Нижние концы стропильных ног опираются на мауэрлат (4). Пересечение скатов образует наклонные (12) и горизонтальные ребра. Горизонтальные ребра называют коньком (5). Пересечение скатов, образующие входящие углы, создают ендовы и разжелобки (6). Края кровли над стенами здания называют карнизными свесами (7) (располагаются горизонтально, выступают за контур наружных стен) или фронтонными свесами (11) (располагаются наклонно).
