Roof system types
Roof systems and products are usually divided into generic categories: low slope and steep slope. Low slope roof includes water impenetrable, or weatherproof, kinds of roof membranes installed on slopes less than or equal to 3:12 (14 degrees). Steep slope roof consists of water-shedding types of roof coverings set up on slopes surpassing 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.
A lot of low-slope roof membranes have 3 primary elements:
• Weatherproofing layer or layers-- the weatherproofing part is the most crucial component due to the fact that it keeps water from going into a roof assembly.
• Reinforcement-- reinforcement includes strength, puncture resistance and dimensional stability to a membrane
• Surfacing-- emerging is the element that safeguards the weatherproofing and support from sunlight and weather condition. Some surfacing provide other advantages such as increased fire resistance, enhanced 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 made up of specific pieces or parts installed in shingle style. Steep-slope roof assemblies generally 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 strand board (OSB).
• Underlayment-- underlayment supplies short-lived defense till a roof covering is set up and offers a secondary weatherproofing barrier. Sometimes underlayment is referred to as "felt" or "paper.".
