AfterFast, Reliable Roofing Across Simi Valley
Roof replacement in Simi Valley typically runs $8,000-$20,000, while roof repairs average $400-$1,800, and tile roof repair lands between $600-$2,500. Most Simi Valley homes were built between 1963 and 1985, which means thousands of original composition shingle roofs are now past their useful life. Barrett & Sons Construction has been answering the phone since 1998, and Tom Barrett still picks it up himself. If your roof is leaking, granule-bald, or failing a WUI inspection, call (877) 610-1318 for a free estimate. We’ll come out, walk the roof with you, and put the scope in writing before any work starts.
Why Barrett & Sons Construction Is Simi Valley’s Preferred Roofing Company
Simi Valley homeowners don’t need another national outfit that quotes one price over the phone and shows up with a different number. They need a company whose owner lives close enough to drive by the job on a Saturday and see it with his own eyes. That’s how we’ve worked since 1998. Tom Barrett’s name, address, and license number are published and verifiable. Ask anyone on your street, or look up the license number yourself. We’re the crew the neighbors wave to, not a van you’ll never see again.
Our Roofing team works the full span of Simi Valley, from the 93063 ZIP on the east end to Wood Ranch and the ridgeline neighborhoods above the 118 in 93065. We know the Larwin tract homes, the stucco-over-wood-frame construction, the original composition shingles that should have been replaced a decade ago. We also know the fire-hardening code requirements that apply here and not across the hill. That local knowledge saves our customers money and keeps inspections moving.
Every roof we touch is backed by the written 90-Day Done Right Promise. If it’s not done right, Tom Barrett comes back and makes it right. One call. No runaround. And every price change, every allowance, every scope adjustment arrives as a written change order before a single nail moves. An allowance that isn’t on paper is a surprise waiting for a date.
Our Roofing Services in Simi Valley
Roof Replacement & Installation
Most Simi Valley homes built in the 1960s through the 1980s are due for their second or third roof. The original composition shingles installed during the valley’s rapid build-out have been baked by summer highs that regularly exceed 100°F and scoured by some of the strongest Santa Ana winds in the LA metro. A full roof replacement in Simi Valley runs $8,000-$20,000 depending on square footage, pitch, decking condition, and WUI requirements. We install Class A fire-rated systems that pass Chapter 7A inspection the first time.
Roof Repair
Not every roof needs to come off. A roof repair in Simi Valley typically costs $400-$1,800. We replace damaged ridge shingles, failed flashing, cracked tile, and worn pipe boots. If Santa Ana winds lifted a corner flashing on your Wood Ranch home, we’ll reflashed it correctly, not just nail it back down and hope. The permit inspector works for you, not for me. That’s why we like him.
Tile Roofing
Simi Valley has a high concentration of concrete and clay tile roofs, particularly in the newer subdivisions and custom hillside lots. Tile is durable, but underlayment fails, tiles crack from falling branches and foot traffic, and tile roof repair on Simi Valley homes typically runs $600-$2,500. We match existing barrel tile profiles and color, and we inspect the underlayment every time. Replacing a few cracked tiles without checking what’s underneath is how a $600 repair becomes a $12,000 water damage claim.
Metal Roofing & Specialty Systems
Standing seam metal roofs are growing in popularity across Simi Valley, partly because they carry Class A fire ratings and partly because they shed embers far better than asphalt shingles. A metal roof installation runs $15,000-$40,000 depending on gauge, coating system, and whether you’re in a mapped fire hazard zone. We also handle specialty roofing: low-slope systems, standing seam, and custom flashing details on hillside homes where wind and ember exposure are worst. If you’re considering metal for a Chapter 7A property, we’ll spec the assembly to meet code without overselling you on features you don’t need.

Trusted Brands We Service in Simi Valley
We install and service roofing and exterior products from brands you can look up, not mystery materials off a van. For windows and doors that often pair with a reroof, we carry premium lines including PGT, CGI, and Simonton. On the roof itself, we work with GAF and CertainTeed systems, installed to manufacturer spec so the warranty stands up. We keep the parts and materials Simi Valley homes actually need in local supply, which means fewer delays when we find a failed underlayment or a short sheathing run mid-job.
Common Roofing Problems We See in Simi Valley Homes
- Granule-bald composition shingles. The valley’s thermal trapping bakes original 1970s and 1980s shingle roofs until the granules are gone and the fiberglass mat is exposed. You’ll see granules in the gutters and bald patches from the street. At that point, leaks are not far behind.
