Andrew Yang

Hi, I’m Andrew.

I work primarily on residential and commercial roofing projects across the Greater Toronto Area.

My focus is on long-term roof performance—how local climate conditions, material behavior, and construction details affect durability over time. Many roofing issues develop gradually rather than from a single event, and accurate diagnosis requires understanding how roofing systems age in real-world conditions.

I share technical observations and practical insights based on field experience and ongoing project work. You can visit my company website below to learn more.
