There is very little information in english on traditional metal roofing. This is what prompted me to begin studying seaming, and publishing the metal roofing bible in 2018 after years of study and work in this field. I found all of the American resources lacking in this department, and most of the leaders in the field of historical roofing in America lacking in their knowledge of time-honored methods for folding and seaming. This short brochure is one of the few examples that show basic seaming techniques.
Although it does not offer instruction on how to create patterns for unique situations, it gives the reader the basics of the “knots” used to accomplish different details in metal roofing without cutting, soldering, or sealants. These techniques allow the roofing elements to be free-folded, and more importantly it allows the roof to be repairable in the future without disrupting the entire assembly. This is not possible with american flat-lock methods where pans are soldered together creating a monolith.
