Roofing Terms   Regular or 3-Tab Shingles:  Regular roof shingles are called “3-tab”, for the 3 tab/flaps with quarter-inch grooves between them in each panel. They run in flat, even rows as opposed to the textured and layered look of architectural shingles. Regular shingles have an average 15 to 20 year life.   Architectural Shingles: 
A premium grade strip shingles made with fiberglass mat and asphalt that are laminated, or textured, to create a three-dimensional effect; also called laminated shingles. Architectural shingles start with a heavier mat base, typically fiberglass that has been coated with asphalt. Multiple layers are then overlapped and laminated together to create a thicker and more distinctive, textured appearance. An architectural shingle has a 24 to 30 year life, with some super-premium grades that are rated for up to a 40 year lifespan.

Also, architectural shingles come in a wider variety of colors, subtly variegated color patterns, have greater resistance to uplift in a windstorm, and have a heavier granule covering for greater resistance for hail damage.    All of this comes at a premium price, of course. Typically, an architectural shingle roof will cost about 25% more. But you are rewarded for the extra investment with a 50% longer lifespan and a better looking roof (that all-important curb-appeal boost it give your home).   Square: 
A roofer’s term for 100 square feet of roof area.   Deck:
The substrate over supportive framing to which roofing material is applied; also called decking or sheathing. The deck normally is plywood, OSB or 1x lumber.   Felt:
Material of interwoven fibers saturated with asphalt and used as a protective under layer between shingles and decking; also called tarpaper.   Drip Edge:
Flashing made of aluminum or other non-corrosive material that is placed along the eaves and rake edges at a 90º angle to let water runoff drop clear of fascia and into the gutters.   Ice/Leak Barrier:
A watertight barrier used to seal water out in valleys, around chimneys, skylights, plumbing vents and any other roof penetration. A self-adhering and self-sealing membrane applied to the roof deck and designed to protect against water infiltration from Ice buildup or wind-driven rain. The ice barrier will seal around nails that penetrate it; also called water barrier.   Flashing:
Metal or other flexible material used to seal the roof and prevent leaks around any projection or intersection, such as pipes, chimneys, dormers, valleys or adjoining walls.   Plumbing Boot:
A prefabricated covering, usually of flexible material, used to seal around a penetration; also called a pipe boot or roof jack.   Ridge:
The horizontal external angle formed by the intersection of two sloping roof planes, i.e. where the two sides of a roof meet at the highest point.   Roof Ventilation:
A static, wind or power-operated system for removing hot air and moisture from the air under your roof. Includes ridge vents.   Ridge Vent:
The best type of roof exhaust vent that ventilates the attic along the ridge or hip line where the roof deck has been cut back; works in conjunction with soffit vents under the eaves or a starter edge vent; also called an exhaust vent. NOTE:
Proper balance of intake and exhaust ventilation is a must for overall protection of your shingles. If this balance isn’t maintained, it will reduce the lifespan of your shingles.   Fascia:
Vertical roof trim located along the perimeter of a building, usually below the roof level, to cover the rafter tails at the eaves and to seal off the top of the siding along the rake; also called gutter boards.   Soffit:
The underside of the eaves, or roof overhang, which can be enclosed or exposed.   Soffit Vent:
An intake vent in the soffit area of the house that provides attic venting at a lower portion of the roof deck and good circulation with other forms of venting such as ridge or roof vents; also called an intake vent.   Starter Edge Vent:
A vent that is installed on top of the roof just above the gutter. This vent is a lower cost option than installing soffit vents. These vents are not needed if soffit vents are installed or existing. This allows the air to enter the attic at the low end and escape at the highest point (ridge); also called an intake vent.   Eave:
A roof edge that extends past the exterior wall line at the bottom of a slope.   Rake:
The inclined edge of a sloped roof over a wall from the eave to the ridge, and usually perpendicular to the eave and ridge.   Hip:
The external angle formed by the intersection of two sloping roof planes; from the ridge to the eaves.   Valley:
The internal angle formed by the intersection of two sloping roof planes running from the eaves to the ridge, allowing water to run off.   Flat Roof:
A roof with a pitch of less than two feet of rise over a twelve-foot run (2/12); this type of roof needs a sealed system installation.   Low Slope Roof:
A roof with a pitch having two or three feet of rise over a twelve foot run (2/12 or 3/12). This type of roof must be installed using ice/leak barrier instead of felt paper or a sealed roof system.   Shed Roof:
A roof containing only one sloping plane; a single-pitch roof, with no hips, ridges, valleys or gables; also called a half gable.   Pitch Changes:
The variation in the degree of roof incline, which is expressed as the ratio of the rise to the span, in feet.   Rafter:
The structural member supporting the deck and roof system components, extending from the downslope perimeter to the ridge or hip.
