Description:
An experimental study was conducted to determine an appropriate adjustment period using the psychophysical approach for evaluating acceptable work limits for a task involving sloped walking/working surface. A workstation was designed and constructed to simulate a sloped residential roof. Twelve healthy males from a university population served as subjects. The subjects were provided training until the experimenter was confident in their ability to perform the simulated roof-shingling task, while comparing to the experienced roofers’ performance. Results indicated that 198 shingles/h is an acceptable roof shingling frequency for a workday. Time period had significant effect on psychophysical, postural sway, and selected physiological responses. Appropriate adjustment period using the psychophysical approach for evaluating acceptable work limits for tasks involving sloped surface was determined to be 2h. Postural sway and physiological variables support these findings. The results from this study could aid in setting safe work limits in roofing construction for males. This study may prove to be useful for practical applications for the reduction of the risk of occupational injuries and fatalities, while improving productivity and safety in the roofing industry. Relevance to industry: Results from this study could aid in setting acceptable work limits for roof shingling operations. Ergonomic intervention may decrease the risks of falls from roof thus reducing workers compensation costs and lost productivity of the worker. .

The book covers all roofing systems. Although it has specifications and shows how roofs are applied it primarily deals with problems that exist in all the roof systems that are created as a result of poor workmanship or deception on the part of the roofing contractor and the builder. It also deals with why roofing products fail and why certain specifications are failures. It shows the problems in photo illustrations as well as how to remedy those problems. The section on construction defect litigation deals primarily with how lawyers take advantage of homeowners in construction lawsuits. It has several hundred photo illustrations of roofing issues. Additionally there are several hundred questions and answers a homeowner or consumer would ask of an expert. The case studies, on site experiences and details all combine to give the reader a comprehensive view of the roofing industry and concerns.
Customer Review: REVIEW BY A ROOFING WHOLESALER
Mr. Osterman’s knowlege of the roofing industry allows him to really tell it like it is. It’s no holds barred information that everyone who owns a roof, designs a roof, or installs a roof should have access to.

The book is quite lengthy but it’s reference value is immense. It covers basicly every aspect of roofing and the roofing industry. It seems to emphasize the flaws in the industry more so than the professionalism that exists side by side with the “Tin Man” perception many hold. This skepticism is really what make the book unique.
Customer Review: A veritable encyclopedia on your roof
This book is titled “Things You Should Know About Your Roof, Your Roofing Contractor and the Roofing Industry,” but it really should be titled “EVERYTHING You Should Know……”

Charles Osterman, who has more than 50 years of experience in the roofing business, takes the reader through all the common problems with all types of roofs, and he does it with simple, straightforward language. The book is geared to the average homeowner, and is chock full of photographs and diagrams of common roofing problems. Nonetheless, my guess is that an expert would probably gain some insight from reading this lengthy (605 pages) book. .
