Oneills and Sons Roofing And Masonry: Best Roofing Services Serving New York, NY 10016

This is a common New York issue often caused by ice dam damage or worn flashing in roof valleys where water concentrates. Our process starts with a thorough roof inspection to pinpoint the exact problem. We then provide targeted repairs, which may include replacing damaged shingles, sealing valley flashings, or improving attic ventilation to prevent future ice dams. For severe cases, we can discuss reroofing with materials better suited to our climate.

Absolutely. As a full-service roofing and masonry contractor, we frequently handle combined projects. Water from a roof leak often causes secondary damage to masonry below, like patios or retaining walls. We can efficiently coordinate a roof repair or replacement alongside the necessary masonry/concrete repair, ensuring all work is seamlessly integrated. This saves you time and ensures the entire exterior envelope is properly addressed.

Proper gutters are your first defense against valley leaks. Clogged or poorly installed gutters can cause water to back up under roof shingles, especially in valleys. We offer complete gutter solutions: we'll clean existing gutters, repair any damage, or install a new, correctly sized system with adequate downspouts. This ensures meltwater and rain are efficiently channeled away from your roof's vulnerable valleys, preventing leaks at the source.
