What Is the Step-by-Step Process for EPDM Roof Seam Repair?

1. Identify the damaged seam using a water test or infrared imaging.
2. Clean the area completely to remove old adhesive and debris.
3. Apply a high-quality primer to the seam edges.
4. Use EPDM-specific adhesive to re-bond the seam, ensuring proper alignment.
5. Reinforce with an EPDM seam tape and use a roller to remove trapped air.
6. Let the repair cure fully before exposing it to moisture. This systematic process ensures a durable repair that minimizes future failures.

When Is Professional EPDM Roof Repair Recommended?

Professional repairs are advisable when damage is extensive, involves multiple areas, or affects structural seams. Professionals have the necessary tools (infrared cameras, moisture meters) and expertise to perform repairs to industry standards while maintaining warranties. They can also advise if comprehensive roof restoration or replacement is necessary.

How Can You Maintain and Inspect EPDM Roofs for Longevity?

Regular maintenance and inspection are essential to prolonging roof life.
