"We have been having a problem with pigeons hanging around all day on/under our solar panels. I originally had a handyman who was going to install mesh around the edges of the panels and yesterday (the day he was supposed to come) found out he didn't have insurance/license so I canceled. I then went into a Zoom meeting and heard the darn pigeons cooing and fluttering all over the roof and got so upset. I came to Angi and found Best Choice Roofing (aka Best Way) - he called me back right away and in less than an hour he was here. The first thing he did was hand me his business card with his License # on it. Very professional. He got up on the roof, then in a few minutes came down and gave me an estimate. Once I accepted, he called his team to assist and he started on the roof. They were super clean - blew out my gutters, blew everything out from under the solar panels, and made sure to blow the porch and front of my house to remove any debris. I had peace of mind that they were licensed and insured. Today I am happy to announce, I have not heard ONE PIGEON! I know this company usually does more like roofing and gutter-type projects, but I will be letting any of my neighbors with solar panels/pigeons know who to call. Great crew. Thanks so much!"
