A roof is much more than just the decorative top of a building. A roof provides protection from the elements and precipitation helps drain water away from a structure and provides insulation that helps keep the interior of a building warm or cool depending on the season. In many cases with purchased house plans the details of the roof construction including rafter design are included. For example 1 8 1 one eighth inch equals one foot.

The most commonly used types of pitched roof construction are the gable the hip the intersecting and the shed or lean to. An example of each is shown in figure 2 1. Use construction nails 6 in 15 cm apart to secure the plywood around the outer perimeter and along each support. Construction plans blueprints are scaled down representations of the final project at a ratio of the actual size.

Put roof sheathing on top of your roof. Also different architectural styles will use the same type of roof. Another common design in the northeast is the saltbox which is a gable roof with one longer side. These days cut ups or roofs with a lot of valleys dormers and other features are increasingly popular.

Use 1 2 in 1 3 cm plywood to cover the entire surface of your roof. Some roofs actually slope in several directions ensuring optimal water runoff. You can do this with a foam layer that exactly fits your roof. Gable a gable roof has a ridge at the center and slopes in two directions.

This will help you create a flat roof framing plan. Place a piece of the plywood on the bottom corner of your roof making sure the edges are on a rafter beam. Flat roofs are always built at a slight incline at least 1 8 inch per foot.
