Roof system types
Roof systems and products are usually divided into generic classifications: low slope and steep slope. Low slope roofing includes water impermeable, or weatherproof, types of roof membranes installed on slopes less than or equal to 3:12 (14 degrees). Steep slope roof consists of water-shedding kinds of roof coverings set up on slopes exceeding 3:12 (14 degrees).
There are five generic classifications of low slope roof membranes or systems.
• Built-up roof (BUR) membranes
• Metal panel roof systems for low-slope applications
• Polymer-modified bitumen sheet membranes
• Single-ply membranes
• Thermoplastic membranes (e.g., PVC, TPO)
• Thermoset membranes (e.g., EPDM)
• Spray polyurethane foam-based (SPF) roof systems.
Many low-slope roof membranes have three principal elements:
• Weatherproofing layer or layers-- the weatherproofing element is the most essential aspect due to the fact that it keeps water from getting in a roof assembly.
• Support-- support includes strength, leak resistance and dimensional stability to a membrane
• Surfacing-- surfacing is the component that protects the weatherproofing and reinforcement from sunlight and weather. Some emerging offer other benefits such as increased fire resistance, improved traffic and hail resistance, and increased solar reflection ability
With some roof membranes, an element might carry out more than one function.
There are 6 generic categories of high slope roof coverings.Asphalt shingles.
• Clay tile and concrete tile
• Metal roof systems for steep-slope applications
• Wood shakes and wood shingles

• Roof deck-- a roof deck is the structural substrate and generally is a wood-based product such as plywood or oriented hair board (OSB).
• Underlayment-- underlayment provides temporary security up until a roof covering is set up and supplies a secondary weatherproofing barrier. Sometimes underlayment is referred to as "felt" or "paper.".
