Vallejo Roof Pros provides professional commercial & multifamily roofing in Vallejo, CA for residential and commercial properties across the North Bay. Vallejo's commercial stock reads like its housing. Brick storefront blocks with low-slope roofs hidden behind parapets, plus larger industrial buildings with long spans. Both are old, and on both the parapet and the edge are where the money goes.
On a downtown block the roof is usually a built-up or modified-bitumen field draining to interior leaders through a parapet scupper, with a party wall on one or both sides. The failures are the base flashing at the parapet, the scupper sleeve, and the joint where your roof meets a neighbour's at a different height. We treat those three as the scope and the open field as secondary.
For re-covers we use TPO or modified bitumen depending on the deck and the traffic. Sixty-mil mechanically attached TPO over tapered polyisocyanurate is the standard answer on a wood or steel deck with room to build up. Two-ply modified is better where parapet height will not allow added thickness, or where hot work is workable and the detailing is heavy. Deck fastener pull-out testing decides which of the two it is.
Occupied buildings drive the sequencing more than the material does. Retail below means night and weekend work, staged tear-off in sections that can be made watertight the same day, and a plan for where adhesive fumes or torch smoke will go relative to a tenant's air intake. We write that into the schedule rather than discovering it on day two with an angry phone call.
Documentation matters more here than on houses. Our quotes start at the perimeter and work inward. Property managers get a roof plan with sections marked, warranty registration lodged with the manufacturer, and a maintenance schedule covering twice-yearly drain clearing and a spring inspection, because most single-ply warranties are void without evidence that somebody maintained the roof. Without that paperwork a twenty-year warranty turns into a twenty-year argument, and the building owner loses it.
A re-cover is the right call about half the time. Two existing membranes already in place, wet insulation showing on a moisture scan, or a deck that has been quietly leaking over one span for years, and the honest answer is a tear-off. We take core samples before we quote, so that conversation happens before contract rather than arriving as a change order in week two. That order is the reverse of most commercial quotes.
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 commercial & multifamily roofing
The difference between commercial & multifamily roofing that lasts and commercial & multifamily roofing 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.
