EPDM is a synthetic rubber roofing membrane. It should be evaluated as a complete roof system, with attention to seams, flashings, drainage, and the condition of the substrate beneath it.

What to check first

  • Identify whether a defect is local or widespread.
  • Check for incompatible previous patches and coatings.
  • Use an approved EPDM repair or suitable Super Silicone Seal guidance for the specific detail.

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.
