Gilroy Roof Pros provides professional asphalt shingle roofs in Gilroy, CA for residential and commercial properties across the South Santa Clara Valley. In most cities architectural shingle is the default because it is cheap. In Gilroy it is often the correct engineering answer as well, and that is a very different argument to make. A laminated shingle assembly runs roughly two and a half to three pounds per square foot.
Add 7/16-inch sheathing and synthetic underlayment and you are still comfortably under the city's 7.5-pound trigger. That means an over-the-counter permit, no structural calculations, no waiting on the City's engineer, and a meaningful reduction in the load your framing carries at the highest point of the house. On a tile-to-shingle conversion the weight reduction is not a rounding error, it is tons.
We are not going to pretend the trade is free. You lose the tile look, and on a street where every other house is barrel profile that is a genuine consideration rather than a snobbish one. You also give up some of the thermal buffer that an air-spaced tile field provides in a valley that runs hot through July. Ask us about the stone-coated steel option before you decide either way, because it splits the difference neatly.
Where we do install shingle, the specification is not the builder-grade version your tract originally got. Laminated shingles rated to ASTM D7158 Class H, six nails per shingle placed inside the reinforced nailing strip, factory-sealed starter at eaves and rakes rather than an inverted field course, and self-adhered membrane at valleys, at every penetration and at the low-slope transitions.
Slope drives the underlayment and this is where corners get cut. Between 2:12 and 4:12 the city and the code both require two layers, starting with a 19-inch strip parallel to the eave, then 36-inch sheets lapped 19 inches. Plenty of Gilroy tract houses have a low porch or a patio return sitting in exactly that band, and it is the first place a cut-rate crew skips a step.
If your house falls in the Residential Hillside zone the covering has to carry a Class A rating, and most modern laminated products get there as part of a listed assembly rather than on their own. We specify the assembly and hand you the listing, because the rating belongs to the whole build-up and not to the shingle considered in isolation.
Our licensed and insured 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 asphalt shingle roofs
The difference between asphalt shingle roofs that lasts and asphalt shingle roofs 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.
