Five Boro Roofing & Sheet Metal Works | Roofing Services in Bronx, NY 10458

We use a specialized, low-pressure cleaning solution that safely removes black algae stains without scrubbing or harming your asphalt shingles. This Bronx-specific treatment kills the algae spores to prevent regrowth and helps restore your roof's appearance and longevity. We avoid harsh methods that can strip shingle granules and cause premature wear.

Skylight leaks here are often due to aged seals, improper flashing, or movement from seasonal temperature swings. We inspect the entire assembly—glass, frame, and flashing—to find the exact leak source. Our repair involves resealing with durable, flexible materials and often replacing the flashing to create a watertight seal that withstands Bronx weather, stopping leaks and preventing interior damage.

Absolutely. A skylight leak can allow water into your attic, leading to mold, rot, and insulation damage. Algae stains aren't just cosmetic; they can hold moisture and slowly degrade shingles, reducing their lifespan. Addressing these issues promptly with a professional repair from a local contractor like us prevents costly structural damage and maintains your home's value and safety.
