Weathered EPDM: Inspect the Membrane, Seams, and Flashing

What to check first

• Check for open seams and separated penetration flashing.
• Inspect the condition of the membrane beneath old patches.
• Use an EPDM-compatible system
• do not apply Turbo Poly Seal directly to EPDM.

Choose an EPDM-compatible repair

1. Confirm that the surface is EPDM

   Check project records or obtain a qualified identification. A black roof may also be asphalt based, and a coating can disguise the original material.

2. Assess the area under the old patch

   Peeling edges, trapped moisture, or damaged membrane need attention. Do not keep stacking incompatible materials over an uncertain repair.

3. Use the appropriate system

   Do not apply Turbo Poly Seal directly to EPDM. Review Super Silicone Seal guidance or the membrane manufacturer’s approved EPDM repair method. Prepare and dry the surface completely before application.
