Like most Pinnacle 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 Mawney Brook Road home in East Greenwich traded a flat, closed ceiling for a shaft of real sky. The owners wanted the dim upper level to feel bright without adding a single lamp, so Pinnacle set a deck-mounted skylight into a freshly finished asphalt roof and framed a clean interior light-well beneath it.

Scope of Work

The crew began by laying out the opening from inside, locating the rafters so the new curb landed cleanly between framing members and the interior daylight would fall where the owners wanted it. From the roof, we cut the deck to size, built up the mounting curb, and wrapped the entire opening with self-adhered ice-and-water membrane so the most vulnerable part of any skylight installation — the perimeter — is sealed against wind-driven rain and winter ice. The manufacturer flashing kit was then integrated course by course with the surrounding shingles: apron flashing at the base, step flashing up the sides, and a head flashing tucked under the upslope courses. Inside, the crew squared and finished the light-well so the daylight spreads evenly into the room rather than falling in a single harsh column, and cleaned the site so the only sign of the work was the new light overhead.

What We Installed (And Why)

The unit is a deck-mounted skylight seated on a proper curb and locked into a matched flashing kit rather than smeared in with caulk. That distinction matters: a skylight only leaks when water is allowed to sit against a seam, so the whole assembly is built to shed water the same way a well-flashed chimney does — in overlapping layers that each drain onto the one below. Around the opening, the ice-and-water wrap forms a continuous waterproof collar that backs up the metal flashing.

Because the surrounding field is architectural asphalt shingle, the skylight was woven into a roof designed to protect it for decades, not retrofitted into aging material that would need to come off again in a few years. The result is a fixture that looks like it was always part of the roof line and a ceiling that now reads as open and calm instead of boxed in.

Good To Know: Will a new skylight leak down the road?

A skylight installed correctly is no more likely to leak than any other roof penetration — the failures people remember almost always trace back to old units set in tar with no real flashing. The protection here comes from three overlapping layers: the ice-and-water membrane wrapped around the opening, the metal flashing kit integrated with the shingle courses, and the counter-flashing that directs runoff back onto the roof. Maintained sensibly, a properly flashed deck-mounted skylight stays watertight for the life of the roof it sits in.

Why This Approach Works

Natural overhead light changes a room in a way side windows cannot — it reaches deeper into the space and shifts through the day. But daylight is only worth adding if the opening never becomes a maintenance headache. By building a curb, wrapping the perimeter in waterproof membrane, and layering the flashing into the shingles, Pinnacle keeps the two goals from fighting each other: the room gets brighter and the roof stays sealed. Doing the work into a finished asphalt roof, rather than an old one, means the daylight arrives with a long protective life already built in above it.
