Proper ventilation is critical in our climate to prevent heat and moisture buildup in your attic. Without it, you risk ice dams in winter, which can cause leaks and structural damage, and excessive heat in summer that can warp shingles and raise energy costs. We assess and correct ventilation issues to protect your roof's integrity year-round.

Those streaks are typically Gloeocapsa magma algae, which thrives in our humid, coastal environment. While it can look unsightly, it also retains moisture that degrades shingles over time. We offer professional cleaning to safely remove the stains and can install algae-resistant shingles on new roofs or replacements to prevent future growth.

After storms, check for missing or damaged shingles, especially in valleys and around chimneys. Look for signs of moisture in your attic, sagging roof lines, and excessive granule loss in gutters. Given our weather, also keep an eye out for early algae staining or moss growth. We recommend a professional inspection at least once a year to catch issues early.
