Roof repair in West Hills usually costs between $350 and $1,400 depending on what’s failing, with most standard repairs landing around $500 to $850. Leaks around flashing, cracked vent boots, and missing shingles are the calls we get most from homeowners in the 91307 and 91304 zip codes. We know these roofs.

Styles & brands we work with
Commercial Roof Repair in West Hills
Commercial roof repair in West Hills addresses flat and low-slope systems on retail storefronts along Sherman Way, office buildings near Fallbrook Center, and the smaller industrial spaces off Roscoe. These roofs take a beating from the Valley’s summer heat, which can run surface temperatures past 150 degrees, splitting seams and drying out membrane flashing faster than pitched residential roofs. The job usually involves patching TPO or modified bitumen membranes, resealing penetrations around HVAC units, and rebuilding pitch pans that have cracked from UV exposure.
Flat Roof Patching and Membrane Repair
A flat roof patch in West Hills typically runs $450 to $900 for a standard repair, depending on membrane type and damage spread. We clean the area, cut back the failed material, and weld or adhere a new patch that matches the existing system. When the membrane is too far gone, we’ll tell you straight and give you a price for a targeted replacement section rather than selling you a full tear-off you don’t need yet.
Seam and Penetration Sealing
Most commercial leaks we chase in West Hills aren’t from roof-wide failure. They’re from one penetration, one seam, or one edge detail that opened up. We reseal pipe boots, reflash curbs, and re-tape seams using manufacturer-specified materials. A seam repair usually lands between $350 and $700, and we photograph everything before and after so you can see exactly what was done.
Roof Leak Repair in West Hills
Roof leak repair in West Hills is the single most common call we take, and it’s rarely as simple as one missing shingle. The older ranch homes north of Roscoe, the split-levels off Saticoy, and the hillside properties off Bell Canyon all have their own failure patterns. Most leaks we find trace back to flashing, the metal strips that seal joints around chimneys, vents, and valleys. On a 1960s house, that original galvanized flashing is often corroded through or never was installed correctly to begin with.
Flashing and Valley Repair
When a West Hills roof leaks at a valley or chimney, we don’t caulk over it and hope. We pull the compromised flashing, inspect the decking underneath, and install new metal that’s actually lapped and fastened correctly. A flashing repair runs $400 to $950 depending on how much has to be removed and whether the surrounding shingles are reusable. The old ones usually aren’t on a house this age.
Vent Boot and Pipe Collar Replacement
Vent boot repair, the rubber collar around plumbing pipes that pokes through your roof, is one of the cheapest fixes we do and one of the most common sources of slow leaks in West Hills. The rubber cracks and shrinks after 10 to 15 years of Valley sun. This repair runs $250 to $450 when caught early. Left alone, the same leak rots decking and you’re suddenly looking at a $1,500 repair instead.
Trusted Brands We Service in West Hills
We install and repair shingle systems from Atlas, IKO, and Tamko, three manufacturers that build products suited to the San Fernando Valley’s heat and wind. Homeowners in West Hills often inherit whatever brand the last roofer used, so we stock matching materials locally and can usually match existing shingles for a patch without a full re-roof. If the original is discontinued, we’ll tell you before we quote, and give you options that don’t leave a visible mismatch on your roof line.

