Roofing contractor in Milton, Gulf Breeze, Brent, FL & the surrounding areas.

Deck/Sheathing: The surface, usually plywood or oriented strand board (OSB), to which roofing materials are applied.

Dormer: A small structure projecting from a sloped roof, usually with a window.

Drip Edge/Eave Metal: An L-shaped strip (usually metal) installed along roof edges to allow water runoff to drip clear of the deck, eaves and siding.

Eave: The horizontal lower edge of a sloped roof.

Fascia: A flat board, band or face located at a cornice’s outer edge.

Felt/Underlayment: A sheet of asphalt-saturated material (often called tar paper) used as a secondary layer of protection for the roof deck.

Flashing: Pieces of metal used to prevent the seepage of water around any intersection or projection in a roof system, such as vent pipes, chimneys, valleys and joints at vertical walls.

Penetrations: Vents, pipes, stacks, chimneys—anything that penetrates a roof deck.

Rafters: The supporting framing to which a roof deck is attached.

Rake: The inclined edge of a roof over a wall.

Ridge: The top edge of two intersecting sloping roof surfaces.

Ridge Vent: Roof component which is installed over an area of ridge where the sheathing has been cut approximately 1.5 – 2.5 inches away from the center of the ridge to allow for proper attic ventilation.

Slope: Measured by rise in inches for each 12 inches of horizontal run: a roof with a 4-in-12 slope rises 4 inches for every foot of horizontal distance.

Square: The common measurement for roof area. One square is 100 square feet (10 by 10 feet).

Truss: Engineered components that supplement rafters in many newer homes and buildings. Trusses are designed for specific applications and cannot be cut or altered.
