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.
To a large extent, successful roof applications are completed by skilled mechanics that conduct systematic tasks in a repetitive manner. Repetition increases the skill level, which in turn increases productivity. This is a constant in an industry that (largely) derives profit from production. Most companies train their mechanics to be productive workers. There is one sector of the industry that requires a different mindset: the repair sector. Skills required here include patience, persistence and analytical thought.
A properly implemented roof management and maintenance program could effectively extend the service life of a roof system and eliminate some of the complexities associated with this critical building component. Detailing the procedures and benefits of a well-executed roof management program can help contractors convince building owners of the merits of instituting such a program, to the advantage of both parties.
The roofing industry is now at a point where we should collectively define a uniform standard for the determination of moisture content in roof systems. It is time to move past the days of the "educated toe," i.e., subjective claims of how the system felt as it was walked across. A standard would benefit all sectors of the industry preventing frivolous lawsuits and unsubstantiated claims driven by the pursuit of profit.
As we enter the 21st century, there are significant issues facing the roofing industry, such as labor shortages, environmental concerns, and the depletion of natural resources. Time-tested systems are being replaced by newer systems and materials are being updated to meet the current environmental conditions. In this era of rapid change, there are many positive developments to point to in the roofing industry.
Environmental issues continue to be at the forefront of the roofing industry. These issues and regulations are having an impact on the design and application of roof systems and materials that we will be using well into the 21st century. Groups such as the U.S. Green Building Council, the Department of Energy, and the Environmental Protection Agency are forming regulations that will eventually become part of the building codes. Roofing contractors should be aware of these regulations and have an understanding of them and of the impact that they will have on the industry.
