I live in a Cul de Sac of 6 homes. After seeing the new roof that Excel put on my home, 3 neighbors hired Excel for their new roof - that's how great Excel is ! After 22 years, due to hail, Excel put a second roof on my home. Excel was efficient and took good care of my property. BTW, my neighbors used Excel a second time, too .
