Flagstaff Roof Pros provides professional roof skylight installation in Flagstaff, AZ for residential and commercial properties across Coconino County and the Colorado Plateau. A skylight in Flagstaff needs to sit taller than the snow. That sounds obvious right up until you count how many deck-mounted units are set nearly flush in roofs that carry a foot of pack for months at a time.
The city's own code tells you what it thinks about accumulation. In its plumbing amendments Flagstaff raised the required height of a vent stack above the roof to twelve inches and struck out the alternative letting a stack stop six inches above anticipated snow. Given the choice between a fixed generous height and an estimate, the city took the fixed height. It is a useful signal for anything else that sticks up through a roof.
The same logic applies to glazing. A curb-mounted skylight on a properly built curb keeps the glass, the seal and the flashing above the pack. A deck-mounted unit sitting nearly flush spends the winter as a shallow basin with a warm bottom, melting the snow directly over it and refreezing that water at its cold edges. Height is the whole design question here, and it is settled at the framing stage rather than at the flashing stage.
The glass is rarely the culprit. What fails is the head flashing, the step flashing climbing the sides, and the seal where frame meets curb, three details sitting submerged and cycling for months on end. We build the curb, flash it as a stepped system with separate counterflashing rather than a bead of sealant, and run ice barrier across the whole area around it.
The second complaint arrives every February and it is not a leak at all. A skylight shaft is an uninsulated tube running from a warm room up to a cold roof. If the shaft walls are not insulated and air-sealed, water will run down the inside of a perfectly sound unit and you will blame the roof for it. Fixing the shaft is drywall and insulation work rather than roofing.
Sun tunnels are the honest downsell in this category and we point at them often. If what you want is daylight in a hallway or a bathroom rather than a view of the sky, a tube costs a fraction of a framed skylight, puts a much smaller hole in a roof that has to carry a load, and has far less flashing available to go wrong.
Our insured team brings the right materials and equipment to every job — Class A and Class B roof assembly listings, self-adhering polymer modified bitumen low-slope sheet, a sixty pound per square foot ground snow load adopted by ordinance, roof substrate replacement capped at ten percent of the deck, plumbing vent stacks terminated twelve inches above the covering, ice barrier underlayment carried past the interior wall line — and backs the work with a written workmanship warranty. We serve Flagstaff and nearby communities including Doney Park, Kachina Village, Timberline-Fernwood, Fort Valley.

Materials, equipment and how we do roof skylight installation
The difference between roof skylight installation that lasts and roof skylight installation that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with Class A and Class B roof assembly listings, self-adhering polymer modified bitumen low-slope sheet, a sixty pound per square foot ground snow load adopted by ordinance, roof substrate replacement capped at ten percent of the deck, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Flagstaff job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of roofing work in Coconino County and the Colorado Plateau means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Flagstaff Chooses Flagstaff Roof Pros
- ✓Every estimate cites the City of Flagstaff amendment it is built to, and the amended pages come stapled to it rather than quoted from memory.
- ✓We state a sheathing allowance in sheets and a price beyond it, because a roofing license stops at ten percent of the deck and yours may run past it.
- ✓We measure plumbing vent stack heights before chasing a winter leak, since the city requires twelve inches and a short stack explains a great many of them.
- ✓Anything laid between October and April is hand-sealed under every tab, to the manufacturer's cold-weather sheet, which we hand you with the invoice.
