Those dark streaks are often Gloeocapsa magma algae, common in our humid climate. While it can be cleaned, harsh pressure washing can damage shingles. We recommend a professional, low-pressure soft wash with an EPA-approved algaecide to safely remove the growth and help prevent it from coming back, protecting your roof's lifespan.

A sagging roof deck in Northport is a serious sign of potential structural issues, often from long-term water damage or failing supports. It requires immediate attention. We recommend you contact us right away for a safety inspection. We'll identify the cause—like compromised decking or trusses—and provide a clear plan for repair to prevent further damage to your home.

We advise a professional inspection at least once a year, ideally in spring or fall, and always after severe weather. Regular checks help catch small issues—like loose shingles or early algae growth—before they become major, costly problems like leaks or structural damage. It's a simple, proactive step to maintain your home's biggest protector.
