What mansard roof means
A mansard roof slopes on every side, each side with a steep lower slope and a nearly flat upper slope. The steep part often reads as a wall and holds windows for a top floor living space.
Where it matters on a roofing job
Two roof types on one building: the steep sides take shingles or slate, the flat top takes a low slope membrane. Price them as separate areas with separate materials, and plan staging, because the steep faces cannot be walked.
