Century Roofing did a roof change on my shop, which is a 2400 square foot building. I had found them off the GAF website and I wanted that roof to look like my house's roof. There was a slight discoloring so Century Roofing came to assess what the situation was and took care of it. I would recommend giving Century Roofing a call for roofing. Their price was in the ballpark from what I had from other estimates. I was happy working with Donovan, who was very personable!
