Vallejo Roof Pros provides professional skylights & roof windows in Vallejo, CA for residential and commercial properties across the North Bay. A skylight in a steep Vallejo roof is mostly a shaft job. The plane sits at ten or twelve in twelve, the ceiling below is plaster over a knee wall or a cathedral, and the light has to travel through framing nobody ever drew a hole into.
We build curb-mounted units on this stock rather than deck-mounted ones. A site-built two-by-six curb standing proud of the plane lets us run step flashing up both sides and tuck a head flashing under the course above, which is the only assembly that survives on a roof this steep with this much water crossing it. Deck-mounted units rely on a factory kit that assumes a simpler roof than this.
The shaft decides whether you like the result. A splayed shaft, wider at the ceiling than at the roof, throws two or three times the light of a straight box, and on a steep plane the splay is nearly free because the depth is already there. It has to be insulated and air-sealed at the ceiling plane, or it becomes a condensation channel with a view.
Placement gets negotiated against the geometry, not chosen from inside. We will not set a skylight in a valley's drainage path, above a dead valley, or within about eighteen inches of a hip or a dormer cheek, because there is no room for flashing to do its work. Sometimes the room you want lit and the plane that will accept a hole are not the same room, and a tubular unit through a rafter bay is the answer.
An old aluminum-framed skylight that is fogged and dripping is not necessarily leaking. Single-glazed units with no thermal break condense on their own inner face on a damp night, and the water on your sill came from inside the house. New glazing or a new unit fixes that. Re-flashing it does not, and we have watched people pay for the wrong one.
When we reroof a house with existing skylights we quote replacing them in the same breath. Flashing a twenty-year-old unit into a new roof gives you a twenty-five-year roof with a five-year hole in it, and doing that labor twice costs more than the unit. We would rather lose the skylight line than sell a new roof around an old hole. We quote the shaft and the unit separately, because one of them is carpentry.
Our licensed and insured team brings the right materials and equipment to every job — open W-valley metal, closed-cut valleys, step and counter flashing, kickout flashing, self-adhering underlayment membrane, one-by skip sheathing — and backs the work with a written workmanship warranty. We serve Vallejo and nearby communities including Benicia, American Canyon, Napa, Fairfield.

Materials, equipment and how we do skylights & roof windows
The difference between skylights & roof windows that lasts and skylights & roof windows that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with open W-valley metal, closed-cut valleys, step and counter flashing, kickout flashing, 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 Vallejo 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 the North Bay means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
