Measure the total run in linear feet, multiply by a per foot rate for the material you want, then add the downspouts, the corners and any fascia repair. That gives a working estimate you can hold a real quote up against. It will not replace a site visit, but it tells you fast whether a number is in the right country.
Gutter Answers connects you with licensed local companies. We are not a contractor and do not perform the work ourselves.
Use the middle of the band for your material, then adjust for access.
| Material | Rate to estimate with |
|---|---|
| Vinyl, sectional | $4 to $6 per linear foot |
| Aluminum, seamless | $6 to $13 per linear foot |
| Galvanized steel | $9 to $20 per linear foot |
| Copper | $25 to $45 per linear foot |
Add roughly 5 to 12 dollars per foot of downspout, and a small allowance per corner. For what each of those lines actually includes, see what drives a gutter quote.
Take a single story house with 150 linear feet of gutter and four downspouts of about 20 feet each.
The fascia is the wildcard, since it cannot be judged from the ground.
Because a calculator cannot see your fascia, your roof access or the way water actually leaves your roof, and those are exactly where quotes diverge. Treat the estimate as a sanity check, not a bid.
To see how the install is actually carried out, read how the work is sequenced.
Measure the run in linear feet, multiply by a per foot rate for your material, then add downspouts, corners and a fascia allowance for a working figure.
A typical single story home has roughly 150 to 200 linear feet. Measure each roof edge that carries a gutter and add them for your own total.
Roughly 5 to 12 dollars per foot of downspout, or on the order of 50 to 150 dollars each installed, more where water is carried away underground.
It estimates length and material well enough to sanity check a quote. It cannot see access or fascia condition, so it will not match a real bid exactly.
