I was wondering how far the curve would go, if the sides would bulge so to speak…..The flat or sloping pent style roof was my original thought, but SWMBO has always hankered after a Shepherd's Hut, and so she therefore desired
theher carport to have similar roofing. I may well end up doing as you suggest. We'll see. Especially as I can't get any bloody steel deliveries or posthole digger hire at the moment. So I'll have to wait for a couple of days* weeks* months* years*. *Insert suitable duration here, according to HMGs wishes.
(That's my excuse, and don't you lot do anything to tell her otherwise. I'm quite enjoying my peaceful and restful lock-down)
Ref felt roofing, cheaper to use yet scottish weather has a habit of ripping it off. At least with tin it is only as secure as the nails securing it.
Ref holes in the metal degrading, using rubber grommets while nailing helps immensely. Using a metal spike for accurate nail positions does ensure secure nails. Metal paint in that nice shade of british racing green adds a bit of colour to it…...
almost forgot, L shape horizontal metal panels along the edge help against the wind as do twisted L bracket tie downs...
Having to secure the same roof two winters in a row teaches you to respect winter storms of 80-90mph winds.
