Those black streaks are likely algae, which is common here due to our humidity. While they can be unsightly, a professional soft wash with specialized cleaners is the safest and most effective solution. We avoid high-pressure washing, which can damage shingles, and instead use treatments that eliminate the algae and help prevent it from returning quickly.

Signs of roof deck rot in our area often include sagging roof lines, spongy feeling underfoot in the attic, or water stains on interior ceilings. A professional inspection from Gem Roofing can confirm this. Repair involves safely removing the affected shingles, replacing the rotted decking with new, treated plywood, and ensuring proper underlayment and ventilation are installed to prevent future moisture issues.

In our climate, poor ventilation traps heat and moisture in your attic. This creates the perfect environment for roof deck rot to develop from the inside out and can accelerate algae growth on the outside. Proper ventilation allows air to flow, regulating temperature and moisture levels. It's a critical, often overlooked, defense against the most common local roofing problems we see.
