Home » Blog » Merrimack Valley Roofing Highlights Importance of Attic Ventilation During Roof Replacement

FOR IMMEDIATE RELEASE

SANDOWN, N.H. – Merrimack Valley Roofing and Gutters LLC is reminding homeowners that attic ventilation should be reviewed as part of any roof replacement project.

Poor attic ventilation can trap heat and moisture beneath the roof deck, shortening shingle life and contributing to condensation or winter ice problems. Proper intake and exhaust ventilation help the roof system perform as intended.

“Replacing shingles without checking airflow can leave an important part of the roof system unresolved,” said Barry James. “Ventilation, flashing, underlayment, and gutters all matter.”

Merrimack Valley Roofing reviews roof systems for shingle condition, deck concerns, flashing, gutter performance, and ventilation indicators. The company serves homeowners throughout the Merrimack Valley region.
