They have lollypop stick style roof tiles so I will be buying some similar for the rest of the roof. Speaking of the rest of the roof: My new dormer windows are much smaller than the old ones so I will also have to replace the roof with a new piece of ply-wood and get some holes cut in it the right size for the new dormer windows!
This is what they looked like after being painted and bricked.
A close up on the pointed roof bricking: This space was way too small to fit the stencil into to stick and plaster over with the compound so I had to just plaster some compound into the space and, with a cocktail stick, scraped out the spaces in-between for the base colour to show through. The resulting 'bricks' are possibly slightly bigger than the stencil bricks, but with the compound sticking to the stencil, all the bricks seem to be difference sizes anyway, haha!
I'm looking forward to my new roof now!
