Repairing A Hole In A Metal Roof
Although metal roofs are tough and durable, there are a number of situations that can cause damage to the roof, such as a falling tree during a storm. If a large amount of damage has been caused, it may be better to replace the section altogether. However, if it is a small hole, it can be worthwhile repairing the damage yourself. This article looks at repairing a small hole in a metal roof:
Get The Right Replacement Metal
It is critical that you get the same type of metal that was used to construct the roof. If you do not know the exact type, take a small piece to the roofing store with you. Either use a leftover piece you have or snip off a little piece of the existing roof at an inconspicuous point. You will also need a caulk gun with sealant, metal snips, a wire brush, and a cordless drill to complete this job.
Clean The Hole Area
Begin by using a metal cleaner (available from hardware stores) to thoroughly clean the area around the hole. Remove any moss or algae. Any dirt or debris not removed will compromise the finished quality of the repair. Once the area is clean, use the wire brush to scuff the metal immediately surrounding the hole; this will rough up the surface of the metal, making it ready to take the sealant.
Measure And Cut The Patch
Measure the size of metal sheet you need, remembering to leave an excess of around an inch and a half around the perimeter of the hole. Cut the patch to size with the snips. It is a good idea to round off the edges of the patch; this prevents the patch from having jagged edges and becoming a snow trap. When applying the sealant, apply it directly to the metal already on the roof, not to the patch. Then, press the patch into place. Once it is in place, you can drill the patch to secure it properly. Use the drill and screws, remembering to wipe away any bleeding sealant when the patch has been drilled into place.
Paint To Finish
Once the sealant has dried, all that is left is for you to do is paint the patch so that it blends in with the rest of the roof. Once this has been done, you will have successfully repaired a hole in your metal roof.
Once you have all the materials, making and fitting a patch for the roof is a fairly easy job and shouldn't take you more than a couple of hours. If you find you need more help, try contacting professional metal roofing contractors for more information.
