Good evening, I am after a little advice . I am in the process of building a 12 x 8 garden shed/small workshop, walls, clading etc now done and am now working on roof. Due to a, working single handed and b, tight space to move martial in I decide to use 6 x 1 softwood treated boards laid lengthways for the roof with heavy duty felt over the top. Now dispite having the boards for a few weeks after fixing them down I have suffered some shrinking between boards, what I am wondering is should I fill the gaps before felting or leave them as they are allowing for any movement between boards. The felt will be nailed down only.
thanks for reading above waffle and for any advice you may have.
