hi all. long story as to why, but ive just almost finished installing a new pitched roof onto an older 'curved top' van. it had nothing to do with leaks, but as part of siting it next to our van (for our daughter) we agreed to put a new roof on to keep it in keeping with other vans.
I will try to upload some images of how we did it - that's not to say there may be better ways, but this way worked for us.
I used pre treated slate laths and used my table saw to put a groove (using a double blade) along their length (2m long)
I then cut 6mm ply into 2.4m lengths which were 75mm at one end and 175mm at the other - I then used one to make a template of the curve of the roof
insert the 6mm ply into two pieces of grooved slate laths and using glue and 8mm dowels (pins or screws made the laths split, dowels worked perfectly) into holes drilled through both materials - lots of dowels along the curved edge
- that gave me strong preformed and very much uniform roof trusses.
I then screwed slate laths along the length of the van, I used three each side - you could use more. they were screwed into the vans structure along the wall and wherever you could feel there was the original roof structure - its not that hard to locate them! I used stainless steel screws.
I then fixed the preformed trusses onto them and then added laths again on top of the trusses this time four per side - on which I fixed the roofing tile sheets.
the photos will make it a little clearer and show you what I did
