FAQs
Why are high-capacity gutter systems important in the Knoxville climate?
Knoxville receives more than 50 inches of rain each year and experiences sudden, heavy downpours in spring and summer storms. Standard 5-inch gutters can overflow during these events, allowing water to back up under shingles, erode landscaping, and damage foundations. A high-capacity system—typically 6-inch K-style or 7-inch box gutters with oversized downspouts—moves up to 40 % more water, protecting your roof, siding, and basement from costly water intrusion.
What materials do you recommend for durable, high-capacity gutters?
We primarily install heavy-gauge (.032″) aluminum and 24-gauge galvanized or galvalume steel for residential projects, because both handle large volumes without sagging and resist Knoxville’s humidity. For premium applications, we offer 16-ounce copper or Kynar-coated steel, which deliver 50-year life spans and superior curb appeal. All materials are seamless and formed on-site to exact lengths to minimize leak points.
How does your team determine the right gutter size and capacity for my roof?
During the inspection we measure roof area, slope, and valley concentration points to calculate peak runoff (in gallons per minute). We then reference NRCA and SMACNA sizing charts to choose the gutter width, depth, and downspout dimensions that will safely carry that volume plus a 20 % safety factor. We also evaluate fascia condition, roof pitch, and drainage paths before recommending 6-inch K-style, 7-inch box, or specialty half-round profiles.
Will replacing my gutters damage my existing roof or fascia boards?
No. We remove old gutters with pry bars that protect shingles and flashing. Any deteriorated fascia is replaced or reinforced before new hangers are installed. Our hidden-strap hanger system screws directly into rafter tails, reducing uplift and eliminating the need to lift shingles. All jobs finish with a magnetic nail sweep and full debris cleanup, leaving your roof and landscaping intact.
What is the typical timeline and cost range for a high-capacity gutter replacement in Knoxville?
Most residential projects (150–250 linear feet) are completed in one day, weather permitting. Larger homes or systems requiring fascia repair may take two days. Pricing averages $12–$20 per linear foot for 6-inch seamless aluminum, including removal of old gutters, new downspouts, and leaf guards. Steel or copper upgrades range from $20 to $40 per foot. After an on-site assessment, we provide a fixed, written estimate good for 30 days.
Do you offer warranties and maintenance services for new high-capacity gutter systems?
Yes. Our installations include a 5-year workmanship warranty plus a 20- to 50-year manufacturer material warranty, depending on the metal selected. Optional annual maintenance plans cover cleaning, resealing end caps, and adjusting hangers to preserve your warranty and ensure optimal flow. Customers on our plan receive priority scheduling and discounted repairs after severe weather events common to the Knoxville area.
