JJM Roofing & Waterproofing | Waterproofing & Roofing in Westbury, NY 11590

In Westbury's climate, repeated freeze-thaw cycles can quickly compromise roof flashing, leading to leaks. Our approach is twofold: first, our thorough inspections during repairs or replacements identify and address existing corrosion. Second, for new installations, we use high-quality, corrosion-resistant flashing materials and precise installation techniques designed to withstand Long Island's specific weather patterns. This targeted method helps prevent the water intrusion that often appears as snow melts.

We provide full siding installation, repair, and replacement. Beyond improving curb appeal, new siding acts as a critical first line of defense against moisture. For older Westbury homes, replacing worn siding stops water from seeping behind the walls, which protects your home's structure and improves energy efficiency by sealing drafts. Our installation ensures a tight, weather-resistant barrier that complements our waterproofing solutions.

Our lifetime manufacturer warranty covers defects in the roofing materials themselves for as long as you own your home. This is separate from our workmanship guarantee. It provides long-term peace of mind, knowing the shingles, tiles, or slate are protected. We provide all warranty details upfront and use only high-quality products from trusted manufacturers to ensure this coverage is robust and reliable for Nassau County homeowners.
