Poor attic ventilation is a common issue here, where warm, moist air gets trapped and condenses into frost. We assess your current ventilation system, often adding or adjusting soffit and ridge vents to create a continuous airflow. This prevents moisture buildup, reduces the risk of ice dams on your roof edge, and protects your insulation and interior from frost-related damage.

Skylight leaks here are often due to failed seals or flashing compromised by freeze-thaw cycles. A permanent repair isn't just a caulk job. We meticulously remove the old flashing, inspect the roof deck for water damage, and install new, ice-and-water shield protected flashing integrated with your shingles. This ensures a watertight seal that stands up to our local weather for years to come.

Absolutely. Old, drafty windows contribute significantly to indoor humidity by letting warm air escape and cold air in, forcing your HVAC system to work harder. This excess moisture can rise into the attic. By installing energy-efficient windows, we help stabilize your home's temperature and humidity levels, reducing the strain on your roof's ventilation system and helping prevent those condensation and frost problems.
