When an Ann Arbor home needs new gutters installed
Installation means putting gutter where there is none, or redesigning the system rather than swapping like for like. That is different from replacement, and it comes up in Ann Arbor for a few common reasons.
- An addition, porch or rear elevation that never had gutter, dumping water at the foundation.
- A detached garage draining onto the drive or the neighbour's yard.
- After a re-roof, when new drip edge changes how water leaves the roof.
- Resizing for tree cover — stepping up to 6-inch trough because the old system clogs every few weeks.
- Adding a rain garden, where downspouts need to move to feed it.
If gutter is already hanging and the plan is to replace it with something similar, read the Ann Arbor gutter replacement page instead.
Sizing for Ann Arbor's tree cover
Gutter size is a drainage calculation based on roof area, roof pitch and how hard rain falls. In Ann Arbor, there is a fourth factor that often matters most: how much falls out of the trees.
| Spec | 5-inch K-style + 2x3 downspout | 6-inch K-style + 3x4 downspout |
|---|---|---|
| Relative trough capacity | Baseline | Roughly 40% more |
| Downspout cross-section | 6 sq in | 12 sq in — about double |
| Clog resistance | Oak leaves and maple seed plug the outlet readily | Passes far more debris before blocking |
| Typical Ann Arbor fit | Ranches and smaller homes with few trees | Homes under oak and maple, steep roofs, long runs |
| Installed cost | $9 – $15 / ft | $12 – $19 / ft |
The practical Ann Arbor rule: if a mature oak or maple hangs over the roof, the extra cost of 6-inch and 3x4 downspouts usually pays for itself in fewer clogs and fewer overflow-soaked fascia boards.
Matching the gutter to the house
Historic homes
The Old West Side, Old Fourth Ward, Division Street and Broadway areas include homes from the mid-1800s onward. Many originally had half-round gutters, and some had box gutters built into the cornice. In a local historic district, the Historic District Commission reviews exterior changes, and half-round or copper may be what fits.
Early 20th-century homes
Burns Park, Eberwhite and similar neighbourhoods have four-squares, bungalows and Craftsman homes. Seamless K-style or half-round both work, and colour matching to the trim makes a big difference to how the gutter reads from the street.
Mid-century modern homes
Ann Arbor has a large stock of mid-century modern homes, many in Ann Arbor Hills. Low slopes and wide overhangs drain slowly, and some roofs use scuppers or internal drains. A slim box or fascia-style profile usually keeps the look; standard K-style can look heavy.
Post-war ranches and newer homes
Lansdowne, Bryant and much of the south and west sides have simpler rooflines where standard seamless aluminum is the sensible choice.
Materials
- Seamless aluminum — roll-formed on site, joints only at corners, no rust, wide colour range. Choose .032 gauge for strength.
- Galvanized or galvalume steel — stronger and heavier, sectional, and will eventually corrode at cut edges.
- Copper — soldered joints, lasts for decades, commonly $32 to $60 per foot and up. Often the right answer on historic homes.
How a gutter installation goes
- Measure and assess. Every run measured, trees and roof valleys noted, fascia probed, and downspout and rain garden locations planned.
- Fascia and drip edge prepared. Soft board replaced. A gutter apron or drip edge fitted so water goes into the trough, not behind it.
- Gutter roll-formed on site to the exact length of each run.
- Hung on hidden hangers with screws, typically 24 inches apart and tighter on long runs.
- Pitched to the outlets — about a quarter inch of fall per ten feet.
- Downspouts hung and strapped, with extensions or piping to a rain garden or the lawn.
- Water tested, then clean-up and haul-away.
Gutter installation cost in Ann Arbor
Typical Ann Arbor ranges, not quotes.
| Line item | Typical Ann Arbor range | Notes |
|---|---|---|
| 5" seamless aluminum, installed | $9 – $15 / ft | Gauge, colour and corner count move this |
| 6" seamless aluminum, installed | $12 – $19 / ft | Includes 3x4 downspouts |
| Box or fascia-style profile | $14 – $24 / ft | Common on mid-century modern homes |
| Copper half-round | $32 – $60+ / ft | Historic homes; material prices swing |
| Downspout, per drop | $75 – $190 | Height and elbows |
| Extension or piping to rain garden | $150 – $600+ | Distance and whether it is buried |
| Fascia replacement | $12 – $28 / ft | Common under heavy canopy |
Worked example. An Ann Arbor bungalow with 140 feet of run, four downspouts and 6-inch aluminum, no fascia work: roughly $1,900 to $3,000. The same house in 5-inch: roughly $1,500 to $2,400.
Where the water goes
The point of a gutter is getting water past the foundation. The Michigan Residential Code calls for grading that falls away from the foundation — on the order of six inches within the first ten feet — and a downspout at the wall works against it.
In Ann Arbor, the best answers are extensions onto the lawn or a rain garden well away from the house. Roof water should never go into the sanitary sewer — the city has spent years disconnecting clear water from it to cut basement backups.
