Poss, stickes, what about winter,
Laying flat, no real issues...depending on your location you will lose some production.
as they are at the moment in a frame on the grass faceing south, in winter they get about 4 maybe 5 hrs of sun , due to buildings and trees, just by going futher down the garden on the shed roof in the morning the sun will hit them now at 6-7am, on the grass its not untill at least 10am before they get full sunlight , so my thinking is the sunlight gained will outway the angle lost
I did a compromise setup as well. I hung mine on the side of my shop. I am old and I just don't want to go up on the roof, and I don't want to ask my kid (27) or anyone else to do something I don't want to do. Asking them to do something I can't do, well that is different.
I think unless your roof has a good pitch already you might find the snow build up be something to worry about. If you go up to the roof to clear snow be careful.

minimal production 6-7am. Do a pvwatts estimate of the angle difference. Any reason you can't pitch the panels on the shed roof?
the roof can just take if ever needed 6 laying flat x3 long x2 wide i would only just get 4 if i was to build a frame so the first 2 did not give a shadow over the 2 at the rear , also the roof is open to the wind that comes up the hill like a funnel between the houses anyone that puts a 6ft fence up during the winter will find there panels 2-3 houses up one morning 
update been running x2 440w and x2 410w for a few weeks just ordered 2 more 410w panels thats all the flat roof covered by the end of the week , its already doing what i needed so next by the end of the year will upgrade the batt pack to 9kw
