Why is Enviroshake the most desirable synthetic roofing material on the market?

As a leader in the synthetic roofing industry, Enviroshake takes pride in offering premium aesthetics, industry leading unsurpassed durability, and lifetime performance. While backed by a 50 year, fully transferable, lifetime warranty, Enviroshake has been tested for all markets to meet or exceed the highest ratings in the roofing industry. Rest assured for many years to come with a roof that will protect and enhance the curb appeal of your home.

Our dies are made from the 3D images of natural slate and shake to ensure true to life texture, thickness and aesthetics that will have you guessing is it natural or is it Enviroshake? We offer the tradition, beauty, and luxury you want, with the performance you need.

What are Enviroshake products made of?

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.
