Roofs Modeling Assign

Directions: Using cardstock, you will create models of different designs.

1. You must model: a. b. Shed Roof c. Roof d. 2. Choose 2 other roof styles from the list to model. 3. All structures will have a 2” x 2” base unless you choose to model the Cross Gabled Roof or the Cross Hipped Roof. 4. Add tabs for gluing. 5. All Models will be evenly spaced on an 11x17 piece of cardstock.

The primary function of any roof is protection from the elements. The type of roof is determined by the climatic conditions and architectural style. In some regions roofs must be designed to shed and bear weight of snow and ice. These types of roofs have more pitch or curvature. Whatever the area, it is essential to plan the roof carefully to enhance the design of the structure.

Roof overhangs are designed to add to the appearance of a building and to protect the upper walls from moisture. Overhang on ranch style buildings may provide shelter and shade for outdoor walks.

A flat roof is used on more contemporary homes. It requires the least cost for materials and labor, but a flat roof requires special care in sealing against leaks.

The shed roof is the simplest form of roof construction. It has one slope, usually to the rear of the building and the greater overhang in the front. A shed roof is is inexpensive to construct. A variety of the shed roof is the monitor. It is a combination of two shed roofs, with between the two roof levels.

The butterfly roof is two shed roofs which slope to the center of the building with the low point in the center. It must be built carefully to prevent water leakage.

The is probably the most common type of room because it serves several practical purposes and is easily constructed. The gable roof has two surfaces sloping away from the ridge. The slop varies from nearly flat to a steep pitch.

The cross gabled roof is like the gable roof, but has two parts that cross.

The hip roof has four surfaces slanting from a peak or ridge. The visual effect of this style of roof is a shortening of the length of the building.

The cross hipped roof is similar to a hipped roof, but this roof has two parts that cross .

The roof has two surfaces, each of which slopes on two spearate planes. The upper slope form an approximately 30° angle and the lower is approximately 60°. This type of roof is common in Dutch Colonial houses and in barn construction. It provides greater head room in the or uppermost story.

The is another form of double sloped construction. The upper section has only a slight slope, about 15° (close to flat). This type of roof makes it possible to have rooms. It is found on French Provincial houses.

The salt box roof got its name because the sharply sloping gable roof resembles the boxes of colonial times used for storing salt. The step often plunges from two and one-half stories in front to a single story in the rear.
