The Asphalt Roofing Manufacturers Association, a trade association for North American manufacturers of asphalt roofing.
Bubbles that may appear on the surface of asphalt roofing after installation due to moisture “cooking” out of the asphalt.
The lower edge of the shingle tabs.
Pre-formed flange placed over a vent pipe to seal the roof around the vent pipe opening. Also called a vent sleeve.
The change of water from vapor to liquid when warm, moisture-laden air comes in contact with a cold surface.
A framed unit projecting through the sloping plane of a roof.
The horizontal, lower edge of a sloped roof.
Eave Flashing/Drip Edge
Lengths of roofing material (usually metal or copper) applied at the eaves to help prevent damage from wind-driven rain water back-up
Pieces of metal/copper (in steep slope applications) to prevent seepage of water into a building around any intersection or projection in a roof such as vent pipes, chimneys, adjoining walls, dormers and valleys. Other types of flashings can be used in low slope roofing.
A simple two-sided roof above a gable.
A type of roof containing two sloping planes of different pitch on each side of the ridge. The lower plane has a steeper slope than the upper. Often contains a gable at each end.
The trough that channels water from the eaves to the downspouts.
Shingles that have the appearance of a hexagon after installation.
A roof where all four sides slope downwards from the peak. Contains no gables.
Shingles created by mating two layers of shingles together to create a more robust and pleasant visual. Also called dimensional or architectural shingles.
That portion of the roof structure that extends beyond the exterior walls of a building.
A flashing mechanism used to provide a water tight seal around roof pipes that can be tied into the field roof service.
Roofing application method in which shingle courses are applied vertically up the roof.
The supporting framing member immediately beneath the deck, sloping from the ridge to the wall plate.
The process of removing existing roof coverings and replacing with a new roofing system.
The uppermost, horizontal external angle formed by the intersection of two sloping roof planes.
The vertical distance from the eave line to the ridge.
The degree of roof incline expressed as the ratio of the rise, often in inches, to the run, in inches. For example, a roof slope of 4/12 has a 4 inch rise every 12 inches run.
The distance between the bottom of the first shingle course and the start of the fascia or decking over which it hangs.
Styrene-Butadiene-Styrene, which is a synthetic polymer that is mixed with asphalt in some products to increase the flexibility and other attributes of the products.
A roof containing only one sloping plane. A shed roof has no hips, ridges, valleys or gables.
The finished underside of the eaves.
The horizontal distance from eave to eave.
Any material used to prevent the passage of water vapor.
