The generic internet answer is "twice a year." Under Metro Detroit's mature maples and oaks, that answer costs people fascia boards, foundation grading, and the occasional basement. Here's the schedule we actually recommend to customers, based on what your street looks like — plus the calendar quirks (maple seeds in June, oak drop in November) that generic advice misses.
The schedule, by tree cover
| Your street | Cleanings per year | When |
|---|---|---|
| Heavy canopy (mature maples/oaks overhead) | 3–4 | Late spring, mid-fall, after leaf drop, spring check |
| Moderate (trees nearby, not overhead) | 2 | Late spring + after leaf drop |
| Light (young trees, open lot) | 1 | After leaf drop |
| Pines overhead | 3–4 | Needles shed year-round and mat instantly |
Michigan's calendar, decoded
- Late May–June: maple seed drop. The "helicopters" from Metro Detroit's silver maples mat into a dense sheet in gutters — and they germinate there. If you've seen seedlings sprouting from a gutter in Livonia or Redford, this is why. Clean after the drop finishes.
- June: cottonwood fluff. Along Hines Park and the Rouge corridors, cottonwood coats screens and cheap guards.
- Mid-October–November: the main event. Don't clean at first leaf fall — you'll be doing it again in three weeks. Wait until your street's trees are mostly bare, then clean before the first hard freeze so gutters don't go into winter loaded. Oaks hang on latest; oak streets clean into late November.
- Winter: eyes only. Watch for icicles at the gutter line — an early sign of clogs or the attic-heat problems covered in our ice dam guide.
Signs you've waited too long
- Water sheeting over the gutter edge in rain
- Plants growing in the gutter
- Sagging runs (wet debris is heavy — 100 feet can hold 300+ lbs)
- Staining or peeling paint on the fascia behind the gutter
- Mulch splash-out and soil erosion below the eaves
- Damp basement corners after storms
The last three mean water has been going where it shouldn't for a while. Overflowing gutters dump roof water at the foundation — a single inch of rain on an average roof is over a thousand gallons. If the fascia is soft or the gutter has pulled loose, cleaning won't fix it; that's repair or fascia work territory.
DIY safely or don't DIY
- Ladder on firm, level ground with a standoff stabilizer — never leaned on the gutter itself (that's how gutters bend and people fall).
- Keep your hips between the rails; move the ladder often.
- Scoop, then flush toward the downspout with a hose.
- Flush each downspout and watch it exit — a downspout clog just moves the overflow.
- Two-story homes: hire it out. Ladder falls from second-story height are life-changing. $150 is cheap.
Done with the ladder ritual? Quality micro-mesh guards cut cleaning to nearly zero — our honest guard breakdown covers when they pay off and when they don't.

Frequently Asked Questions
How often should gutters be cleaned in Michigan?
Under heavy tree cover — common across Metro Detroit — 3 to 4 times a year: after maple seed drop in late spring, mid-fall, after full leaf drop before freeze-up, and a spring check. Homes with light tree cover can get away with once a year after leaf drop.
When is the best time to clean gutters in the fall?
After your street's trees are mostly bare but before the first hard freeze — usually late October to late November in Southeast Michigan, later on oak-lined streets. Cleaning at first leaf fall means doing it twice.
What happens if I don't clean my gutters?
Clogged gutters overflow at the foundation (an inch of rain on an average roof is over a thousand gallons), rot the fascia boards behind them, sag under debris weight, and give winter ice a head start. Most of the fascia rot we repair started as a neglected clog.
