CHOOSING A FLAT ROOF

Building codes are performance and prescriptive requirements for building construction—including roof systems—that are established and enforced by state or local government agencies to ensure public safety, health and welfare in commercial and industrial buildings. Individual state and federal government agencies generally are free to adopt their own codes; however, most adopt model building codes that are developed and maintained by one of the following model code groups:.

ICC has adopted a three-year update cycle for the I-Codes to allow for new construction methods and technologies to be incorporated into the codes. The IBC regulates all types of construction except detached one- and two-family dwellings and townhouses not more than three stories high.

The IBC addresses minimum requirements for preserving the public health, safety and general welfare of the occupants of new and existing buildings or structures. Provisions in the IECC include the minimum thermal insulation requirements for roof systems.

The International Residential Code For One- and Two-Family Dwellings provides regulations for the construction of single-family houses, two-family houses, and buildings consisting of three or more townhouse units up to three stories high. Chapter 8, "Roof-Ceiling Construction," provides attic ventilation requirements.

Virgin Islands use one of several versions of IRC as the technical basis for their adopted building codes. The IECC regulates minimum energy-conservation requirements for new buildings using prescriptive and performance provisions. The IECC addresses energy-conservation requirements for commercial and residential construction.

It provides requirements for all types of building energy uses, including heating and ventilating, air-conditioning, electrical lighting, water heating, and power usage for appliances and building systems.

The IECC also provides minimum requirements for building envelope and building systems insulation, including wall and roof insulation, windows and doors, mechanical system duct insulation and water distribution system insulation. Most energy codes in the U. In some instances, individual states or other jurisdictions modify the IECC to address specific regional or local issues. Click here for additional information regarding energy codes, including state energy code adoptions, roofing-related energy code requirements and NRCA's EnergyWise Roof Calculator Online.

The IGCC contains prescriptive- and performance-based requirements. IGCC is intended to be used by code officials as an enforcement tool to compel the adoption of green and sustainable building design and construction practices significantly beyond the construction market segments addressed by voluntary rating systems. It is designed to allow jurisdictions to tailor the code to address local environmental concerns and advance local agendas. IGCC applies to the construction of high-performance commercial buildings, structures and systems, including existing buildings subject to alterations and additions, utilizing traditional and innovative construction practices.

It also applies to residential occupancies other than low-rise residential buildings that fall under the scope of the International Residential Code. All of the NFPA publications are available online. Standards prescribe levels of acceptability or approved modes to be used in building construction including roof systems as bases of comparison. Test standards prescribe test methods and, sometimes, minimum acceptable results.

Rating standards establish measurement methods to ensure similar products can be compared on the same bases. The following are standards organizations that maintain standards affecting the roofing industry. Also, links are provided to Professional Roofing articles discussing standards' provisions and standards' development and application in the roofing industry.

The following list of ASTM International standard materials specifications applicable to roofing and waterproofing provides a synopsis of each standard.
