We’re Roof Installation specialists who know what 1950s and 60s tract homes in Canoga Park actually look like under the surface. Three layers of brittle composition shingles. Original 1×6 decking with dry rot at the valleys. Rubber pipe boots cracked from 110-degree summers. None of that surprises us. What might surprise you is how much of it is fixable with the right plan and a roofer who tells you the truth before the dumpster arrives.
Why Crestview Roofing Co Woodland Hills Is Canoga Park’s Preferred Roof Installation Company
We’ve spent 25 years taking roofs apart in this exact housing stock. The post-war stucco ranches off Sherman Way, the gable-roofed traditional homes near the 91303 and 91304 zip codes, the condos and townhomes that replaced older lots in the 1980s. Every one of them has a history. We know what the original builders used, what previous roofers patched over, and what the city now requires when you pull a permit for new work.
Crestview Roofing Co Woodland Hills operates on The Relay Visibility Guarantee. A written price before any work begins. Live trackable arrival time on the day of your install, so you’re not staring out the window wondering when we’ll show up.

That’s the Relay Standard, and it applies to every Roof Installation in Canoga Park job we take on.
The 365-Day Done Right Promise comes with every installation. If any part of the install fails within a full year, we come back and fix it at no charge. Not pro-rated. Not “that’s normal wear.” We make it right, in writing, included with the job.
Styles & brands we work with
Roof Flashing Installation in Canoga Park
Roof Flashing Installation in Canoga Park is the difference between a roof that leaks at year three and one that stays dry for 20. Flashing is the metal strips that seal the joints where your roof meets a chimney, a wall, a vent pipe, or a valley. When it fails, water gets under the shingles and rots the decking, and Canoga Park’s winter rains will find that failure fast. New flashing installation typically runs $400 to $1,100 depending on how many penetrations your roof has and whether the old flashing pulled away cleanly or left rusted fasteners behind.
Chimney and Valley Flashing
On the 1950s ranches near Topanga Canyon Boulevard, chimney flashing is often the first thing to go. Original builders used thin galvanized metal that eventually separates from the masonry. We replace it with step flashing tucked into the brick and sealed with roof cement rated for the valley’s heat. Valley flashing gets the same treatment: new metal, proper overlap, no shortcuts.
Pipe Boot and Vent Flashing
Rubber pipe boots on plumbing stacks crack fast in Canoga Park. The rubber dries out, splits, and water runs straight down the pipe into your ceiling. We replace them with boots designed for high UV exposure, and we check the surrounding shingles for granule loss at the same time.
TPO Roofing Installation in Canoga Park
TPO Roofing Installation in Canoga Park is the workhorse for flat and low-slope sections of a home, especially the add-ons and patios common on mid-century ranches. TPO is a white thermoplastic membrane that reflects heat instead of absorbing it. For Canoga Park’s 100-degree summers, that means lower attic temperatures and lower cooling bills. A typical TPO installation on a 400 to 800 square foot low-slope roof runs $4,500 to $7,800.
When TPO Makes Sense
If your home has a flat garage roof, a porch overhang, or a rambling single-story addition with a shallow pitch, TPO is often the right call. It welds together at the seams with heat, so there are no nail holes to leak. The white surface also keeps the roof decking cooler, which slows the aging of the wood underneath.
TPO and Cool Roof Rules
Los Angeles’s cool roof requirements favor TPO because it meets solar reflectivity standards straight out of the box. White TPO gives you a compliant surface without hunting for special shingle colors. We apply it with proper insulation and edge detailing so the Canoga Park heat doesn’t curl the seams.
Trusted Brands We Service in Canoga Park
We install and service materials from IKO, Atlas, and Tamko, which gives our Canoga Park customers access to architectural shingle lines rated for high solar reflectivity without a special order. Atlas Pinnacle and Tamko Heritage both carry cool-roof-rated colorways that pass the Los Angeles ordinance. Stocking these locally means we aren’t telling you the shingle color is on backorder for six weeks. We pull what the job needs, stage it at your home, and get moving. And of course, we still install GAF Timberline HDZ when the project calls for a heavier, high-wind shingle.

AfterCommon Roof Installation Problems We See in Canoga Park Homes
- Multiple layers of old shingles. Many roofs in the older neighborhoods off Roscoe Boulevard and Saticoy Street still have two or three layers because previous owners deferred tear-offs. Those layers trap heat against the decking and hide dry rot until a full re-roof exposes it.
- Dry-rotted decking at the valleys and chimneys. Water follows the valley line, and when flashing fails at a chimney penetration, the 1×6 decking underneath stays damp and rots. Opening up a 60-year-old Canoga Park roof regularly turns up soft spots that never showed on the surface.
- Cracked rubber pipe boots. The plumbing vent boots on nearly every older home we see in Canoga Park are brittle from UV exposure. They split, water gets past them, and the leak shows up as a ceiling stain nowhere near the pipe.
- Wood shake roofs covered with asphalt shingles. Some original Canoga Park homes were built with wood shake, then covered over with composition shingles decades later. Those roofs often lack the decking gaps needed for thermal expansion, so summer heat causes splitting and buckling that no surface patch can fix.
Pricing for Roof Installation in Canoga Park, CA
A full tear-off and re-roof on a standard Canoga Park ranch runs $8,500 to $13,500, using architectural shingles. Larger homes or those with steep gables run $13,000 to $16,000. If your roof has multiple layers, budget an extra $2,000 to $3,500 for tear-off labor, hauling, and dump fees. TPO on low-slope sections adds $4,500 to $7,800 depending on square footage. Flashing work is usually $400 to $1,100 per job.

FAQs About Roof Installation in Canoga Park
Yes, Los Angeles’s cool roof ordinance applies to new roof installations in Canoga Park and requires a minimum solar reflectance value, which most standard dark shingles don’t meet. The practical answer is you’ll be selecting from cool-roof-rated colors, usually lighter tans, grays, or whites. We’ll show you which Atlas, IKO, and Tamko lines carry compliant colors so your permit passes the first time. Call (650) 456-5615 and we’ll bring samples.
Code allows a maximum of two layers in most Los Angeles residential zones, but we almost never recommend layering over old shingles on Canoga Park’s 1950s and 60s homes. Multiple layers trap valley heat against the decking, accelerate granule loss, and hide rot that will fail within a few years. A full tear-off is the right move, and our estimates include it by default. Call (650) 456-5615 for a written tear-off and re-roof price.
We check the decking for dry rot, especially at valleys where the old flashing failed, and around chimneys where water migrated under the surface. We also look at rafter tails and fascia boards for termite damage, which is common in Canoga Park’s older wood framing. And we inspect all plumbing and vent penetrations to determine whether the boots and collars need full replacement, which they usually do. Everything we find gets documented in before photos and priced in writing before we proceed.
Plumbing vent boots fail more often than anything else we see on Canoga Park roofs. The rubber collar that seals around the pipe dries out and cracks from sustained 100-degree-plus temperatures and high UV exposure, letting water follow the pipe into the attic. Chimney and furnace flue flashing is the second most common failure, especially on homes built before modern step flashing became standard. Call (650) 456-5615 for an inspection and written fix list.
Because ridge vent runs the entire length of the roof peak and moves hot air out continuously, which matters when summer attic temperatures in Canoga Park regularly top 140 degrees. Box vents only exhaust air from isolated points, leaving pockets of heat that bake the underside of shingles and speed up granule loss. On a new roof installation, ridge vent costs a little more upfront but extends the life of the shingles noticeably.
