Gutters fail slowly, then all at once — usually in the middle of a March thaw. The good news: they telegraph their failure years in advance if you know what to look for. Here are the signs we check on every estimate across Metro Detroit, split into "repairable" and "replace it" — because more than half the calls we get labeled "replace my gutters" turn out to be honest repairs.
Walk-around checklist (10 minutes, from the ground)
- During rain: water sheeting over edges, leaking at seams or corners, downspouts trickling while gutters are full.
- Any dry day: sagging or wavy runs, gutters pulling off the fascia, visible rust streaks or orange peppering, peeling paint or dark stains on fascia boards, nails/screws on the ground below the eaves.
- At the foundation: trenched mulch, splash-back staining on brick, damp basement corners after storms — gutters failing quietly overhead.
Usually repairable
- One leaking seam or end cap on an otherwise sound system — reseal or replace the section.
- A pulled-loose section — re-hang with new hidden hangers, if the fascia behind it is still solid.
- Bad pitch in one run (standing water) — re-pitch.
- Crushed downspout or elbow — swap the piece.
Time to replace
- Rust-through anywhere. Older steel gutters rust from the inside; one visible hole means the metal is thin everywhere. (Common on original systems in Redford, Inkster, and Detroit's older blocks.)
- Leaks at multiple seams. Resealing every joint on aging sectional gutters is a subscription, not a fix — see why sectional joints fail here.
- Spike-and-ferrule fasteners working loose across the system — the fascia holes are wallowed out and re-driving spikes is temporary.
- Fascia rot behind the gutter. Soft, flaking wood means the gutter's been leaking behind itself for years — that's a fascia repair plus new gutters, done together.
- 20+ years old with recurring problems. Every service call is money toward a system with a 4-year warranty and none of these issues.

Why waiting costs more than acting
A failed gutter doesn't just cost you a gutter. Roof water concentrated at the foundation is the leading driver of wet basements; constant overflow rots fascia and soffit (a four-figure repair on top of the gutters); and winter turns marginal gutters into ice anchors that pry themselves off the house — the full mechanics are in our ice dam guide. The cheapest time to fix a gutter problem is the season you notice it. The costs for doing it right are in our Michigan pricing guide.
Frequently Asked Questions
How do I know if my gutters need to be replaced?
Replace when you see rust-through, leaks at multiple seams, spike fasteners working loose across the system, fascia rot behind the gutter, or a 20+ year old system with recurring problems. One bad seam or a single loose section is usually just a repair.
How long do gutters last in Michigan?
Seamless aluminum properly installed lasts 20–30+ years. Sectional systems typically need joint work within 3–7 years and replacement around 10–15. Old steel gutters on mid-century homes are almost always past their service life.
Can sagging gutters be fixed without replacing them?
Often, yes. If the gutter itself is sound and the fascia behind it is solid, a sagging run can be re-hung and re-pitched with new hidden hangers. If the fascia is rotted or the gutter is failing at multiple points, replacement is the honest answer.
