Metal roofing, being a very durable and long lasting type of roofing, has become popular among homeowners and is becoming a common roof replacement to other less durable and lasting types of roofing. While having a long lifespan and strong durability to the elements, metal roofing still has to be taken care of and maintained to preserve the quality of the roofing and ever further its already long lifespan. Over time, minor damages may occur due to some circumstances which will require it to be repaired and how this repair is carried out can either make or break the integrity of the roof.
If during regular roof inspection you happen to find a hole in your metal roof, you have to work on it as soon as possible to prevent further damage and to prevent leaks which can further damage the interior structure of your home. A simple hole repair on a metal roof may seem a challenge but with the right procedure, it will be over in a breeze.
To prepare, you will need some sheet metal, metal snips, and sheet metal screws(pan-head), a cordless drill, a caulk gun, and wire brush, some paint and a paintbrush and a pencil, a cleaner(non-residue), and some sealant(urethane).
- Clean out the damaged area – Make sure that the area you are going to be repairing is clean. If the damage was caused by rust, make sure to remove the rust around the area. If the damage was caused by debris, make sure to clear it out. This can be done by using your wire brush.
- Take measurements and cut – In roof repair, you have to make sure that you are using a patch with the right dimensions. Measure the damage on the roof and add two inches to each side giving you the measurements for the patch that you should cut. Shape the patch properly so as to prevent snow from entering once installed.
- Install the patch – Apply sealant around the damaged area carefully staying within a pre-marked shape of the patch. Once the sealant has been applied, press the patch onto the area. You know you are doing it right when sealant squeezes from all around underneath the patch. If there are areas where there are gaps, make sure to fill them out to prevent any moisture from getting through the repair.
- Securing the patch – Once the patch has been correctly pressed into the area, it will have to be secured even further with the use of some screws. Using your drill, drill holes on the patch with an inch distance from the edge and with three to four-inch distance from each other. After drilling, screws in the screws securing the patch.
- Finishing touches – When doing roof repairs, you will want to finish things up to make it look like there wasn’t any damage in the first place. The goal is to make it look as if no repair was carried out. Do this by painting over the area to make the patch look uniform with the surrounding roofing.
