Thinking about adding a skylight? The biggest concern is always leaks. Here's why ours don't leak: we build a structural curb between the rafters, wrap it in ice-and-water shield, install step flashing on all four sides, and re-shingle around the unit with proper overlap. Then we verify the seal from inside the attic. Shrewsbury Roofing & Maintenance — leak-free skylight installation in Shrewsbury.
We install deck-mounted skylights and curb-mounted skylights. Deck-mounted units sit flush against the roof deck and work best for shingle roofs on standard pitch. Curb-mounted units sit on a raised frame and work on flat or low-slope roofs. Both types get the same flashing treatment: ice-and-water shield, step flashing, counter-flashing, and sealant at every transition.
Our Skylight Installation Process
Site Assessment
We assess your roof from above and inside the attic. We locate the trusses and rafters, check the roof deck sheathing condition, and identify the best skylight placement for natural light based on sun angle, room layout, and roof pitch.
Structural Prep
Precise opening cut through the roof deck. Structural curb framed between trusses with load-bearing headers. Every cut edge of the sheathing sealed. The curb is the structural foundation — we don't skimp on the framing.
Weather Barrier
Self-adhering ice-and-water shield on all curb faces. Step flashing along both sides lapped under each shingle course. Head flashing at the top, apron flashing at the bottom. Waterproof sealant at every overlap and transition. The flashing makes or breaks the installation.
Install & Insulate
Skylight seated, sealed, and integrated into the roofline. Interior light shaft insulated with rigid foam. Trim and drywall finished inside. Final inspection from the attic confirms zero gaps, zero daylight showing at flashing joints.
