Most Charleston homes need their gutters cleaned at least twice a year: once in spring after the live oaks drop their old leaves, and once in late fall after the pines and hardwoods shed. Homes under heavy tree cover often need three or four cleanings a year.
That answer surprises people who moved here from somewhere with one big fall leaf drop. The Lowcountry has two shedding seasons, plus summer storms that wash shingle grit and pollen into everything in between.
The two times of year that matter most
Spring (April to May). Live oaks are evergreen, but they push out their old leaves when the new ones come in each spring. Add oak catkins and pollen, and gutters under live oaks can be packed by May.
Late fall (November to December). Pines drop needles heavily in fall, and hardwoods like sweetgums, maples, and water oaks lose their leaves. A cleaning after the drop gets you through winter rains.
If you only do two cleanings, time them for after those drops, not before. Cleaning in March just means doing it again in May.
What changes the answer for your house
- Trees over the roof. Pines are the worst for clogs because needles mat together into a dam. One big pine over the house can mean three or four cleanings a year.
- Roof shape. Valleys collect debris and dump it into one spot, so homes with lots of valleys clog faster.
- Gutter size. Small 5 inch gutters clog sooner than 6 inch gutters with oversized downspouts.
- Gutter guards. The right guard can cut cleanings down to a quick check every year or two.
Signs your gutters are overdue
- Water spills over the front edge during an ordinary rain
- Plants, moss, or seedlings growing in the gutters
- Downspouts that barely trickle in a storm
- Gutters sagging or pulling away from the fascia
- Dark streaks on the siding below the gutters
- Mosquitoes hanging around the roofline in summer
Why skipping cleanings costs more later
A clogged gutter does not just overflow. Water backs up behind it and soaks the fascia board, which rots, and then the gutter has nothing solid to hang on. Overflow also lands right next to your foundation, where it can wash out beds, stain brick, and add moisture to a crawl space.
Compared with replacing rotted fascia or fixing drainage problems, two cleanings a year is cheap insurance.
Should you clean your own gutters?
On a single-story home with a stable ladder and a helper, plenty of homeowners do. On two and three-story homes, steep roofs, or anything near power lines, it is worth calling a pro. Ladder falls are a common cause of serious injuries at home.
GutterWorks cleanings include hand-clearing every gutter, flushing every downspout, a check of hangers and fascia, and before and after photos. See gutter cleaning and maintenance plans.
