Roofing Terms

AGGREGATE ā€“ A crushed rock mixture used as a top layer for some commercial flat roofs.

BLISTERING - Bubbles or pimples in roofing materials after work is completed. In shingles, blisters are either moisture under the material or moisture trapped inside the shingle itself.

BUILT-UP ROOF - A type of commercial flat-roof applied by installing multiple layers of ply-sheets and asphalt covering. The top coat is given a coating of bitumen imbedded with aggregate layers.

COMPOSITE ROOFING - Roofing shingles made with a mixture of plastic and minerals to produce a superior shingle. The shingles are driven into the underlying course of roofing and covered by an overlapping course, which leaves nails unexposed to the elements.

CRICKETS - A peaked water diverter installed behind chimneys and other large roof projections to effectively divert water and prevent build up of snow and ice.

CUPPING ā€“ Tendency for shingles to cup or curl when improperly installed over an existing roof or overexposed. Occasionally caused by manufacturer defect rather than improper installation.

DRIP-EDGE ā€“ A non corrosive lip that keeps shingles up off of the deck at edges, and extends shingles out of over eaves and gutters to prevent water from backing up under shingles.

FLASHING - Material used to waterproof and prevent seepage around any projections or intersections throughout the roof deck

GABLE ROOF - Traditional roof style, two equal-angled roof planes meeting at a ridge line with gables on either side.

GAMBREL ROOF - A type of roof with a gable on either end and two different angled roof planes meeting at a ridge line. The lower plane has a steeper slope than the upper plane.

HIP ROOF - A roof containing no gables with four equal-angled roof planes coming together at a peak and four separate down-slope ridges.

LOW SLOPES - Roof pitches less than four inches per foot of down slope are considered low-sloped roofs. Special installation practices must be used on roofs of four and two inches per foot.

MANSARD - A roof with two different angled roof planes meeting at a ridge. Often the lower plane has a much higher pitch than the upper plane, sometimes nearly vertical.

SOFFIT VENTILATION - Intake ventilation installed under the finished eaves, or at the edge of the roof.

STEEP-SLOPE ROOFING - Generally all slopes higher than four inches per foot are considered steep slopes.

UNDERLAYMENTS - Asphalt-based rolled materials installed under the main roofing material to serve as added protection for the roof deck.

    "These guys were very professional, they finished their work in one day, and had a dedicated safety person on site at the beginning of the installation. When they left, I could not even tell they had been there."

You will not regret it."
