Gilroy Roof Pros provides professional cool roof installation in Gilroy, CA for residential and commercial properties across the South Santa Clara Valley. Ask every bidder on your Gilroy reroof one question before anything else. Which row of the energy code table is my roof on. The answers will not match, and the mismatch tells you who has read it.
The table splits twice, which is where bidders get lost. Once between new construction and reroofing, and again between steep slope and low slope. Gilroy sits in California climate zone 4, and zone 4 lands inside some of those four boxes and outside others.
The two that reach you are the reroof rows. Section 150.2(b)1Ii covers steep-slope reroofing in zones 4 and 8 through 15, asking a three-year aged solar reflectance of 0.20 with thermal emittance of 0.75, or an SRI of 16. Section 150.2(b)1Iii(a) covers low slope in zones 4 and 6 through 15 at 0.63, 0.75, or an SRI of 75.
The one that does not reach you is new construction. Section 150.1(c)11A runs zones 10 through 15 on steep slope, and zone 4 is not in it. So a new house in Gilroy and a reroof in Gilroy are answering different questions, and a bidder reciting new-construction language has the wrong page open.
Second question. What may I do instead. The code accepts several substitutions for the steep-slope reflectance: at least R-38 of ceiling insulation, a ceiling assembly at a U-factor of 0.025 or lower, a qualifying attic radiant barrier where the sheathing is not spaced, R-2 or greater continuous insulation at the deck, or a house with no ducts in the attic, which is written for zone 4 among a short list of zones.
Third question. What does my roof weigh. Exception 3 releases a roof construction of at least 25 pounds per square foot from the reflectance and emittance minimums, which in a tile town decides plenty of jobs. We weigh the assembly rather than assuming a profile qualifies.
Fourth question. May I see the listing and the compliance form together. Rated products publish aged reflectance and emittance against the specific color, and the 2025 edition of the code has been in force since the first of January. A kitchen-table assurance is not either document.
Our C-39 and the city business license the Building Division wants before it issues your permit are both checkable, and so is everything above. A bidder who cannot answer four questions is pricing somebody else's roof.
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 cool roof installation
The difference between cool roof installation that lasts and cool 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.
