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.

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.

Although simple and utilitarian, the main goal of a roof system is to maintain the watertight integrity of a building and keep its contents dry. The goal of this article is to help building owners, architects and contractors decide which commercial roofing options are right for each unique project. Originally written in by roofing experts R. Dick Fricklas and C. Griffin, this is one of the most comprehensive written guides to commercial flat roofing.
Plexiglas is an all-acrylic material, usually associated with a polymeric, plastic material that is extremely durable, and has excellent weathering properties, and is very resistant to ultraviolet radiation from sunlight and the adverse effects of weathering. Plexiglas is an all-acrylic material, meaning that it is composed entirely of highly durable building blocks called monomers. While this is a clear sheet of the acrylic plastic, most acrylics are blended with other materials to create other easily recognized products such as paint, adhesive or caulk.

The self-adhering, weatherproof, reflective surface not only forms a highly effective barrier to the elements, but also limits solar heating to help keep the temperature of building interiors significantly cooler. Surface reflects heat keeping internal temperatures cooler. Fully pliable and providing a secure seal at edges, corners and over gaps, it is ideal for roof areas that are often difficult to waterproof, including locations where ducts, vents, chimneys, or air conditioning units either protrude through, or are roof mounted.

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.
Capolino, P. Integrity testing is the 'holy grail' of building envelope work. To have an assurance that the portions of a building that are expected to get wet due to weather are in a condition to prevent water transmission to the interior is the goal of every contractor, as well as every owner. As a result an entire industry, that of testing laboratories, has been created.
There are advantages and disadvantages to every type of commercial roofing system. This article will give you an overview of the most widely used types of roofs so that you can make more informed decisions on your commercial roofing types. Sentry Roofing installs and repairs flat roofs, low-slope roofs, metal retrofit roofs and membrane roofs.
