What Marathon Roofing Products does

Marathon Roofing Products, Inc. is a privately held, family-owned US manufacturer of commercial roofing drainage and ventilation systems, founded in 1966 in Buffalo, NY and currently headquartered in a 40,000 square foot facility in Orchard Park, NY. The company's core product lines span roof drains (Aluminator retrofit series with proprietary ProSeal/ProMaxx mechanical seals, Copper-Tite, Poseidon stainless steel, MaraPak/MaraDrain PVC, and Cast Pak cast iron), roof vents (Insulvent, Prevent, Ex-flow, M-105, Sol-A-Vent), roofing equipment and accessories, and — via its MRP Supports subsidiary founded in 2013 — pedestal/paver support products for raised flooring and rooftop plaza applications.

The business is differentiated by proprietary mechanical seal technology (the 8-inch ProMaxx Aluminator is described as the only 8-inch retrofit drain with mechanical seal in the industry) and by certifications to ASME A112.6.4, CSA B79, and ANSI/SPRI RD-1 standards, with company President Tod Cislo actively participating in ANSI/SPRI standards-setting for retrofit drains. The product line is broad but organized as a unified specialty manufacturer rather than a platform-plus-modules business, with offerings in aluminum, copper, stainless steel, PVC, cast iron, and lead.

Marathon operates a hybrid go-to-market combining a national independent manufacturers' representative network (covering all 50 US states plus Mexico) with distribution partnerships through major building materials wholesalers including ABC Supply (multi-year Preferred Vendor), Beacon Building Products, Ferguson, DAS Products, and Best Materials, supplemented by direct sales via website/phone. End customers span commercial roofing contractors, architects and specifiers, building material distributors, and building owners/property managers. Pricing is unit-based with free freight on orders $3,500+ to commercial warehouses and same-day shipping for orders before noon Eastern. Leadership transitioned in February 2025 with Jake Cislo and Amanda Fachko appointed as Managing Partners, continuing Cislo-family ownership.
