Roof ventilation is one of the most important and most overlooked parts of your roofing system. At Valley Roofing, we make sure every roof has proper ventilation so it performs the way it should, protects your home, and lasts as long as possible. For homeowners in Salem and across the Willamette Valley, ventilation plays a major role in preventing moisture issues, reducing energy costs, and extending the life of your roof.
Many homeowners don’t realize they have a ventilation issue until it becomes a bigger problem. If you’re noticing any of these, it’s worth having your ventilation system checked. Common signs include:
Poor attic ventilation can lead to heat and moisture buildup, which may cause mold, mildew, and wood rot over time. Trapped heat can also damage roof shingles, causing them to curl, crack, or lose granules, shortening the life of your roof.
A balanced attic ventilation system means having the right amount of intake and exhaust vents working together. Fresh air enters through intake vents (like soffit vents), while hot, moist air exits through exhaust vents (like ridge vents), helping prevent moisture buildup and improving overall airflow.
Gable vents and static roof vents can help with airflow, but they don’t always create a fully balanced system on their own. In most cases, combining intake and exhaust ventilation, like soffit and ridge vents, provides more consistent and effective results.
