"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!"

Roofing questions, answered by experts

In some cases, yes, you can put a second roof layer over architectural shingles, but it depends on your home’s structural stability and the local building codes where you live. Architectural shingles are thicker and heavier than standard asphalt shingles, so you may need structural reinforcement or a structural engineer’s inspection before proceeding. Additionally, some building departments don’t allow for two roof layers, regardless of the roof type. You should ask a professional if ripping the old roof off before installing the new one is the best option for you.

Yes, many contractors offer warranties for their work. Confirm terms before hiring.

Yes, roofers can repair and replace roof trusses. In fact, because trusses are such an important part of your roof’s structure, it’s best to have a roofing contractor deal with a damaged truss. If you try to fix the problem without the right skills or knowledge, your roof could sustain further damage or even collapse.

If you live on the West Coast or anywhere with the threat of wildfires, you likely want to take steps to fireproof your home. Besides waterproofing and life span, rubber roofing also is noted for being fire resistant. Consult a professional roofer for details on what type of roofing would be best for you if fire resistance is a priority.

Yes, moss can be dangerous for your roof if left in place to grow without treatment. The moss soaks up and holds moisture. Having a constantly damp roof could lead to problems with rot for the parts of the roof that consist of wood. Additionally, a patch of thick moss may draw insects and birds, which could damage the roof. Thick moss could block the roof’s drainage system. Water then may back up after a rainstorm and cause further damage that could eventually lead to roof repair expenses or the cost of roof replacement.
