Hi All
Am sure this topic has been covered before, but I would appreciate some advice/confirmation that I am on the right track. Am building a sloping flat roof garage:
1. 5.4m C16 225x75mm joists, each end to sit on inner half of flat laid block, with 400mm centres, running the width of the garage
2. To acquire 1:60 fall perpendicular to the joist, I am intending to screw fillets (rough sawn/75mm width) on top of each joist in declining heights to allow for fall to rear
3. Also x3 lengths of noggins to support joists
4. Cover joist/fillets with OSB3 - was thinking T&G to allow for fact no level noggins to help support.
Hope this makes sense? Would welcome comments before I make a Charlie of myself! Thanks in advance.
Best Dave
