Kevin finished the diamond turtle! FB folders rejoice.

Great project from New Jersey metal master and tradroofing.com student: https://www.facebook.com/kevin.rosselli.39

Kevin, musing on the inevitability of the next roofing crew causing damage to this, which can and should last the lifetime of the building. It brought to mind, one of my early works that was later destroyed by an eager insurance claims industry. Ready to sell work that was un-needed because of “dents”

This roof, completed by my company: Patina Slate & Copper, was destroyed by overzealous “hail damage” sales tactics, and ignorance. Only a few years after installation: in spite of being perfectly sound. The contractor who ended up doing the work sought me out to get up training on standing seam, however it was much after this roof. Truly a crime.

tradlive is back! feb23

hey folks. I’m firing this thing up again, in an attempt to get back to automated live streams / posting… lord help me. just field testing right now so don’t expect too much. @ me for #quickmaths #roofmaths #lifeadvice #insults

who’s still watching in 2019

hip patterns series 4:12 and 6:12

Over my time in the shelter from November, thru the beginning of February, I worked on these hip patters. These are useful for creating folded hips on a standing seam copper roof, although any light gauge material that will not rust can be used. Eventually I will get them all scanned and available on an index page. One-off patterns are always available. Contact for metal roofing design and pattern work!

Learn to fold metal roofs!

In 2015 I left Rhode Island, and Casa Buena Builders to bring seamed roofing to the english-speaking world. I had been studying at night, bringing my skills up with folding and joinery; while working full-time in historic preservation, remodeling, and slate roofing. My favorite project of the tour that year was this seminar I was invited to give at the HPTC (Historic Preservation Training Center) headquarters in Frederick, MD.

Almost all of these techniques were completely foreign to the seasoned pros from the National Parks Service. I hope to one-day have all of these rules codified in English, and accepted at least internally within organizations like NPS. We may never be able to regulate the entire market like the better countries but within institutions and even preservation districts it is possible. I know all properties benefit from having roofs that are designed to last as long as the building.

This handout (PDF link) below demonstrates how to layout and cut the valley seam, from the ground as long as you know the two pitches of the intersection roof faces. This is very important with metal roof seaming. Much like in timber framing: the piece must be fully fabricated to exact specifications before they are assembled. In the same way: we do most of our design and layout on the drawing board, and on the cutting bench. There is very little “in place” fabrication, only folding assemblies.
