Rivertowns Roofing and Siding | Roofing Services in Tarrytown, NY 10591

In Tarrytown, the most common cause is failed chimney flashing—the metal strips that seal the joint between the chimney and roof. Winter freeze-thaw cycles and summer heat can crack the old sealant or loosen the flashing. We fix it by carefully removing the old material, inspecting for rot in the surrounding decking, and installing new, code-compliant step flashing integrated with a waterproof membrane for a long-lasting seal.

Roof valleys are high-traffic channels for water and debris. Leaks often start from worn valley metal, cracked shingles, or improper installation that allows water to seep underneath. We offer two solutions: For localized damage, we perform a precision repair by replacing the compromised section with new valley lining. For widespread wear or on older roofs, we often recommend installing a new, continuous open metal valley, which is highly durable and provides superior water shedding for our climate.

In our area, a leak is an emergency if you see active water dripping inside, especially near electrical fixtures, or if there's a sudden sag in your ceiling. For less urgent signs like a small stain, contain it with a bucket and call us for a prompt inspection. We offer emergency tarping services to prevent further water intrusion until we can perform a permanent repair, protecting your home from mold and structural damage common with prolonged moisture in Tarrytown's humid seasons.
