"I had a leaky roof. Larry came and quickly was able to determine what was wrong. He clearly has great experience and knowledge of roofing. He was able to come back fairly quickly and complete the repair on a weekend, which was nice because you want any water intrusion to be fixed ASAP. The price was very fair. He guaranteed his work and made sure the professionally fixed all areas where the leak could have been coming from. There was a really bad rain storm a few days ago and the repair was thoroughly tested by it. I highly recommend All Ways Construction for any roofing repair or replacement."

"Tony was amazing. He was the only person able to squeeze us in SAME DAY when we were in a jam. We had an emergency where one of our skylights broke in a storm and every other company wanted us to wait days or even a month. He did everything and cleaned up after. Dont bother calling anywhere else, All phase is the place to go with."
