MODI Systems was founded in 1982 with a single goal: build a better torch for professional roofers. The result was the Magnum Torch, the first on the market with a wind-resistant electronic starter, a lightweight balanced brass shaft, and a 33-foot rubber hose — still a feature no competitor offers. MODI has since expanded into Modi Trowels, hot air welders, and a line of roof drains, vents, scuppers, and pipe collars for both commercial and residential roofing.
Built Around a Better Torch
MODI Systems set out in 1982 to solve a specific problem: torches available to roofers at the time were heavy, poorly balanced, and hard to start in wind. The Magnum Torch answered that with a wind-resistant electronic starter and a lightweight, properly balanced brass shaft designed to reduce installer fatigue — and it remains the only torch on the market offering a 33-foot rubber hose.
That single product built MODI's reputation across the U.S. and Canada, and the company has since grown its torch and trowel line alongside a separate catalog of roof drains, vents, and accessories.

Where It Fits on the Job
MODI is a go-to for any torch-applied modified bitumen job, where the Magnum Torch's balance and hose length reduce installer fatigue on larger commercial roofs. The separate drain and accessory line covers the drainage details that come up on nearly every low-slope commercial project, independent of which membrane is specified.
