Roof Ventilation in Palo Alto, California

The Palo Alto climate keeps the air damp through the winter. The moisture from the rain works its way into the attic, and without ventilation, the damp air sits and rots the deck. Roof ventilation in Palo Alto moves the damp air out and keeps the attic dry.

Signs Your Palo Alto Roof Needs Better Ventilation

• The attic feels damp or musty — the moisture is trapped
• Frost or moisture on the attic roof sheathing — the moisture is condensing
• The rooms upstairs are warmer than the rest of the house — the attic heat is radiating down
• The energy bill is high year-round — the ventilation is not working
• Mold or mildew in the attic — the moisture is not moving out

Why Palo Alto Roofs Need Ventilation

The Palo Alto climate is damp through the winter. The rain keeps the air humid, and the moisture works its way into the attic. Without ventilation, the damp air sits and condenses on the cold roof deck.

The condensation rots the deck and grows the mold. The ventilation moves the damp air out through the ridge vent and pulls the fresh air in through the soffit vents.

How We Ventilate Roofs in Palo Alto

1. Assess the attic — check the current ventilation, the insulation, and the airflow
2. Calculate the vent needs — the balanced intake and exhaust for the roof size
3. Install the ridge vent — the continuous vent at the peak of the roof
4. Install the soffit vents — the intake vents under the eaves
5. Balance the system — the intake and the exhaust work together

Preventing Roof Problems in Palo Alto

• Check the attic for moisture in the spring — the winter dampness is the test
• Check the attic temperature in the summer — the heat buildup is the test
• Keep the insulation at the floor, not the roof — the airflow needs the space
• Clear the soffit vents of debris — the blockages stop the airflow

Expert tip: in Palo Alto, the winter moisture makes the ventilation important. The damp air that sits in the attic is the cause of the deck rot and the mold.
