Gilroy Roof Pros provides professional residential roof installation in Gilroy, CA for residential and commercial properties across the South Santa Clara Valley. This is the roof that goes on when there is nothing to tear off: new construction, a custom build, an addition, a dormer, or a structure stripped to bare wood because the sheathing itself is the scope. In Gilroy the first question is not the shingle.
The city's Residential Hillside zone runs along the western and southwestern edges of Gilroy, and roofing material there has to carry a minimum Class A fire rating, with ember-resistant vents approved by the Fire Marshal potentially required alongside it. Outside that zone the statewide residential floor is a Class C covering. Same shingle aisle, two different specifications, and the difference is set by the address rather than by the bid.
Beyond the city limits the test changes again. California's wildland-urban interface requirements, moved into their own code effective January 1, 2026, follow the State Responsibility Area line as well as the hazard class, so a parcel rated only Moderate out toward the hills can still owe ignition-resistant construction. We look your address up before we specify anything, and we put the finding at the top of the written scope.
Class A on a new building is an assembly, not a label on a bundle. Solid decking goes down first, then the underlayment and deck named in the listing, then the covering, and the vents have to be listed products rather than whatever is on the truck.
Substituting any one layer breaks the rating, which is the quiet way a cheaper bid gets cheap. We name the listing on the estimate so you can look it up yourself.
Inspections run in a fixed order and they set your calendar. The deck is nailed and inspected before it is covered, the building permit is held in this company's name, and the current City of Gilroy business license has to be live before the Building Division will issue it. We would rather hold that paperwork than have a framing crew waiting on it.
The recommendation we give for free: on a new build whose builder already has a roofing crew scheduled, keep them, because they will dry the structure in sooner than a separately scheduled crew can. Where it is worth calling us instead is the hillside parcel, where the vent listings, the blocked tile ends and the assembly paperwork are the job, and getting them wrong is found at final inspection.
Our insured and bonded team brings the right materials and equipment to every job — assembly weight in pounds per square foot including sheathing, standard-weight concrete tile at nine to eleven pounds per square foot, stone-coated steel formed in a barrel profile, 7/16-inch Exposure 1 sheathing with edge blocking at the panel joints, 26-gauge galvanized wall and roof intersection flashing, net free ventilating area at a one-to-150 ratio — and backs the work with a written workmanship warranty. We serve Gilroy and nearby communities including Morgan Hill, San Martin, Hollister, San Juan Bautista.

Materials, equipment and how we do residential roof installation
The difference between residential roof installation that lasts and residential roof installation that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with assembly weight in pounds per square foot including sheathing, standard-weight concrete tile at nine to eleven pounds per square foot, stone-coated steel formed in a barrel profile, 7/16-inch Exposure 1 sheathing with edge blocking at the panel joints, 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 Gilroy 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 South Santa Clara Valley means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
