Roof seamer

The action of the machine bends the two panels together to form a joint that has weather-tight qualities superior to other types of roof systems and cladding.

In 1989, Developmental Industries refocused the niche market by developing a line of roof seamers that were universal to many different panel manufacturers' products and were available to rent by the end-user.

As the rise in popularity in sustainable building products has risen in recent years, the need of a roof seaming tool has also increased.

Most roof seaming machines can have a life expectancy of 20 or more years, if proper maintenance and care are exercised.

All of the following variables should be considered and decided on during the design process of the building: Traditionally, roof seamers are powered by electricity-driven motors.

In all cases, training should be completed before operating alone with a roof seamer to teach proper preventive maintenance steps, simple adjustments and troubleshooting in the event of a machine problem.

In 2015, the Metal Construction Association published a "best practices" guide for proper use and operation of roof seaming tools.

In addition, most manufacturers will recommend scheduled service on an annual basis to ensure internal components are not worn or damaged.

This roof seamer uses 5 sets of rolling forming dies to manipulate the metal roof panel at the "seam" where two panels meet.
The Roof Runner® machine, manufactured in Sweden, was introduced by Butler Manufacturing for the MR-24® roof system.
Progressive roller dies of the roof seamer are used to bend the metal roof panel seam into the desired shape to produce a finished seam profile. This shows a cross-section profile of the seam.

An operator monitors an electric roof seamer as it travels along a metal roof seam.
A hand crimper is used to flat-form the material ahead of a roof seamer or in place of roll forming in some applications.
