Awful company to deal with from the start. The owner Jason Chi came to my house for a free roofing replacement quote. I was paying for my roof myself, but Jason insisted that I try and scam my insurance company. He didn’t even get on my roof and asked who my insurance company was repeatedly.
After asking him to leave several times, he became angry and stormed out of my home. His office called the next day and asked who my insurance company was. I told them to never call me again and hung up on them. Pure scam artists!!
