Gilroy Roof Pros provides professional roof coatings & sealing in Gilroy, CA for residential and commercial properties across the South Santa Clara Valley. A coating buys years on a roof that still has a sound substrate. It is not a way to fix a roof that has stopped working, and in this city it carries a wrinkle nobody mentions in the sales pitch: coatings weigh something, and weight is the constrained resource here.
A high-solids silicone applied at a serious mil thickness adds real pounds across the entire surface. On a low-slope section already carrying tapered insulation and a cover board, or on a roof sitting close to the 7.5-pound figure the City of Gilroy uses as its structural review trigger, that added load has to be counted rather than waved away. So we count it and show you the sum.
The hard refusal first. A coating over a tile field does nothing useful whatsoever. The waterproofing on a tile roof is the underlayment, which sits under the tile, and no amount of product applied on top of the tile ever reaches it. If somebody has offered to seal your tile roof to stop leaks, they are selling you a decorative finish at a waterproofing price.
The second refusal is nearly as common and more expensive. Coating over a saturated substrate seals the water in and destroys the deck faster than leaving it alone would have. We take moisture readings and, on larger commercial sections, core cuts before quoting a restoration. If the substrate is wet, the answer is tear-off, and we say so even though the coating is by far the easier sale.
Where a coating is right, it is genuinely good value. Sound single-ply or modified bitumen with plenty of life left in it, seams and penetrations detailed with reinforcing fabric first, primer matched to the substrate, and a silicone or acrylic system installed to the manufacturer's wet-mil schedule with the readings recorded. Done that way it keeps the existing membrane out of a landfill.
For commercial owners there is a compliance angle worth knowing about early. Recoating an existing non-residential low-slope roof at 2:12 or less falls under the 2025 California Energy Code cool-roof provisions, so the product's rated reflectance becomes a code question rather than just a heat question. We specify to that from the start and hand you the product listing along with the invoice at the end.
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 coatings & sealing
The difference between roof coatings & sealing that lasts and roof coatings & sealing 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.
