Roof Ventilation in Gilroy, California

The attic is the part of the roof that nobody sees, but it does the most work. The summer heat builds up in the attic, and the roof deck takes the damage. Roof ventilation in Gilroy means the air flow that keeps the deck cool and dry.

Signs Your Gilroy Home Needs Better Ventilation

• Hot attic in the summer — the heat is baking the shingles from below
• Condensation on the attic deck — the warm air met the cold surface
• Peeling exterior paint near the eaves — the heat and the moisture pushed through
• High cooling bills — the attic heat is seeping into the living space
• Shingles aging fast on the south slopes — the heat is cooking them

Why Gilroy Roofs Need Ventilation

The summer heat is the main reason. The South Bay sun bakes the roof, and the heat builds up in the attic. The shingles that are cooked from below age faster than the ones that are vented.

The winter rain adds the moisture. The condensation forms on the cold deck, and the moisture breeds the mildew and the rot that the ventilation would prevent.

How We Install Ventilation in Gilroy

1. Inspect the attic — check the current vents, the insulation, and the deck
2. Calculate the needs — the square footage of the attic determines the vent area
3. Install the soffit vents — the intake vents in the eaves
4. Install the ridge vent — the exhaust vent at the peak
5. Verify the flow — the smoke test confirms the air is moving
