When I was deciding what to use on the roof of the Carabane, I quickly arrived at the conclusion that corrugated aluminum panels would be best. For multiple reasons: -They are light (3kg/m2) -I preferred using large panels over small elements such as tiles, because I would need to anchor each tile individually. I felt that large panels was a more secure option. -They are pretty much foolproof in terms of rainwater shedding, as long as you overlap them properly. -I can use screws to anchor them directly into strapping- no hooks or special anchors needed -I could order them pre-curved with the radius I needed. The manufacturer had certain requirements for the curving radius and the minimum/maximum length of panels. So after a few back-and-forth e-mails with the technician, I came up with my order: The width of the panels was fixed at 1m6, with a corrugation every 7.6cm. I adjusted my design so that the roof would be a whole number of corrugations, so I wouldn't end up wit
