Roofing & Building Envelope

Every building needs a solid, professionally designed and installed roof and building envelope to stand up to mother nature’s strength.


Maintaining a roof over its lifecycle is critical to protecting a building’s infrastructure, contents, and occupants, as well as conserving energy consumption. Design Collaborative’s roofing expertise is led by Bob Sanderson, who brings over 30 years of experience designing and troubleshooting roof integrity issues and is backed by IIBEC’s Registered Roof and Registered Exterior Wall Consultant certifications. Whether you’re in need of roof repairs or an entirely new roofing system, our roofing specialists can trouble shoot existing issues or design a new roof for your facility.

Building Envelope

A high-performing building envelope consists of durable, energy-efficient, structurally sound, and aesthetically relevant materials that prevent water intrusion and control air flow. As a building envelope ages and weathers, it may not perform as originally designed, resulting in water infiltration, higher energy consumption, material deterioration and other issues. Through thorough investigation and testing, we identify areas of concern and develop a remediation plan to reclaim your building’s high-performing, younger days.
