Although a roof is, overall, basic in its form and function, it is comprised of several various components. (For more explanation of smaller detail components, see Glossary, p. 26. in the Insider's Guide to roofing)
Regardless of Design or the Type of building they top, all roofing systems have five basic components:
- Structure: The rafters and trusses that support the decking.
- Decking/sheathing: The boards or sheet materials that are fastened to the roof rafters to cover the house. Underlayment: Sheets of asphalt-saturated material. Used as a second layer of protection for the roof decking.
- Roof covering: Shingles, tiles, etc., that protect the decking from weather.
- Drainage: The features of the roof's design such as slope, shape, layout, etc., that determine its ability to shed water.
- Flashing: Sheet metal laid into the various joists and valleys of a roof system to prevent water leaks.
