Notching Panels

Hemming Panels

Notching the seams/ribs off is required when preparing standing seam panels for installation. Depending on the seam type and metal thickness, notching can be simple or rather difficult.
After the panels are notched appropriately, the overhanging material is to be hemmed so that it can be secured around the drip edge.

 

Notching

Notching is a repetitive task that is time consuming on a job site. Since seam profiles vary greatly, there is not a “1 size fits all” solution for notching. We recommend a solid pair of cutting snips/shears and a nibbler tool to notch the seams. Watch Mark from Natural Metal Associates notch Rheinzink panels below.

 

Hemming Panels

In general, it is standard practice to hem the last 1″ of the standing seam panel and lock it to the drip edge. Hemming the panel is a way of concealing the exposed (and sharp) end of the roofing panel. Hemming can be done with very simple tools, such as a bar folding tool, or more versatile and precise tools, like roll benders. See below for the variety of hemming solutions that we offer at Stortz Tools.

Once the panel edge is prepped and hemmed, the panel is slid into place.  To achieve a complete and finished look to the panel, the hemmed portion is squeezed, or locked onto the drip edge.  The Eaves Seam Locker is the quick and professional way to finish your panel.

In this video, Craig Hardin of Hardin Exteriors & Roofing is showing his technique for prepping a panel that will than be installed at the eaves edge. Please note that this is an alternative method for finishing the panel.
