Proper Ventilation Helps Your Roof Last Longer

Here is an example of how proper ventilation helps your roof last longer. We had to replace the roof on this multifamily home, and here’s why.

The original roof had inadequate soffit and ridge ventilation. In addition, the bathroom exhaust fans were venting directly inside of the attic. These problems caused enough condensation in the attic over the years to allow mold and mildew to form on the plywood and cause the plywood over the entire roof to rot.

A soffit is a material that lines the underside of a roof’s overhang, also known as the eaves or rafters. Soffits can also be found on the underside of a porch roof.

Soffits have several important functions, including ventilation. Soffits can be vented to allow airflow into the attic, which helps prevent heat buildup and keeps the roof dry and mold-free.

A ridge vent is a long, low-profile ventilation system that runs along the peak of a sloped roof to allow for air circulation and exhaust within the attic. Ridge vents are a type of passive ventilation system that uses natural forces like wind and convection to move air through the attic, removing hot and humid air and pulling fresh air in. This helps regulate temperature and humidity levels, which can prevent damage to the roof structure from moist air. Ridge vents can also help extend the lifespan of a roof

First, we removed the existing shingle roofing and the original rotted plywood, being careful not to fall through the roof. New 5/8″ plywood was installed with a Landmark roof shingle by Certainteed, along with seamless gutters. The soffit and ridge vents were improved, and the bathroom exhaust fans were properly vented.
