"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

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.

Yes, installing a new metal or tin roof can increase your home's value. A metal roof's longevity and durability are major selling points for prospective buyers, as it means they likely won't have to worry about a roof replacement. These roofs can last 40 to 80 years, which is significantly longer than traditional asphalt roofs.

In terms of return on investment (ROI), homeowners may see an increase in home value of around $7,000 to $8,000, which can represent 60% to 70% of the installation cost. Another way to measure ROI is per square foot, which can range from $3.00 to $8.40, with higher returns in areas where a durable roof is particularly beneficial.

Yes, shingles should overhang the drip edge, typically between 1/2-inch and 3/4-inch. An overhang shorter than 1/2-inch can allow wind-driven rain to get under the shingles and damage the roof deck or fascia. Conversely, an overhang longer than 3/4-inch increases the risk of shingles getting caught by strong winds, which can lead to roof uplift. Always check your local building code for exact overhang requirements in your area.

There are two main types of roofing shingles: 3-tab and architectural. Architectural shingles cost more than 3-tab but offer a more unique look and can last longer. However, 3-tab shingles are lightweight and affordable, and many people use them for both patching roofs and installing new roofs. Ultimately, the best type for you depends on your budget and your home’s aesthetic.

Most roof leaks occur where shingles meet or where there are sealants or seams in the materials. This is common around skylights and at any point there is a break in the roof such as corners and edges. Roofing materials are incredibly strong and resistant when overlapping, but any change in that can cause gaps where water can enter.
