Although basic and utilitarian, the main goal of a roof system is to preserve the leak-proof stability of a structure and keep its contents dry. Today's range of flat or low slope industrial roofing options (roofing pitches varying from:12 to 3:12) is no longer easy and has grown significantly in the last 50 years. CertainTeed roofing.
You might ask, "Why have a flat roofing system on a structure?" That's a great question! Flat roofing systems are nothing new, nor are a few of the proven products that cover these often-expansive roofing systems such as those discovered on factories, storage facilities, huge and little box shops, apartment or condo structures, big public structures and schools/universities.
Let's explore the following topics as they relate to the primary low slope roofing systems: Product functions, advantages and differences Accessory options General maintenance and service warranties After a current evaluation of the Manual of Low-Slope Roofing Systems * (hereafter referred to as the Handbook), this handbook will be referenced throughout this article.
( Cock) Fricklas and C - best roofing.W. Griffin, this is one of the most extensive composed guides to business flat roof. The (NRCA) provides a robust site and resources geared for contractors about everything roof associated. Their easy-to-navigate site provides an extensive introduction of products, applications, courses and other resources for contractors and structure professionals.
The 2015-2016 NRCA Market Study http://www. nrca.net/2016-market-survey programs that roof system types throughout the U.S. continue to show the current patterns in low slope business roof applications. The study results program TPO as the low-slope market leader, amassing a 40 percent share of the new building and construction market and 30 percent of the reroofing market.
In third location is Mod Bit at 12. 4 percent of the new building market and 14 percent of the reroofing market. Market share for these and other system solutions follow by portion in the chart below: From here, we'll take a look at these low slope roofing system choices in the chart, from those with the smallest market share to the biggest.
Liquid applied membrane systems need extensive preparation of the substrate, which need to be dry and dust-free with patched cracks. While liquid applied coverings are extremely elastic, self-flashing and quickly applied to contoured surface areas, they have low permeability and require consistent density. The NRCA provides an online course Style Essentials for Roofing System Performance: Liquid-applied Roofing System Membranes for a thorough appearance at liquid-applied roofing system membrane choices.

However, the investment for a metal roof option likely will be much higher upfront than other flat roofing options. The Metal Construction Association (MCA) uses resources for those interested in discovering more about making use of metal as a low slope roof solution.

These complimentary resources include bulletins, white documents, handbooks and reports. Low slope structural metal roof is commonly understood as standing seam roof and consists of interlocking panels that run vertically along the roofing system surface.
Some metal roofing utilized on low slope applications requires machine seaming throughout setup to guarantee a water tight seal. A seaming apparatus is merely rolled along the panels to crimp the panel joints together. A standing seam style assures adequate draining from rain and snow, efficiently getting rid of ponding, leakages and related issues.
This may result in a longer life period and low yearly operating expenses. In retrofit projects, a sub-framing system is connected to the existing flat roofing system surface to supply a minimum:12 roofing pitch. Choices for the remediation of a metal roof surface include acrylic coverings made from polymers that treat to form a resilient, continuous elastomeric membrane over the surface area of the metal roofing and can be contributed to metal roofing systems to resolve your building's specific requirements around waterproofing, rust and UV protection.
Acrylic coverings are water-based, non-flammable and release no harmful fumes. These systems can stand up to the most common kinds of roofing risks, consisting of ultraviolet light, temperature extremes, mildew, normal foot traffic and building movement. While not on the list in regards to market share, another roof need to be discussed the vegetative or "green" roofing system.
