We had a barrel sauna 8' (length) x7' (height) installed this summer and I quickly realized after a few rains that leaking was a problem. Did some research and found a great options for roofing the sauna and went with the following.
Here is what I did...Atlantic Paper Products has a craft paper vapour barrier product with aluminum on one side (facing wood) and craft paper on the other side that is non-porous and weatherproof (purchase from Home Hardware). That goes on the roof first fastened with aluminum tape. Next I strapped with 8' rough cut cedar 1x4x93.5" (inset 1.25 inches on each end) and fastened using 1.5 inch brass screws. I started at the top and measured 24" between to align the strapping with the metal roofing ridges. Again starting from the top I used Ideal Roofing Americana (38x98") metal roofing sheets with one sheet centred on the top and two sheets on each side (5 sheets in total) with 1" overhang at each end. Fasten to the strapping with supplied 2" metal roofing screws. At each end to close the 1.25" inset I then created a jig and made cedar 1"x1.25" rounded trim to fill the inset with the Ideal roofing provided foam closure strips. To allow some air flow drill a few holes in the top trim piece and cover with screen. Use clear silicone caulk between the sauna and trim to fill any gaps. Total cost of material was about $400 (CDN) and about a days labour in total. Sauna no longer leaks and comes to temperature very quickly.
You will see as well that I decided to add an outdoor cold water shower too. Great to cool off!
