So, here are the steps on patching holes:
First Step: Clear the Affected Area
Clear off the dirt on the affected area and then scuff it off using a wire brush and remove the sanding. Scuffing the area to be patched helps the sealant have stronger bonding effect. Avoid scuffing area aside from the area to be patched; it may remove protective coatings of the roof.
Second Step: Making the Patch
Make sure to use metal sheet that matches the one that is used in the roof. In making the patch, it should be cut at least two inches past the damaged roof area. Then cut off the sharp corners and cut to fit size. After that, place the patch on the hole and use pencil to mark or outline the area to be patched to check if it overlaps the leading edges of the hole by at least two inches. If not, then make another metal patch or cut off the current patch to fit.
Third Step: Apply the Patch
Spread the sealant on the area outlined by the pencil. Put a generous amount of sealant where the sealant should oozes out when the patch is applied. This is to prevent creating gaps where moistures can penetrate. Apply the patch and press into place.
Fourth Step: Securing the Patch
Secure the patch using pan-head sheet metal screws. The screws should be three to four inches apart from each other, and about one inch from the edge of the patch. Fix the sealants from the edges of the patch to ensure that moisture will be prevented from forming.
Fifth and Last Step: Color the Patch
After drying the sealant, you can apply paint matching the color of your metal roof to hide the repair or the patch. Make sure that the paint you will use can be applied to the sealant.
In doing the repair, make sure to have complete equipment needed. Be careful in walking on the metal roof avoiding making dents on it.
