Formed on-site to fit your run, not cut to fit.
A “seamless” gutter is a gutter that runs the full length of the eave in a single continuous piece, with no horizontal joints between the corners. The way you get there is to bring the coil and the gutter machine to the job site, dial in the exact length the eave needs, and run that gutter out of the machine in one shot. That’s how we do it. Every run is measured at your house, rolled out of our gutter machine on-site, and hung the same day. The only joints are at the corners and the downspout outlets. The long runs themselves are seamless aluminum, formed cold. The result is a gutter that won’t leak at a mid-run seam (because there isn’t one) and that reads as a clean finish line along the eave instead of a stitched-together accessory. We do this statewide in Tucson, Phoenix, Sierra Vista, Sedona, Yuma, and anywhere our gutter rig can reach.
And color-matched.
The hero above is a brown K-style gutter on a Tucson home where the gutter, fascia, and corten privacy panels were spec’d to read as one earth-tone palette. That’s the move with metal: gutter, fascia cover, downspout, and roof panel can all share the same coating system, so the whole envelope reads as one finish instead of four separate accessories. Same baked-enamel and Kynar 500 color list as our roof and wall panels: pick once, match everywhere.
K-style vs half-round.
| Profile | Capacity | Aesthetic | Where it fits |
|---|---|---|---|
| 5” K-style | ~ 4,000 sqft drainage | Modern, slab-faced, reads flat from the street | Most Tucson and Phoenix residential |
| 6” K-style | ~ 7,000 sqft drainage | Same K profile, oversized | Steep-pitch roofs, large eave runs, monsoon-zone residential |
| 5” Half-round | ~ 3,500 sqft drainage | Classic, rounded, period-correct | Spanish revival, mid-century, historic remodels |
| 6” Half-round | ~ 6,000 sqft drainage | Oversized half-round, often in copper | High-end pueblo and Spanish-revival, copper specialty work |
The choice is partly drainage capacity, partly look. K-style reads modern. It’s the right pick for a snap-lock standing seam roof. Half-round reads classic, the right pick for a pueblo with hand-troweled stucco or a Spanish-revival with clay-tile accents. Both are formed on-site.

Sizing for Arizona rainfall.
Arizona looks dry on paper, and most of the year, it is. But monsoon rain isn’t year-of, it’s hour-of. A Tucson monsoon cell will drop 1.5-2.5 inches of rain in 30 minutes and a 5” K-style gutter at the wrong pitch will sheet water over the front lip the entire storm. So:
- 5” K-style is the right call for roofs draining ≤4,000 sqft per gutter run on slopes ≤6:12
- 6” K-style is required when the roof drains ≥4,000 sqft per run, or when the slope is ≥7:12 (steep-pitch roofs accelerate water and overshoot smaller gutters), or when you’re in a high-flash-flood neighborhood like the Catalina foothills, Oro Valley, or the Sierrita basin
- Downspouts are sized to the gutter. A 5” gutter pairs with a 2×3 downspout, a 6” gutter pairs with a 3×4 for monsoon throughput. We undersize neither.
If you’re not sure which you need, give us the roof footprint and slope on the call and we’ll size it.
Materials.
- .027 aluminum. The standard residential gauge, the right pick for most homes.
- .032 aluminum. Heavier-walled, dent-resistant, the right pick for tile-roof homes where service techs walk the gutter line, or for homes with mature mesquite that drop heavy debris into the gutters.
- 16-oz copper. Specialty option for high-end remodels and historic-revival projects. Patinas to a deep green-bronze in 5-8 years in Arizona’s dry climate.
- Downspout sizes: 2×3 (paired with 5”) and 3×4 (paired with 6”). Copper downspouts available in matching sizes
- Coatings: baked-enamel finish in 25+ standard colors. Kynar 500® PVDF upgrade for AZ’s high-UV south- and west-facing eaves. Mill-finish copper for the patina look
Rainwater harvesting integration.
Tucson Water customers can pair a gutter system with a rainwater harvesting cistern and earthworks to qualify for the Tucson Water rainwater harvesting rebate. Important to keep straight: the rebate is on the harvesting system itself (the cistern, the supply line, the earthworks, and the soil-prep), not on the gutters or the roof. The rebate program also requires the homeowner to take a free 3-hour Tucson Water rainwater harvesting workshop before the rebate is approved.
What our gutters do for you here is feed the cistern reliably: sized correctly for monsoon flow, located over the cistern inlet, screened against debris. We’ll work with whatever harvesting contractor or DIY plan you have. The full rebate breakdown lives on the residential page.
Pairs with.
- Materials, Colors & Wood-Grain Finishes. Color-match the gutter to the fascia or the roof.
- Metal Fascia Covers. Fascia and gutter usually go in together. Ask about the one-piece fascia + gutter wrap.
Warranty.
- Lifetime materials warranty on the aluminum (manufacturer-backed, covers substrate failure, not normal weathering)
- 45-year installation warranty when installed by a US-Metal-Roof-certified installer. DIY and 3rd-party-installer installs are covered by the materials warranty only.
