Roofing Terms
|
| Deck/sheathing: | The surface, usually plywood or oriented strand board (OSB), to which roofing materials are applied. | |
| Dormer: | A small structure projecting from a sloped roof, usually with a window. | |
 |
||
| Drip edge: | An L-shaped strip (usually metal) installed along roof edges to allow water run off to drip clear of the deck, eaves and siding. | |
| Eave: | The horizontal lower edge of a sloped roof. | |
 |
||
| Fascia: | A flat board, band or face located at a cornice's outer edge. | |
| Felt/underlayment: | A sheet of asphalt-saturated material (often called tar paper) used as a secondary layer of protection for the roof deck. | |
| Fire rating: | System for classifying the fire resistances of various materials. Roofing materials are rated Class A, B or C, with Class A materials having the highest resistance to fire originating outside the structure. | |
| Flashing: | Pieces of metal used to prevent the seepage of water around any intersection or projection in a roof system, such as vent pipes, chimneys, valleys and joints at vertical walls. | |
 |
||
| Louvers: | Slatted devices installed in a gable or soffit (the underside of eaves) to ventilate the space below a roof deck and equalize air temperature and moisture. | |
 |
||
| Oriented strand board (OSB): | Roof deck panels (4 by 8 feet) made of narrow bits of wood, installed lengthwise and crosswise in layers, and held together with a resin glue. OSB often is used as a substitute for plywood sheets. | |
| Penetrations: | Vents, pipes, stacks, chimneys-anything that penetrates a roof deck. | |
| Rafters: | The supporting framing to which a roof deck is attached. | |
 |
||
| Rake: | The inclined edge of a roof over a wall. | |
 |
||
| Ridge: | The top edge of two intersecting sloping roof surfaces. | |
| Sheathing: | The boards or sheet materials that are fastened to rafters to cover a house or building. | |
| Slope: | Measured by rise in inches for each 12 inches of horizontal run: A roof with a 4-in-12 slope rises 4 inches for every foot of horizontal distance. | |
 |
||
| Square: | The common measurement for roof area. One square is 100 square feet (10 by 10 feet). | |
| Truss: | Engineered components that supplement rafters in many newer homes and buildings. Trusses are designed for specific applications and cannot be cut or altered. | |
| Valley: | The angle formed at the intersection of two sloping roof surfaces. | |
 |
||
| Vapor retarder: | A material designed to restrict the passage of water vapor through a roof system or wall. | |
