There's not more room in the comment on your answer, so I shall reply to your last point here. Looking at the photos again, you could be right. The photos seem to show two or three different buildings and each does show a shallow course of tiles, while only one shows a dormer. The bottom course of tiles is very much shallower than the others. In EN-GB, we'd use the adjective "shallow", not "short" for that (though deeper than 1 inch). We also wouldn't use the word "fascia" for a section of roof pitch, though we might use "fascia" for the side of a dormer.
This apparent EN-GB : EN-US difference adds to the complexity involved in the usage of such adjectives in English. E.g. the depth of a drawer is the distance from front to back, while the depth of a box is the distance from top to bottom. |
