  • "They do not reply to calls or emails when you have a problem. My insurance company needed an itemized bill for us to get the rest of the insurance money. Have been calling and emailing them for 3 months and still no response."

  • "Bought a house these guys roofed. After numerous attempts to explain they needed to fix a leak on the roof they did they finally came out and caulked a hole and called it good. After wanting a more permanent fix they cut away a lot of the siding along the roof line for no reason. Now the leak is fixed and I have a bunch of my siding cut out. The flashing did not need to be replaced. Don't use this company they are shady and a headache now I have to somehow redo my siding with estimates of 7k or more!!"
