TPO, PVC & EPDM Roof Restoration | PermaBest Single-Ply Coating

Single-Ply Roof Restoration: Quick Answers

• PermaBest revives aging TPO, PVC, EPDM, and Hypalon single-ply roofs indefinitely without tear-off, bonding directly to the existing membrane.
• Single-ply roofs fail first at heat-welded seams and flashings — PermaBest seals every seam under one continuous liquid membrane.
• Restoring a single-ply roof with PermaBest avoids tear-off, keeping the building watertight during work and old membrane out of the landfill.
• PermaBest can also serve as a stand-alone fluid-applied membrane — the single-'ap'ply system all on its own.
• A PermaBest-restored single-ply roof is backed by a 10, 15, or 20 year renewable warranty.

Frequently Asked Questions

Can PermaBest restore an aging TPO or PVC roof?

Yes. PermaBest bonds directly to aged TPO, PVC, EPDM, and Hypalon membranes, sealing the field, seams, and flashings under one continuous liquid film — no tear-off required.

Why do single-ply roofs fail?

Most single-ply failures start at heat-welded seams, flashings, and penetrations as the membrane shrinks and plasticizers migrate out. PermaBest eliminates those weak points by covering the entire roof in one seamless membrane.

Is restoring a single-ply roof better than replacing it?

Restoration with PermaBest typically costs far less than replacement, keeps the building watertight during the work, avoids landfill disposal of the old membrane, and delivers a renewable 10-20 year warranty.

Does PermaBest adhere to weathered EPDM rubber?

Yes. With proper cleaning and priming, PermaBest achieves a full bond on weathered EPDM as well as TPO, PVC, and Hypalon, forming a monolithic membrane over the old roof.

Can PermaBest be used instead of a single-ply membrane on new work?

Yes. PermaBest can be applied as the stand-alone waterproofing membrane — a seamless fluid-applied alternative to sheet goods, with no seams or fasteners to fail.
