01 / THE MATERIAL
EnduraShake begins with tropical hardwood—and a home that deserves the real thing.
Each shake is cut from one of our hardwood species from Suriname, South America. Its dense grain, depth, and natural variation give your roof an individual character that a manufactured pattern cannot reproduce.
Our production process is central to EnduraShake’s weather-resistant performance. The result is authentic wood roofing, with independent testing behind its beauty.

NATURAL BY DESIGN
Not molded composite. Not stamped steel. Real tropical hardwood, with the warmth and individuality you chose wood for in the first place.
02 / THE PERFORMANCE
UL 2218 impact testing gives you a concrete standard to discuss with your architect and insurer.
Southwest Research Institute · January 2004Permastrong reports wind performance above 200 mph under ASTM E330 testing when constructed to specification.
Architectural Testing Inc. · January 2004ASTM E108 Class C fire resistance. Review the assembly and your local fire requirements with your architect.
Southwest Research Institute · February 2004*Wind performance depends on the specified construction. Ratings do not make a roof damage-proof or fireproof; Class C is not Class A. Ask for the applicable test reports and installation specifications.
A SMARTER INSURANCE CONVERSATION
A Class IV roof may qualify for insurance savings. Ask your agent to confirm current product eligibility, policy terms, and any discount for your property.
Under certain conditions.
Not a lifetime guarantee.
03 / THE LONG VIEW
A roof is a decision you want to feel good about for a long time. Permastrong reports that EnduraShake has lasted up to 70 years under certain conditions.
Service life varies with location, roof design, installation, and care. Ask for written maintenance guidance and warranty terms for your project.
04 / THE EXPERIENCE
Permastrong reports hundreds of EnduraShake projects. Its work includes historic rehabilitation, with a 2006 Historic Rehabilitation Award from Texas Preservation.
For a historic home, the right material is only part of the decision. We can help your architect review the product documentation alongside local preservation and building requirements.

Names pending confirmation from the owner.
Yes. Every shake is cut from natural tropical hardwood sourced from Suriname, South America. It is not a synthetic composite or a metal imitation.
A Class IV impact rating may qualify for a discount. Eligibility depends on your insurer, location, roof assembly, and policy. Ask your agent to review current product documentation before making a decision.
Both offer natural grain and character. EnduraShake uses dense tropical hardwood and carries a UL 2218 Class IV impact rating. Compare the specific products, installation requirements, care instructions, and test reports with your architect.
Permastrong lists the shakes as 5/16 inch thick × 4 inches wide × 20 inches long, with a weight of approximately 500 pounds per roofing square (100 square feet). Confirm current specifications and structural suitability for your project.
Pricing depends on roof size, complexity, material quantities, and installation. Contact Permastrong with your plans or speak with your architect or builder for a project-specific estimate.
Natural wood may help preserve the original architectural intent. Historic district, HOA, fire-code, and building requirements vary. Have your architect and local authority review the proposed roof assembly before approval.
