Fast, Reliable Roof Replacement Across Walnut
Roof replacement in Walnut runs $12,000 to $34,000 for a typical two-story stucco home, with hillside properties along the San Jose Hills often landing at the upper end because wind-rated fastening and design review add real cost. We’re a roofing-only contractor based in Westminster, and our Roof Replacement team works the 91788, 91789, and 91795 zip codes every week. If you’re staring at lifted clay tiles after a Santa Ana event or sitting on a 35-year-old roof that’s past due, call (855) 382-0485 and we’ll give you a straight answer about what the job actually needs.

What separates us from the general contractors who “also do roofs” is simple: this is the only trade we practice. Walnut’s hillside tracts, age-specific tile profiles, and city review process demand a specialist who has seen these exact roofs fail in these exact ways. We have.
Why Select Roof Repair Is Walnut’s Preferred Roof Replacement Company
Walnut homeowners ask us to handle replacements because we know the city’s permitting and design-review rhythm well enough to file a complete submittal the first time. That matters. A rejected packet adds two to six weeks, and if your tear-off is already scheduled, you’re left with an open roof and winter rain coming. We don’t put our customers in that position.
Our work in neighborhoods like Snow Creek, Walnut Valley, and the hillside streets off Valley Blvd has taught us where the Santa Ana wind corridors hit hardest. Homes facing the open foothills near the SR-60 corridor take wind-driven tile and shingle damage that flatland houses simply don’t experience. We size every replacement for that exposure, not for a generic Southern California spec.
Led by Noel Carrasco, our crew works with seven major roofing manufacturers, including CertainTeed, Owens Corning, and Atlas, which means a material recommendation comes from your home’s actual conditions, not from whatever brand we happen to stock. That’s the whole point of calling us “Select.”
Styles & brands we work with






New Roof Installation in Walnut
New Roof Installation in Walnut typically runs $14,000 to $28,000 depending on the square footage, pitch, and whether the property sits on an exposed hillside lot. For homes in the Granite Boulders tract or along the base of the San Jose Hills, we build for 130-mph wind uplift, which means upgraded fastening patterns and, in some cases, a fully adhered underlayment. That’s not optional in those neighborhoods; it’s what keeps your roof on the house during the next Santa Ana event.
What the Job Involves
A full new roof on a Walnut home means tearing off the existing material down to the decking, replacing any deteriorated sheathing, laying a synthetic underlayment rated for our climate, and installing the new system with fasteners specific to the material and wind zone. Permits get pulled through the city, and if your home falls under hillside design review, we file that packet before the first tear-off date is set.
When Walnut Homeowners Pull the Trigger
Most new roof installations in Walnut happen when a roof has passed its serviceable life or when a Santa Ana storm has done enough structural damage that patching no longer makes sense. If your clay tile is cracking along the ridge or your shingles are shedding granules into the gutters on Snow Creek Drive, the smart move is a full replacement before the next winter rain exposes what’s underneath.
Reroofing in Walnut
Reroofing in Walnut typically runs $12,000 to $26,000, and it’s the route we recommend when the decking is sound and the existing roof structure can accept a second layer or a clean re-cover. For 1980s and 1990s tract homes across Walnut Valley, reroofing over an existing layer saves the cost and mess of a full tear-off, provided the underlying deck hasn’t rotted from years of cracked tile underlayment.
Tile Matching and Discontinued Profiles
The hard part with Walnut reroofing is matching the builder-grade clay tile profiles that went out of production decades ago. We source discontinued profiles from salvage lots and specialty suppliers, because a visible profile mismatch will fail final inspection and trigger HOA complaints. We’ve done this enough times to know which yards carry which profiles and which profiles simply aren’t available anymore.

