Keeping sheet metal siding in good shape is a smart way to protect your home’s appearance and value. Over time, minor wear like dents, scratches, and small rust spots can start to show up, especially in well-used areas. The good news is that it doesn’t usually take a village to patch up sheet metal siding on your house.
You can handle most small repairs yourself in a few fairly simple steps and get a solid result—this guide will send you off with everything you need to know first. From assessing the damage to finishing touches, this is how your siding can stay in shape for longer.
Assess the Damage First
Metal siding is primarily popular for its durability—in fact, it was used in 2.5% more construction projects for exterior walls in 2021 than ever before. While it’s tough and versatile, examining your sheet metal siding is the first step to making sure any repairs go smoothly.
Check for dents, scratches, rust spots, or small holes that might need attention. Take a good look along edges, corners, and lower sections where wear often shows up first.
Signs to watch for:
- Tiny dents from rocks or debris
- Rust patches, especially near fasteners or seams
- Scratches that expose bare metal
- Small holes or punctures from impacts
Spotting these early helps you decide what you can handle on your own and what might need a professional’s eye.
Preparing the Metal Siding Sheet to Patch
Before diving into repairs, it’s essential to prep the area.
Start by cleaning the siding to remove any dust, dirt, or grime that might interfere with your patch. Mild soap and water or a soft cloth work well for this step, and be sure to rinse and dry the area fully.
If there’s rust, use a wire brush to carefully remove any flaking or peeling parts until you’re down to solid metal.
Basic supplies you’ll need:
- Metal filler (for patching holes or dents)
- Sandpaper (to smooth out repairs)
- Gloves (to protect your hands)
- Soft cloth (for cleaning and drying)
Repairing Small Holes and Scratches
Filling small holes or scratches in sheet metal siding is easier than it seems. For minor dents or holes, metal filler does the trick.
Steps for patching small spots:
- Apply a small amount of metal filler over the hole or scratch using a putty knife.
- Smooth out the filler evenly so it’s flush with the siding.
- Let the filler dry completely, following any drying times on the product label.
- Once dry, sand the patched area lightly until it blends in with the rest of the siding.
This technique works well for minor damage, helping keep water and rust from causing more trouble down the line.
Tackling Bigger Dents and Rusty Spots
Larger dents or rusty areas may need a bit more attention, but they’re still manageable with the right approach. Here, a metal patch can cover the area securely.
Steps for bigger repairs:
- Clean and sand the dent or rust spot to remove any rough edges.
- Apply a metal patch (found at hardware stores) with adhesive or screws, ensuring it sits flat.
- Sand around the edges to create a smooth transition with the original siding.
For more rust-prone areas, consider using a rust converter before patching, which helps neutralize any remaining rust and prevents it from spreading.
Finishing Touches and Weatherproofing
After repairs, a few finishing touches will seal the job. To ensure your patches are well protected, consider adding a coat of primer to any bare metal or patched areas.
Then, apply paint that matches your siding for a seamless look. This not only keeps your siding looking fresh but also adds an extra layer of protection against moisture and weather.
Once the paint is dry, seal edges with a weatherproofing product if needed to keep water out and extend the life of your repairs.
Routine Maintenance Tips for Sheet Metal Siding
Regular upkeep helps prevent damage in the first place. Simple maintenance tasks can go a long way in preserving the look and durability of your siding.
Helpful maintenance:
- Rinse siding occasionally with a garden hose to remove dirt and grime.
- Inspect for signs of rust or dents at least twice a year.
- Apply touch-up paint to any areas where scratches or scrapes reveal bare metal.
These steps keep your siding in top condition and allow you to spot small issues before they become big problems.
Knowing When to Call in a Professional
Some siding issues are manageable as a solo project, but some situations call for expert help. For example, if you notice extensive rust that has spread across several panels, dents that seem to impact the structural integrity of the siding, or damage that keeps coming back after repairs, consider a professional inspection.
Experts have the tools and experience to assess any underlying problems, like hidden moisture damage or weakened fasteners, that could affect the overall stability of your siding.
