Why Gutter Cleaning Before Winter Matters More Than You Think

Hi, it’s Mike from Andover Pest Control. Every fall, I see the same thing across Andover‘s MA, and nearby Towns — homeowners getting ready for winter, checking the furnace, sealing the windows, and raking the yard. But there’s one simple job that doesn’t always make the list and skipping it can lead to some costly surprises later: gutter cleaning.

I get it — it’s not anyone’s favorite weekend project. But keeping your gutters clean does a lot more than just improve drainage. It protects your roof, siding, and foundation from damage. It also helps prevent ice dams, rotting fascia boards, and even pest infestations.

Let’s talk about why cleaning your gutters before winter might be one of the best decisions you make for your home this season.

1. Ice Dams Can Wreck More Than Your Roof

If you’ve ever seen long icicles hanging from a roofline, that’s usually a sign of an ice dam.
When your gutters are clogged with leaves and debris, melted snow can’t drain properly. It refreezes along the edge of the roof, forming a solid ridge of ice.

Once that happens, water gets trapped and starts working its way under your shingles, soaking insulation, drywall, and ceilings.
I’ve seen homeowners in North Andover MA deal with warped wood, peeling paint, and mold damage — all caused by clogged gutters.

A quick gutter cleaning before the freeze can help water flow freely and stop ice dams before they form.

2. Rotting Fascia Boards Invite Bigger Problems

Your fascia boards — the wooden planks right beneath your roofline — hold your gutters in place and protect your roof from moisture. When gutters overflow, that water sits on the fascia and slowly rots the wood.

Over time, that rotting creates soft spots, which can pull the gutters loose and leave gaps where rodents, squirrels, or carpenter ants sneak in. I’ve pressed my screwdriver straight through fascia that looked fine from the outside — it’s never good news.

Keeping gutters clean keeps those boards dry, strong, and pest-free.

3. Dirty Gutters Attract Pests

Clogged gutters are an open invitation for pests. All that damp leaf buildup creates the perfect nesting spot for ants, mosquitoes, and even mice.

In the colder months, rodents climb gutters looking for warmth and safety and once they’re close to your roofline, it’s an easy step into your attic through vents or soffits.

Keeping gutters clear helps keep pests far away from your home. It’s one of the simplest forms of pest prevention there is.

4. Protect Your Foundation and Siding, Too

When gutters overflow, water doesn’t just spill over the sides — it runs straight down your siding and pools around your foundation. That moisture can lead to cracked foundations, basement leaks, and mildew creeping up exterior walls.

By keeping your gutters clear, you’re protecting your entire home from top to bottom — roof, siding, and basement included.

5. Clean Gutters Help Prevent Mold and Mildew Indoors

Here’s another reason to keep your gutters clean: they help prevent mold and mildew inside your home.
When clogged gutters cause water to overflow or back up under the roofline, that moisture doesn’t just stay outside — it seeps into walls, ceilings, and insulation.

Once it’s trapped inside, mold and mildew start to grow, often before homeowners even notice it. You might see small dark spots on walls or ceilings, or start to smell that damp, musty odor that never seems to go away.

Regular gutter cleaning ensures rainwater drains properly and stays out of your home’s structure — keeping your attic, drywall, and insulation dry and mold-free.
