What Fontana Roofs Actually Deal With
Fontana sits at the mouth of the Cajon Pass — when Santa Ana winds funnel through, Fontana roofs take some of the strongest sustained gusts in the Inland Empire. Combine that with extreme summer heat and a huge stock of 1980s–2000s builder-grade tract roofs, and full system replacement is the right call for much of the city. Local material selection, flashing package, and ventilation strategy all matter — a generic SoCal install template doesn't perform the same way in Fontana as it does two counties away.

Why Your Fontana Roof Should Be Installed as a System
A roof isn't just shingles. Underlayment, leak barriers, ventilation, flashings, and ridge components all matter — and most failures come from the layers under the shingle, not the shingle itself.
Synthetic Underlayment
Not 30-lb felt. Tear-resistant, water-shedding, and built to outlast the shingle layer.
Leak Barriers Where It Counts
Eaves, valleys, and penetrations — the spots that fail first on basic installs.
Balanced Ventilation
Intake and exhaust matched to actual attic volume — radically extends shingle life.
Premium Flashings
Pipe boots, step flashing, valley metal, ridge — installed to manufacturer spec.
Manufacturer-Matched System
Complete GAF or DaVinci system — what unlocks enhanced warranty coverage.
Full Deck Inspection
Every Westmark project starts with a full tear-off and structural deck inspection.
