FAQs
What are the most common signs that my roof flashing is failing?
Look for water stains or damp spots on interior ceilings and walls, rust or corrosion on exposed flashing metal, lifted shingles near chimneys or valleys, and visible gaps or cracks where flashing meets brick or siding. In Harriman’s wet spring and storm-heavy summer, even small separations can let in significant moisture, so it’s best to inspect after every major rain event.
Why is it critical to repair damaged flashing right away?
Flashing is the watertight barrier that seals joints around chimneys, skylights, walls, and valleys. When it deteriorates, wind-driven rain can work beneath shingles and soak the roof deck, leading to rot, mold, and interior drywall damage. Prompt repairs save you from larger structural repairs that are far costlier than fixing flashing early.
How does Harriman’s climate contribute to flashing failure?
Harriman experiences freeze–thaw cycles in winter and high UV exposure in summer. Temperature swings cause metal flashing to expand and contract, loosening nails and sealant. Heavy thunderstorms can then force water into newly formed gaps. Humid summers accelerate corrosion on galvanized steel flashing, shortening its lifespan if not maintained.
Can I patch the flashing or does it need full replacement?
If the damage is limited to minor pinholes or a single loose section, a professional can often clean, reseal, and secure the existing flashing. However, widespread rust, cracking, or separation usually requires full replacement to guarantee a lasting seal. An on-site inspection lets us recommend the most cost-effective and durable solution.
What is the typical flashing repair process and timeframe?
1) We perform a detailed inspection and moisture scan. 2) Damaged shingles or siding are carefully lifted. 3) Old flashing is removed or cleaned. 4) New corrosion-resistant aluminum or copper flashing is installed with proper overlap and high-grade sealant. 5) Shingles are re-laid and seams are water-tested. Most residential projects in Harriman are completed in 3–6 hours, with larger chimney or valley replacements taking up to one day.
How much does flashing repair cost in Harriman, and do you offer warranties?
Pricing depends on access, roof pitch, and the length of flashing needed. Small patch jobs start around $250, while full chimney or valley flashing replacements usually range from $600 to $1,200. All our flashing repairs include a 2-year workmanship warranty, and new flashing installations carry up to a 10-year material warranty when paired with our annual maintenance program.
