FAQs
What is chimney flashing and why is it important for my Harrison home?
Chimney flashing is a waterproof barrier—typically sheet metal combined with high-grade sealants—that connects your chimney to the surrounding roof surface. It diverts rain and melting snow away from the joint where masonry meets roofing, preventing leaks, wood rot, mold growth, and structural damage. Because Harrison experiences frequent freeze-thaw cycles and heavy spring rains off the Long Island Sound, properly installed flashing is essential to protect both your roof deck and interior ceilings.
How can I tell if my chimney flashing needs repair or replacement?
Warning signs include water stains on ceilings near the chimney, damp attic insulation, rusted or lifted metal, cracked masonry next to the flashing, and shingle granules collecting in gutters. You might also notice a musty odor during wet weather. If you see daylight around the chimney from the attic or observe flashing that has separated from the brick, schedule an inspection right away—small leaks can become costly structural fixes in Harrison’s humid summers and cold winters.
What materials do you use for chimney flashing repairs, and which is best for Harrison’s climate?
We work with copper, galvanized or stainless steel, and high-quality aluminum. Copper is the premium choice for Harrison because it resists corrosion, expands and contracts evenly with temperature swings, and can last 50+ years. Galvanized steel is budget-friendly and durable when paired with ice-and-water shielding. Aluminum is lightweight and effective but requires proper coating to avoid galvanic reaction with masonry. During our on-site assessment, we’ll recommend the material that matches your roof type, budget, and the coastal weather conditions here in Westchester County.
How much does chimney flashing repair or replacement typically cost in Harrison?
Costs vary with roof pitch, chimney size, and material selected. Minor resealing or step-flashing tune-ups start around $350–$500. Full removal and replacement with copper flashing on an average two-story home generally ranges from $1,200 to $2,000. Complex roofs, slate or tile surfaces, or masonry repairs done simultaneously can raise the price. We provide written estimates after a free inspection so you know exactly what to expect—no surprise add-ons.
How long will the repair take and will it disrupt my daily routine?
A straightforward flashing repair or replacement is usually completed in one day. We begin with protective tarps, remove old materials, install new step and counter flashing, apply sealants, and test for watertightness. You can stay in your home during the work; noise is minimal and cleanup is handled before we leave. If your chimney needs masonry repointing or your roof decking requires replacement, the project may extend to two days, but we’ll outline the schedule in advance.
Do you offer warranties for chimney flashing work and can you help with insurance claims?
Yes. All new chimney flashing installations come with a 10-year workmanship warranty and a material warranty based on the metal chosen (up to 50 years for copper). If your flashing was damaged by storms, fallen branches, or ice dams, many homeowner policies cover repairs. Our team documents the damage with photos, provides the required estimate format, and communicates directly with your adjuster to streamline the claim so you receive the reimbursement you’re entitled to.
