The recent increase in storm frequency - particularly in high-velocity winds - throughout the United States is prompting changes in the roofing industry. Attachment procedures for all roof systems, both steep slope and low slope, are being scrutinized, and code changes are imminent.

Environmental regulations and insurance requirements are playing an increasing role in the types of materials and the methods of application that we will employ in the roofing industry in the near future.

Proper application of sprayed polyurethane foam (SPF) systems is required for the long-term success of the system. Installation is comprised of three stages...

What is the best roof system? This question is posed to members of our industry on a daily basis. Although there are strong opinions from all sectors of the industry on the answer to this question, the answer actually depends on several factors.

The perimeter edge is one of the most vulnerable points of a low-slope roof system. This area is continually susceptible to wind-uplift damage and moisture infiltration.

Not all building leaks are roof leaks. The roof system ties into, adjoins and houses several other building components that, if not properly waterproofed, will contribute to moisture infiltration.

Contrary to popular opinion, the maintenance-free roof system is a misnomer. All types of roofs require a certain level of attention. In fact, from the moment of installation, the roofing system undergoes continuous deterioration. Extreme temperature fluctuations as well as snow, ice, hail and wind prevail upon the roofing surface. In short, the elements are the biggest deterrents to the roof system over its service life. Traffic on the roof and the installation of mechanical and other equipment can also cause physical damage that could lead to roofing failures.

In the past few decades, solar cell technology has evolved from powering calculators to powering emergency road signs, parking lot lights and satellites to providing all of the electrical power for houses.

Over the course of the year, your company probably spends a significant amount of time and resources in providing training in such areas as computer operations, equipment operation and organizational procedures. These are all important elements of a successful company. However, they are all ancillary items, which can increase efficiency but do not add to the bottom line. In most cases, the type of formal training that will benefit your company the most is never provided: training for the applicators.

Most roofing experts would agree that it is a best practice to apply underlayments on steep-slope shingle applications. Underlayments provide benefits to the roof system at the deck and shingle components. These benefits add to the long-term weatherproofing success of the roof system. Another primary reason for their use is that most building codes require the application of underlayments on steep-slope roofs.
