Inverted Tiled Wedge Insulated Wooden Sloped Roof

Description
Sloped rooves are practical in blizzards as the loose debris simply runs from the roof rather than accumulating. Built of planks coated in resin for insulation, reinforced by wooden slats that have been shaped to fit, this will provide a safe haven from the weather and strong front to any foes who come knocking.
