I have a home that was built between 1912-1917. It has the old wood shake on it and they are falling apart. I have a man who says I can put a metal tile roof on the home and it looks like it might be really beautiful. The name of the the roof is Stile. It can be found at www.mtlsales.com. Do you know if I would hurt the integrity of the home by putting this roof on? Do you know if this is a good product? Thanks for your time. Dave MacDevitt
