When a roofing contractor is working on your home, having some knowledge of the terms they use can be beneficial. In this post, Stapleton Roofing shares a list of commonly used terms within the roofing industry.

Commonly Used Roofing Terms and Their Meanings

Roof Pitch

Pitch is the measure of a roof’s slope. Roof pitch is intended to allow proper flow of rain. While categories are not properly defined, roof pitch may be classified as:

  • Low Slope

  • Medium Slope

  • Steep Slope

  • Flat

Roof Flashing

These are the pieces of metal used to avoid water leakage into your home. Roof flashing is typically installed around any intersection in a roof like the chimneys, adjoining walls, vent pipes, valleys and dormers. Ask a trusted local roofing company like Stapleton Roofing to make sure your roof flashings are secure.

Roof Deck

Decks are the foundation of your roof. They are the base that is placed against your attic to conceal the rafters and support the total weight of the roofing materials. Roof decks must be strong enough to support all the roofing materials that are fastened to it and reliable enough to cope with the force of natural elements and constant use. If installed correctly, a roof deck will dramatically increase the longevity of your roofs.


This refers to materials that have waterproofing capabilities. They are usually placed on flat roofs to avoid water leaks and channel water away from the roof itself.


This is the base layer of the roof and usually found between the shingles and roof deck. Underlayments can be waterproof or water-resistant depending on the material and quality.
