Initial Contact & On-Site Evaluation
We begin with a discussion to understand the building’s specific needs, including access constraints, permitted work hours, and the client’s goals (e.g. durability, energy performance, aesthetics).
A qualified technician then visits the site to inspect the roof, take measurements, and assess the condition of the existing structure.
