Interesting operation, Janse. I can't quite relate to turf on the roof.

I'm impressed. What's under the turf? (Can you describe the roof construction and waterproofing?)

Thank you for commenting PJ1. Turf on the roofs is a very old Norwegian tradition, have may be been used from 500 B.C. The most important thing about a such roof is the waterproof layer under the turf consisting of several layers of birch bark. The lifetime of that kind of roof was about 60-80 years. Nowadays we use a special kind of plastic instead of birch bark. The mission of the turf was to keep the bark in place and also functioned as inulation. Of course the construction must withstand the weight from the turf (up to 300 kg pr. square meter together with pressure from the snow layer in the winter. :-)

Thank you. Starting with the roof beams (rafters?), above this a wind barrier made of a special canvas which is waterproof but allows water vapor diffusion. Then comes a wooden roof, often wood fibre boards. Above this a bituben - based type of underlay. After this the special plastic. Well known products here in Norway are: Platon Xtra Torvtak and Icopal Fonda Torvtaksplate. I was using the last one. Skråtak: Platon Xtra Torvtak

Now I use sprinkler irrigation but later I will install drip irrigation I think. ( Normally we get so much rain that irrigation isn't necessary) :-)

Once a year the grass ought to be cut, not too short (10cm). I think I will use a chythe. :-)

I think sod roofs were common when Scandanavians settled Minnesota, and less common, but known here in Eastern and Northeastern Iowa, where birch trees can be found. Here is sketch showing an example on a one room school house in Iowa, circa 1900, from Iowa Public Television. Sod Roofed One Room Log School House | IPTV


Thank you for explaining how this works. I never understood it. And yet, I would still like to know, do you spray for weeds? Do you remove trees from the roof? It seems like there would be more maintenance than the typical asphalt shingling we have here in the U.S.A.

Hey Janse, how do they hoist a lawnmower up there? It would take real courage to tackle that roof with a riding lawn mower!!

Your shot reminds me of a song from the past.

Thank you so much for commenting mroeder75. More than 800 000 Norwegian emigrated to mainly Wisconsin, Minnesota, Iowa and North-Dakota and I'm sure many had buildining with sod roofs. A lot of Norwegian cabins also have asphalt shingling on the roof. I agree a turf roof needs much more maintenance. (If you like to keep it nice). I think I will remove trees and high weeds mechanically instead of using herbicides. :-)

A riding lawnmower is not a option for me Jer, I have to find another way. Thanks a lot for the song. :-)

My roof angle is 30 degrees so I suppose you could handle that? :-)
