What do recent reviews say?

Most customers praise Alpha Roofing for fast, professional metal roof installations completed in a single day, with particular mention of staff like Alan, Echo, Jocelyn, and Sandy who communicate clearly and follow up during the job. A small number report serious post-installation leaks and describe unresponsiveness when seeking repairs, creating a stark contrast to the overwhelming positive experiences.

The business operates across the GTA with a large crew that works efficiently and cleans up thoroughly. They handle metal, shingle, and flat roofs, plus skylights. Pricing typically comes in competitive to lower than other quotes, which has prompted some customer surprise at quality given the value.

Skylights Unlimited

Markham-based installer known for skylight replacement and sun tunnel work, with owner Denis directly involved in consultations and problem-solving. Crews show up on time, complete jobs within promised timeframes, clean thoroughly, and explain the work step by step. Reviewers consistently praise quality finishes, from Velux grid replacements to high-end condo projects, and note reasonable pricing for the calibre of work. One older review questions a shift in their online messaging about curb construction methods, but this surfaces no complaints about actual job performance.
