Starting on the Roof

 I've got onto the fun bit and it's going quite smoothly, I've put insulation between the inner and outer skin so that it doesn't get too hot with the summer sun on the black rubber roof.

Pic show nice torx head screw from Toolstation, they come with a drive bit in each box. They don't cam out like pozidrive heads and they drive back out easily too if necessary, pretty quick and effective.
