Learn How to Repair Holes in Your Metal Roof in Five Steps

With the proper installation, the life span of Metal Roofing faces no competition. However, even though metal roofs are durable and last long, they still need to undergo proper maintenance and repair to ensure their quality and integrity all throughout. A repair done on a metal roof can really improve things and even last longer than the roof itself or it may just be a cause of more complications on the roofing system resulting in more costs and more labor required.

If you have a hole in your metal roof that has resulted in a leak, you will need to deal with it immediately to prevent the development of mold. Conducting metal roofing repairs can be difficult but if you understand everything, there isn’t much to worry. Today, we will go over repairing a hole in your metal roof in just five steps. First, you will need:

  • Sheet metal, metal snips, and pan-head sheet metal screws
  • Cordless drill, caulk gun, and wire brush
  • Paintbrush, pencil, and paint
  • Non-residue cleaner and urethane sealant

Now, let’s go through the five steps in patching up the hole in your Metal Roofing:

  • Clear the area of repair – Take note that holes in metal can develop due to a variety of reasons including rust, deteriorating, and falling debris. If it is any of these, it is sure that the area of the damage will be dirty. Make sure you properly clean out the area and then scuff around the hole with your wire brush
  • Take measurements and cut out the patch – Take measurements of the damage and use it as a basis for the patch that you will cut out from the sheet metal. Taken note the patch should overlap two inches from the edge of the hole. After cutting out the piece, make sure you properly round it to prevent snow and ice from being trapped. Mark the patch outline with a pencil.
  • Install the metal patch – Around the hole, apply some sealant and make sure that you do not go over the pencil mark that you made. After applying sealant, press the patch onto the area. You should be able to see sealant squeeze out from the sides. If there are any areas where sealant does not squeeze out, apply some there to eliminate all the gaps.
  • Secure the metal patch into place – Once you have properly pressed the patch into place you will want to secure it into place with some screws. Drill holes into the patch making sure that they are within three to four inches within in each other in the perimeter and within one inch from the edge of the patch. After drilling, screw in the screws securing the patch.
  • Do some finishing touches – Once the patch has been secured onto the Metal Roofing, you can paint the roof to make sure that everything looks uniform and the patch will not look out of place. Paint also helps to really seal the top layer and prevent water from penetrating.
