Rubber roofing covers the flat and low-slope sections of a roof that shingles were never built to handle. We roll EPDM, TPO, or PVC membrane across the deck in wide sheets, fasten through the substrate, and seal every lap so water cannot wick.
Salt air and bay humidity attack fasteners and peel cheap patch coatings, so we spec waterproofing material that stays flexible through a Nor'easter and a July heat wave. A detailed membrane outlasts a tar-and-gravel built-up roof that cracks, blisters, and ponds.
On a 1950s ranch or Cape Cod cottage, we inspect the roof, tear off the old roofing felt and tar paper, and replace rotted plywood or OSB sheathing. Insulation and ventilation get checked while the deck is open, since trapped attic air rots framing.
- EPDM membrane is the standard rubber sheet for flat roofs, and it resists UV degradation and standing water better than most brush-applied coatings.
- TPO and PVC membrane are heat-welded at the seams, which fuses the sheets into one skin instead of trusting adhesive alone.
- Modified bitumen and built-up roof assemblies, often torch-applied, still suit older parapet walls, though salt air makes them brittle sooner.
- A self-adhered ice-and-water shield runs along the eave and valley before the membrane, stopping meltwater from backing up into an ice dam.
- Drip edge, rake trim, and coping get reset at the perimeter, because a loose edge is where wind uplift starts.
- Pipe flashing, vent boots, and skylight curbs get fresh boot flashing, counter-flashing, and sealant, since penetrations leak far more often than the field does.
- Chimney flashing and apron flashing get rebuilt with new mastic and roof cement where the masonry meets the roof.
- Steep gable and hip sections keep their asphalt shingles over synthetic underlayment, along with wood shake, cedar shake, slate, clay tile, or concrete tile, because rubber belongs on slopes under 3/12.
- Deck framing matters as much as the sheet, so a joist, ridge beam, or purlin showing decay gets sistered with new lumber first.
- Anchors, nails, screws, and fasteners get set flush and covered with caulk or adhesive, since one overdriven nail is a slow leak.
- Metal panel and corrugated panel roofs over porches, canopies, and deep overhangs get their fasteners and washers checked while we are up there.
- A vapor barrier and added insulation go in above the flat section, with a snow guard where the upper slope dumps onto it.
- Mansard, gambrel, and awning sections get battens, counterbatten details, and a metal verge so the transition to rubber sheds properly.
- Roofing square, nail gun, and air compressor stay within reach on every job, and we check fastening patterns against local building code before the final roof estimate.
