Roofing Glossary

Terms the Roofers Use

Words like “exposure,” “rake,” and “valley” are used freely in the roofing industry, but they don’t always mean the same thing to homeowners. Looking at them through a roofer’s eyes, though, might streamline the project you undertake. Here are some of the more commonly used terms:

Built-up roof

A flat or slightly sloped roof surfaced with alternating (or built up) layers of roofing felt and hot mopped asphalt, and a layer of gravel or crushed rock on top.

Butt

The exposed end of a shingle or shake.

Courses

The horizontal rows of roofing material, laid successively from the eave to the ridge of the roof.

Deck

The structural nailing base for the roof surface, usually composed of wood or plywood sheathing and felt underlayment.

Drip edge

A type of flashing made of thin strips of metal or plastic that extend the length of the eaves and rakes to facilitate water runoff.

Eave

The edge of the roof that projects beyond the house wall.

Exposure

The portion of each shingle or tile exposed to the weather.

Fascia

Wood or other trim covering the ends of the rafters.

Flashing

Waterproofing materials usually metal, that connect roof shingles or tiles to chimneys, valleys, vent pipes, vertical walls, eaves, and rakes.

Gable

A type of roof with two slopes meeting at a horizontal ridge. Also, the triangular area formed by such a roof.

Hip

A downward sloping intersection of two roof planes that extends from the ridge to the outside corner of the house. Also, a type of roof.

Rake

The edge of a pitched roof at the gable end.

Ridge

The top edge of the roof, where two roof slopes meet in a horizontal line.

Sheathing

Boards or plywood sheets that form the nailing base for roofing shingles or tiles.

Slope (or pitch)

The number of inches of verticle rise of the roof over a horizontal distance of 12 inches; a “4 in 12” roof has a slope that rises 4 inches over a 12-inch run.

Soffit

The underside of the rafters and roof at the eaves.

Square

Unit of measure equaling 100 square feet, used as a basis for measuring roof area. Also, the amount of roofing material, allowing for overlapping, needed to cover 100 square feet of roof.

Underlayment

The material, usually asphalt-saturated roofing felt, used to cover deck sheathing before the roof surface is put down.

Valley

The junction where two downward sloping roofs meet at an angle, an important channel for water runoff.
