Garden Grove Roof Pros provides professional residential roof installation in Garden Grove, CA for residential and commercial properties across central Orange County. Garden Grove does not build many new houses. It builds additions, second units and garage conversions on lots that were finished in the 1950s and 1960s, and every one of those needs a roof that goes on where there was no roof before. That is this page.
Start with what the wildfire code does not do here. California's wildland-urban interface provisions, in their own code since the start of 2026, apply to a new building in a Fire Hazard Severity Zone or a State Responsibility Area.
Garden Grove is flat, fully built-out coastal-plain Orange County, and essentially none of it carries that designation. The statewide floor is a Class C covering, and the laminated shingles we install reach Class A in a listed assembly regardless.
So the value here is not the fire class. It is the trade stack. An ADU roof sits between a framing inspection and the stucco, the windows, the drywall and the array somebody wants on it later, and every one of those trades is waiting on a dry building.
We write the dry-in date into the scope and treat it as a deadline rather than an intention.
The order of inspections drives that date. The deck is nailed, the sheathing inspection happens before anything covers it, and only then does underlayment go down. On a detached second unit the new plane also has to tie into the existing house roof at a wall or a valley, and that intersection is where the next ten years of leaks are decided. It gets built from the wall outward with new metal, never with sealant.
On material, the ordinary answer is the right one. A fiberglass-mat architectural laminate over synthetic underlayment, with new valley metal, new pipe jacks and a starter course at the rake, matches what is already on the street and costs the least of anything we would stand behind. Tile looks correct on some of these blocks and loads a conversion roof nobody engineered for it.
Where we will talk you out of hiring us: if a general contractor is building your ADU turnkey and already has a roofer in the price, that roofer will dry the building in faster than we can get a separate crew to the same address. Call us when the roof is a standalone scope, or when the plans call for new sheathing over old framing.
Our insured team brings the right materials and equipment to every job — synthetic underlayment, SBS-modified bitumen cap sheet, 24-gauge standing seam panels, concrete S-tile profiles, Class A fire-rated assemblies, 60-mil TPO single-ply membrane — and backs the work with a written workmanship warranty. We serve Garden Grove and nearby communities including Westminster, Santa Ana, Anaheim, Stanton.

Materials, equipment and how we do residential roof installation
The difference between residential roof installation that lasts and residential 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 synthetic underlayment, SBS-modified bitumen cap sheet, 24-gauge standing seam panels, concrete S-tile profiles, 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 Garden Grove 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 central Orange County means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
