The pitch of a roof refers to the steepness or slope of the roof surface. It is typically expressed as a ratio of vertical rise to horizontal run. For example, a roof with a 4:12 pitch rises 4 inches vertically for every 12 inches horizontally.



Underlayment is a protective barrier installed beneath the roofing material to provide an additional layer of waterproofing and protection against moisture. It is typically made of felt or synthetic materials and serves to prevent water from seeping into the roof deck.



Flashing is a thin, impervious material (often metal) that is installed around roof penetrations, such as chimneys, vents, or skylights, to prevent water from seeping into the roofing system. Flashing helps redirect water away from vulnerable areas and ensures a watertight seal.



The eaves of a roof are the lower edges that overhang the face of a wall. Eaves serve to protect the exterior walls from water damage by directing rainwater away from the building and foundation. Eaves also contribute to the aesthetics of a roof and provide shade and protection.
