Why Crestview Roofing Co Woodland Hills Is Winnetka’s Preferred Roof Installation Company
Winnetka homeowners call us because we put every number in writing before the first nail goes down. That’s not a slogan. It’s the Relay Visibility Guarantee, and it means the price on your written estimate is the price on your invoice, period. Dylan Pace leads our crews, and he’s the one who shows up to walk the roofline with you, not a sales rep reading from a tablet. The team works in uniform, background-checked, and you get a live arrival time you can track, so you know exactly who’s pulling up and when.
We know the houses here. The 1963 ranch near the Orange Line with a gable main roof and a flat garage roof. The 1987 two-story stucco on the west side with tile that’s starting to spall. The 1955 original composition shingle that’s baked past its service life. That local knowledge means we quote the right system for the right roof section, not a generic package. And our 365-Day Done Right Promise covers every repair we make for a full year in writing, included at no extra cost.

Tile Roof in Winnetka
Tile Roof installation in Winnetka typically runs $14,500 to $28,000 for a full replacement on a standard ranch or stucco two-story, depending on whether you go with lightweight concrete tile or full-weight clay. Most Winnetka homes that have tile were built with it in the 1980s and 90s, and those original tiles are now hitting the end of their 30 to 40 year underlayment life, even if the tile itself still looks fine. The real cost driver is what’s under the tile, not the tile itself, and that’s where cheaper quotes fall apart.
Underlayment and Batten Work
The underlayment on a tile roof is what actually keeps water out. On Winnetka homes where the original felt has dried and cracked from decades of Valley heat, we strip to the deck, install a high-temperature self-adhered underlayment at eaves and valleys, and run new battens before resetting or replacing tile. That’s the difference between a roof that lasts 40 years and one that leaks in five.
Tile Replacement Without Full Re-Roof
If your tile roof is leaking in one spot and the underlayment is still sound, we can match and replace broken or spalled tiles without tearing off the whole field. On a 1989 Winnetka two-story, we recently matched discontinued Monier tiles from a local salvage yard and replaced 14 broken pieces in about three hours. Written price first, photos before and after, digital invoice sent by text.
Roof Ventilation in Winnetka
Roof Ventilation work in Winnetka involves installing or retrofitting intake and exhaust vents so your attic doesn’t cook in July. Most 1950s and 60s ranch homes here were built with gable vents only, which doesn’t move enough air once you add insulation or switch to architectural shingles. We see attic temperatures hit 140°F in Winnetka summers, and that heat radiates down through the ceiling joists for hours after sundown. A properly vented roof changes that.
Intake and Exhaust Retrofits
The fix is balanced airflow: intake at the soffits or eaves, exhaust at the ridge or upper gable. On a 1962 ranch north of Sherman Way, we added continuous soffit vents and a ridge vent to a roof that had neither, and the homeowner’s cooling bill dropped noticeably the same summer. We calculate the vent ratio per square foot of attic floor, and the math goes in your written quote.
Ventilation on Flat Roof Sections
Flat or low-slope roofs over Winnetka garages and additions can’t use ridge vents, so we vent the attic below through the side walls or install mushroom vents if there’s a parapet. The goal is the same: get hot air out so the roofing membrane doesn’t bake from underneath. We’ll tell you honestly whether your low-slope section even needs ventilation, because not every flat roof does.
Trusted Brands We Service in Winnetka
We install and repair roofing with materials from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, and we’ll match whatever brand is already on your Winnetka roof when we’re doing a repair. For full replacements on ranch homes, we often spec GAF Timberline HDZ architectural shingles with a six-nail high-wind pattern. For flat or low-slope sections, we typically quote fully adhered TPO from GAF or CertainTeed. The brand goes in your written quote, along with the specific product line and the wind rating. No vague “premium shingle” language.

AfterCommon Roof Installation Problems We See in Winnetka Homes
- Santa Ana wind blow-offs at rake edges. The gusts that whip down through the Valley in October and November lift shingles that were nailed too high or with too few nails. We see this most on cheaper architectural shingle installs where the contractor skipped the extra nail pattern at edges and corners.
- Parapet wall flashing failures on flat garage roofs. Torch-down roofs on 1950s and 60s additions leak where the membrane meets the stucco parapet. The original contractor often skipped the reglet counterflashing, which is the metal strip cut into the wall that keeps water from running behind the membrane.
- No ice and water shield at eaves and valleys. On homes near the Orange Line where original wood shake was replaced in the early 2000s, installers frequently omitted high-temperature ice and water shield at the roof’s most vulnerable points. Those valleys and eaves are now the first places we see water staining.
- Ponding on low-slope roofs. Flat roofs over Winnetka garages and additions were often built with inadequate slope, so winter rain pools and sits. Proper drainage detail, usually tapered insulation under a new membrane, is the fix. A patch job won’t move the water off.
Pricing for Roof Installation in Winnetka, CA
A full composition shingle replacement on a typical Winnetka ranch runs $9,800 to $14,500. Add a flat roof over the garage or a converted addition, and you’re looking at another $3,200 to $6,800 for torch-down or TPO with proper drainage. Tile roofs land between $14,500 and $28,000. What moves the number? Tear-off layers, deck repair, whether the flat section needs new tapered insulation, and which wind rating your roof is engineered to meet. We give you a written line-item quote with all of that broken out before you sign anything. Call (650) 456-5615 for your free estimate.

FAQs About Roof Installation in Winnetka
Winnetka falls under Los Angeles County’s wind design requirements, and for most single-family homes, shingles must be installed to meet at least a 110 mph wind rating using a six-nail pattern at edges and corners. Some hillside or ridge-adjacent properties may need 120 mph details. A compliant quote from us lists the exact product and nailing pattern on the written estimate, so you can hand it to your insurance agent as documentation. Call (650) 456-5615 and we’ll tell you what your specific roof needs.
Yes. In Winnetka, flat and low-slope roof sections on garages or additions require their own permit documentation, separate from the main house roof. The city inspector verifies the underlayment, drainage slope, and drip edge before the deck is closed. We pull all permits for the job and walk the inspection with the inspector. It’s included in your written quote, not billed as a surprise line item later.
Your underlayment is compliant when we can show you a photo of the fully installed underlayment and drip edge before any shingles are nailed down. That’s the Relay Standard: before-and-after photo documentation at every inspection-critical stage. On a recent Winnetka job, the city inspector verified the underlayment and drip edge on a 1963 ranch, and the homeowner kept those photos for their insurance file. If your roofer won’t show you photos of the open deck before closing it, that’s a red flag.
Because the early 2000s wave of wood shake replacements near the Orange Line was done fast, and many installers skipped high-temperature ice and water shield at eaves and valleys. That omission shows up as valley leaks and staining 10 to 15 years in. The shingles look fine from the street, but the water is getting in at the seams. We’ve repaired dozens of these, and the fix is a proper tear-off of the valley section, new shield, and re-installation.
It can, but only if the documentation is real. Insurers want to see the product name, the wind rating, the nailing pattern, and ideally photos of the underlayment before the shingles went on. That’s exactly what we give you: a written record of every layer, a photo log, and a digital invoice by text. Many Winnetka homeowners have used this documentation to contest premium increases after the Santa Ana season. We can’t guarantee what your insurer will do, but we can guarantee you’ll have the paperwork to make the case. Call (650) 456-5615 to talk through your roof and your coverage.
