Pomona Roof Pros provides professional cool roof installation in Pomona, CA for residential and commercial properties across the Pomona Valley. A new house built next door to you in Pomona would not have to meet the reflectance requirement. Your reroof does. That inversion is the whole story on this page, and it is the reverse of what most owners expect.
Pomona is Climate Zone 9. The new-construction rows do not reach it. Section 150.1(c)11A writes the steep-slope requirement for Zones 10 through 15, and Section 150.1(c)11B writes the low-slope one for Zones 13 and 15 alone. Neither list contains a nine, so on a new build in this city the prescriptive figure is simply not written.
The alteration rows are drawn wider. Section 150.2(b)1Ii covers steep-slope reroofing in Zones 4 and 8 through 15, and Section 150.2(b)1Iii(a) covers low-slope reroofing in Zones 4 and 6 through 15. Nine falls inside both, which makes the rule on an existing Pomona roof the stricter of the two.
What those rows ask: a steep slope needs 0.20 three-year aged solar reflectance with 0.75 thermal emittance, or a Solar Reflectance Index of 16. A low slope needs 0.63 aged reflectance, the same emittance, or an index of 75. Aged, not initial, taken off the rating listing for the exact product and color rather than off a brochure.
Which is why the section number in a bid matters. A contractor telling you Pomona is exempt is usually quoting 150.1(c)11A, true and irrelevant, because nobody is building you a new house. Ask which section the reflectance line is being complied under. A quote that cannot name one is quoting from memory.
The steep-slope row does have written ways out, and one of them is local. In Zones 2, 4, 9, 10, 12 and 14 a house with no ducts in the attic counts. So does a ceiling insulated to R-38, or that same assembly at a U-factor of 0.025, or a radiant barrier that is not fixed over spaced sheathing, or continuous insulation of R-2 and better above the deck or below it.
We measure the attic before pricing a covering. A house already sitting at the insulation threshold may have a compliance path open to it that changes nothing about how the roof looks from the street, and that is a cheaper conversation than the one most bids open with.
Where we would talk you out of it: an unconditioned detached garage or a patio structure, where the number buys nothing you will feel. On the house, the proposal names the product, its aged figures and the code section, so nothing has to be argued at inspection.
Our insured and bonded team brings the right materials and equipment to every job — architectural laminated shingles with six-nail fastening, SBS polymer-modified asphalt shingles, 1x6 spaced sheathing overlaid with half-inch plywood, two-ply modified bitumen with a granulated cap sheet, salvaged mission and S-profile clay barrel tile, 24-gauge standing seam with concealed sliding clips — and backs the work with a written workmanship warranty. We serve Pomona and nearby communities including Claremont, La Verne, San Dimas, Diamond Bar.

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 architectural laminated shingles with six-nail fastening, SBS polymer-modified asphalt shingles, 1x6 spaced sheathing overlaid with half-inch plywood, two-ply modified bitumen with a granulated cap sheet, 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 Pomona 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 Pomona Valley means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
