Kern Construction | Roofing Services in Valley Stream, NY 11580

In our area, chimney flashing leaks are extremely common, often caused by aging sealant, storm damage, or improper installation. We fix this by carefully inspecting the existing flashing, removing any compromised material, and installing new, code-compliant flashing with durable, waterproof sealants. This targeted repair addresses the specific leak point to prevent future water intrusion into your home.

First, safely check for visible signs from the ground: missing or lifted shingles, damaged flashing around vents or chimneys, and debris on the roof. Wind can loosen materials and create immediate vulnerabilities. We recommend a professional inspection, as we can identify less obvious damage like cracked seals or weakened underlayment that could lead to leaks before the next rain.

Absolutely. For masonry, removing algae, moss, and salt deposits prevents moisture retention and surface deterioration. For roofs, gentle cleaning clears debris from valleys and around flashings, allowing for better water runoff and making it easier for us to spot potential issues during an inspection. Regular, professional pressure washing is a proactive maintenance step that helps extend the life of your home's exterior.
