"Principal Roofing did a complete tear-off and replacement on our Aurora home. The crew was professional, showed up on time every day, and the cleanup was immaculate. The new Owens Corning shingles look absolutely stunning. Sara was responsive throughout and the price was very fair. Highly recommend!"

"Had Principal Roofing replace our eavestroughs and siding in Newmarket. The work was done in one day, the crew was courteous and professional, and the result looks like a brand new house! Sara was knowledgeable, honest about what we needed, and didn't upsell us. Five stars without hesitation."

"After the ice storm hit Richmond Hill, I had a badly damaged roof and was panicking. Principal Roofing came within hours, secured the roof with a temporary cover, and had the full replacement done within the week. I cannot thank Sara and her team enough. Best contractor I've ever dealt with."
