The Importance Of Attic Ventilation
A good roof is much more than the shingles covering it. Several other factors decide whether the roof actually performs — and the most overlooked of them is ventilation.
With poor ventilation, insulation R-values mean very little, decay and rot set in, and a string of other problems follow. A great many homes around Santa Rosa don’t have the attic ventilation they need, simply because nobody ever told the owner it mattered.
Summertime temperatures in a poorly ventilated attic can exceed 160 degrees. Add the vapour and condensation that poor ventilation traps up there, and it stops being a minor issue.
Here’s what that actually leads to:
- Hot air building in the attic until it pushes down into the living area
- Premature ageing and damage to the shingles
- Warping and cracking of the framing
- Damage to siding and paint
- Mildew growth
- Buckling shingles
- Higher energy bills
What Good Ventilation Actually Does
A properly ventilated attic moves hot air out, which reduces the load on your AC system. That means a longer life for the unit and lower cooling costs at the same time.
There’s a moisture side too. Showers and household appliances push moisture up into the attic. If it isn’t vented out, it builds and eventually settles onto the insulation — and wet insulation stops working. If you’ve recently paid for an insulation upgrade, poor ventilation is what undoes it.
How It Works
Getting Better Ventilation
A well-ventilated attic comes down to one thing: a continuous flow of air moving through it. Here’s how that’s achieved.
-
Air In At The Soffits
Soffits or eaves draw fresh air into the attic at the low point. Blocked or painted-over soffit vents are one of the most common faults we find.
-
Air Out At The Ridge
That air is expelled through the roof ridge vents at the high point, carrying heat and moisture out with it. Intake without exhaust doesn’t work, and neither does the reverse.
-
The Right Amount
The FHA recommends at least one square foot of ventilation for every 300 square feet of attic space. We measure yours against that and tell you where it stands.
