Repair a Hole in a Metal Roof System

Roof repairs can be a hit or miss depending on how you do it. Poor repair work can lead to recurring of the same problem and extended damage to other parts of your building. This might lead to the replacement of the entire roof. So how do we repair holes in a metal roof system? We describe our processes below:

Assemble the Tools

You need several tools to repair a hole in a metal roof. You can get some of these from local hardware, a home center, or a roofing store. Some of these include:

  • Metal snips
  • Cordless drill
  • Caulk gun
  • Pencil
  • A cleaner
  • Pan-head metal screws
  • Putty knife
  • Wire brush
  • Paintbrush
  • Paint
  • Urethane Sealant

Clean the Place you Want to Repair

Regardless of what caused a hole in your metal roof, to successfully repair it, you have to clean the repair area. Use a cleaner to get rid of the dust, rust, algae growth, and any other form of dirt. Don’t leave behind any cleaning agent residue because it can compromise the integrity of your repairs.

Scuff the Repair Surface

The next step is to use a wire brush and scuff the metal panel at the damaged part. Doing this makes it easier for the sealant to bond and effectively cover the hole. Avoid scuffing a bigger area on your metal roof than necessary because doing this removes the protective coating, which exposes your roof to corrosion.

Cut a Sizable Patch

Once you have readied the hole area, measure and cut a metal patch that can overlap it. Make the patch two inches wider all around the scuffed surface. You want your patch to be round and not sharp on the edges to avoid it being a trap for dirt, snow, and ice. Then place your patch on the area and mark around it using a pencil. This helps you examine if your patch covers the spot as it should.

Install the Patch

Take a urethane sealant and apply it to the repair area. This should cover the area you marked with a pencil. Ensure you apply liberal amounts in the damaged area without leaving any part in the marked space. Then place your patch precisely on the area. Press the patch so that the urethane sealant oozes from all ends. If you left any voids or gaps during the sealant application, not all ends will ooze the sealant. And this later allows moisture to penetrate and damage the patch.

Screw the Patch in Place

Once your patch is in place, secure it using metal screws. Separate the screws three to four inches apart. You also want to screw them at the same depth for equal pressure. Don’t screw through the metal roof to avoid accessing the rafters or decking. Wipe away the oozing sealant after the securing process. Then allow your patch to set in the position according to the instructions from the sealant manufacturer.

Match the Patch With the Roof Using Paint

Your patch should look similar to your metal panel for aesthetic purposes. That’s why you should paint it. Take your wire brush and lightly scuff the patch and the surrounding area. Paint the scuffed area using similar paint as the rest of the affected panel. Make sure the paint works well with the sealant to be sure of good results.

Special Considerations for Metal Roof Hole Repairs

Metal roofs are some of the hardest roof systems to repair out there. The biggest challenge is differences in expansion rates of the repair materials and that of the metal roof. Even a slight variation in expansion and contraction rates eventually leads to cracks and splits, which make patching it pointless, if not a bad idea. That’s why it’s recommended that you hire a roof repair expert to do the patching for you.

Another reason you should hire an expert to do your metal hole repairs is for your own safety. You want someone that can assess the condition of the entire roof because a hole in a metal roof could mean that there are decking or structural issues.

Don’t attempt to fix holes in your roof if unsure of what you are doing. If you are uncomfortable with heights, it is also a bad idea to go up there to do anything. Your best bet is to get a roofing contractor who comes with a complete repair kit to provide quality results safely.
