What Happens If A Roof Is Not Vented Properly

Katelyn Lewis • July 27, 2022

A proper attic ventilation system moderates the temperatures inside your home year-round, but it’s especially important in the high heat of summertime.


But what happens if a roof doesn't have proper attic vents?

If your roof is not properly vented, you may experience the following issues:

– Premature Roof Replacement. Excess heat and moisture inside your attic space can damage your shingles, roof decking, wood framing, ceilings, siding, and paint.

– Less Energy Efficiency. You’ll notice this issue in higher energy bills each month as you pump up the AC or heat, depending on the time of the year, to keep your home cozy.

– Potential Formation of Ice Dams. A hotter attic in the winter time can cause snow to melt and refreeze further down your roofline, creating damaging ice dams for your roof and gutters.

– Growth of Mold & Mildew. These two may pose a threat to your family’s health.

If you’re not sure whether your attic or roof is properly vented or you notice high energy bills each month, it’s wise to contact a professional roofing contractor to come check it out. If you’re a homeowner in the Greater Richmond, VA, region, Retex Roofing & Exteriors’ experts are here to help.
