Our Flat Roofing Process

1

Membrane Assessment

Our inspector checks every detail: ponding areas, seam separations, flashing failures, clogged drains, UV degradation, and blistering. Core samples test insulation moisture content. You get photos and an honest assessment.

2

Detailed Proposal

We present options, not ultimatums. If a repair extends your flat roof 5-10 years, that might be the smartest investment right now. If the insulation is waterlogged and the membrane is failing, replacement is the answer. We lay out the facts.

3

Expert Flat Roof Crew

Insulation board cut and installed with staggered joints. Membrane installed over insulation per manufacturer specs. All penetrations (pipes, vents, HVAC curbs) receive custom-fabricated flashing. Drains and scuppers cleared and properly connected to the new membrane system.

4

Final Inspection

After installation, we verify drainage by checking water flow to all drain points. No ponding. Every seam tested. Manufacturer warranty registered, 15-20 year coverage depending on system and build-up.

Why Choose Osco Roofing & Maintenance for Flat Roofing?

Core Sampling & Testing

Before recommending replacement or coating, we core sample the roof to check insulation moisture. Waterlogged insulation means tear-off. Dry insulation means options.

All Flat Roof Systems

TPO, EPDM, PVC, modified bitumen, built-up roofing, and coatings. We install the right system for your building, not whatever we have on the truck.

Electronic Leak Detection

We use electronic testing to pinpoint flat roof leaks without destructive investigation. Find the source, fix the source, move on.

Manufacturer Warranties

15-20 year manufacturer warranties on new flat roof installations. Coating systems warrantied for 10-15 years. All backed by certified installation.

Flat Roofing FAQ

Yes. Semi-annual inspections checking seams, flashings, drains, and membrane condition prevent small issues from becoming expensive repairs. Drain clearing is especially important. Clogged drains cause ponding that damages the membrane.

Usually, yes. Most flat roof leaks originate at seams, flashings, or penetrations, all repairable. If the leak is from widespread membrane failure or waterlogged insulation, replacement is the better long-term solution.

Ponding happens when the roof lacks adequate slope to drains or edges. Causes include compressed insulation, clogged drains, building settlement, or the original installation didn't include tapered insulation. We fix it with tapered ISO boards that create positive drainage.

About Our Osco Flat Roofing Services

TPO is our most-installed flat roof membrane. White reflective surface reduces cooling costs, hot-air welded seams create a watertight bond stronger than the membrane itself, and manufacturer warranties run 15-20 years. We install 60-mil and 80-mil TPO, fully adhered or mechanically attached over polyiso insulation.

Roof coatings can extend the life of an existing flat roof by 10-15 years for a fraction of replacement cost. Silicone coatings over TPO, EPDM, or metal work well when the existing membrane is still in decent condition. We core sample and moisture scan to make sure coating is the right call before recommending it.
