Like my 76-year-old body, our 18-year-old house needs some maintenance. When we bought our house 18 years ago, the common roofing material for our flat roof Southwestern style house was tar and gravel. Since then, better roofing systems are now available. So, this week we had a roofing company come and replace our old, tar and gravel roof with some of the new material. It's a big job for the workers because they have to scrape all the gravel off first, then break up and remove the tar coating. Fortunately, the weather was good. It's nice to have my Air 2S drone for the practical use of documenting the work and the results. One improvement is the almost white roof should help during the summer instead of the dark gray of the old roof.
