The ridge tiles are 2mm brass angle, not yet finally fixed in position. Joints were represented by soldering on short lengths of 1mm wide brass strip, a total of about 55. Getting all those equally spaced and at 90 degrees to the edge of the angle was quite testing to say the least.
The ones at the back were soldered to a strip of brass for fixing to the rear of the building and most of the back of the angle removed.
I think the brass strip should have been a 4mm scale coach floor ! They're fixed in place with Peco track pins, which I use quite a lot - but hardly ever for fixing down track. Before fixing the exposed faces were primed with light grey primer.
The roof after 10 or 11 (I lost count !) sprayed coats of paint. The colour is now reasonably even but some of the slates are still soaking up the paint, producing a rather rough surface.
Shown in close up here. In retrospect I should probably have primed and fully painted the slates before fixing, and rejected any with a poor surface finish (not that I'm likely to use these again).
The finished or "That'll have to do" stage, or I might just run a knife along the horizontal joints to open them up a bit. Some of the slates have been touched up with slightly different colours or shades of the base colour, so subtle it hardly shows ! The colour of the slates is probably too light, but the building is in a corner of the layout that's not too well illuminated, and what looked reasonable on the workbench looked too dark when it was in situ. The ridge tiles at the back were also a problem, whether to include them or not, as in theory the roof should slope away beyond the backscene at a shallower angle. For that reason, after trying red/brown and dark grey, I painted them just a slightly darker grey than the roof slates so they don't stand out too much against the light blue backscene. The right hand end of the gutter is drooping a bit and needs adjustment.
