A well-made roof can add to the overall look of your home. And, depending on the structure, it can also add space to the attic. Finding a trustworthy contractor will be worth your time, as he will be able to advise you on the materials that are best suited for the weather conditions in your area. Roofs are made up of the following parts.
A dormer is built around a window and projects from the roof. It is often used in attics to add light and a pleasing design to the house.
A truss is a triangular wood structure that supports the roof and gives it added strength. It takes several trusses to build the structure that supports the roof.
A rafter is a parallel beam that supports the roof, and is part of the truss. They are the main frame of the roof.
Sheathing, also called decking, covers the rafters, and tar paper is laid on top of it. Plywood is the most common material used for decking. Once the tar paper is installed to the sheathing, shingles are nailed to the roof.
Tar paper is the more common term for underlayment. Tar paper protects the decking from moisture and other weather elements.
A drip edge is constructed at the bottom of the roof. It is designed to direct water to run off and away from the home.
