Skylight installation is a roofing job, not a window job. It requires cutting through your roof deck sheathing, framing a structural curb between the trusses or rafters, and building a weatherproof barrier with flashing, underlayment, and sealant. Iowa City Roofing & Maintenance has been installing skylights in Iowa City for 19 years โ every one leak-free.
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
Free on-site assessment. We check your roof structure, identify the optimal position between rafters, and present skylight options with honest pricing. Sun angle analysis included.
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 โ it's built to structural standards.
Weather Barrier
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 โ never behind them.
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.
