What Happens When Gutters Rust?

July 30, 2025by A P

Your gutters play a vital role in protecting your home from water damage. But over time, especially if they’re made of older materials or not well-maintained, rust can creep in and compromise their effectiveness. So what actually happens when your gutters get rusty… and how bad is too bad? Thankfully, at Noble Roofing, we know a lot about the problems that can happen to your home, especially when it comes to your roof and gutters.

Let’s dive into what you need to know before rusty gutters become a real headache.

Why It’s Not Good to Have Rusty Gutters

Rust is more than just an eyesore—it’s a sign of corrosion that can lead to serious damage. When gutters rust, they weaken. Eventually, holes form, leading to leaks that allow rainwater to spill over and damage your home’s siding, foundation, and landscaping.

Even worse, rusty gutters can clog more easily. Flakes of rust may break off and mix with leaves and debris, creating blockages that prevent proper water flow. This increases the risk of water backing up onto your roof or overflowing in the wrong direction.

How Rusted Is Too Rusted?

A little surface rust may not be the end of the world, especially if it’s caught early and treated with a rust-inhibiting primer and paint. But if your gutters are flaking, sagging, or you see visible holes, it’s likely beyond repair.

Here are a few signs your gutters are too rusted and need replacing:

  • Multiple holes or cracks

  • Rust that flakes off when touched

  • Water damage around your foundation

  • Gutters pulling away from the fascia

If you’re unsure, a professional inspection can give you a clear answer.

What Kind of Gutters Don’t Rust Easily?

If you’re replacing your gutters, consider rust-resistant options that offer longer lifespans and less maintenance:

  • Aluminum Gutters: Lightweight, affordable, and rustproof.

  • Vinyl Gutters: Won’t rust, but may crack in extreme temperatures.

  • Copper Gutters: Very durable and naturally corrosion-resistant (though more expensive).

  • Galvalume or Zinc-Coated Steel: Designed to resist rust for decades.

Each has its pros and cons, but any of these are better long-term choices than traditional galvanized steel without coating.

Is It Better to Go Cheap or Buy Nice Gutters?

When it comes to gutters, the saying “buy nice or buy twice” often rings true. Cheaper materials may seem like a good deal at first, but they’re more likely to rust, sag, or fail sooner—leading to more repairs and potential home damage.

Higher-quality gutters may cost more upfront, but they last longer, require less maintenance, and give you peace of mind during storms. And when installed by a reputable roofing company, you get warranties and professional support, too.
