Enviroshake®’s exact formula is a trade secret. Our products are composite materials created
from 95% recycled materials, including post-industrial plastics, natural fibres, and elastomers.
Our formulation is enhanced with a proprietary blend of additives that protect our products
from UV degradation and allow them to truly replicate the look of natural cedar and slate.
Post-industrial materials are highly robust and do not have the impurities that post-consumer
blends struggle with.
Enviroshake has been in business since 1998, making us not only a leader, but a pioneer in
the composite roofing industry.
