What Our Customers Say
Ontario Roofing did an incredible job on our roof replacement. They were professional, efficient, and the attention to detail was impressive. The crew was friendly and made sure everything was done to our satisfaction.
They were very communicative and kept us informed throughout the entire process. The quality of their work is evident in our beautiful new roof.
They were transparent about the costs and the timeline, and there were no surprises. The workmanship is top-notch, and our new roof looks amazing.
The roofers worked in the 100 plus heat and rain to finish before the hard rain came.
Recently I had both my garage and my home roofs completely torn off and replaced with a completely new environmentally favorable product.
They worked in my attic on a day when the temperature was near 100 degrees. They were pleasant, polite and considerate. Excellent communication and follow up.
Homes and buildings
From Ranch Homes to Commercial Roofs
