters or soft areas that may indicate trapped moisture.
• Outlets, gutters and places where water remains after rain.

Repair or professional assessment?

A clearly defined defect surrounded by sound material may be repairable. Widespread cracking, repeated leaks, saturation or an unstable deck needs professional assessment and may justify replacement.
