The dark streaks on your roof are likely Gloeocapsa magma algae, common in our humid climate. We don't recommend high-pressure washing, as it can damage shingles. Instead, we use a specialized low-pressure soft wash system with EPA-approved cleaners that safely kill the algae at the root without harming your roof. To prevent regrowth, we can install zinc or copper strips along the ridge, which release ions that inhibit algae growth with each rain.

Signs of underlayment damage include interior water stains, leaks during heavy rain, or a spongy feeling when walking on the roof. The underlayment is your roof's secondary water barrier, and in Lake Mary's frequent storms, a compromised layer can lead to major leaks and structural rot. Our inspection involves safely checking vulnerable areas like valleys and eaves. We then carefully remove affected shingles, replace the damaged underlayment with high-quality synthetic material, and re-seal everything to restore your roof's integrity.

In many cases, a targeted repair is perfectly sufficient. We always start with a comprehensive, no-obligation inspection to assess the extent of the damage. For localized issues like a few damaged shingles from a storm or a small area of underlayment failure, a precise repair is the most cost-effective solution. We'll match your existing shingles as closely as possible. We only recommend a full replacement if the roof is near the end of its lifespan or if the damage is widespread, ensuring you only invest what's truly necessary for your home's protection.