- Santa Ana wind damage on ridgelines. Homes in Wood Ranch and the Knolls above the 118 take direct hits from wind events that lift ridge shingles and tear corner flashing. The damage often goes unnoticed until a ceiling stain appears months later.
- WUI inspection failures. Homes inside mapped fire hazard zones must have ember-resistant attic vents and proper drip-edge flashing. We regularly see homes that fail inspection because a previous contractor installed standard vents. It’s a cheap fix when caught early, but it means a full reroof if the inspector flags it mid-project.
- Dry rot from failed flashing. On raised-foundation and slab-on-grade homes across 93063, chimney chase flashing and valley flashing installed in the 1970s has long since failed. Water creeps in, rot spreads through the decking, and by the time you see it inside, the repair is structural.

FAQs - Roofing in Simi Valley
If your home sits within a mapped High or Very High Fire Hazard Severity Zone, any roof repair that touches the roof assembly may trigger Chapter 7A requirements, even for partial work. The rule of thumb: if you’re replacing sheathing, adding vents, or changing the roof covering, the ember-resistance and fire-rating standards apply. A patch job replacing a few shingles usually stays outside the requirement, but the best move is to confirm with your local building department before work starts. We handle the code check as part of every estimate. Call (877) 610-1318 and we’ll tell you exactly where your parcel stands.
Twice a year, and after every major Santa Ana event. The winds that come through Simi Valley are among the strongest in greater LA, and they lift ridge shingles, tear flashing, and drive debris into valleys. A post-wind inspection catches damage before the next rain turns it into an interior leak. We’ll do the inspection as part of a free estimate, no charge for the roof walk.
In the 93063 ZIP on Simi Valley’s east end, we see three problems over and over: granule-bald original composition shingles, failed chimney chase flashing, and dry rot in the decking where water has been seeping for years. Many of these Larwin-era homes also have cracked stucco and slab movement, but on the roof specifically, the original underlayment is almost always past its service life. If you have a 1970s tract home that hasn’t been reroofed since the Clinton administration, plan for a full replacement, not a patch. Call (877) 610-1318 for a free roof assessment.
It depends on the HOA’s architectural guidelines, and some newer Simi Valley developments have specific restrictions on roof materials and color. That said, many HOAs now allow standing seam metal because it carries a Class A fire rating and meets Chapter 7A requirements. We’ve installed metal roofs in HOA communities across Simi Valley, and we’ll help you review the architectural submission before you spend money on materials. The key is getting the HOA’s written approval first. We can help with the paperwork.
Yes, and it’s a smart requirement. Simi Valley’s building department will want to see that the roof can support the panel load and that the roofing assembly still has serviceable life left. Installing solar on a granule-bald 1980s shingle roof is a waste of money, because you’ll pay to remove and reinstall the panels when the roof fails. We recommend a roof inspection before any solar contract is signed. If replacement is needed, we’ll coordinate the reroof so the solar company can mount on a fresh, WUI-compliant system.
One Local Insight: WUI Fire Standards and Your Simi Valley Roof
Because most Simi Valley parcels sit within California’s High or Very High Fire Hazard Severity Zones, virtually every roof replacement or repair on hillside-adjacent tracts must comply with Chapter 7A WUI fire-hardening standards for roofing assemblies and ember-resistant vents. This requirement doesn’t apply across the hill in the San Fernando Valley’s LA County jurisdiction. What that means for you: if you’re in the mapped zone, your reroof needs a Class A fire-rated covering, WUI-compliant vents, and proper drip-edge detailing. A contractor who doesn’t know this will get you red-tagged at inspection and then bill you to fix it. We’ve been pulling permits and passing WUI inspections in Simi Valley for years. The inspector works for you, not for me. That’s how it should be.
What We Found on a 1978 Larwin Tract Home in the Knolls
On a 1978 Larwin tract home in the Knolls above the 118, our crew found the original composition shingle roof had become brittle from decades of Santa Ana wind events and 100°F summer heat. During tear-off, we discovered the plywood decking on the west-facing slope had dry rot from failed flashing at the chimney chase. We replaced the sheathing, installed a Class A fire-rated asphalt shingle system with WUI-compliant ember-resistant vents, and reflashed all penetrations before the inspector sign-off. That house passed inspection the first time. The homeowner had been told by another company that the roof just needed a patch. It didn’t.
