Cruz Construction & Sons | General Contractors & Roofing in Uniondale, NY 11553

In our Uniondale climate, the most common cause is failed or aged sealant around the skylight frame and deteriorated flashing. We fix it by carefully removing the old sealant, inspecting and replacing any corroded flashing with durable, rust-resistant materials, and applying a high-grade waterproof sealant designed for Long Island's weather. A proper repair prevents interior water damage and mold.

Look for visible rust stains running down your roof or siding, especially around chimneys, vents, and valleys. You might also notice granules from your shingles accumulating in gutters near these areas. We recommend a professional inspection, as Cruz Construction & Sons can assess the extent of corrosion—common here due to salt air and moisture—and replace flashing before it leads to a major leak.

Yes, we provide a complete solution. For a skylight or flashing leak, our roofing team will make the permanent exterior repair. Then, our painting and construction crews can repair any stained or damaged drywall, ceilings, and insulation, repaint the affected areas, and ensure your interior is restored to its original condition. We manage the entire project so you have one reliable point of contact.
