Does my attic have enough ventilation?
Proper attic ventilation lets hot, moist air out of the attic. Without enough ventilation, heat builds up under the roof and can shorten the life of your shingles. A roof inspection can tell you whether your attic is ventilated properly.
Why ventilation matters
In a North Texas summer, an attic can get much hotter than the air outside. That heat can cause shingles to age faster. Trapped moisture can also condense on the underside of the roof decking in cooler months.
Intake and exhaust
A ventilation system needs both intake and exhaust. Air usually comes in at the soffits, low on the roof, and leaves through vents at or near the ridge. Exhaust vents work best when there is enough intake to feed them.
Types of roof vents
Common options include ridge vents, turbines, power and solar vents, and low profile vents. The right combination depends on the size and shape of the roof.
A good time to review it
A roof replacement is a good time to look at your ventilation, since the roof is already being worked on. When we replace a roof, we discuss your options for exhaust and attic ventilation with you.
Frequently Asked Questions
Is a ridge vent better than turbines?
Both can work well. The right choice depends on the roof and the amount of intake ventilation.
Will better ventilation lower my energy bill?
It can help lower attic temperatures. Its main benefit is helping your roof last.
How do I know if my soffit vents are blocked?
Insulation pushed against the soffits is a common cause. It can often be seen from inside the attic with a flashlight.
