They just completed the job last week so this is not a long term review. I was impressed with the quality of work during the installation process. Between the two brothers they seem to have a good process for checking and verifying each other's work so that any mistakes were caught right away. They were recommended to me by a friend and in turn I would not hesitate to recommend them as well. They replaced a low pitch tar and gravel roof for us and significantly increased the R value in the process. They seem to know the low pitch/cathedral ceiling roofing systems well. I think communication could be improved a bit on timing and progress etc, but it was no worse than other contractors that have done work for me.
