Burrillville Commercial Roofing — Fully-Adhered EPDM Membrane Over a Low-Slope Rear Deck

Like most Pinnacle roofing projects, the work was completed efficiently — minimizing disruption for the property owner.

Pinnacle makes every project affordable with monthly financing options, including 0% interest for 18 months.

A commercial building on Victory Highway in Burrillville needed its low-slope rear deck re-covered, and Pinnacle handled it as a full commercial roofing project — stripping the tired flat section back to a sound substrate and rebuilding it as a modern EPDM membrane assembly built to shed water and take foot traffic for decades.

Scope of Work

The crew cleared the existing low-slope surface, inspected the deck, and worked in a logical order: a fastened cover board to create a clean, uniform base; a fully-adhered EPDM rubber membrane rolled out and bonded across the field; then careful seam and edge detailing so every lap and transition was sealed. Perimeter flashing and the roof edge were finished last, tying the membrane into the walls and terminations. See how we approach flat roofs on our commercial roofing page.

What We Installed (And Why)

This is a single-ply EPDM membrane system — the workhorse of low-slope commercial roofing. Over the prepared deck the crew fastened a cover board to smooth out the substrate, then fully adhered the EPDM sheet so the membrane bonds continuously rather than relying on loose ballast. The seams are the heart of a rubber roof, so each lap was detailed and sealed, and the parapet and edge flashings were wrapped to keep wind-driven water out of the terminations.

Because much of this job was documented during construction, the story here is really about the assembly rather than a glossy finished photo. A fully-adhered membrane resists wind uplift, handles the ponding and freeze-thaw cycles a flat New England roof sees, and gives the building owner a clean, monolithic surface that is straightforward to inspect and maintain. Every penetration and edge was flashed as its own detail, because on a low-slope roof the field rarely fails first — the details do.

Good To Know: How long does an EPDM commercial roof last?

A properly installed, fully-adhered EPDM membrane commonly delivers 25 to 30 years of service when the seams and flashings are detailed correctly and the roof gets occasional inspection. EPDM handles Rhode Island’s UV, temperature swings, and standing water well, and small membrane repairs are simple to make down the road — which is exactly why it remains the go-to choice for low-slope commercial decks like this one.

Why This Approach Works

Low-slope roofs cannot rely on gravity the way a steep shingle roof does, so the whole system has to be watertight on its own. A fastened cover board over the deck, a fully-adhered rubber membrane across the field, and hand-detailed seams and flashings give you a continuous, sealed surface with no shingle laps for water to work under. Fully adhering the sheet — rather than leaving it loose-laid or ballasted — also means the membrane can’t flutter or shift in high wind, which protects the seams over the long run. It is the right assembly for a flat rear deck that has to stay dry through years of rain, snow load, and standing water, and it gives the owner a roof that is easy to inspect and inexpensive to maintain.

Burrillville, RI

Burrillville is one of Rhode Island’s largest and most rural towns, a spread of villages, mills, and open land up in the northwest corner of the state. Its mix of older commercial buildings and working properties means plenty of low-slope roofs that need durable, no-nonsense membrane systems. Pinnacle is proud to serve business owners across Burrillville with commercial roofing built for the long haul.
