Nick Varellas Roofing | Roofing Services in Merrick, NY 11566

In Merrick's humid climate, algae stains (black streaks) are common. While DIY cleaning can be risky, we recommend a professional soft wash treatment. We use eco-friendly solutions that safely remove the algae without damaging your shingles, and we can apply preventative zinc strips to inhibit future growth, protecting your roof's lifespan and appearance.

Chimney flashing leaks in Merrick often stem from aged sealant, corrosion, or improper installation that can't handle our seasonal expansion and contraction. A temporary patch usually fails. We perform a permanent repair by inspecting the step flashing and counter-flashing, replacing damaged sections with new, corrosion-resistant metal, and sealing it with high-grade urethane to create a lasting, watertight seal.

We advise a professional inspection after major storms, if you notice leaks or stains inside, or every 3-5 years as preventative maintenance. For Merrick homes, spring and fall are ideal times. We'll check for algae damage, compromised flashing, loose shingles, and wear in valleys—common trouble spots here—giving you a clear assessment and prioritized repair plan.
