Repair or replace?
Many EPDM roofs can be repaired: seams re-taped, punctures patched, flashings rebuilt. If the insulation below is wet across a large share of the roof, replacement usually costs less over time. When the membrane is aging but still sound, a Conklin coating can add years without a tear-off. We’ll show you photos and tell you which makes sense.
EPDM or TPO?
EPDM has a long track record and is easy to repair. White TPO reflects more heat and has heat-welded seams. If you’re replacing a whole roof, we’ll walk you through both. See TPO roofing.
How we install an EPDM roof
- Tear-off or prep. We remove the old roof or prepare the existing surface, and replace wet or damaged decking and insulation.
- Insulation and cover board. Added where needed for a flat, solid base.
- Membrane. Fully adhered or fastened, depending on the roof.
- Seams and flashing. Seams are taped and sealed, then walls, curbs, drains and edges are flashed.
- Cleanup and walkthrough. Daily cleanup at our cost, then a walkthrough with you.
What an EPDM roof costs
Repairs typically run $650 to $3,800. Full EPDM roofs are quoted per project after a free inspection, and coatings on sound roofs typically run $3.50 to $10 per square foot. Every proposal is one all-inclusive price with permits and sales tax built in.
Payment and warranty
Roofs we contract directly with a building owner are typically billed 75% at signing and 25% on completion. When we’re the subcontractor for a general contractor, we bill through the GC’s pay-application process. You can pay through the online invoice link, by check or in cash.
Our one-year workmanship warranty starts at substantial completion and covers problems from our installation, not normal wear and tear, damage by others or weather. Membrane and material defects fall under the manufacturer’s warranty, which passes through to you.
Contacted White Rock Construction about checking our roof for possible leaks. He came out the same day and checked it out. After sealing some holes he told us it was probably wind that blew up some shingles allowing the rain to come in. Friendly and honest service.
Derek and the crew from White Rock Contracting did an amazing job on my renovation project! Reach out to them with any renovation projects you have coming up, I promise you will be wowed by their professionalism, communication and overall quality of work they do!
Wonderful company to work with! The work was as promised. They are efficient, helpful and pleasant. The work was completed quickly. We will definitely be using them again.

EPDM questions
How long does an EPDM roof last?
Commonly 20 to 30 years with upkeep, depending on the membrane, the installation and how much traffic the roof sees.
Black or white EPDM?
Most EPDM is black. If you want a reflective white roof, we’ll talk through TPO as well.
Can you repair a roof another company installed?
Yes. Most of our repairs are on roofs other companies installed. See commercial roof repair.
Do you work on EPDM in Illinois?
No. We don’t hold an Illinois roofing license, so all of our roofing is in Indiana.
