Why Crestview Roofing Co Santa Clarita Is Chatsworth’s Preferred Roof Repair Company
Chatsworth is a different animal from the rest of the San Fernando Valley. Ranches built in the 1950s and 1970s sit on county land with septic systems, well setbacks, and horse-keeping overlays that flatland roofers never think about. We do. Dylan Pace built this company in 2000 on a simple idea: give homeowners the real picture before the first nail goes in. For Chatsworth, that means scoping the permit path, the equipment access, and the staging limits before we quote, not after we start tearing off.
Every repair carries the 365-Day Done Right Promise in writing. If a covered repair fails within a year, we come back and fix it at no charge. No negotiation, no runaround. We also send before-and-after photos and a digital invoice by text, per The Relay Standard, so you see exactly what we did and what you paid. The price on the page is the price on the invoice.
Residents across Chatsworth have learned that a live person answers our phones 24/7, not a voicemail tree. When you call at 9 p.m. because water is coming through a ceiling, you get a real human who can schedule a technician for the next morning.
Styles & brands we work with






Flat Roof Repair in Chatsworth
Flat Roof Repair in Chatsworth is our most common call for the older ranch stock east of Topanga Canyon Boulevard and throughout Lake Manor. These homes were built when tar-and-gravel was the standard, and after fifty years of hot summers, the gravel wears thin, the asphalt cracks, and water finds its way into the decking. Standard flat roof patches in Chatsworth run $500 – $1,200, while a full re-cover of a 1,200-square-foot residential flat roof with a modern membrane lands between $6,500 and $11,000.
Tar-and-Gravel Repair vs. Full Re-Cover
When we arrive at a 1960s Chatsworth ranch for a flat roof repair, we cut back the cracked membrane to find solid decking, then patch the area with compatible materials and reinforce the seams. If the gravel is saturated and the decking feels spongy, a patch won’t hold. That’s when we talk about a re-cover using a Class A TPO membrane from GAF, which handles Chatsworth’s UV exposure far better than the original built-up roof ever did.
Barn and Outbuilding Flat Roofs
On equestrian properties, flat roofs on barns, tack rooms, and accessory workshops often get ignored until a leak ruins hay or damages tooling. We repair these on their own scope, separate from the main house. A typical detached barn flat roof patch in Chatsworth costs $800 – $1,800, depending on decking condition and how much saturated gravel we have to remove before laying down new membrane.
Shingle Roof Repair in Chatsworth
Shingle Roof Repair in Chatsworth usually means addressing blow-offs, granule loss, and cracked tabs on composition shingle roofs that have baked under the valley sun for twenty-plus years. A standard shingle repair, replacing a few lifted or cracked tabs and resealing the surrounding area, runs $350 – $800. Valley repairs, where two roof planes meet and channel water, cost more, typically $900 – $1,500, because the flashing work is more involved and the valley is the most leak-prone point on the roof.
Santa Ana Wind and Ember Damage
When the Santa Anas blow through the Santa Susana Pass, they rip loose shingles and drive embers into roof-to-wall junctions. We see homes along Browns Canyon Road and up toward the mountains where one cracked tab becomes a three-foot section of missing shingles in a single afternoon. Our repair scope always includes checking the starter course and the ridge line, because wind damage rarely stops at the first visible lift.
Matching Older Shingle Colors
Chatsworth homes from the 1950s through the 1980s often have shingle colors that manufacturers discontinued. We stock a wide selection of GAF, CertainTeed, and Owens Corning colors at our Los Angeles supply hub, and we’ll bring physical samples to your home before we order, so you see the match in daylight, not in a warehouse photo.
Trusted Brands We Service in Chatsworth
We install and repair roofs using manufacturer-backed materials from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Chatsworth customers, that means we’re not limited to one supplier’s catalog. If your existing roof is a discontinued CertainTeed shake-look shingle or a GAF Timberline from a 1998 re-cover, we’ll find the closest available match and order it before we start. Our parts and materials are staged in Los Angeles, which cuts a full day off most supply runs up the 118. We don’t phone in material selection, and we never use off-brand substitutes without telling you first.

