Although easy and utilitarian, the main goal of a roof system is to preserve the watertight stability of a structure and keep its contents dry. Today's range of flat or low slope industrial roof alternatives (roof pitches ranging from:12 to 3:12) is no longer easy and has grown considerably in the last 50 years. EPDM roofing.
You may ask, "Why have a flat roofing on a building?" That's a terrific question! Flat roofs are absolutely nothing new, nor are some of the proven materials that cover these often-expansive roofing systems such as those discovered on factories, warehouses, huge and little box stores, apartment or condo structures, large public structures and schools/universities.
Let's check out the following subjects as they relate to the main low slope roof: Product functions, advantages and differences Attachment options General maintenance and warranties After a current evaluation of the Handbook of Low-Slope Roof Systems * (hereafter referred to as the Handbook), this handbook will be referenced throughout this post.
( Dick) Fricklas and C - architectural roof shingles.W. Griffin, this is among the most comprehensive written guides to business flat roofing. The (NRCA) offers a robust site and resources geared for contractors about everything roof related.

In 3rd 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 percentage in the chart below: From here, we'll examine these low slope roof system options in the chart, from those with the tiniest market share to the greatest.
Liquid used membrane systems need strenuous preparation of the substrate, which should be dry and dust-free with patched cracks. While liquid used finishes are extremely flexible, self-flashing and quickly used to contoured surfaces, they have low permeability and need uniform density. The NRCA offers an online course Style Essentials for Roof Efficiency: Liquid-applied Roof Membranes for an in-depth take a look at liquid-applied roof membrane choices.

Nevertheless, the investment for a metal roof solution likely will be much higher in advance than other flat roof solutions. The Metal Building And Construction Association (MCA) provides resources for those interested in discovering more about the use of metal as a low slope roofing service.

These free resources include bulletins, white documents, handbooks and reports. Low slope structural metal roofing is commonly called standing seam roofing and includes interlocking panels that run vertically along the roofing system surface.
Some metal roofing utilized on low slope applications needs maker seaming throughout setup to guarantee a watertight seal. A seaming apparatus is merely rolled along the panels to crimp the panel seams together. A standing seam style assures adequate draining from rain and snow, successfully eliminating ponding, leaks and associated issues.
This may result in a longer life expectancy and low annual operating expenses. In retrofit jobs, a sub-framing system is connected to the existing flat roofing system surface area to supply a minimum:12 roofing system pitch.
