We recently decided to upgrade our shingles to architectural rather than asphalt,so got 4 estimates. We liked Mike right away and decided to give the job to cosy.It is a very difficult roof but Mike assured us there would be nothing to worry about.The materials all got delivered on wed. afternoon and the roofers got to work on it bright and early thursday morning.They worked hard for three full days, all the while being pleasant and professional. They put in extra time on saturday to finish because rain was forecast on sunday.My wife and i really appreciated there cleanliness as well as there work ethic. The job was done on time and on budget.We love our new roof and the only reason i'm giving them 10 stars is because there isn't an 11th.Thanks Mike!!
