Excelsior Systems | Roofing Services in Lansing, NY 14882

Lansing's weather cycles of snow, ice, and rain create a perfect environment for corrosion, especially on older aluminum or steel flashing. This repeated wetting and drying, combined with road salt exposure in winter, can accelerate wear. We address this by inspecting your flashing during routine checks and using modern, corrosion-resistant materials for any replacements to ensure a lasting seal.

We use a careful, low-pressure cleaning method with EPA-approved, biodegradable solutions to kill the moss at the root. Harsh pressure washing can strip protective granules from asphalt shingles. After cleaning, we apply a zinc or copper-based treatment at the roof's peak. As rainwater washes over it, this creates a protective barrier that inhibits future moss and algae growth, a crucial step for Lansing's shaded, damp areas.

Look for visible rust or green patina on metal around chimneys, vents, or valleys. Inside, water stains on ceilings or walls near these roof penetrations are a major red flag. Even minor corrosion can compromise the watertight seal. We recommend a professional inspection, especially after severe weather, to catch issues early and prevent the interior water damage common in our area.
