60-Mil Fully-Adhered EPDM Over a Failing Membrane — Portsmouth, NH

A Fully-Adhered EPDM Rubber Roof in Portsmouth, NH

This Portsmouth, NH homeowner had an aging, failing low-slope roof and needed a durable replacement built for the long haul. Our team installed a fully-adhered 60-mil EPDM rubber roofing system — the right call for a flat or low-slope roof where standard shingles simply don't belong.

What We Did

• Removed the aging, failing membrane down to the deck
• Inspected and repaired the roof deck for a solid, dry foundation
• Installed a fully-adhered 60-mil EPDM rubber membrane
• Expertly sealed all seams and penetrations for a watertight finish
• Added new drip edge flashing for a clean, finished edge

Why EPDM for a Low-Slope Roof

Asphalt shingles rely on slope to shed water, so on a flat or low-slope roof they fail fast. A fully-adhered 60-mil EPDM membrane is bonded directly to the substrate, which makes it far more resistant to wind uplift and gives you one continuous waterproof surface. The thickness matters too — 60-mil stands up to foot traffic, weather, and UV better than thinner membranes, which is why we spec it for long-term residential performance.

Where Low-Slope Roofs Actually Leak

On a rubber roof, the seams and penetrations are everything — that's where a low-slope roof leaks if it's going to. We took the time to seal every seam and penetration properly and finished the edges with new drip edge, so this Portsmouth roof is a clean, continuous, watertight system rather than a patchwork.
