Speaking of roof raises...with mine coming up soon I am prepping and studying, studying and prepping...re-reading the Millicent Chronicles, etc. I'm going with the modified farm jacks like Millicent. I considered the scaffolding method but the jackscrews don't go high enough for my ~3' raise, but the modified jacks can and will "hopefully" keep me raised and out of trouble, mostly...
As far as the roof profile goes, I'm thinking I'd like to try something I haven't seen yet and that's a two level roof. If you have seen one please direct me to that brave soul's posting...
What I have in mind is this:
The front half will be raised the full height, ~13'0", to give me room for a sleeping/storage loft up front and more storage towards the rear. The back half will be kept ~12" shorter to allow for future rooftop solar panels, a solar hot water coil, etc.
The first question is how to design the transition from the high side to the low side. I'd prefer a flat vertical drop to allow for the most usable square footage on the rear, lower roof, but I can't quite decide on the best framing method.
At that transition there will be only the one framing member, so do I keep it fully attached to the front, higher roof section or the rear, lower roof section? I'm thinking the front section but then that immediately raises the question of how to frame the now frameless lower section.
- Or - I could do the opposite and leave the frame attached to the lower section and have the same framing challenge with the upper frameless section.
- Or - I could literally split the difference and split the framing member in half and leave the lower roof panel attached to the rear side of the hat channel frame and the upper roof panel attached to the front side of the hat channel frame.
Then I'd have to figure out how to connect the split frame. I think the only way would be to buy one of the hat channel frames (which you can only buy in a full piece) from Freightliner, cut the legs off and then figure out how to modify and weld it into place from the upper section to the lower section.
- Or -
And this is where it gets interesting...I could go with an angled transition, not unlike the front of the bus above the driver's seat, and suck up the lost square footage and have a much simpler installation and fabrication.
