Roofing Terminology:
When investigating and selecting roof systems and roof installation professionals it is helpful to understand commonly used roofing terms.
Drainage: Drainage is the aspect of a roof system which allows the roof to shed water. It refers to design features such as slope, shape and layout.
Fasteners: The mechanisms used to attach a roof covering to the building are called fasteners. Nails are the most common type of fasteners used in roof replacement and roof installation, however certain roof systems require alternative types of fasteners.
Felt Paper: This term refers to the underlayment component of the roof assembly. It provides secondary waterproofing and weatherproofing for the roof.
Flashing: The flashing consists of sheet material and other materials installed at various points to prevent water from seeping through the roof to the underlying structures.
Ice Dam Membrane: This is an additional part of roof assembly underlayment. It is not routinely installed except in climates known for extend periods of extreme cold. The purpose of an ice dam membrane is to protect the roof system from damage caused when snow melts and then refreezes at the edges of the roof.
Pitch: The pitch refers to the angle of a roof. A roof referred to at pitched is considered to have a steep slope. The pitch of roof is usually given in degrees.
Rafters: The set of sloping beams which form the framework and supports for pitched roofs are called rafters.
Roof Assembly: The roof assembly is composed of the three components; a roof deck, an underlayment and a roof covering.
Roof Covering: The outermost layer, which provides primary water-shedding and waterproofing is referred to as the roof covering.
Roof Deck: This is an underlying structural layer frequently made of plywood or oriented strand board.
Roof Structure: The roof structure is made up of rafters and trusses constructed to support the outermost layer of the home or building.
Roof System: The complete roof system composed of the roof structure, sheathing, roof covering, flashing and drainage.
Sheathing: The sheathing are the boards or sheet materials which connect to the rafters and make up the covering of the structure.
Slope: The slope of a roof refers to its steepness. Flat-roofs have no slope, low-slope roofs are easy to walk on, medium-slope roofs are probably the most commonly seen roof type, and steep-slope roofs are very distinctive looking and would be difficult to walk on. The slope of a roof is measured in degrees.
Thermal Shock: Thermal shock is the label used to describe roof system damage resulting from rapid temperature change.
Truss: The rigid framework designed to support a roof structure is called a truss.
Underlayment: Also referred to as “paper” or “felt” the underlayment provides temporary weatherproofing to the roof deck and underlying roof structures during roof installation. After roof installation is complete the underlayment functions as a secondary layer of waterproof and weatherproofing for the roof system.
