Built for Heat, Sun, and Long-Term Performance

From Riverside to Rancho Cucamonga, Temecula to Redlands — Inland Empire summers are some of the most punishing in California. The difference between a roof that lasts 12 years and one that lasts 50 usually isn't the shingle. It's the system underneath.

Extreme Summer Heat & UV

Triple-digit summer days and intense UV cook the wrong roofing system from above. We install heat-resistant synthetic underlayments and shingles built for SoCal exposure.

Ventilation Matters Most

Most IE roof failures we see start with attic ventilation, not materials. Every project includes balanced intake-and-exhaust ventilation engineered for the home — not optional.

Underlayment Is Underrated

Standard 30-lb felt fails under sustained heat. Synthetic underlayment holds up to thermal cycling — the difference shows up at year 10, not year 1.

Complete Systems, Not Just Shingles

We don't sell shingle-only bids. Every IE project is a complete GAF or DaVinci system installed to manufacturer warranty spec.

Santa Ana Wind Protection

Roofs Built for Santa Ana Wind Country

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

When the Santa Ana winds rip through Riverside and San Bernardino counties each fall and winter, a roof is only as wind-resistant 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 Inland Empire 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 for Inland Empire Santa Ana season.

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

Inland Empire Roof Replacement Questions

The best system depends on budget and how long you plan to stay. GAF Timberline HDZ as a complete system with synthetic underlayment and balanced ventilation is the standard. For long-term homeowners, DaVinci synthetic systems handle sustained UV better than asphalt and carry a limited lifetime material warranty.

If your current roof has poor or unbalanced ventilation, a properly designed replacement can meaningfully reduce attic temperatures and extend the life of the new system. Every IE project we install includes a balanced intake-and-exhaust ventilation design — it's not an optional upsell.

Most Inland Empire residential roof replacements complete in 1–3 days. DaVinci synthetic installs may take slightly longer because of installation requirements. You'll get a clear schedule before the crew arrives.

Cost depends on roof size, pitch, layers being removed, and the system you choose. A GAF asphalt system on a typical IE single-family home will price very differently than a DaVinci synthetic install. The fastest way to a real number is the instant estimate — it pulls aerial data on your property in about 60 seconds.

Yes — we install both DaVinci Select Shake and Province Slate systems to DaVinci's specifications across the Inland Empire. They're an excellent fit for homeowners who want the look of natural shake or slate with little to no maintenance and Class A fire protection.

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 the Inland Empire. 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.

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 the financing page for the current status.