When Reroofing Beats a Tear-Off
If your underlayment is intact and the existing tile or shingle layer is still structurally sound, reroofing gets you a new roof in fewer days and at a lower labor cost. The caveat in Walnut is the hillside wind exposure. We won’t reroof over a system that was under-built for wind uplift in the first place. When the original fastening isn’t up to current code, a reroof simply replicates the same vulnerability.
Trusted Brands We Service in Walnut
We install and maintain roofs from seven major manufacturers, and for Walnut homeowners we most often recommend CertainTeed architectural shingles for the flatland tracts, Owens Corning Duration for exposed hillside streets, and Atlas for re-cover projects where weight is a factor. Because we’re not tied to a single brand contract, we stock components and order materials from whichever manufacturer makes the right product for your home’s pitch, exposure, and HOA-approved material list. That’s the brand-agnostic model Noel Carrasco built the company on.

AfterCommon Roof Replacement Problems We See in Walnut Homes
- Wind-lifted clay tiles on hillside streets. The Santa Ana winds that funnel through the SR-60 corridor and up the San Jose Hills are the single biggest driver of replacement work we do in Granite Boulders and the surrounding tracts. Lifted tiles crack underlayment, and once water gets under the system, the decking rots fast.
- Discontinued 1980s tile profiles that can’t be matched. Walnut’s original builder-grade clay tiles haven’t been manufactured in decades. When a section needs replacement and no match exists, homeowners face either a visible patchwork roof or a full replacement we can actually match. We’re honest about which one makes sense before we start.
- Underlayment failure on aging two-story stucco homes. The dry heat and intense UV of San Gabriel Valley summers break down organic underlayment faster than most homeowners realize. By the time you see a leak, the underlayment has usually been failing for years, which is why we recommend an inspection after every major wind event.
- HOA and city design-review rejections on hillside re-roofs. Walnut’s view-preservation rules mean a re-roof in certain subdivisions can’t start until the HOA and city sign off on the material, color, and profile. We file the complete packet before scheduling, so the wait doesn’t leave your roof open to the elements.
Pricing for Roof Replacement in Walnut, CA
A standard architectural shingle roof replacement on a 2,000-square-foot Walnut home runs $13,000 to $19,000. Clay tile replacements start around $22,000 and can reach $34,000 on steep hillside lots where wind-rated fastening, full underlayment replacement, and heavier structural loading are required. Re-cover jobs fall between $12,000 and $17,000 when the decking is sound. Factors that move the number: roof pitch, number of valleys, chimney and skylight flashing count, decking replacement, and whether city design review applies.

FAQs About Roof Replacement in Walnut
Yes, homes in Walnut’s hillside subdivisions, including Granite Boulders and parts of Snow Creek, are subject to city design review and HOA approval before a roof replacement can begin. The review covers material type, color, and profile, and it typically adds two to six weeks to the calendar. We file the complete submittal packet for you before any tear-off is scheduled, so the wait doesn’t leave your roof exposed to winter rains. Call (855) 382-0485 and we’ll tell you whether your specific property triggers review.
Plan on two to six extra weeks, depending on the subdivision and whether the HOA committee meets monthly or more frequently. The biggest mistake we see is homeowners or contractors starting the tear-off before approval lands, which leaves the roof open mid-winter. We schedule around the review, not ahead of it. Call (855) 382-0485 for a timeline specific to your address.
Yes, in most cases. We source discontinued profiles from salvage lots and specialty tile suppliers across Southern California, and we can usually find a match that passes both city inspection and HOA review. When a profile is truly unavailable, we’ll tell you before you spend a dollar and walk you through the alternatives. Call (855) 382-0485 to set up an inspection.
Concrete and clay tile, architectural asphalt shingles from manufacturers like CertainTeed and Owens Corning, and in some flatland areas, standing seam metal. The exact allowances depend on your tract’s HOA covenants and whether city design review applies. We’ll look at your specific approval requirements and recommend materials that are both allowed and appropriate for your home’s wind exposure.
The first step is a full inspection to identify every lifted tile, cracked underlayment section, and fastener that has pulled loose. Then we replace the roof with a 130-mph wind-rated system, which means upgraded nail patterns, ridge-to-eave underlayment runs, and in some cases fully adhered membrane in the valleys. We also document all storm damage for insurance purposes, which helps if you’re pursuing a claim. Call (855) 382-0485 for a free estimate.
