The roof is among the most essential components of a structure, yet it is frequently taken for granted up until it falls under disrepair. Most roof systems last more than twenty years; however, routine examination and maintenance is needed to extend its life and keep total costs down. Residential home owners should pay more attention to the wear and tear on their roof systems, and make informed choices about roof system maintenance and replacement.
Buying a brand-new roof system is an important financial investment. Before you invest your money, spend some time finding out how to evaluate the roofer who might be doing the work.
All roofing contractors are not alike, and NRCA suggests you prequalify roofer to finish the job right the very first time. The
following guidelines will help in your choice:

• Insist on seeing copies of the professional's liability insurance protection and workers' payment certificates. Make certain the coverage is in effect through the duration of the task. (Note: U.S. employees' compensation laws differ by state. Consult your state's laws

Roof system types
Roof systems and products are normally divided into generic categories: low slope and high slope. Low slope roofing includes water impermeable, or weatherproof, types of roof membranes set up on slopes less than or equal to 3:12 (14 degrees). Steep slope roof includes water-shedding types of roof coverings set up on slopes exceeding 3:12 (14 degrees).
There are 5 generic categories 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.
Most low-slope roof membranes have three primary parts:
• Weatherproofing layer or layers-- the weatherproofing part is the most crucial component 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
• Emerging-- surfacing is the element that secures the weatherproofing and reinforcement from sunshine and weather condition. Some appearing supply other advantages such as increased fire resistance, enhanced traffic and hail resistance, and increased solar reflection ability
With some roof membranes, an element may perform 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
Steep-slope roof systems usually are composed of private pieces or components set up in shingle fashion. Steep-slope roof assemblies normally include 3 primary parts:.
• Roof deck-- a roof deck is the structural substrate and typically is a wood-based product such as plywood or oriented hair board (OSB).
• Underlayment-- underlayment supplies momentary defense until a roof covering is installed and supplies a secondary weatherproofing barrier. In some cases underlayment is described as "felt" or "paper.".
• Roof covering-- the roof covering is the external water shedding product.
