Vision Roofing Long Island | Roof & Skylight Leak Repair, Siding, Waterproofing

A persistent valley leak often indicates underlying issues like improper flashing, ice dam damage, or worn valley metal. Our expert repair process starts with a thorough inspection to diagnose the root cause. We then address it with precise flashing replacement, high-quality sealants, and, if needed, a section of valley replacement using materials rated for our local weather. The goal is a permanent fix that prevents water intrusion and protects your home's structure.

Absolutely. In many cases, a skylight leak is due to failed flashing or sealants around the unit, not the roof shingles themselves. Our skilled technicians specialize in targeted repairs. We carefully remove the surrounding shingles, inspect and replace the step flashing and counter-flashing, apply new waterproofing membranes, and re-secure everything with proper techniques. This focused approach often resolves the leak efficiently, saving you the cost of a full roof replacement.

Damaged or aging siding is a major entry point for moisture, which can lead to rot, mold, and structural issues inside your walls. On Long Island, where wind-driven rain is common, this is a critical concern. Our siding repair and replacement services seal your home's envelope. We fix cracks, replace warped panels, and ensure proper installation with integrated moisture barriers and flashing. This not only improves curb appeal but is a vital part of comprehensive moisture control, working with your roof and waterproofing to keep your home dry and healthy.
