Building envelope consulting has been the foundation of Raymond since our founding in 1992. What began as a roof consultancy has grown into a comprehensive building envelope practice supporting owners, architects, and contractors across the full lifecycle of a facility.

Our team evaluates, designs, and manages roofing, waterproofing, and exterior wall systems that protect buildings from moisture intrusion, air leakage, and thermal inefficiencies. By combining building science, engineering expertise, and hands-on field experience, we help clients understand how their building envelope performs and how to improve it.

From forensic investigations and condition assessments to new system design and construction oversight, Raymond delivers practical solutions that extend service life, reduce operational risk, and improve building performance.

With professional engineers, registered architects, and multiple IIBEC-certified specialists on staff, we provide the technical depth needed to solve complex building envelope challenges.
