About TerraShield

Bringing a proven membrane to U.S. roofs.

TerraShield Inc. is the U.S. Master Agency for Envirotuff™ ACC Weathering Membrane, manufactured by San Miguel Yamamura Woven Products.

TerraShield Inc.

Solve the roof once. Not repeatedly.

Too many metal roofs get patched year after year until the only option left is a full replacement. We think there’s a better path.

TerraShield introduces ACC to the U.S. market and supports everyone who works with it: we train and support installers, appoint distributors, help specifiers with technical data, and work with building owners to find the right solution for their roof.

We’re also leading U.S. product testing and certification for ACC, starting with independent solar reflectance testing and a Cool Roof Rating Council rating.
