A secure and well-maintained roof means more than just your physical comfort. It symbolizes the entire concept of domestic shelter and psychological well-being. One of life’s basic necessities, along with food and clothing, is “a roof over one’s head”.
Yet most homeowners pay little or no attention to their roof—until it leaks. Even then, repairs are often put off until the problem is too great to be ignored.
Roof leaks, though, are more than just annoyances that must be remedied. They can be the cause of severe internal structural damage which is more difficult—and more costly—to repair.
THE BASIC FACTS
All roofs have five basic components:
- Roof structure: the rafters and trusses constructed to support the sheathing;
- Sheathing: the boards or sheet material which are fastened to the roof rafters to cover the house;
- Roof covering: shingles, tiles or sheets which protect the sheathing from the weather;
- Drainage: the features of the roof’s design, such as shape, slope, layout, etc., which affect its ability to shed water;
- Flashing: sheet metal or other material laid into the various joints and valleys of the roof to prevent water seepage
