 Trustindex verifies that the original source of the review is Google. Called them up thinking I needed a new roof and gutters. They stopped by the same day, gave me an assessment of everything and it turns out the roof was repairable. They didn't try to pressure me into any unnecessary work. Just simply he gave me a couple of prices depending on what I decided to do.

They were able to schedule the job quickly for a few days later and by the middle of the afternoon everything was done and it looks great!
