Seamless aluminum gutters and downspouts typically last 20-30 years and cost $6-$15 per linear foot installed at 2026 national prices. Material drives the range — aluminum is the multifamily standard, galvanized steel costs slightly more, and copper can triple the price but last 50+ years. Building height and roofline complexity are the main labor variables.

Quantify by measuring total roof-edge linear footage per building and add downspout drops (roughly $50-$240 each) — reserve studies that count only horizontal runs understate the project by 15-25%. Replacement is usually scheduled alongside or just after roof replacement so staging and access costs are shared.
Clean gutters at least twice a year (quarterly under heavy tree cover), reseal end caps and outlets, and re-secure loose hangers so standing water never overtops the back edge into fascia. Gutter guards and annual downspout flushing extend service life and protect the more expensive fascia, siding, and foundation components downstream.
Snow-country installations need heavier-gauge material and snow guards that raise cost, while coastal salt air and heavy tree cover shorten aluminum gutter life toward the 20-year floor.

Set-aside = replacement cost ÷ useful life (20–30 years). A new installation funds toward the long end; an aging one needs catch-up funding — run the full calculator for that.
