Roofing Systems That Match Orange County Homes

From Newport Beach to Yorba Linda, Orange County homes set a high bar — for curb appeal, for property value, and for the contractors who work on them. We install premium GAF and DaVinci systems with the kind of professional process those homes deserve.

Curb Appeal & Property Value

In OC neighborhoods, the roof is part of the home's value story. GAF Grand Sequoia and DaVinci shake/slate systems deliver visual depth that flat asphalt can't.

Older Stock Meets High-Value Estates

Mid-century inland homes and coastal estates need different system choices. We match the system to the home — not a one-size-fits-all bid sheet.

Heat, UV & Aesthetics

Inland heat and full-day sun age the wrong shingle fast. We use systems built for SoCal exposure — with the look homeowners actually want.

Replacement, Not Repair

We focus exclusively on complete residential reroofing projects. No commercial work. No isolated patch jobs.

Santa Ana Wind Protection

Roofs Built for Santa Ana Wind Country

GAF WindProven Roofing System Limited Warranty — Infinite Wind Speed Protection badge

The Santa Ana winds are named for Orange County's own Santa Ana Canyon — and every fall and winter they hammer foothill and canyon-adjacent homes from Yorba Linda to Anaheim Hills. A roof only resists that wind as well as the system holding it down. Because Westmark installs GAF Timberline® shingles with GAF LayerLock™ Technology as a complete GAF system — with the required GAF accessories — qualifying Orange County roofs are eligible for the GAF WindProven™ Limited Wind Warranty, the industry's first wind warranty with no maximum wind speed limitation.

No Maximum Wind Speed Limit

Most wind warranties cap out at a set mph. WindProven has no maximum wind speed limitation — important coverage when the Santa Anas tear through OC's canyons.

No Named-Storm Exclusion

Many wind warranties carve out major wind events with a 'named storm' clause. WindProven has none — coverage holds regardless of the storm.

No Extra Cost, No Registration

When we install the qualifying LayerLock shingle (Timberline HDZ) and GAF accessory package, eligible roofs get this coverage at no added cost — stacked on top of the lifetime Golden Pledge.

Eligibility and coverage terms are defined by GAF's WindProven Limited Wind Warranty.

FAQs

Orange County Roof Replacement Questions

GAF Timberline HDZ remains the most installed system overall, but a large share of OC projects move up to GAF Grand Sequoia (designer asphalt) or DaVinci synthetic shake/slate for the visual depth and longer lifespan. We help you pick based on the home's architecture and how long you plan to stay.

For long-term homeowners or higher-value properties, yes. DaVinci synthetic systems carry a Limited Lifetime Material Warranty, are Class A fire and Class 4 impact rated, and don't rot, mold, or fade the way natural shake does. The upfront cost is higher than asphalt, but it's the last roof you install.

Not yet for standard roofing projects — those are payable by cash or check, and a Westmark financing program may become available in the future. One exception: integrated GAF Timberline Solar projects are contracted directly with GAF, which makes third-party financing options available. See our financing page for the current status.

If your roof is past 15–20 years, has multiple leak history, missing or curling shingles, or the underlayment is failing, replacement is almost always the better long-term call. We don't do partial repairs — but we'll tell you honestly if a replacement isn't yet warranted.

Every GAF system we install includes the GAF Golden Pledge — lifetime coverage on material defects, labor, and workmanship, on all qualifying GAF system components. DaVinci synthetic carries a Limited Lifetime Material Warranty. Real-world lifespan depends heavily on installation quality and ventilation — both of which we control.

Yes — from coastal Newport Beach and San Clemente to inland Yorba Linda and Anaheim, we cover Orange County as part of our standard Southern California service area.

Qualifying GAF Timberline HDZ roofs we install are eligible for the GAF WindProven™ Limited Wind Warranty — the industry's first wind warranty with no maximum wind speed limitation and no named-storm exclusion. It applies when we install GAF Timberline® shingles with LayerLock® Technology as part of a complete GAF system with the required GAF accessories, which is how we build our Timberline HDZ roofs across Orange County. It carries a 15-year limited wind term at no extra cost and no registration, layered on top of the lifetime Golden Pledge. Eligibility and coverage terms are defined by GAF's WindProven Limited Wind Warranty.
