Seamless Gutter Installation in Northeast Florida: 6, 7, and 8-Inch K-Style, Box, and Half-Round

For most Jacksonville homes, a 6-inch K-style seamless gutter is the right size. Larger custom homes, steep architectural rooflines, metal roofs, clay tile roofs, and high-volume roof valleys typically need 7-inch K-style. Very large homes, commercial buildings, and box-gutter applications can require 8-inch. Gutter Pro does not install 5-inch gutters in Northeast Florida because they overflow in Florida's high-volume rain events. Your free on-site quote includes a roof-area calculation that sizes the system to actual rainfall load.

Gutter Pro installs 6-inch, 7-inch, and 8-inch seamless gutters. K-style is available in all three sizes. Box gutter is available in 7-inch and 8-inch. Half-round is available in 6-inch and 8-inch. We fabricate in commercial-grade aluminum, galvalume, and 16 oz solid copper. We do not install 5-inch gutters because they are undersized for Northeast Florida rainfall and for the heavy roof areas typical of larger homes here.

A 3-by-4-inch rectangular downspout pairs with 6-inch K-style on most Northeast Florida homes. A 4-by-5-inch oversized rectangular downspout is required for 7-inch and 8-inch gutters or any high-volume run. A 4-inch round downspout pairs with half-round gutters and copper systems. Undersized downspouts are the most common reason for "the gutters overflow" complaints. Gutter Pro sizes downspouts to the actual flow off your roof, not to the builder default.

Yes. Seamless gutters are custom-fabricated on site from a single piece of aluminum or copper to match your roofline exactly, which eliminates the joints in the middle of each run where sectional gutters typically leak. Fewer seams means fewer failure points, longer service life, and a cleaner appearance. Every gutter Gutter Pro installs is seamless, rolled to length on our truck-mounted machine.

Gutter Pro installs Alu-Rex T-Rex hidden hangers spaced every 18 inches, screwed directly into the fascia board. Hidden hangers hold significantly more weight per foot than spike-and-ferrule, do not back out under thermal cycling, and look clean from the curb. Spike-and-ferrule is 1950s technology that some competitors still use because it is faster to install. We will not specify it on a Gutter Pro install.

Most residential seamless gutter installations are completed in a single day. Larger estate-scale homes, complex multi-story rooflines, or projects that include underground drainage typically take two to four working days. Your on-site quote includes a realistic timeline before any work starts, and the crew texts you at arrival, key milestones, and completion.

No. You do not need to be home during the install once the design and color are approved. Most homeowners are at work. The crew texts you when they arrive, when major milestones are complete, and when the magnetic sweep for screws and nails is finished. Owner Albert is on site for the design walk and any judgment calls during install.

Yes. Old gutters are removed, hauled away, and disposed of the same day, included in every install. Soffit, fascia, or drainage components are removed only if you have approved that work in advance. We never leave debris in the driveway overnight. A magnetic sweep of the jobsite finishes every project.

Yes. Gutters collect roof runoff and move it away from the home before it can pool against the foundation, erode mulch beds, or seep into a crawlspace. The combined system of properly sized seamless gutters, correctly placed downspouts, and underground drainage to a safe discharge point is what actually protects the foundation. As NDS Certified Professional Drainage Contractors, Gutter Pro designs the full water path, not just the trough.

Gutter guards are optional but strongly recommended for homes under heavy live oak or pine canopy, and required for any home where downspouts connect to underground drainage. LeafBlaster Pro stainless steel micromesh is rated for both oak leaves and pine needles and carries a 40-year manufacturer warranty. Alu-Rex Double-Pro adds structural reinforcement to the gutter itself, ideal for high-volume runs. Gutter Pro is an authorized installer for both.

Yes. Gutter Pro connects downspouts to underground drainage, catch basins, French drains, channel drains, dry wells, and pop-up emitters as part of a complete water-management system. All underground drainage is installed in Schedule 40 PVC, never corrugated black pipe. Corrugated pipe collapses, silts up, and grows roots within a few seasons in Florida soil. Schedule 40 lasts decades.

Gutter Pro offers a lifetime workmanship warranty on every install. If a seam, corner, hanger, or downspout we installed fails, we fix it at no cost to the original homeowner. Manufacturer warranties cover the materials themselves: up to 50 years on LeafBlaster Pro gutter guards, baked-on enamel finishes on aluminum, and solid copper components. The full warranty terms are documented in writing on every project.
