True Guard Roofing was fantastic, I had a very old roof with two layers and it was about time to get it replaced, I reached out to them and Art walked me through every step. He is a great employee, I am so thankful for him and their team! They are very good at what they do

I heard of True Guard roofing from my neighbors on the street. They did 4 roofs on our street and so we called and Art and scheduled an inspection. He was very good with roofing and gave my family and I great customer service. We have tile roof so they changed what was under the roof and changed some of the broken tiles we had with matching tiles. We are very happy with the final outcome. I highly suggest working with them.
