Sloping roofs have single slopes that don't meet at the top. Roof slope is measured in inches per foot rise over 12-inch depth. A-frame houses have two steep slopes, mansard roofs have four
Geodesic domes offer cost-effective large structures with quick construction. Most common dome design starts from icosahedron, which forms hexagons. Building process can be completed in days instead of weeks
Steeply pitched rooflines and decorative half-timbering are characteristic features. Exteriors are asymmetrical with dynamic rooflines and mixed-material facades. Multiple chimneys, off-center front doors, and wide stone stairways are typical
SketchUp offers various roof types including gable, hip, gambrel, mansard, and Dutch gables. Basic roof creation starts with box drawing and eave lines. Roof slope is defined using x/y axis ratio (e.g. 4/12 pitched roof). Central lines create roof path, followed by gable ends
Mansard roof features two slopes on each side, with steeper lower slope. First known example by Pierre Lescot on Louvre built around 1550. Popularized by François Mansart in early 17th century. Became fashionable during Second French Empire (1852-1870)
Roof is the top covering of a building protecting against weather elements. Roofs can provide additional living space and serve multiple functions. Roofs protect against rain, snow, sunlight, temperature extremes and wind
