I have dealt with construction people for 50 years and very rarely have I run across a young man so competent and intelligent in his work as Gonzalo. He did the whole job in 2 days. ( with 15 mph wind first day). That may not sound like much but this is a roof of 60 squares. 88 feet by 35 feet each side. I was worried to say the least as I have heard from Mueller metal horror stories of people losing these sheets in wind. I didn’t need to worry I had 3 sheets left. The job is beautiful. I will try to upload a pic. I would recommend him to my best friend. ( I actually did).