AfterCommon Roof Repair Problems We See in West Hills Homes
- Hidden wood shake layers under composition shingles. Many original 1960s tract homes north of Roscoe had a cheap comp shingle layered directly over the original shake, and tear-offs reveal double layers that need special disposal and added decking repair. If your home has had more than one re-roof, we check for this before quoting.
- Low-slope eave leaks on mid-century ranch designs. The original 1960s ranches were built with shallower pitches than modern code prefers, and architectural shingles installed without proper underlayment fail at valleys and penetrations. We use ice and water shield in these vulnerable zones.
- Fire zone material violations on hillside lots. West Hills sits in a High Fire Hazard Severity Zone, and L.A. County brush ordinances require Class A fire-rated materials on many brush-adjacent properties. We’ve seen stop-work orders issued because another roofer used non-rated materials on hillside lots near the open space north of Roscoe.
- Cracked and curled shingles from Valley heat. Summer temperatures in the western San Fernando Valley bake roof surfaces, and composition shingles that are 15 to 20 years old start shedding granules and curling at the edges. This is the early warning sign before leak damage begins.
Pricing for Roof Repair in West Hills, CA
Here’s what you can expect before you call. Shingle replacement in West Hills, a bundle or two of missing or broken shingles, runs $250 to $550. Vent boot and pipe collar replacement runs $250 to $450. Flashing repair around a chimney or valley runs $400 to $950. A flat roof patch on a low-slope residential roof runs $450 to $900. Decking repair, when rotted wood has to be cut out and replaced, adds $55 to $85 per sheet depending on thickness and access. A full tear-off on a mid-century ranch that reveals a hidden shake layer will change the quote, because that’s double disposal and added decking work. We’ll show you the price in writing before any work starts. Call (650) 456-5615 for a free estimate on your specific roof.

FAQs About Roof Repair in West Hills
You can sometimes tell from the underside, in the attic, by looking for gaps or uneven decking, but the reliable answer only shows up when the old shingles come off. Many original 1960s homes in the tract north of Roscoe had wood shake roofs that were later covered with composition shingles instead of being torn off. When we pull that top layer, we find the shake still there. That means double disposal fees and usually decking repair before the new system goes on. We price for the possibility in our written estimate so you’re not surprised mid-job. Call (650) 456-5615 and we’ll inspect yours before quoting.
L.A. County’s High Fire Hazard Severity Zone rules require Class A fire-rated roofing materials on many brush-adjacent lots, including much of the hillside terrain off Valley Circle and the open space north of Roscoe. That means the shingles, underlayment, and even the flashing details have to meet fire-resistance standards that a standard three-tab shingle won’t pass. We use Class A materials from Atlas, IKO, and Tamko on these properties and we know which West Hills lots trigger the requirement. The repair cost is sometimes higher because the material spec is higher. It’s worth getting right the first time, because a stop-work order costs more than the right shingle. Call (650) 456-5615 for a quote specific to your hillside lot.
We start by finding the actual leak source, which on a low-slope ranch is usually flashing, a valley, or a penetration, not the broad roof field. Our crew opened up a mid-century ranch in the original West Hills tract north of Roscoe and found two layers of old wood shake under failing composition shingles. We pulled the double layer, replaced rotted decking, and installed a new CertainTeed system with a full ice and water shield across the valleys to stop the recurring leak at the low-slope eave. On a repair, the approach is similar: isolate the failure, fix it with correct underlayment and flashing, and photograph everything. You don’t need a full re-roof just because one section failed. Call (650) 456-5615 for a straight answer on your roof.
Because on older West Hills homes, the wood under the shingles, the decking, is often the first thing that failed. A roof that leaked for years before you noticed has been quietly rotting the plywood or the original skip sheathing underneath. On a mid-century ranch, that decking is sometimes 60 years old and has never been inspected. When we open the roof and find soft wood, we cut it out and replace it, per sheet, at a price that’s on your written estimate before work starts. We don’t hide it, and we don’t lay new shingles over rotted wood and call it done. Call (650) 456-5615 and we’ll show you exactly what we found.
Architectural shingles are rated for higher wind speeds than standard three-tab, often 110 to 130 mph depending on the manufacturer, which is generally sufficient for the wind conditions we see in West Hills. The more important factor is the nailing pattern and underlayment. A shingle’s wind rating assumes proper installation, and we see too many roofs in the hills off Bell Canyon where the previous roofer skimped on nails or skipped the underlayment at the eaves. We install to manufacturer wind specs and we put ice and water shield at valleys and eaves. Call (650) 456-5615 if you’re seeing lifted shingles after the Santa Anas.
If your West Hills roof is leaking, missing shingles, or just showing its age, call (650) 456-5615. Dylan Pace will give you a written price, a real arrival time, and photo proof when the work is done. That’s how roof repair should work.
