They’re trying for four days to talk to somebody about my solar panels. Still no word had the same problem when they installed the panels 10 years ago, nobody would return phone calls. I guess the new owner is doing the same thing too. Would not recommend Bison for anything

We had a warranty on the roof installation. However, the roofer DID NOT repair a leak upon contacting the company several times. I do not recommend the company for any work.
