This was on the local news. It will cost Sullivan county $200,000 to remove the metal roof, replace the plywood underneath, and replace the insulation on jail. If the video works, it will also show rust under the metal. The metal they are removing looks good, so it may last 50 years. Guess the contractor who installed the metal roof didn't know what they were doing, right?
I've seen some contractors put metal over existing shingles, some even put 1/4 inch fan-fold over the shingles first. I will predict that there will be more of this happening in the future because metal roof are becoming popular. I'm sure some will say they have had metal roof and no problems. Metal really isn't the problem, the problem is humidity.
Indiana has a humidity problem that some of you don't. This morning schools are on a 2 hour delay. When the dew point and air temp are the same, you have fog. You will also have condensation, yep even under the metal.
