Union Construction USA | Roofing Services in Bronx, NY 10462

A proper roof installation is the best defense against roof deck rot. We start by thoroughly inspecting and replacing any rotted decking. Then, we install high-quality underlayment and shingles with precise ventilation to prevent moisture buildup. For reroofing, we address hidden rot and upgrade flashing around chimneys and vents—common failure points in our climate—to ensure a watertight seal that protects the structural wood beneath for years.

Not always. Flashing corrosion is a common local issue, but it often requires targeted repair, not a full replacement. Our roof inspection will pinpoint the exact source. We specialize in flashing repair and replacement using corrosion-resistant materials. If the surrounding shingles and decking are still sound, we can fix the flashing to stop the leak immediately, saving you the cost of a premature full roof replacement.

Integrating waterproofing from the start is crucial. For additions like balconies, decks, or bathroom remodels, we install moisture barriers and proper drainage systems to protect the new structure from the ground up. This prevents the same rot and corrosion issues that affect roofs. For existing spaces, our moisture control inspections and repairs seal vulnerable areas, ensuring your investment stays dry, safe, and adds lasting value to your home.
