Materials & Types
The materials & types cluster: a material cost & lifespan compare (aluminum / copper / steel / vinyl, cost per year), a K-style vs half-round capacity compare, a 5" vs 6" capacity & cost compare, a seamless vs sectional compare, and a gutter gauge / thickness reference. Capacity figures are labeled planning values — confirm local rainfall and code.
Planning estimate: this is a planning estimate from the numbers you enter — not a bid or a contract. Gutter pricing depends on material, size, linear feet, guards, fascia condition, removal, height/access and local labor. Get itemized written quotes from licensed, insured gutter contractors before you commit.
Typical published planning values — NOT a certified design. Actual gutter sizing depends on local rainfall intensity, roof geometry, valleys and debris; follow local code and the manufacturer’s data, and consult a pro for complex roofs. Structural roof-load, ice-dam / heat-cable and foundation/yard drainage are set by code and a professional — not engineered here.
Material cost & lifespan compareCompare aluminum, copper and vinyl gutters on installed cost and cost per year over their service life, from your own prices and labeled lifespan bands.K-style vs half-round capacitySee the smallest K-style and smallest half-round gutter that drains your effective roof area at a given rainfall intensity, with a labeled capacity table.5" vs 6" gutter capacityCompare 5-inch and 6-inch K-style gutter capacity at your rainfall intensity and see the extra cost of stepping up to 6-inch over your linear feet.Seamless vs sectional compareCompare seamless and sectional gutters on section count, leak-prone joints and installed cost from your own per-foot prices, over any run length.Gutter gauge / thickness referenceLook up aluminum gutter gauges — economy .019, standard .027 and heavy .032 inch — and where each thickness makes sense for runs and snow load.
Every Materials & Types tool is calculated server-side — visible immediately — with its formula, a worked example and a reference table, and works on the measurements you take and the prices you enter from your own quotes. Background reading is in the guides.
