Over my years in the metal roofing industry homeowners will frequently contact me after they’ve had their metal roof installed and say “Wow I love it it looks great! What do I need to do in order to maintain it?” Well, I’m glad to say that in most cases there is very little you need to do, especially if you’ve made a good choice up front and gone with a roof system that has a PDVF or what’s called a Kynar 500® and Hylar 5000® PVDF resin-based finish on it. Those paint systems are really known for the fact that they hold Integrity for the long-term, they don’t tend to gather a lot of dirt that you have to worry about, they also tend to resist chalking, so there’s not a lot you need to worry about with those paint systems.
So if you have a metal roof, what do you need to do you? My main advice is once a year maybe every six months, just take a slow walk around your house, look up at the roof, make sure that there hasn’t been some sort of damage perhaps from a tree limb, or or something else that might have caused some damage to the to the roof…make sure that you don’t see any panels that have slipped out of place, any flashings that perhaps might have moved a tiny bit. Take a look as best you can (don’t get up on the roof) but from the ground, perhaps even using a pair of binoculars, take a look at any sealants on the roof…perhaps any penetration such as pipes or side walls… take a look at the sealants, make sure that you don’t see where they have cracked or broken loose or anything. If you pick up on any of those things, go back and contact your contractor and let him know what you see, and I’m sure they’ll be glad to come out and take a look at it, and make any adjustments or changes that are necessary.
As far as ongoing maintenance with your metal roof, I’m pleased to tell you there really isn’t any. Just check it out every once in awhile, take a look at it see if anything’s changed. If it has, alert your contractor, they’ll take it from there.
