Rusting Gutters: Causes, Signs, and Prevention

Gutters are a type of drainage system that carries rainwater away from the roof of your house and prevents it from reaching the property’s foundation. However, this makes them prone to severe wear and strain. They are particularly susceptible to rust and corrosion, which can cause damage. Rust can clog gutters and endanger your home.

Rusting gutters are a big problem for homeowners. It not only makes your property look unkempt, but it can cause significant problems if left ignored. In this article, we will explain what rusting is, what the signs are, how to spot the symptoms, and—most importantly—what is the prevention of rusting.

What is Rusting and When Does it Happen?

This natural phenomenon occurs when metal comes into contact with oxygen and water. As a result, the metal deteriorates and creates a reddish-brown covering known as rust. When gutters are exposed to rainwater regularly, the metal rusts because the water, including minerals and oxygen, accelerates the process.

Common Causes of Rusting

The gutters form rust because water is not drained properly or water pools are inside. The cause can be unprofessional installation, pollution, incorrect slope angle, etc. Here are some of the other main factors contributing to the occurrence of rust:

  • Moisture: Rain and snowmelt accumulating in gutters create the perfect conditions for rust to form and grow.
  • Debris: Twigs, leaves, and other materials inside the gutters may hold moisture and cause corrosion.
  • Poor drainage: It’s more difficult for water to drain if the gutters are improperly built or clogged. This increases the risk of rusting.
  • Oxygen: The presence of oxygen in the air speeds up the oxidation process, resulting in the development of rust.

Recognizing Signs of Rusting Gutters

There are a couple of visible signs that you need to watch out for to prevent further deterioration.

  • Discolouration: Rust frequently appears as reddish or brownish streaks on the surface of the gutters.
  • Flaking or peeling paint: If your gutters are painted, rust may be the reason for the paint to bubble, peel, or flake.
  • Rough texture: Rust can make the surface of the gutters seem rough or pitted.

If you don’t repair your rusted gutters, they can cause various problems. Some of them are structural damage, water leaks,  and clogging. On the first occasion, rust undermines the structural integrity of the gutters as it consumes the metal, possibly causing them to sag, break, or collapse. On the second one, rust may cause holes or gaps in gutters, causing water leaks. 

When you notice your gutters are clogged, remember that rust can be one of the reasons for that because it contributes to debris accumulation. Overflowing water from clogged gutters may ruin the roof.

Preventing Rusting on Gutter and Maintenance Tips

To preserve the integrity of your property, you have to prevent gutter rust by following several tips and treatments. Check out some of the preventative actions you could take to avoid rust on your gutters:

  • Regular cleaning: This is one of the most important factors that are very helpful for the excellent condition of the gutters. Clean out your gutters frequently to avoid moisture buildup and lower the chance of corrosion.

  • Adequate drainage: Ensure your gutters are correctly installed and that water can easily flow through them. This will reduce water accumulation and decrease the risk of rust formation.
  • Trim the nearby trees: To prevent leaves and twigs from falling into your gutters and clogging them, trim tree branches that hang over the gutters.
  • Inspection: Periodically check your gutters for any damage, including rust. Any problems should be resolved at once to avoid potential deterioration.
  • Repair and repaint: If you spot rust, clean the afflicted parts, apply a rust-inhibiting primer, and then repaint them. Putting a layer of protection on your gutters can help stop corrosion.

Keep in mind that even with protective coatings or treatments, regular cleaning, maintenance, and inspections are still required. Due to the chance that these coatings can wear off or get damaged over time, it’s essential to keep an eye on the status of your gutters and reapply preventive measures as needed.
