Low Slope Detailing Workshop – Certificate Course


Have you ever wanted to learn more about low slope roofing, or wanted to gain a deeper understanding of the basics of low slope metal roofing?  If you have, then this course is for you. Attendees who join this in-depth workshop will be exposed to some basic level low slope details with the intention to transform perspective on what is actually possible with sheet metal and how it applies to a roof.  As perspectives change, attendees will understand how things shift, and what options (including creative ones) arise when installing metal roofing on low slope style roofs versus steep style roofs. These two types of roofing are extremely different and require very different approaches.

This course will delve heavily into the world of low slope metal roofing while touching on deep slope roofing and discussing their differences in application, from best practices and safety applications to specific tools needed for either style.

Tools and material for this course will be provided by ASM101 and participating partners at the convention.

All students will be required to complete a paper version of the detail we discuss.

A few volunteers will be chosen to complete the detail in sheet metal.

All students will receive a certificate of completion at the end of the course.

This workshop is located in meeting room #S230 workshop requires pre-registration, an additional fee and includes your exhibit hall pass.

Alex Prothmann

Architectural Sheet Metal Trainer, ASM 101

Alex Prothmann has been a fully licensed 308A Sheet Metal Worker in Ontario, Canada for the past 10 years. He got started in metal construction when he went to the classifieds and found an ad for labouring with a sheet metal and siding contractor in Whitby, ON. Little did he know this was the start of a life-long and prosperous career. This company specialized in parapet coping metal fabrication and installation. Coping metal requires a certain level of craftsmanship and attention to detail. From there Alex joined the union, and started working for a copper restoration company where he officially started his apprenticeship. After completing the apprenticeship and all levels of trade school, he became a certified red seal sheet metal worker. There was a local company who specialized in pre-painted standing seam metal roofing that the “coping metal company” boss recommended to him. Alex headed there to interview and they hired him on the spot. Having worked in such a prestigious line of work prior to this position, this particular work felt very different. Like his talents were being wasted. There were also practices he was not quite used to. Because of the nature of painted products, he was forced to use more sealants and face fasteners than ever before. He decided to leave that company and start his own business in 2012. He has been in business for himself for the past 10 years. In starting the business, he became exposed to the unfortunate state of the metal construction industry when it comes to skilled labor availability and learning opportunities. This drove him to start Architectural Sheet Metal 101 (ASM101), a one-stop-shop where skill ranges of all sheet metal workers can not only congregate and share ideas and learn from each other, but also a hub where they can go to learn without outside influences. Where the craft is what comes first before sales and bottom lines.
