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.
CanopyA part of the roof structure that overhangs an entrance or a door.
Cant StripA 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 FlashingCap 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 SheetUsed 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 ValleyA 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 StripA strip of metal or other material that is used to close gaps in between membranes or other joints.
CopingA piece of metal, masonry or stone that is used to protect the top of part of a wall from weather and water.
Counter flashingA shaped piece of metal sheeting that is used to cover and weatherproof the upper edge of the base flashing.
CupolaA small roofed structure that sits on top, usually in the center, of a larger roofed structure.
CuppingWhen 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.
