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, and quote concrete or clay tile by homeowner request, 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
Complete residential reroofing is our specialty. Select commercial projects are considered after scope review. No isolated patch jobs.
What We Install in Orange County
Complete Roofing Systems — Not Just Shingles

GAF Timberline HDZ Systems
The most popular architectural asphalt system in North America — installed as a complete GAF system, not just shingles.

Santa Ana Wind Protection
Roofs Built for Santa Ana Wind Country
_1782855576989-C4AifEov.png)
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.
