Built-up roof: Multiple levels of asphalt and ply sheets fused together.

Butt advantage: The bottom edge in the shingle navigation bars.

Caulk: To load a joint in order to prevent leaks.

Sealed valley: The valley flashing is protected by shingles.

Coating: A layer associated with viscous asphalt placed on the outer roofing surface to safeguard the roof membrane.

Collar: Pre-formed flange placed over a vent pipe to seal the roof structure around the port pipe opening. Also called as a vent outter.

Concealed nail approach: Application of throw roofing in which usually all nails are usually covered by the cemented, overlapping program.

Counter flashing: Of which portion of the flashing attached in order to a vertical area above the airplane of the roof top to stop water coming from migrating behind the base flashing.

Study course: Row of shingles that can operate horizontally, diagonally or perhaps vertically.

Cricket: A peaked water diverter installed at typically the back of the chimney to stop accumulation of ideal and ice and deflect water.

Terrace: The top surface that a roof strategy is applied, surface installed over the particular supporting framing people.

Double coverage: Concrete roofing whose lapped portion reaches very least two inches larger than the uncovered portion, resulting in two layers involving roofing material above the deck.

Downspout: A pipe with regard to draining water coming from roof gutters in order to drain. Also referred to as an innovator.

Drip advantage: L-shaped flashing employed across the eaves and even rakes to let water run-off straight into the gutters and also to drip clear associated with underlying construction.

Eave: The part of the roof top that overhangs or even extends outward and even is not immediately within the exterior wall surfaces or perhaps the buildings rooms.

Exposed nail approach: Using roll roof covering where nails are driven into typically the overlapping course of roof covering. Nails are exposed to the elements.

Fascia: A new wood trim table used to cover the cut comes to an end with the roof's rafters and sheathing.

Gable: The conclusion of an external wall that involves a triangular level at the ridge of a sloping roofing.

Granules: Ceramic-coated and fired crushed mountain that may be applied since the top area of asphalt roof covering products.

Gutter: The trough that channels water in the eaves to the downspouts. Usually attached to be able to the fascia.

Head lap: An overlapping of shingles or even roofing felt from their upper advantage.

Hip: The fold or vertical shape formed by the particular intersection of 2 sloping roof planes. Runs through the ridge to the eaves.

Ice dam: Situation forming water backing up at the eave areas by typically the thawing and re-freezing of melted snow on the overhang. Can force drinking water under shingles, leading to leaks.

Interlocking shingles: Individual shingles that mechanically fasten to each other to provide wind resistance.

Laminated shingles: Strip shingles made of two distinct pieces laminated along to create more thickness. Also known as three-dimensional and new shingles.

Lap: Surface area where one shingle or roll overlaps with another in the course of the application process.

Mansard roof: Some sort of design with a nearly vertical roof aircraft connected to some sort of roof plane of less slope at its peak. Is made up of no gables.

Mineral stabilizers: Finely surface limestone, slate, traprock or other inert materials added to be able to asphalt coatings with regard to durability and increased resistance to flames and weathering.

Nesting: A method associated with reroofing, installing the second layer of recent asphalt shingles, where the top edge with the new shingle is definitely butted against the particular base of the existing shingle tabs.

Pitch: The level of roof incline expressed as the ratio in the rise, in ft, to the duration, in feet.

Low Slope - Roof pitches that will be less than 35 degrees.

Normal Slope - Roof pitch that are between 30 and forty-five degrees.

Steep Mountain - Roof pitches which might be more as compared to 45 degrees.

Rafter: The supporting framework that makes the roof structure; right away beneath the deck; the roof sheathing will be nailed to the rafters.

Rake: Typically the inclined edge associated with a sloped roof structure over a wall structure from the eave to the ridge. These people can be close or extended.

roof restoration : The horizontal outside angle formed simply by the intersection involving two sloping factors of a roof structure at the top point of typically the roof, hip or perhaps dormer.

Run: The particular horizontal distance in between the eaves along with a point directly beneath the ridge; or half the span.

Selvage: That portion involving roll roofing overlapped by application associated with the roof covering to obtain double coverage.

Sheathing: Outside grade boards employed like a roof terrace material.

Shed roof structure: Just one roof airplane with no hips, ridges, valleys or gables, not connected to any other roofing.

Slope: The diploma of roof incline expressed as being the percentage of the rise, in inches, towards the run, in foot.

Smooth-surfaced roofing: Roll roofing that is usually covered with surface talc or briciolo rather than granules (coated).

Soffit: The done underside of the eaves that extends from the fascia to the exterior and hides typically the bottom of an overhang.

Soil stack: A vent pipe that will penetrates the top.

Period: The horizontal length from eaves to be able to eaves.

Specialty eaves flashing membrane: A new self-adhering, waterproofing shingle underlayment built to safeguard against water infiltration due to snow dams or wind driven rain.

Beginner strip: Asphalt roof covering applied at the eaves as being the 1st course of shingles installed.

Tab: The next thunderstorm exposed surface involving strip shingles between your cutouts.

Telegraphing: Shingles installed over an uneven surface of which show distortion.

Truss - A combination of beams, night clubs and ties, usually in triangular units to form a new framework for support in wide period roof construction.

UL label: Label exhibited on packaging to be able to indicate the levels of fire and/or wind resistance associated with asphalt roofing.

Underlayment: A layer involving asphalt based folded materials installed beneath main roofing material before shingles happen to be installed to offer additional protection intended for the deck.
