Roof Contractors in Westchester, NY Your roof is your home’s first line of defense — against rain, snow, wind, and everything Westchester’s four distinct seasons throw at it. When it fails, the damage rarely stays on the roof: leaks travel into attic insulation, ceiling drywall, and eventually walls and foundations. American Star Contractor is a licensed, insured roofing contractor serving Westchester County, NY, including White Plains, Scarsdale, Yonkers, New Rochelle, Mount Vernon, and surrounding towns, offering roof repair, installation, replacement, and leak repair. Why Hiring the Right Roof Contractor Matters Roofing is one of the few home systems where a bad repair costs more than doing nothing — a poorly flashed patch or mismatched shingle can trap moisture and accelerate the exact damage it was meant to fix. A qualified contractor doesn’t just cover the visible problem; they check the roof deck, underlayment, flashing, and ventilation underneath it, because a leak on the surface is often a symptom of a failure below it. Working with a licensed, insured Westchester roofing contractor also protects you legally and financially: proper permits, manufacturer-backed warranties on materials, and workmanship guarantees are only available when the installer is certified to provide them. Our Roofing Services Roof repair. From missing or curling shingles to damaged flashing around chimneys and skylights, our team diagnoses the actual source of a leak — not just the spot where water is showing up inside — and repairs it so the fix holds through the next storm. See our Westchester roof repair page for service details. Roof installation. For new construction or homes going from a different exterior material, we handle full roof system installation — deck inspection, underlayment, ice and water shield in vulnerable areas, and shingle or material installation to manufacturer spec. Details on our Westchester roof installation page. Roof replacement. When a roof is past the point where repair makes sense — widespread granule loss, multiple leak points, or age beyond its expected lifespan — we handle full tear-off and replacement, with options across shingle types and price points.

Our team locates the entry point — often flashing, a cracked vent boot, or a compromised seam rather than the shingles themselves — and seals it properly the first time instead of applying a temporary patch. Roofing maintenance. Periodic inspection and minor upkeep — clearing debris, resealing flashing, checking for granule loss — catches small issues before they become leaks, extending the life of a roof that’s otherwise in good shape. Common Roofing Problems We Fix Missing, cracked, or curling shingles from wind, age, or hail Damaged flashing around chimneys, skylights, and roof valleys — the single most common leak source Granule loss on asphalt shingles, a sign of aging material that’s losing its protective coating Ice dam damage where ice buildup at the eaves forces water back under shingles Sagging roof deck from long-term moisture exposure or structural stress Ventilation issues that trap heat and moisture in the attic, shortening the roof’s lifespan from underneath Materials We Install and Repair Most Westchester homes use asphalt shingles — either three-tab or the more durable, longer-warrantied architectural (dimensional) shingles. We work with major manufacturer lines and can walk you through the trade-offs between standard and architectural shingles, including warranty length, wind rating, and appearance, based on your home and budget. Signs You Need a Roofing Contractor Water stains on ceilings or upper walls, especially after rain Shingles that are missing, cracked, curling at the edges, or covered in visible granule loss in the gutters Daylight visible through the roof boards in the attic Sagging areas anywhere on the roofline Rising energy bills with no other explanation — often a sign of failing insulation or ventilation A roof older than 20 years that hasn’t had a professional inspection recently Our Process Inspection. We physically walk the roof — not just a photo from a drone or the ground — to assess shingles, flashing, deck condition, and ventilation. Written estimate. You get a clear, itemized quote before any work starts, whether it’s a repair or full replacement. The work. Repairs, installation, or replacement is completed using manufacturer-spec materials and technique, with attention to the underlayment and flashing details that determine whether a roof actually performs. Final walkthrough and cleanup. We review the completed work with you and leave the property clean. Repair vs. Replacement: How to Decide Repair makes sense when damage is localized — a section of missing shingles, one flashing failure, an isolated leak — on a roof that’s otherwise structurally sound and within its expected lifespan. Replacement is the better call when the roof is near or past its rated lifespan (typically 20-25 years for asphalt shingles), has multiple active leaks, or has been repaired repeatedly without resolving the underlying issue. We’ll give you a straight recommendation based on the roof’s actual condition, not the size of the job.

Frequently Asked Questions How much does a roof repair cost in Westchester? It depends on the extent of the damage and the materials involved — a single flashing repair costs far less than replacing a full section of shingles. We provide a free, itemized estimate before any work begins. How do I know if I need a repair or a full roof replacement? If the damage is localized and the roof is otherwise sound and within its expected lifespan, repair is usually the right call. If the roof is old, has multiple leak points, or has been patched repeatedly, replacement is typically more cost-effective long term. How long does a roof replacement take? Most residential roof replacements are completed in one to three days, depending on the size of the roof, the material, and weather conditions. Do you offer emergency
