A Greenville Rd home in North Smithfield wanted the kind of daylight only an overhead opening delivers — bright, natural, and reaching deep into a room that side windows had never quite lit. Pinnacle answered with a new deck-mounted skylight set into the asphalt roof and finished with the clean, layered flashing that keeps a skylight watertight.

Scope of Work

Work started inside, where the crew located the framing and laid out the opening so the finished skylight would sit true and the daylight would land where the owners wanted it. On the roof, we cut the deck cleanly and built up the mounting curb before doing the single most important step of any skylight installation: wrapping the entire opening in self-adhered ice-and-water membrane. That waterproof collar backs up everything above it. The matched flashing kit was then layered into the surrounding shingle courses — apron flashing at the base, step flashing along the sides, head flashing tucked beneath the upslope shingles — so water is shed in overlapping layers. Inside, the light-well was framed and finished to spread the daylight evenly across the room, and the crew cleaned the site so nothing was left behind but the new light overhead.

What We Installed (And Why)

The skylight is a deck-mounted unit set on a proper curb and sealed with a full manufacturer flashing kit rather than relying on sealant to do the heavy lifting. The reason is simple: skylights leak only when water is allowed to pool against a seam, so the assembly is built to keep water moving — down and off the roof — the same way a well-flashed chimney or wall does. The ice-and-water wrap around the opening forms a continuous membrane collar that protects the deck even in the rare event water gets past the metal.

Set into an asphalt shingle field and flashed with care, the finished skylight looks like an original part of the roof line rather than an addition. The homeowner gains a room transformed by natural light and a penetration engineered to stay dry through New England rain, wind, and winter ice — a detail built once and built to last.

Good To Know: What actually keeps a skylight from leaking?

It is not the sealant — it is the flashing and the membrane underneath it. A properly installed skylight relies on three cooperating layers: ice-and-water membrane wrapped fully around the opening, a metal flashing kit woven into the shingle courses, and head flashing tucked under the upslope shingles to direct runoff back onto the roof. Sealant is only a finishing touch. When those layers are built correctly, a deck-mounted skylight stays watertight for the life of the roof it sits in — the leaks people fear come from units set in tar with no real flashing at all.

Why This Approach Works

Overhead daylight reaches further into a room and shifts naturally through the day in a way no side window can match, but it is only worth adding if the opening never becomes a source of worry. By curbing the unit, wrapping the perimeter in waterproof membrane, and layering the flashing into the shingles, Pinnacle lets the room get brighter while the roof stays sealed. Building the skylight into a sound asphalt roof means the daylight arrives with a long protective life already established above it.
