Owner
The service provided by Marvin & Alex was professional, courteous, & respectful. My flat roof replacement was entirely completed within less than 4 hours due to the large number of men doing the job. (7 men !!!) They took pictures of the roof after completion so that I could see what they had done. I am very pleased with the job. My thanks to Andrea in their office for her courtesy and for always being so pleasant to speak with. JohnT.
