Gilroy Roof Pros provides professional roof replacement in Gilroy, CA for residential and commercial properties across the South Santa Clara Valley. Gilroy's reroof permit application asks something most homeowners never see coming. It wants the weight of the finished roof assembly per square foot, sheathing included. That single line shapes the whole job, and it is the first number we work out.
The threshold is 7.5 pounds per square foot. Above it, the Building Division wants framing and support information, and the City's own structural engineer reviews the work before a permit issues. Standard-weight concrete tile passes that number by itself, before anyone counts the plywood underneath it. That is not a technicality. It is the difference between an over-the-counter permit and a plan check that adds weeks.
This matters more here than almost anywhere in the county. The median house in Gilroy was built in 1990, against 1975 for Santa Clara County as a whole, and just under half of the city's housing units went up in 1990 or later. That is the concrete-tile tract era. Thousands of those roofs are now hitting the age where the underlayment beneath the tile gives out while the tile itself still looks new from the street.
So the replacement conversation we have is not about color. It is about whether the weight goes back on. We measure the existing assembly, count the layers, read the framing from the attic, and put an actual pounds-per-square-foot figure on the estimate for each option you are considering. You should be able to compare two bids on load, not just on price, and almost nobody gives you that.
Where the framing is generous and the tile is sound, lifting and relaying over fresh underlayment is often the cheapest correct answer, and we will say so plainly. Where the framing is marginal, or the house has already carried an overlay, we show what an architectural shingle or a stone-coated steel assembly does to the number, and let you decide with the arithmetic in front of you rather than a sales pitch.
The build itself runs to the city's sequence. Tear-off, then the pre-inspection at code 235, sheathing nailing at 240 if we are re-decking, and the final at 935 with the smoke and carbon monoxide alarms verified. Manufacturer installation instructions stay on site for the inspector to read. You get the signed card at the end, not a promise that one exists somewhere.
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 roof replacement
The difference between roof replacement that lasts and roof replacement 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.
