What do recent reviews say?

Sing Yang and his crew earn consistent five-star ratings for honest consultations that sometimes recommend repair over replacement, skilled roofing work completed fast, and exceptional after-sales care. Reviewers praise the 10-year labor warranty, prompt callbacks years after the original job, and meticulous cleanup. One complaint involves a driver's inattention on the road.

The business handles roof replacement, repairs, eavestroughs, siding, skylights, and emergency calls across central and eastern Ontario. Clients report competitive pricing, transparency in estimates, and a founder known for troubleshooting complex leaks and traveling to jobs in unfamiliar towns.

Based on limited recent reviews, so treat this as low-confidence.
