Many homeowners believe the more insulated their roof is, the better. However, proper ventilation is needed not only for energy-efficiency but to prevent potential structural issues. As such, care should be taken not to block the vents in your attic—both the ones in your soffits and eaves that take air in and the ones leading to your ridge cap, where the air is exhausted. The guide below explains why this is so important. 

Why Do Roofs Need to Be Vented?

Heat rises. Therefore, without roof ventilation, the air in your attic will become excessively hot and stagnant with time. Superheating can cause your shingles to break down more rapidly, significantly decreasing their life span and putting your attic at risk of water intrusion the next time it rains.

If condensation starts to form, there is the potential for mold to grow; wood beams may also warp or rot. Because of these factors, properly ventilated roofs tend to have a longer life span.

What to Look for & What to Do About It

You should also be suspicious about your roof’s ventilation if you notice a persistent musty odor since it could mean your attic insulation has gone moldy. This poses both a structural risk and a potential health risk to your family.

If you notice these signs, call a roofing contractor for an inspection. If there isn’t a problem with the ventilation, the mold growth might be caused by a roof leak or similar problem, which should also be fixed immediately. They can then replace any damaged insulation.