AfterCommon Roof Repair Problems We See in Chatsworth Homes
- Cracked tar-and-gravel seams on flat ranch roofs. Four decades of expansion and contraction in Chatsworth’s 100-degree summers splits the asphalt topcoat. Water creeps in, saturates the gravel, and rots decking from the inside. Patching the visible crack without checking decking moisture is how small repairs become full reroofs.
- Lifted and blown composition shingles after Santa Ana winds. The same gusts that rattle horse gates along Box Canyon tear shingles at the rake edge and ridge. Once the seal strip breaks, wind gets under the tab and peels it back. Repairs here need to include inspecting the entire windward plane, not just the one shingle the homeowner spotted in the driveway.
- Undocumented additions and outbuildings with failing roofs. Chatsworth’s ranch properties often have barns, workshops, or converted garages that were never permitted. When the roof leaks, the county inspector becomes part of the conversation. We scope these carefully so you know what the repair triggers and what it doesn’t before we pull a permit.
- Valley and flashing failures on hillside homes. Homes tucked into the slopes below the Santa Susana Mountains have steep valleys that concentrate water and wind-blown debris. Open valleys with worn metal or missing underlayment are the first place we look on any Chatsworth leak call, because they’re the first thing that fails.
Pricing for Roof Repair in Chatsworth, CA
Here’s what you should expect to pay for common Chatsworth roof repairs: shingle replacement, $350 – $800. Flat roof patch, $500 – $1,200. Flashing repair around a chimney or skylight, $400 – $950. Valley repair, $900 – $1,500. Vent boot or pipe collar replacement, $275 – $550. Full flat roof re-cover on a ranch home, $6,500 – $11,000 depending on square footage and decking condition. What moves the number? Rotted decking, saturated gravel on an old built-up roof, steep-slope staging, and long material hauls up Box Canyon or Browns Canyon. If you’re on a septic lot with a tight staging strip beside a horse paddock, that changes the labor. We account for it in the written quote, not in a change order later. Call (661) 219-7793 for a free estimate, and you’ll get a fixed price before any work starts.

FAQs About Roof Repair in Chatsworth
Equestrian zoning means your property is under county jurisdiction, not city, and that changes two things: permit requirements and work scheduling. We pull county permits where required, and we plan staging and tear-off around horse traffic, turnout schedules, and any non-combustible zones the county requires for ember-shedding roof systems. Your bid will reflect that coordination, not just the square footage. Call (661) 219-7793 and we’ll scope it in person before quoting.
Yes, we can combine the main house and the detached barn under a single county permit in most cases, as long as both structures are on the same parcel and we’re repairing rather than replacing entire roof systems. We’ll list each structure separately on the quote so you see exactly what each costs. Some older barns were never permitted at all, and we’ll tell you upfront what bringing one into compliance means before we touch it.
We stop, document the damage with photos, and give you a written change order for the additional decking replacement before we proceed. On Chatsworth hillside homes, rotted decking is common along the rake edge and around valleys where wind-driven rain concentrates. The cost per 4×8 sheet of plywood replaced runs $90 – $140 including labor and fasteners, and we don’t move forward until you approve the number in writing.
No. Ridge vents are for sloped roofs with a peak. Flat and low-slope roofs like the tar-and-gravel systems on older Chatsworth ranches need different ventilation, usually through intake soffit vents and exhaust vents placed near the top of the slope, or through mechanical ventilation if the attic is sealed. If we see a flat roof with trapped heat and moisture during a repair, we’ll recommend the right ventilation fix and show you photos of why it matters. Call (661) 219-7793 and we’ll take a look with you.
A typical Chatsworth ranch home with a composition shingle roof runs 22 – 30 squares, while a flat tar-and-gravel roof on the same footprint is usually 1,800 – 2,400 square feet, or 18 – 24 squares. A repair quote should identify the specific affected squares, not the whole roof, unless we’re proposing a full re-cover. We always list square count, material type, and labor line by line, so you’re not paying for roof area we never touched.
