Roofing Terms

  • Deck: Roofing materials are all applied to the deck, which is usually made from plywood or oriented strand board (OSB).
  • Dormer: Dormers are small structures that project from a sloped roof. They usually have a window.
  • Drip edge: The drip edge is attached to the edge of the roof. It channels water away from siding, eaves, or the deck.
  • Eave: The eave is a sloped roof’s horizontal lower edge.
  • Fascia: The fascia is found at the cornice’s outer edge. It can be a flat board, band, or face.
  • Felt/underlayment: A secondary layer of protection for the roof deck is called the felt or underlayment. It is a sheet of tar paper, which is an asphalt-soaked paper.
  • Fire rating: Roofing materials are rated according to their fire resistance. The three classes are A, B, and C. Class A is the most fire-resistant.
  • Flashing: Flashing is installed around intersections or projections including valleys, chimneys, vent pipes, and joints on vertical walls. It prevents water seepage.
  • Louvers: Louvers ventilate the area beneath a roof deck. They’re installed in a soffit or gable. They equalize air temperature and humidity.
  • Penetrations: Penetrations are anything that penetrates the roof deck, such as chimneys, stacks, pipes, and vents.
  • Rafters: The rafters are support framing to which a roof deck is attached.
  • Sheathing: Sheathing is attached to the rafters to cover a building.
  • Soffit: A soffit is the underside of the eaves.
  • Square: One square equals 100 square feet (10 by 10 feet). A roof’s surface area is measured in squares.
  • Valley: The intersection of two sloping roof surfaces.
  • Vapor retarders: Vapor retarders restrict the passage of water vapor through a roof system or wall.
