Roof Ventilation Problems in Idaho

Poor attic ventilation is one of the fastest ways to shorten roof life. In summer, heat bakes shingles from below. In winter, warm attics contribute to ice dams.

Signs of ventilation problems

• Shingles aging faster than expected.
• Hot upstairs rooms in summer.
• Frost or condensation in attic during winter.
• Ice dams forming regularly at eaves.

Common causes

• Blocked soffit intake.
• Not enough exhaust (ridge/box vents).
• Bathroom fans dumping into attic.
