Glossary  of Roofing Terms

At Century Roofing Limited, we hope to educate our homeowners on any terms undefined. We’ve compiled a handy list of some of the most common roofing terms so that you can understand every step of the roofing process.

  • Canopy

    A part of the roof structure that overhangs an entrance or a door.
  • Cant Strip

    A three-sided strip of wood cut on an angle to provide a sloped transition between the roof deck and an adjacent wall. Cant strips help with waterproofing by closing the gap between the roof deck and any walls.
  • Cap Flashing

    Cap flashing is a form of flashing that keeps water from getting into the upper edges of the membrane base or other types of flashing.
  • Cap Sheet

    Used in built-up roofing, a cap sheet is the topmost roofing sheet that serves to protect the lower layers of a roof membrane. It’s usually coated with a granular substance and can help to extend the life of the roof.
  • Closed Valley

    A valley is the line where two separate sections of the roof meet and drain water off the roof. A closed valley is when the shingles on one side completely cover the shingles on the other side.
  • Closure Strip

    A strip of metal or other material that is used to close gaps in between membranes or other joints.
  • Coping

    A piece of metal, masonry or stone that is used to protect the top of part of a wall from weather and water.
  • Counter flashing

    A shaped piece of metal sheeting that is used to cover and weatherproof the upper edge of the base flashing.
  • Cupola

    A small roofed structure that sits on top, usually in the center, of a larger roofed structure.
  • Cupping

    When shingles start to warp at the edges, forming a cup shape. Cupping is usually a sign that shingles contain a manufacturer’s defect or were installed incorrectly.
