Commercial roofing

TPO, EPDM, or PVC for a flat roof?

How the three common low-slope membranes compare for Northern Utah commercial buildings.

General information from CCR Roofing, not an assessment of your property.

TPO.

A single-ply thermoplastic membrane, commonly white and reflective, with heat-welded seams. It is a frequent choice for commercial low-slope roofs.

EPDM.

A synthetic rubber membrane with a long track record on low-slope roofs. Seams are typically adhered or taped rather than heat-welded.

PVC.

A thermoplastic membrane with heat-welded seams, often chosen where chemical or grease exposure is a concern, such as restaurant rooftops.

What decides the system.

The existing roof, insulation, drainage, rooftop equipment, building use, and budget all matter. An assessment of the actual roof is the right starting point.

A few common questions

Frequently asked questions.

What do TPO, EPDM, and PVC have in common?

They are single-ply membranes used for low-slope roofing. Each needs compatible attachment, flashing, seams, and drainage details.

How do their seam methods differ?

TPO and PVC use heat-welded seams. EPDM commonly uses compatible seam tape or adhesives, depending on the system.

Is one membrane best for every building?

No. Building use, existing roof conditions, drainage, equipment, exposure, and product requirements influence the choice.

Can I switch membrane types during replacement?

A different system may be an option, but the structure, existing materials, insulation, attachment, and compatibility need to be evaluated.

What should I include when asking for a membrane estimate?

Share the building location, existing roof type if known, leaks, drainage concerns, rooftop equipment, and whether you are planning repair or replacement.
