The roof is among the most important parts of a structure, yet it is often not thought of until it falls into disrepair. The majority of roof systems last more than 20 years; nevertheless, regular assessment and upkeep is necessary to extend its life and keep general expenses down. Homeowners must pay more attention to the wear and tear on their roof systems, and make careful decisions about roof system upkeep and replacement.
Buying a new roof system is a crucial investment. Before you invest your money, spend a long time learning how to assess the roofer who may be doing the work.
All roofing contractors are not alike, and NRCA advises you prequalify roofing contractors to finish the job right the very first time. The
following guidelines will assist in your choice:
• Check for a long-term business, telephone number, tax identification number and, where needed, an organisation license.
• Demand seeing copies of the specialist's liability insurance coverage and workers' payment certificates. Make certain the coverage is in effect through the duration of the task. (Note: U.S. employees' compensation laws vary by state. Consult your state's laws
to determine workers' payment insurance coverage requirements.).

• Have the professional discuss his/her task supervision and quality-control procedures. Request the name of the person who will supervise, the number of employees will be required and the estimated time of completion.
• Carefully check out and comprehend any roof warranty offered and look for provisions that would void it. Keep a healthy uncertainty about the most affordable quote. If it sounds too good to be true, it probably is. Remember, cost is only one requirement for picking a roofer. Professionalism and quality workmanship also should weigh heavily on your decision.
Roof system types
Roof systems and materials are typically divided into generic classifications: low slope and steep slope. Low slope roof consists of water impenetrable, or weatherproof, kinds of roof membranes set up on slopes less than or equal to 3:12 (14 degrees). Steep slope roof consists of water-shedding types of roof coverings installed on slopes going beyond 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 principal components:
• Weatherproofing layer or layers-- the weatherproofing element is the most essential aspect since it keeps water from going into a roof assembly.
• Support-- support includes strength, leak resistance and dimensional stability to a membrane
• Appearing-- appearing is the part that secures the weatherproofing and support from sunshine and weather. Some surfacing provide other benefits 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 generally are composed of individual pieces or components installed in shingle fashion. Steep-slope roof assemblies generally consist of three primary parts:.
• Roof deck-- a roof deck is the structural substrate and typically is a wood-based material such as plywood or oriented hair board (OSB).
• Underlayment-- underlayment supplies short-lived defense till a roof covering is set up and supplies a secondary weatherproofing barrier. Often underlayment is described as "felt" or "paper.".
• Roof covering-- the roof covering is the external water shedding product.
