am re building the pop top roof of my 30 yr old van thought of using steel but decided will stay with wood framing , cause of weight etc ,
questions i have are
1 the original roof frame was just mainly 19 x 45 pine either in joined pieces to make larger / smaller pieces or as is , was told should be using treated pine , but local ( small town ) lumber dealer does not stock , was thinking of just using normal pine giving it a few coasts of undercoat and top coat to seal it would this work just as well ( none of the old roof frame was sealed at all , and lasted 30 yrs )
2 want to use expanding foam filler to fill all the gaps in the roof ie has new 20 mm metal u shaped frame which will have the timber in it pressing against one side and want to use the foam as a filler in the 5 mm gap left will this cause a problem ? it wont cause the light metal channel to bend as it expands ? will have plenty of space to expand up . could apply in small doses and build it up but will different layers of it bind together ?
3 using panel rib for the roof has only a 4 mm ridge
view 1 has the panel over the edge angle which means there will be a gap all round the roof which will have to be filled , water flow is right direction straight off roof ( has a small fall from centre out to edges )
view 2 was going to put it under the right angle edge panels of the roof for a neat appearance but of course the water run off is then wrong and may pool over joint
think view 1 is better option but any suggestions ?
