Flat Roof · EPDM

The rubber roof that
just keeps going.

EPDM is the rubber membrane that built the flat-roof category: large sheets, very few seams, and a service life measured in decades. The workhorse skin for a flat or low-slope roof, on a house or a commercial building.

What it is

A single-ply rubber roof, in big sheets.

EPDM is a synthetic rubber membrane that comes in wide rolls and goes down in large sheets, which means a finished roof has far fewer seams than a shingled or paneled one. Fewer seams is the whole point: every seam is a place water wants in, so a roof made of big rubber sheets has less to fail. It can be fully adhered to the deck, mechanically fastened, or held down with ballast, and it has been proving itself on flat roofs for decades. It is the call when you want a flat roof that is simple, proven, and long-lived rather than fancy.

The seams

Big sheets mean less to go wrong.

EPDM comes in wide rolls, so a roof that would be a patchwork of small pieces in another material becomes a handful of large sheets. The fewer seams a flat roof has, the fewer chances it has to leak, and that is most of why EPDM lasts the way it does.

The attachment

Adhered, fastened, or ballasted to fit the deck.

We adhere the membrane to the deck, mechanically fasten it, or hold it down with ballast depending on the building, the slope, and the wind exposure. The right method is the one the roof actually calls for, and we tell you which that is before we order anything.

Honesty

EPDM is not the answer for every flat roof.

A black rubber roof absorbs heat, so where cooling load matters we may steer you to a reflective white membrane like TPO instead. And where a kitchen exhaust dumps grease, PVC is the better skin. We quote the membrane your roof needs, not the one we feel like selling.

Flat roof leaking, or just tired?

A project consultant walks the roof, checks the seams and the drains, and tells you whether EPDM is the right membrane or whether another single-ply fits your building better. The inspection is free, with a roof report.
