Can You Repair Rusted Gutters?

August 05, 2022

Rain gutters are known to be resistant to almost anything. Metal gutters are durable enough to stand the worst storms without losing any of their esthetic appeals. Sadly, this doesn't mean that they're indestructible, and rust is the main proof of this. Without intervention from a Rain Gutter Repair Service, a rusted gutter can leak and lose all its strength, which is why regular inspections can really make a difference. If you're at a loss when it comes to repairing rusted gutters, we tell you all you need to know.

Does Your Gutter Have Rusting Problems?

Unfortunately, rust is a risk that all metal gutters have to face. It results from the interaction of metal, oxygen, and moisture, so it's impossible to avoid. On top of holding large amounts of water during a storm, rain gutters are always exposed to various temperatures and environmental changes. Sometimes, you don't even need to get rain to trigger rust on your gutters; dew or fog can also work as conductors. There are many ways to slow down the effects of rust, but metal gutters remain vulnerable to it through all their lifespans.

While aluminum and galvanized steel are known for their longstanding resistance to rusting, they can still succumb to it sooner or later depending on environmental conditions and the owner's maintenance habits. For galvanized steel, the risk increases as the gutter's zinc coating begin to wear off.

This doesn't mean that you should expect any rusting for a long time. Rusted spots are fairly rare on custom gutters since they're made of high-quality materials that are meant to look whole for decades without affecting the gutter's capacity.

Causes of Rusted Gutters

We've already outlined the general conditions that onset a rusting problem. Still, you can minimize the impact that continued exposure leaves on rain gutters by paying attention to certain elements.

• The gutter's lifespan: New, high-quality materials will always fare better than old metals. Rust is often associated with old gutters, particularly due to the rundown appearance it brings to the forefront. In extreme cases, it can make a gutter look on the brink of collapse, and this should be a hint for you to get a new, more resistant guttering system. An old gutter lacks stability, on top of making your whole property look shabby.


• Temperature fluctuations: If you live in a tropical area, you're probably familiar with the way a sudden temperature change can cause certain materials to contract and expand. In Miami and its surroundings, local temperatures can rise or fall in very drastic ways, sometimes more than once on the same day. Since you can't move your property to a different location, the best approach is to keep an eye on your gutters to monitor how it responds to each of these changes.


• Gutter maintenance: To catch any rusted spots early on, regular maintenance is key. If you don't look after your gutters properly, rust will be one of the most evident signs of neglect. A professional cleaning service will be quick to catch any problem no matter how small, so you can preserve the material for much longer.


• The gutter's reaction to other metals: If your guttering system involves more than one type of metal, you may trigger corrosion early on. The water running along the gutter's length will act as a conductor and accelerate the process. You can discuss your material preferences with your contractor to check which metals are safe to use in each situation.


• Exposure to acidic elements: Tree pollen and other organic elements have acidic properties that could wreak havoc on your gutters after resting on their metal surface for too long. This is why it's so important to flush out any leaves, twigs, and plant particles that make their way to your roof.

How To Deal with Rusted Gutters

If you find rust spots, you can use a wire brush or sandpaper to scrub away the rust and apply a coat of metal primer to reinforce the affected area. For sectioned gutters, owners also have the option to replace the rusted section with a brand-new piece before the rust spreads to the other parts of the gutter.

In some cases, however, a rusty spot is only one hint pointing to a larger issue, as the whole gutter run might be worn down by the effects of wear and tear. If you see other problems affecting the gutter's performance, like sagging or leaks, you may want to discuss the possibility of getting a new gutter with your contractor.
