The contractor of my ribbed metal roof overlaid the metal roof directly on top of my old roof, which was the old asbestos slate tiles. I had heard that it is safe to contain the asbestos rather than removing it. I am so unhappy with the installation. It was full of waves and dimples beneath the screws. The city inspector said that it was not installed according to city code, that it should have had firring strips laid first.
My first question, can the metal roof be taken off and firring strips be put on top of the old tiles and then the roof put back on? I know that the old tiles are broken already, small pieces keep sliding out, and it has been 2 months. What would this look like? Would the broken asbestos tiles continue to slide out be a safety concern, I am presently picking up small pieces still from my yard? Or do the old tiles need to be removed and new metal roofing materials used? Another concern is the use of flashing with caulking versus caulking by itself, around the chimneys and wherever the metal meets the opposing house siding. My contractor felt that metal flashing was basically not needed. I question that position. One last question. The heat causes the metal to expand and contract. The dimples go up and down from the heat.Will this action loosen the screws and pose future leaking problems?
I appreciate your help.
