Anyone know how much raw lumber, paper, battens, counter battens + ridge tile build on top of this? Height from outside ground to roof ridge is now on the drawing 2931.7mm. I thus have 68mm left to build on. Doesn't seem like it will be enough, but how extremely precise does the roof height need to be? It's not an exact science to determine the average ground level. And who will actually come to measure it?
Would you be willing to measure once how much it built up in your case above the rafters on the ridge beam? It would be greatly appreciated.
I didn't have anything better to do, so I edited a construction example from Träguiden and changed the roof slope to 17 degrees. When I measure in the dwg file, the tongue and groove is 23mm, counter/battens 25+25mm, the tiles are surely some standard thing they've drawn in. From the top of the roof beams to the top of the ridge tile it's 217 mm!
