How often should you clean your gutters (and what happens if you don't)

I'm writing this on a lunch break, still a little annoyed, because I just watched a neighbor's downspout during this morning's rain do absolutely nothing — water sheeting straight over the lip of a clogged gutter and pouring down the corner of the house, right where you least want it. He'll pay for that eventually. Most people who skip gutters do.

Gutters are the least glamorous thing on your house and one of the most important. Their entire job is to catch the rain off a big sloped roof and route it away from the one place water must never collect: the foundation. When they clog, they don't just stop working — they actively make things worse. So let's talk about how often to actually clean them.

The baseline: twice a year

For most homes, the rule is twice a year — once in late spring and once in the fall, after the leaves have finished dropping. That fall cleaning is the important one; a gutter packed with wet leaves going into winter is asking for trouble.

But "twice a year" is the baseline, not the law. The real driver is how many trees hang over your roof.

A quick way to calibrate for your own house:

• Few or no overhanging trees: twice a year is plenty.
• Some trees nearby: spring, mid-fall, and late fall — three times.
• Roof under heavy tree cover: check every couple of months in the growing and dropping seasons.

What actually happens when you don't

This is the part people underestimate, so let me be specific. A clogged gutter overflows, and that water has to go somewhere. Over a season or two it finds every one of these:

• The foundation. Water pooling against the base of the house is the number-one cause of foundation problems and wet basements. Cracks, seepage, and eventually settling — the most expensive repairs a house can hand you, all starting from a gutter.
• The roof and fascia. Water backing up sits against the roof edge and the wooden fascia board behind the gutter, and rots it. In winter that standing water helps form ice dams that push up under the shingles.
• The siding and exterior. Overflow streaming down the wall stains it, rots trim, and works its way behind the cladding.
• The gutters themselves. A trough full of wet debris is heavy — heavy enough to sag, pull its fasteners out of the fascia, and rip clean off the house.
• Everything that likes standing water. Mosquitoes breed in it; pests and even little rooftop gardens of weeds move in.

None of that is dramatic on any given day. That's exactly why it's dangerous — it's slow, invisible, and by the time you see the damage it's a four-figure repair instead of an afternoon on a ladder.

Doing it yourself, safely

If it's a single-story house and you're comfortable on a ladder, this is a very doable Saturday job:

• Use a sturdy extension ladder on firm, level ground, and don't lean it against the gutter itself. Ideally have someone foot the ladder for you.
• Wear gloves — you'll be scooping wet, gritty muck and occasionally something that used to be alive.
• Scoop the debris out by hand into a bucket, working from the downspout outward.
• Then flush the gutters with a hose to move the fine grit and check the flow.
• Test the downspouts. Run water and make sure it comes out the bottom with force. If it trickles, there's a clog in the downspout — tap it or run the hose up from the bottom to clear it.
• While you're up there, make sure downspouts discharge at least a few feet from the foundation. An extender is a cheap fix that prevents the worst problem on this whole list.

Two stories, a steep roof, or any nervousness about heights? Hire it out. Gutter cleaning is inexpensive as home services go, and it is genuinely not worth a fall.

The trap is forgetting, not the work

Here's the thing about a twice-a-year job: it's just infrequent enough to slip your mind entirely. Spring cleaning gets swallowed by everything else spring throws at you, and by the time you remember in fall, it's raining.

I finally stopped playing that game by letting BillPup track it — it knows my house has a couple of maples over the roof, so it nudges me in spring and twice in fall instead of the generic twice. Whatever tool you use, the move is the same: anchor gutter cleaning to the calendar, not to the moment you happen to glance up during a storm and notice the water going the wrong way.

Because by then, like my neighbor this morning, you're already paying for it.
