In Portsmouth, with views of the Sakonnet River, farms and coastal neighborhoods, roofs work through salt air, wind, fog and strong sun. Roof ventilation helps your attic handle all of that without trapping heat and moisture.

When an attic can breathe, cooler air comes in low and warmer, moist air moves out high. That gentle airflow helps:

• Keep attic temperatures more reasonable in summer.
• Reduce condensation that can lead to mold, mildew and wood damage.
• Limit ice dams along the roof edges in winter.
• Support longer shingle and roof deck life.

Warning signs in Portsmouth homes include very hot attics on warm days, musty odors upstairs, rusty nails or hardware in the attic and frost or dark staining on the underside of the roof deck in winter.

A balanced coastal system usually includes:

• Intake vents at the soffits to draw cooler outside air into the attic.
• Exhaust vents at the ridge or high on the roof to let hot, moist air escape.

When we replace a roof in Portsmouth, we check ventilation alongside shingles, flashing and decking. If intake or exhaust is lacking, we correct it as part of the project so your new roof can handle local weather better.
