Don't do it if you have snow on the roof, as that tends to melt allover your panels.
Do get a little roller, cut one down or even a nice wee brush. This is because there are bits rollers don't reach.
The white will look awfull to begin with, start with the blue. I wished I'd done that.
Set aside as much time as you can manage on the day, It took me a solid 12 hours or so. But i am on the slow side.
Most importantly have fun, I had a smile the whole time i did it. i can't wait to get started again.
If I can help with anything, feel free to drop me a line
Good luck
