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. Marmaduke Roofing & Maintenance — leak-free skylight installation in Marmaduke.
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
Skylight Planning
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
Roof deck opening cut to exact dimensions. Structural curb built between rafters with doubled headers for load transfer. This is the foundation that holds the skylight and carries snow load — it's built to structural standards.
Flashing & Waterproofing
Full flashing system: ice-and-water shield base layer, step flashing and counter-flashing on all four sides, woven into the existing shingle field. Water flows over the flashing and onto the shingles below — never behind them.
Final Seal & Trim
Skylight unit set into the curb and flange sealed to the roof deck. Shingles re-laid around the unit with proper overlap. Inside, rigid insulation installed around the light shaft to prevent condensation. Interior trim finished. Watertight verified from the attic.
