Aluminum and steel gutters usually have high rust resistance, but they can still corrode due to age and extreme weather. When this happens, should you repair or replace them completely?
What Causes Rusty Gutters?
Tree pollen can have high acid levels that eat away at the acrylic and zinc coating of gutters. Without these layers, the material will get exposed to moisture and suffer from accelerated corrosion.
- Dust, Debris and Leaves
These often clog gutter systems that lack regular cleaning. Standing water can cause sagging and damage the material’s protective coating. Regular gutter maintenance removes dust and debris and prevents gutter clogging.
- Reaction With Other Metals
Galvanic corrosion happens when two metals touch each other through water or other conductors. For example, your copper gutter must only work with copper roofing, screws and fasteners so that it won’t corrode.
- Changes in Temperature
Sudden temperature fluctuations will cause gutters to break down rapidly. Local weather in coastal areas or mountain regions can cause rapid temperature fluctuations.
Can You Still Repair Rusted Gutters?
In some cases, rusted gutters can still be fixed. But for severe rusting, it’s best to replace the entire system. Here are some solutions that you can choose from:
Gutter experts can still sand away the rust if it is still at an early stage. Sandpapers of varying grits work well in removing rusted layers.
- Removal of Rusted Sections
Your gutter contractor can remove the rusted gutter sections and replace them with new ones. The downside of this method is that it creates more seams, making your gutters prone to leaks.
- Gutter Replacement
Gutter replacement is recommended for rusted gutters that are already beyond repair. If your gutters have too many holes due to corrosion, it’s best to replace them completely.
