Cleasby Manufacturing

What Cleasby Manufacturing does

Cleasby Manufacturing Inc. is a privately held, San Francisco-based manufacturer and distributor of equipment and tools for the commercial and residential roofing industry, in continuous operation since 1949. Its core product line centers on asphalt melting and delivery kettles spanning 30 to 1,200 gallon capacities (pumping, non-pumping, and hot-rubber/air-jacketed variants), supported by proprietary technologies including the Emissions Eliminator afterburner system (490 CFM, connects to kettles to enable open-kettle operation on sensitive projects), double barrel spiral flame burners producing industry-leading 2 million BTU/hour, an air-jacketed insulated kettle design claimed to melt asphalt ~30% faster, a 60 g.p.m. high-capacity pump, and the exclusive Hot Pot mini kettle for 5–9 gallon rubberized-asphalt buckets. Around this core, the company distributes complementary roofing equipment from technology partners — Leister single-ply welders, Graco spray equipment, Winco industrial generators, RGC hoisting equipment, and Honda/Briggs & Stratton engines — and offers hand tools, brackets, modified torches, safety equipment, rooftop accessories and hatches, and custom-fabricated truck beds.

The business is sales-led and direct, with quote-based unit pricing, toll-free phone ordering, and a downloadable PDF catalog (2018 version referenced). Customers reach Cleasby through four company-owned locations: the San Francisco headquarters at 1414 Bancroft Avenue, service centers in Westminster, CO and Clearfield, UT (offering quick-turnaround equipment repair), and a sales office in Riverside, CA, plus a Denver regional contact point. The customer base spans commercial roofing contractors (single ply, cold process, built-up roofing), residential roofing contractors (patch jobs, shower pans, smaller additions), road maintenance companies, and construction fleet operators, with no named anchor accounts disclosed and no subscription or recurring-revenue model. The company operates as an independent, privately held California corporation with no disclosed parent, subsidiaries, outside investors, funding rounds, or M&A history.

Revenue and headcount are not publicly disclosed; the firmographic headcount range of 1–10 employees is inconsistent with a multi-location manufacturing and service operation that has been running for 75+ years and likely understates the true workforce. No AI, software, or digital-channel capabilities are present in the product set, and there is no evidence of recent funding, acquisitions, leadership changes, geographic expansion, or product-line pivots in the available data.
