You can buy the most expensive shingles in the world, but if your attic isn't ventilated properly, that roof will fail prematurely. In the East Bay, where summer temperatures can soar, your attic can reach a staggering 150°F if the hot air has nowhere to go. This trapped heat literally "bakes" your roof from the inside out.
How Ventilation Works Proper ventilation is about balance: Intake and Exhaust.
Intake: Cool air enters through the soffit or eave vents.
Exhaust: Hot air rises and exits through ridge vents or solar-powered attic fans.
Signs of Poor Ventilation
Curling Shingles: Excessive heat causes the asphalt to harden and curl.
Ice Dams: In the winter, poor ventilation can cause uneven melting on your roof, leading to leaks.
Sky-High AC Bills: If your attic is 150°F, your air conditioner has to fight that heat through the ceiling just to keep your living room at 72°F.
When Sierra Roofing and Solar inspects a home, we don't just look at the shingles. We go into the attic to ensure your insulation isn't blocking your vents and that your "net free vent area" meets building codes. A well-ventilated roof lasts longer, performs better, and saves you money every single summer.
