Those dark streaks are often Gloeocapsa magma algae, common in our humid climate. While gentle cleaning can help, improper methods can damage shingles. We assess the roof's condition to determine if a professional soft wash is safe and effective, or if the staining indicates it's time to consider replacement with algae-resistant shingles for a longer-term solution.

It can be both. Often, overflow is caused by clogged or undersized gutters, but it can also stem from improper roof pitch or flashing issues that send too much water to one area. We'll inspect both your roof edge and gutter system to identify the root cause—whether it requires cleaning, re-sizing gutters, or adjusting the roof's water runoff—to protect your home's siding and foundation.

We recommend a professional inspection at least once a year, ideally in late spring or early fall. Our coastal weather with high humidity, storms, and temperature swings can accelerate wear. An annual check allows us to spot early signs of algae, loose shingles, or gutter issues before they lead to leaks or structural damage, saving you money and stress in the long run.
