Scope of Work

Key scopes included:

Complete Roof Replacement

Removal of existing roofing materials down to the structural deck.
Installation of new **multi-ply SBS BUR roofing system** with vapor barrier, tapered insulation assembly, and **reflective cap sheet**.
System components included the **Soprema Roof System**, a membrane designed for high durability and long-term performance.

Insulation and Tapered System

Precision layout and installation of custom **tapered ISO insulation** to ensure positive drainage and eliminate ponding conditions. Roof slope configuration matched field survey data and design intent.
