Rust, also known as corrosion, can be a big problem for your house, especially for the roof and gutters. This is even more of an issue when these parts of your house are made from metal. A specific type of rust, called galvanic corrosion, happens when two different types of metal touch each other. This can make one of the metals rust faster than it usually would, which can weaken your roof or gutters over time.
To avoid this kind of rusting, it’s best to use the same types of metals together. For instance, if you’re using a zinc-coated steel mesh for your gutter, you should also use zinc-coated steel screws for your steel roof. This helps because the metals used in your roofing system will then have similar properties, which reduces the chance of corrosion.
Another thing that can cause rust is when metal surfaces are often wet. This can happen when your roof or gutters are exposed to dew, fog, or rain regularly, especially if the water is slightly acidic. This can be a bigger problem if your gutters are blocked with leaves and debris because the water won’t flow away and will sit there, which is perfect for rusting.
A good way to solve this problem is by installing a mesh over your gutter. If you choose the right size mesh, it can stop leaves and debris from getting in and blocking up your gutters. This reduces the chance of water sitting in your gutter and causing corrosion. It also makes sure water can flow away properly, which can stop water damage to your home.
When choosing a material for your gutter mesh, there are some options like galvanized steel, COLORBOND® steel, zinc-coated steel, and stainless steel that are designed to resist rust. But remember, the key to avoiding corrosion is to make sure the materials are compatible. So, it’s important to choose a material that works well with what your roof and gutters are already made from.
For instance, stainless steel doesn’t rust easily. However, if it touches another material like COLORBOND® steel, it can cause your roof to start rusting sooner than expected. That’s why it’s so important to make sure that your roof, gutters, and gutter mesh are all made from materials that work well together.
In the end, understanding how rust happens and taking steps to prevent it can really help to make your roof and gutters last longer. By picking compatible materials, installing them correctly, and doing regular maintenance, you can protect your home and keep it safe and dry for many years. So, when you’re choosing a gutter mesh or planning a roof installation, remember to think about the metals involved and how well they work together to avoid problems with corrosion.
It may seem like a lot to consider, but taking the time to choose the right materials and install them properly can save you a lot of hassle and money in the long run. After all, the goal is to keep your home safe, dry, and looking great for as long as possible. And with a little forethought and careful planning, you can do just that. So next time you’re up on your roof, remember these tips and know that you’re doing your part to protect your home.
