Reliable EPDM Supplier for Cold-Climate Roofing

Raheen is a roofing contractor comes from Ontario, a region known for its long and extremely cold winters, was searching for a cost-effective supplier to alternate Firestone’s black EPDM roofing membrane.  which can withstand severe temperature fluctuations without cracking—performance that is crucial in northern Canada. Because of EPDM’s excellent elasticity and long-term waterproofing stability, he wanted to ensure the material from new supplier would perform consistently in such harsh conditions.

After evaluating multiple suppliers, he contacted Qingdao Shuangshi New Material to explore a more competitive product option. We sent him samples of our homogenous EPDM membrane, and all physical and chemical performance indicators successfully passed their lab testing.

Once the tests were completed, he began asking about the price per square sqft. We provided a reasonable and competitive quotation. Surprisingly, he did not try to negotiate further. However, he expressed a deeper concern: the long-term quality stability of the EPDM membrane. He explained that in their community , the reputation matters more than saving a few cents; any product failure could hurt his business and his long-established local trust.

To address this concern, Shuangshi New Material offered a 3% quality guarantee deposit, refundable after five years provided no product-related quality issues arise during that period. This arrangement gave him peace of mind. He assured us he had no intention of withholding the deposit unnecessarily; he simply wanted confidence in the long-term reliability of the membrane.

Reassured by our commitment, he proceeded to place an order for 60-mil standard black homogeneous EPDM roofing membranes in two sizes: 10' × 100' and 17' × 100'. After the membranes were delivered to the job site, his installation team reported smooth handling, easy deployment, and excellent performance during installation.

Satisfied with both the product and the service, Raheen expressed strong interest in establishing a long-term partnership with us.
