What Best Materials does

Best Materials is a U.S.-based e-commerce distributor of roofing, waterproofing, and exterior building materials headquartered in Phoenix, Arizona. The company sells a broad catalog of more than 25 product categories directly to end customers via its bestmaterials.com storefront, including EPDM and TPO/PVC single-ply roofing membranes, caulks and sealants, waterproofing systems, deck and roof coatings, fasteners, pipe flashings, metal goods, hot-air welders, safety equipment, and concrete repair products sourced from multiple manufacturers. Its customer base spans professional roofing contractors, DIY homeowners, RV owners, and DOT/civil works buyers, and the company explicitly advertises worldwide shipping.

The business operates primarily as a transactional, one-time-purchase distributor with no disclosed subscription or recurring-revenue mechanics. Pricing is product-specific with quote-based bulk ordering rather than standardized published tiers, and the company supplements its catalog with a substantial content library (FAQ database and how-to videos) to drive organic traffic and educate buyers on product selection and installation. Originally founded in 1994 as Copperstate Waterproofing & Roofing Supply, the company was renamed and merged under Best Materials LLC in 2003, and was acquired by Construction Supply Group (CSG) in 2020 while continuing to operate autonomously under its own brand and trademark. The firm has 11-50 employees and is privately held, with no public revenue disclosure available.
