FAQs
What is chimney flashing and why is it especially important in Chattanooga?
Chimney flashing is the sheet-metal barrier (usually aluminum, galvanized steel, or copper) that seals the intersection where your chimney meets the roof. Chattanooga averages more than 50 inches of rain a year, along with frequent freeze-thaw cycles in winter. Without a watertight flashing system, water can wick under shingles, rot roof decking, and leak into walls and ceilings. Properly installed custom flashing directs rain, melting snow, and condensation away from this vulnerable joint, protecting both the roofing system and the masonry in our moisture-prone climate.
How can I tell if my current chimney flashing needs repair or replacement?
Warning signs include rust stains on the chimney or roof, loose or missing step flashing pieces, dried or cracked sealant, water spots on ceiling drywall near the chimney, musty odors in the attic, or masonry efflorescence. During storms you might notice drips or damp insulation in the attic around the chimney stack. Because some damage is hidden, we recommend a professional inspection every 2–3 years—or immediately after severe weather events such as the strong thunderstorms common to the Tennessee Valley.
What makes custom chimney flashing different from prefabricated flashing kits?
Off-the-shelf kits come in fixed sizes and generic angles. Custom flashing is field-fabricated to match the exact pitch of your roof, the dimensions of your chimney, and any irregular masonry contours. We use portable metal brakes to bend step, counter, and apron pieces on-site, ensuring continuous overlaps, precise soldered or riveted seams, and a profile that tucks neatly into mortar joints. The result is a cleaner look, superior water diversion, and a lifespan that typically outlasts the surrounding shingles.
Which flashing materials hold up best in Chattanooga’s weather?
• Aluminum: Lightweight and economical but prone to galvanic corrosion if it contacts copper gutters or certain treated lumbers. • Galvanized steel: Strong and affordable; however, our humid conditions can shorten its service life unless it’s factory-painted. • Copper: Premium option that can last 60+ years. It forms a protective patina that resists Chattanooga’s high rainfall and humidity. • Stainless steel: Extremely durable and often chosen when copper aesthetics aren’t desired. We recommend copper or stainless for long-term performance, especially on high-end or steep-slope roofs, and aluminum for budget projects with compatible materials.
How long does a custom chimney flashing installation take, and will it disrupt my household?
Most residential jobs are completed in a single day: 1–2 hours for setup and roof protection, 2–4 hours for removing old flashing and shingles around the chimney, 1–3 hours to craft and install new step and counter flashing, and another hour to replace shingles and perform a water-penetration test. You do not need to vacate the home. We keep debris contained, use magnetic sweepers for nails, and finish with a full cleanup so your yard and driveway are safe by the time we leave.
Do you offer warranties, and will new flashing affect my insurance or resale value?
Yes. Our company provides a 10-year workmanship warranty on custom flashing plus the manufacturer’s material warranty—up to 50 years for copper. Because flashing is a critical waterproofing component, many insurers require it to be in good condition; upgrading can help you avoid claims or even lower premiums. Real-estate inspectors flag faulty flashing as a defect, so investing in a documented, professionally installed system can add value and expedite closing when you decide to sell your Chattanooga home.
