Metal roofs are known for their longevity and durability, and in many areas, they can last up to 50 years. We love metal roofs because they can withstand heavy rain, strong winds, and even extreme weather such as hurricanes.
However, damage can occur, as can wear and tear. In many cases, a damaged metal roof doesn’t need to be replaced but may benefit from repairs. Fixing a roof can extend its lifespan and save you money.
In this post, we’ll talk about how to repair a metal roof and consider situations where a repair makes more sense than a roof replacement.

Are Metal Roofs Hard to Repair?
The difficulty of a metal roof repair depends on how extensive the damage is. Another factor to consider is how comfortable you are working at the height of your roof.
If you have a small puncture or a damaged panel, you might be able to repair it yourself. However, if you have widespread rust or a major structural issue, such as damage that occurs after a hurricane or tornado, we recommend consulting with a professional roofer.
You should also consider your roof’s warranty before undertaking any DIY repairs. If the damage is covered, contact the company. If it is not covered, we recommend checking the terms of your warranty to determine if repairs made by a non-professional contractor could void it.
Handy homeowners who aren’t afraid of heights and who have the right tools and equipment will find it easier to repair a metal roof than someone who doesn’t own tools and is uncomfortable on a ladder.
How to Repair a Metal Roof: 6 Steps
The difficulty of repairing a metal roof depends on the type of repair needed. For instance, if you have a standing seam metal roof, you may be able to simply fill a small puncture with roofing sealant. If there’s a tear or hole, though, your best bet will be to use a metal patch to seal it up.
Here are some easy-to-follow steps to try if you would like to repair a standing seam metal roof on your own:
- Clean and scuff the area around the repair. Use a household cleaner and paper towels or a cloth to remove any dirt, mildew, or algae. Then, use a wire brush to scuff the metal that will be patched to help the sealant stick. Be careful not to scuff more of the roof than needed, as this can wear away some of the protective coating.
- Cut a piece of sheet metal to fit the hole you’re covering. You’ll want at least two inches past the edge of the damaged area on all sides. Then, round off any sharp corners on the patch since they can warp upwards. You can use a file to make sure all the edges are smooth.
- Use a pencil to trace around the patch on the roof. Make sure it’s centered and that there are two inches of overlap. Cover the area within the outline with metal roof sealant.
- Press the metal patch on top of the sealant. The sealant should come out a bit on all of the edges to ensure there are no gaps underneath the patch.
- Use sheet metal screws to screw down the patch. Space them every few inches and close to the edge of the patch. Choose short screws that will only set into the roofing panel. You don’t want the screws going all the way through the panel, as it can damage the roof decking or rafters.
- Smooth out the edges. Use a putty knife to smooth down the sealant that oozed out from the edges of the patch. Don’t scrape it off, just smooth it over so it protects the edge.
If you want, you can paint the patch to match the roof after the sealant is done curing.
Should You Replace or Repair Your Roof?
There are many factors to consider when deciding whether to repair or replace your metal roof after damage.
First, if the damage only impacted one small area, you can probably get away with repairing that section. You might need to replace one panel, but if the rest of the roof is in good condition, there’s no need to replace the entire roof.
On the other hand, if the roof has pockets of damage throughout, you may want to consider replacing it.
Secondly, consider the age of the roof. If you plan to replace it in the next couple of years anyway, it might not be worth the time or expense of trying to repair it. A metal roof lasts up to 50 years, so if you’ve only had it for a couple decades, a repair may be the way to go.
Finally, consider your budget. A metal roof replacement is much more expensive than a repair or two. However, if you find yourself in the position of having to take on several repairs, it might be best to replace the roof. A professional roofer can help you weigh out your options by sharing specific costs and other considerations.
Frequently Asked Questions
Can you repair a leaking metal roof?
Yes, you can repair a leaking metal roof, and it’s essential to address leaks promptly to prevent water damage to the interior of your home and degradation of the roof structure. Repairs may involve patching holes or tears with metal roofing tape, sealant, or patches specifically designed for metal roofs.
While some repairs can be DIY projects for those with experience, professional assessment and repair are recommended to ensure the integrity of the roof.
Are metal roofs harder to repair?
Metal roofs are generally not harder to repair than other roofing materials, but the approach to repair can differ. The difficulty of repair can depend on the type of metal roof (standing seam, corrugated, etc.), the extent of the damage, and the accessibility of the roof.
Metal roofs also require specific materials, such as metal-specific sealants and coatings, to ensure a lasting repair. Successful repair requires knowledge of the material and its installation methods, so it’s crucial to follow manufacturer guidelines or consult a professional.
How long will a metal roof patch last?
The sealant used to patch a metal roof can last up to 10 or 20 years, depending on the elements and how well the repair was done. If you’ve patched your roof, it’s important to check it periodically, particularly after a heavy rain or wind storm, to ensure it’s holding up.
How can I make my metal roof look new?
If your metal roof is just looking dull and isn’t damaged, you can try cleaning it with mild dish soap, water, and a sponge or microfiber cloth. This might remove enough grime to make it shiny once again.
Will fixing a roof on my own void its warranty?
It can, and the original roofer will be able to tell you whether applying a patch to a metal roof will void its warranty. In some cases, you’ll need to hire the original company to handle the repair, since they won’t be able to warranty the work done by someone else, whether that’s you or another roofing company. If your roof is still under warranty, get in touch with the contractor to address all repairs.
The good news is that a metal roof from Erie Home is not only professionally installed, but also comes with a 50-year, limited lifetime transferable warranty, so you can rest assured your home will be protected for decades to come.
Repairing a Metal Roof: Final Thoughts
It’s possible to repair a metal roof yourself, provided you have the tools and necessary materials and are comfortable working safely from a ladder. Patching a small hole or tear isn’t difficult, as long as you follow the proper steps.
However, in many cases, it might be worthwhile to hire a professional to handle the repair, or to discuss replacing the roof entirely.
