Flashing Roll Forming Machines

Flashing roll forming machines are an essential equipment for manufacturers of metal building components like roofing, siding, panels, studs and more. This guide provides a comprehensive overview of different types of flashing roll forming machines, their key features, applications, specifications, suppliers, installation, operation, maintenance and more.

Overview of Flashing Roll Forming Machines

Flashing roll forming machines are used to form trim or flashing components from coil stock of various metals like steel, aluminum, copper etc. Flashing provides weather sealing, prevents moisture ingress and thermally insulates metal roofing and wall systems.

Roll formed flashing components include drip edges, rake trims, corner trims, head trims, jamb trims, sill trims and more. Flashing roll formers process flat strip stock into angled, v-shaped or box shaped profiles continuously.

Key benefits of using flashing roll formers:

  • High production speeds up to 120 ft/min
  • Capability to form complex and heavy gauge flashing up to 0.125 in thick
  • Superior quality and consistency versus other methods
  • Reduced material waste
  • Lower labor requirements
  • Ability to integrate with other downstream equipment

Types of Flashing Roll Forming Machines

There are two main types of flashing roll formers:

Standalone Roll FormersIn-line Roll Formers
Configured as complete roll forming lines withdecoilers, pre-cutting, notching, punching, rolling stations, post-cutting and exit tablesDesigned to integrate into existing manufacturing lines by removing decoiling and exit end functions
Require dedicated operator and floor spaceCompact and flexible for tight spaces
Higher capacities and productionLower capacities but seamless integration
Well-suited for high volume dedicated flashing productionBetter for mixed products or lower volume flashing

Key Components of Flashing Roll Formers

Flashing roll forming machines have the following key components in sequence:

  • Decoiler: Feeds raw coil stock into the roll former
  • Feeder: Controls stock flow into the forming stations
  • Pre-cutting: Cuts sheet length prior to forming
  • Punching & Notching: Punches holes or notches if needed
  • Forming stations: Progressively forms the flashing profile
  • Post-cutting: Cuts formed profile to length
  • Exit table: Stacks or transfers finished product

Modern roll formers may also include pinch rolls for pulling stock through each station, servomotor-based controls, and integration of punching, notching, or embossing units between stations.

Flashing Profiles and Geometries

Common flashing profiles and geometries formed by flashing roll formers:

  • 90° angles: For drip edges, corner flashings
  • V-shaped: For rake trims, ridge caps, roof transitions
  • Box-shaped: For parapet flashings, head flashings
  • Complex angles & bends: For door/window jambs, sills, curved components
  • Embossed patterns: For decorative finishes

Advanced 3D modeling and tooling design allows flashing roll formers to produce almost any geometry.

Flashing roll forming machines provide an efficient solution for high volume production of roofing, siding and wall flashing components. With speeds up to 120 ft/min, gauge capacities up to 0.125 in thick, and ability to form complex profiles, modern roll formers offer significant advantages over alternate methods. By understanding key specifications, configurations, pricing ranges and applications, metal component manufacturers can determine if investing in a flashing roll forming system will increase productivity, lower labor, and reduce per piece cost. Supplementing production with lower volume brake pressing provides flexibility to meet both high and low quantity requirements. With robust preventive maintenance and experienced operators, flashing roll formers can reliably produce components to meet roofing industry demand.


Q: What metals can be formed on a flashing roll former?

A: Most common metals are aluminum, galvanized steel, zinc steel, copper, and stainless steel. With proper tooling design, any ductile metal alloy coils can be formed.

Q: Can a flashing roll former make gutters and downspouts?

A: Yes, with the addition of specialized tooling and accessories for forming longitudinal profiles. Common gutter profiles like half-round, K-style, box gutters etc. can be produced at high speeds.

Q: What thickness of metal can a flashing roll former handle?

A: Standard flashing gauges from 26 gauge (0.025″) to around 18 gauge (0.050″) are commonly run. Heavy gauge capacity up to 0.125″ is also possible on some high-end models.

Q: How long does it take to changeover dies on a flashing roll former?

A: On machines with quick change tooling, profile changeover takes 15 minutes to one hour. Older models take 2-4 hours for changeovers.

Q: What factors determine the price of flashing roll forming machines?

A: Key factors are line speed, width capacity, number of forming stations, automation features, brand reputation, and overall robustness of construction. Prices range from $50,000 to $500,000.

Q: How much space do these machines require?

A: A typical standalone flashing roll former needs approximately 15-30 feet length by 10 feet width of floor space. In-line versions require less space.

Q: Is it better to buy new or used flashing roll forming equipment?

A: For maximum longevity, productivity and support, new machines are recommended. For smaller budgets, used and rebuilt machines provide good value at 40-60% lower cost.
