Proper attic ventilation is one of the most overlooked parts of a roof — and one Dee's Roofing never skips. Balanced airflow lowers energy bills, controls moisture and helps your roof last.
Your attic needs to breathe. On a hot July afternoon in Knoxville, an unvented attic can get far hotter than the air outside, baking shingles from below and making your air conditioner work overtime. In winter, warm, moist air from the house rises into the attic and condenses on cold decking, leading to mold, rot and frost. Proper roof ventilation solves both problems by moving air steadily through the attic.
A good system balances intake and exhaust. Cool air enters low through soffit vents, and warm air exits high through a ridge vent or other exhaust vents. When that balance is off — blocked soffits, too few vents, or mixed vent types fighting each other — problems follow. Dee's evaluates your attic and corrects the ventilation as part of every roof we install, and we also take on ventilation upgrades as a stand-alone service.
This is something Darrell feels strongly about. Ventilation lowers energy costs, extends roof life, and helps protect your shingle manufacturer's warranty, which may not apply to an attic that isn't vented properly.
Balanced attic ventilation protects your roof and your wallet.
A cooler attic in summer means your air conditioning doesn’t have to work as hard.
Shingles last longer when they aren’t baked from underneath.
Steady airflow prevents condensation that leads to mold and rotted decking.
Many shingle manufacturers require proper ventilation to honor their warranty.
Poor ventilation often shows up indirectly: upstairs rooms that are hard to cool, high summer energy bills, shingles that curl or blister early, a musty smell in the attic, or dark staining and mold on the underside of the decking.
One of our customers called about a mold problem that seemed to appear overnight and expected a costly disaster. The real cause was inadequate ventilation — and fixing it was a much simpler, more affordable job than he feared.
If you're noticing any of these signs, a free inspection will tell you whether your ventilation is part of the problem.
Here's what a ventilation evaluation and upgrade from Dee's includes.
High cooling bills, hot upstairs rooms, early shingle wear, a musty attic smell, or mold on the underside of the decking are common signs. We'll check during a free inspection.
A ridge vent runs along the peak of the roof and lets hot, moist air escape from the attic. It works best when paired with soffit vents that bring cooler air in low.
Yes. Warm, moist air that can't escape condenses on cold surfaces in the attic, which can lead to mold and rotted decking.
Often, yes. Soffit vents can be opened or added, and ridge vents can sometimes be installed on an existing roof.
It can. Many shingle manufacturers require proper attic ventilation, and an improperly vented attic may affect warranty coverage.
