  • Abstract:
    This study discusses the potential areas for productivity improvement in roofing construction. In order to achieve the project objectives, a survey was designed and sent to roofing companies in the midwestern United States. Of the 78 questionnaires sent, 20 were returned. On-site interviews were also arranged to visit the roofing job sites for additional information. The study results indicated that the productivity in roofing construction has been estimated by taking the number of hours worked per day or week and dividing that value into the square footage of work completed. Another finding was that better planning, scheduling, and communication were claimed to have the highest potential for increasing productivity in the roofing industry. The roofing contractors have utilized good employer/employee relationships and camaraderie among crew members within their firms to maintain a high level of productivity. The managers stated that weather and poor communication were the main reasons for lost productivity, whereas field workers pointed out that the roof pitch, height, and age of the roof along with weather were the major causes for lack of productivity in their job-sites. Roofing contractors generally incorporate safety to achieve higher productivity, but they may not consider safety as a high priority in their business. The results of other findings are also discussed in detail.
