The Roof
The most difficult decision to make was to choose the type of roof this structure should have. My intention was to have buildings that are well-maintained. I decided to match the lumber storage shed's roof to the platform covers of the main building by using corrugated metal roofing.

Several of the Builders in Scale 7-1/2' panels are already installed in this photo. I cut them to length using the NWSL "The Chopper II". It cuts cleanly if you really snap the handle down quickly and firmly. The panels were glued to the roof structure using 5-minute epoxy.

I needed to complete the support structure for the shorter half of the roof, which I did before I took this photo. The final count is 686 pieces of wood and 5 sheets of the corrugated metal.

After the corrugated metal sheets were installed, I used a method I saw on Allen Keller's video (#39) visiting George Selios' layout for the third time. First, I sprayed the roof with Dullcoat. Next, using his standard India Ink and alcohol mixture, combined with some Raw Sienna acrylic paint, I "painted" the entire roof. The Dullcoat gives the paint something to stick to. The lesson learned is to only put one layer on and let it completely dry. If not, the alcohol takes all the material off again. I completed the roof with several colors of weathering powders.
