Aluminum vs copper seamless gutters: what each costs on a West Virginia home

A crew truck with a roll-forming machine pulls into the driveway, and that machine is really the whole story of seamless gutters. Aluminum or copper, the process on installation day looks almost identical — the material fed through the machine is what changes the price tag by a wide margin. Here’s what actually happens from the driveway to the downspout, and where the cost difference between the two metals comes from at each stage.

Measuring the roofline and pricing the job

Before any metal gets cut, someone walks the roofline with a tape measure and notes the linear footage, the number of corners, the roof pitch, and where the downspouts need to land based on drainage. This is also when the material choice gets locked in, because aluminum and copper price out completely differently per foot.

Aluminum coil stock runs a few dollars a linear foot before labor. Copper coil can run several times that, sometimes five to eight times the raw material cost of aluminum, before a single piece is hung. On a typical Morgantown home with 150 to 200 feet of gutter run, that difference alone can separate a job by thousands of dollars. Older homes around Suncrest or South Park with more roof lines, dormers, and valleys need more linear footage and more corners, which multiplies the gap between the two metals rather than closing it.

Loading the coil into the roll-forming machine

Once the linear footage is set, the coil — aluminum or copper — gets loaded into the roll-forming machine parked at the house. This machine bends flat metal coil into a K-style or half-round gutter profile in one continuous piece, cut to the exact length needed for each run. That’s the
