Metal Roof Repair: Mistakes to Avoid Metal Roof Repair: Mistakes to Avoid
Metal roofs are wonderful, but metal roof repair is something that many people dread. Although it’s not a complex procedure, it’s one that many people end up getting wrong. It’s important to know what not to do, as well as the steps you should take, and there are a number of mistakes you should avoid.
Don’t just try to use any metal you have around for the patch in your metal roof repair. It’s important that the metal of the patch is the same as that of the roof, in order for it to adhere properly and so it won’t wear prematurely. If you’re not sure what metal was used on the roof, ask others until you receive a definitive answer.
When you have your metal patch with the corners mitered and folded over, don’t forget to sand it. It’s a step that can easily be forgotten, but the sanding, to the point that the sanded metal is shinier than the rest of the metal, is vital. It helps the flux stick to the patch, and you need it as you’ll be soldering the patch in place as one stage in the metal roof repair.
Once you have the patch soldered in place, don’t imagine you’ve completed the repair. A patch like this might hold, but to be properly effective it’s going to need added protection. It’s simply part of the job and you need to be sure to do the rest of it. When soldering, don’t simply solder in spots around the metal. You need a continuous seam, with no gaps all around the metal patch. If you leave any gaps, at all it becomes ineffective.
Remember that you’ll need 2 more patches as part of the metal roof repair, and that they need to be bigger on all sides than the original patch. Bigger means 2 inches larger on all sides, so they will give a real overlap on the original patch. That will allow for a full, watertight seal. Cutting them too close to the size of the original patch won’t give you that luxury. Make sure that you cut 2 of these patches for extra security.
People often forget to weigh down the patches when they’re working on them. Using a cinder block as a weight keeps the patches firmly in place, so your hands are free to work, and also forces them down in contact with the metal roof, which improves the bond between patch and roof. Always use a weight when working with metal roof repair; it makes your life much easier.
Don’t skimp on the roofing cement when applying the top 2 patches. Make sure they stick down thoroughly, and that there’s not a corner of flap that’s loose. After you’ve applied the final patch, don’t think that’s the end of the job. To be absolutely certain everything is covered, you need to add a complete seal to the metal roof repair.
