Understanding common roofing jargon will help you as a homeowner choose tetőfedő materials that are suitable for the design of your home and the area where you live. Additionally, it will clarify the terms of your contract with your roofing expert and the status of your project.
Here are some essential terms related to roofing:
Asphalt: A waterproofing agent used while producing roofing materials.
An asphalt-based sealer used to attach roofing components together is called asphalt plastic roofing cement. Also known as bull, mastic, roof tar, flashing cement, and tar.
Back surfacing: The application of granular material on the underside of shingles to prevent adhering during transport and storage.
Base flashing: The section of the flashing used to send water onto the roof that is attached to or rests on the deck.
Built-up roof: glued together asphalt and ply sheets in several layers.
The butt edge is the shingle tabs’ bottom edge.
Fill a joint with caulk to stop leaks.
Closed valley: Shingles cover the valley flashing.
Coating: The exterior roof surface is covered in a viscous asphalt coating to safeguard the roof membrane.
A pre-formed flange known as a collar is used to cover a vent pipe and seal the roof around the pipe’s opening. Likewise known as a vent sleeve.
Application of roll roofing using the concealed nail method, in which all nails are hidden by an overlapping course of cement.
The counter flashing prevents water from leaking behind the base flashing by being fastened to a vertical surface above the roof’s plane.
Course: A shingle row that may run vertically, diagonally, or both.
Cricket: A peaked water diverter that is erected at the base of a chimney to divert water and prevent snow and ice from building up.
Deck: The surface laid over the supporting parts of a structural structure and to which a roof system is attached.
Double coverage: An asphalt roof with two layers of roofing material covering the deck because the lapped area is at least two inches wider than the exposed portion.
A downspout is a conduit used to drain water from roof gutters. also known as a captain.
Drop edge: An L-shaped flashing used along eaves and rakes to allow water to drip away from underlying building and into the gutters.
Eave: The portion of the roof that spreads outward and does not hang directly over the building’s interior or exterior walls.
Application of roll roofing using the exposed nail technique involves driving nails into the overlapping courses of roofing. The environment is exposed to nails.
Fascia: A wood trim board used to conceal the sheathing and rafters of the roof’s cut ends.
Roll roofing materials are described as felt: Fibrous material used as an underlayment or sheathing paper.
Flashing: Metal or roll roofing pieces that are used to provide a watertight seal around vent pipes, chimneys, neighbouring walls, dormers, and valleys.
Gable: The outer wall’s end that forms a triangle point at the roof’s ridge.
Granules: Crushed rock that has been burned and ceramic-coated and used as the top layer of roofing materials made of asphalt.
The gutter is the trough that collects rainwater and directs it to the downspouts. commonly affixed to the fascia.
Head lap: The upper border of roofing felt or shingles overlapped.
Hip: The fold or vertical ridge created when two sloping roof planes connect. spans the ridge to the eaves.
Ice dam: A condition when melted snow on the overhang thaws and then re-freezes, causing water to back up at the eave sections. can push water behind tiles, resulting in leaks.
Individual shingles that mechanically connect to one another to improve wind resistance are called interlocking shingles.
Laminated shingles: Strip shingles with an added layer of thickness constructed of two distinct pieces laminated together. additionally known as architectural and three-dimensional shingles.
Lap: The area where two rolls of shingles or other materials overlap each other during application.
A mansard roof is a structure with a nearly vertical roof plane attached to a peak-to-peak roof plane with a smaller slope. no gables are present.
Mineral stabilisers: Asphalt coatings can be strengthened and given greater fire and weather resistance by adding finely crushed limestone, slate, traprock, or other inert materials.
Nesting is a roofing technique in which the top edge of the fresh asphalt shingle is pressed up against the bottom edge of the tab from the previous layer of shingles.
Pitch is the percentage of roof inclination represented as the difference between the rise and span in feet.
Roof pitches of less than 30 degrees are referred to as low slopes.
Roof pitches ranging between 30 and 45 degrees are referred to as “normal slopes.”
Roof pitches of greater than 45 degrees are considered steep slopes.
Roof structure’s supporting framing, or rafters, are located directly below the deck and serve as anchor points for the roof sheathing.
Rake: The sloping edge of a roof that extends from the eave to the ridge over a wall. They might be short or long.
Ridge: The horizontal exterior angle created by the meeting of two sloping roof sides at the hip or dormer’s highest point.
Run is the horizontal distance, or one-half of the span, between the eaves and a point exactly beneath the ridge.
Selvage: The area of roll roofing that was overlapped when the roof covering was applied in order to provide double coverage.
Sheathing: The term for exterior-grade boards used as roof decking.
A shed roof is a single roof plane devoid of any gables, ridges, hips, or valleys and is not attached to any other roofs.
Slope: The ratio of the rise in inches to the run in feet, which represents the angle of the roof.
Roll roofing having a smooth surface that is covered in ground talc or mica rather than granules (coated).
The finished underside of the eaves that runs from the fascia to the siding and conceals the underside of an overhang is known as the soffit.
A roof-penetrating vent pipe is referred to as a soil stack.
Span is the horizontal measurement between eaves.
Specialty eaves flashing membrane: A self-adhering waterproofing underlayment for shingles created to guard against water intrusion from ice dams or wind-driven rain.
Starter strip: The initial course of shingles is installed using an asphalt roofing application at the eaves.
Tab: The area of strip shingles between the cutouts that is exposed to the elements.
Telegraphing: Unevenly installed shingles that exhibit distortion.
Truss: A structure for support in the building of wide span roofs made of a combination of beams, bars, and ties, typically arranged in triangular units.
The level of fire and/or wind resistance of asphalt roofing is indicated by the UL mark, which is displayed on packaging.
Underlayment: An additional layer of rolled asphalt-based materials placed beneath the primary roofing material before the shingles are put on to protect the deck.
Valley: The internal angle created when two sloping roof surfaces cross each other to enable water runoff.
Any substance that blocks the flow of water vapour or water through it is a vapour barrier or retarder.
Any device installed on the roof that serves as an air outlet to ventilate the roof deck’s underside.
