Star Construction | Roofing Services in Cambridge, MA 02141

In our climate, poor ventilation traps heat and moisture in your attic. This can lead to premature shingle deterioration, ice dams in winter, and high cooling costs in summer. It also creates a perfect environment for mold and rot in your roof decking. Our team assesses your attic's airflow and installs balanced intake and exhaust systems to protect your home.

Moss holds moisture against your shingles, causing them to decay and potentially leading to leaks. We don't recommend power washing, as it can damage shingles. Our method involves a professional-grade treatment to safely kill the moss, followed by gentle manual removal. We can also install zinc or copper strips at the roof ridge to prevent future growth, a common and effective solution for local homes.

Watch for excessive heat in your upstairs rooms, visible ice dams along the eaves, or peeling paint on exterior overhangs—these suggest ventilation issues. For moss, look for black algae streaks or green, spongy patches on north-facing or shaded roof sections. If you notice either, it's wise to schedule an inspection. We'll identify the root cause and recommend a targeted solution to prevent further damage.
