Why People are Choosing us for Their roofs

Very friendly and yet knowledgeable and professional. It was a nice experience to deal with a female owner who was on-site and actually supervised the clean-up. I would highly recommend them.”

The project could have been quite a mess, but the crew maintained my property even while taking cedar shake off my roof. The end result is beautiful. Many of my neighbours have commented on the look of my roof. I have referred Weldun Roofing to several and know that they too were pleased with the experience.

We came home on Sunday and our ceiling in the kitchen had caved in. It was a horrible mess caused by a leaking roof. We called the insurance company, and 4 days later, we still didn’t have a repair or a solution. I called Weldun and spoke with Patricia. She put my mind at ease and I had an estimate and an install date in hand by the end of the day. Her crew came out and worked on a Saturday to ensure we didn’t incur any further damage. Weldun is coming back in the spring to put a new roof on our garage.
