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 roofing includes water-shedding types of roof coverings installed 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 since it keeps water from going into a roof assembly.
• Reinforcement-- reinforcement adds strength, leak resistance and dimensional stability to a membrane
• Emerging-- emerging is the element that safeguards the weatherproofing and reinforcement from sunlight and weather. Some emerging offer other benefits learn more such as increased fire resistance, improved traffic and hail resistance, and increased solar reflection ability
With some roof membranes, a component may perform more than one function.
There are six generic classifications of steep slope roof coverings.Asphalt shingles.
• Clay tile and concrete tile
• Metal roof systems for steep-slope applications
• Wood shakes and wood shingles
Steep-slope roof systems typically are composed of individual pieces or parts set up in shingle style. Steep-slope roof assemblies normally include 3 main parts:.
• Roof deck-- a roof deck is the structural substrate and normally is a wood-based product such as plywood or oriented hair board (OSB).
• Underlayment-- underlayment offers short-term security up until a roof covering is installed and provides a secondary weatherproofing barrier. Sometimes underlayment is referred to as "felt" or "paper.".
