Missing evidence lowers the score because we can't check it. It doesn't mean it doesn't exist. Claiming a profile never changes the score. Evidence context, not a guarantee of workmanship.

I highly recommend Gamma Roofing! They responded very quickly after I found a fallen gutter issue at my house. They are honest, responsible and reliable professionals. The repair was done fast and for a very reasonable price. They also took the time to check my roof at my request, which really gave me peace of mind. I really appreciate their help and will definitely be recommending them to others.
Fast, honest, and friendly. Thank you!
Gamma Roofing did a great job. They completed my 1900 s.f asphalt roof in a day and cleaned up very thoroughly afterwards. They also cleaned my gutters and installed a mesh over it to prevent tree leaves from clogging it up. Their service is very good and their pricing is very competitive. We highly recommend Gamma Roofing if you need a reliable contractor.
Reasonable price, quick service. Nice guys

Worth checking yourself
Their public evidence comes from a single source. Look them up on another site before deciding.
No credentials are shown here and the business has not claimed this profile. Ask to see certificates and insurance directly.
Never agree to roof work from a cold-caller at your door or an unsolicited 'we noticed your roof' note. That is the classic roofing scam.
Get a written quote that itemizes access (scaffolding or a tower), the exact materials, and the workmanship guarantee, not a vague day rate.
Be wary of demands for a large cash deposit; agree staged payments against work you can actually see completed.
