The exact composition of Enviroshake® is a proprietary trade secret. It is what is commonly known as a composite material that contains plastics, fibers, and tire derived rubber. There are also components that protect it from UV degradation and provide the necessary colouring to replicate the look of cedar shakes.

Enviroshake® is currently offered in only one colour. It starts out as a brownish grey colour and converts or “weathers” to a silver-grey colour that closely resembles a real cedar roof.

Different jurisdictions have different code regulations but generally speaking, Enviroshake® can be installed over one layer of existing asphalt shingles, provided the roof is structurally sound underneath. There is considerable cost savings since there would be no additional cost for removal and disposal of the shingles. There are considerable environmental benefits to this as well because the old shingles need not be put in a landfill. No.

Enviroshake® is recommended for roofs with a pitch of 4/12 or greater. Please consult Technical Support at 1.866.423.3302 or info@enviroshake.com if your roof slope is less than 4/12.
