Roof construction plans.

The most commonly used types of pitched roof construction are the gable the hip the intersecting and the shed or lean to. Place a piece of the plywood on the bottom corner of your roof making sure the edges are on a rafter beam. Intricate roofs have many parts that incorporate several of the basic roof designs such as a gable roof sitting atop a gambrel or variations of the gable valley roof design using one or a variety of different types of roof trusses also see our very detailed diagrams showing the different parts of a roof truss. A roof is much more than just the decorative top of a building.

Put roof sheathing on top of your roof. In many cases with purchased house plans the details of the roof construction including rafter design are included. Another common design in the northeast is the saltbox which is a gable roof with one longer side. When framing a flat roof you will need to create a slight incline.

Flat roofs are always built at a slight incline at least 1 8 inch per foot. For example 1 8 1 one eighth inch equals one foot. This will help you create a flat roof framing plan. Gable a gable roof has a ridge at the center and slopes in two directions.

An example of each is shown in figure 2 1. 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. Use construction nails 6 in 15 cm apart to secure the plywood around the outer perimeter and along each support. Use 1 2 in 1 3 cm plywood to cover the entire surface of your roof.

These days cut ups or roofs with a lot of valleys dormers and other features are increasingly popular. Some roofs actually slope in several directions ensuring optimal water runoff. You can do this with a foam layer that exactly fits your roof.
