Dynamic Alliance installed a new roof on our Auto Repair shop building. The building has had multiple additions and has been modified many times for previous businesses. The roof Thad & his crew installed has eliminated many leaks where the additions have been added & the insulation below the roofing membrane has made for a much more comfortable work environment in the winter months. Thad and his crew were very efficient. They did not disrupt business while they were working & left the site clean when finished. Thanks for a great job.
