An Alpha roof is a type of Spray Polyurethane Foam (SPF) roofing system that has been documented to be one of the highest performing roofs in the industry. Despite the high level of performance of the Alpha SPF roofs, owners still try to protect themselves by purchasing warranties. When the Dallas Independent School District (DISD) did not receive enough funding to purchase the Alpha roofs for their school buildings, general contractors started shopping the Alpha contractors. The demand for Alpha roofs during DISD bond programs exceeded the supply of Alpha vendors. DISD lowered the requirements and the contractors and manufacturers delivered lower quality roofs. DISD still required the performance of the Alpha roofing system, even though they bought lower performing systems without the quality control requirements of the higher performing Alpha roofs. DISD was not happy with the lower performance on some of the inexpensive roofs. This paper describes a case study that proposes that high roof performance is a result of expert contractors proving their past performance, detailed preplanning, manufacturers doing quality control, contractors tracking their time and cost deviations and independent third party inspections. The expert Alpha contractor completed the project with the best dimensional stability metrics (dimensional stability is a metric of long lasting roofs). The roof installation was completed in 20 days and saved DISD over 20% of the cost of the roof, despite an increase in the scope of work. It was the first DISD project that had no punch-list items after the final walkthrough. DISD was extremely satisfied with the roof and the Alpha program demonstrated its effectiveness in the installation of roofs.

“…The Alpha SPF roof system has the following attributes (Kashiwagi, 2016;Kashiwagi, 2015 SPF roofing has an R-value of R6 per inch and is used by the owners of the building as a recovery system over existing roofs including built-up roof (BUR), modified bitumen, concrete, wood, asphalt shingles, clay tile, and metal (Knowles, 2005). The advantage of the Alpha SPF roof system is that it does not require the removal of the existing modified or BUR system saving owners as much as $6/SF (50% less than the traditional BUR system) in removal costs and costs of a new modified or BUR system.…”

“…A properly installed Alpha roof system has been documented to resist up to 4 inch diameter simulated hail stones (four inch diameter steel ball dropped from more than 17-3/4 feet height). (Kashiwagi, 2015, Kashiwagi andSavicky, 2003) The Dallas Independent School District (DISD) has been using the Alpha roofing system since 2002, when they ran a Best Value test to compete the modified BUR system with the Alpha system. The results showed that the Alpha SPF roof systems were installed with high performance with proven longevity and durability.…”

The Cost Effectiveness of Alpha SPF Roofs: Casa View Elementary School Roofing Case Study

The performance of the Alpha Sprayed Polyurethane Foam (SPF) roofing system is perceived as not an economical option when compared to a 20-year modified roofing system. The Dallas Independent School District (DISD) is replacing the existing Alpha SPF roof systems with new roof systems rather than recoating the existing systems at a cost that is 100% more than the recoating costs. The DISD is in a heavy hail area, and the proven hail resistance of the Alpha SPF roof system is an additional benefit for DISD who is self-insured. The Casa View Elementary School roof system was installed with a Neogard Permathane roof system in 1987. This roof was hail tested with ten drops from 17 feet 9 inches of 1-3/4-inch steel ball (9 out of 10 passed) and three drops from 17 feet 9 inches with a 3-inch diameter steel ball (1 out of 3 passed). The analysis of the passing and failing core samples show that the thickness of the top and base Alpha SPF coating is one of the major differences in a roof passing or failing the FM-SH hail test. The current potential cost savings of purchasing a 61,000 square feet Alpha SPF roof versus modified bitumen roof is approximately $610,000 for DISD. The past hail tests on Alpha SPF roof systems show high customer satisfaction (9.8 out of 10) and an over 40-year service life after a $6.00/SF recoat.

Development of the Use of Performance Information

This paper documents the history of the development of performance information [1982-2020], for the delivery of services. It identifies traditional industries as client controlled. In the past, clients utilized a structure of technical professionals who had education, certifications, and experience. Professionals set both policy and structure for their professionalism. The traditional industry does not differentiate between the values of vendors, professionals and stakeholders. This paper identifies that professionals are resistant to using performance information which differentiates. The initial proposal to successfully implement information management was to use automation. However, the industry resisted the automation and the research identified that simplicity and transparency was the only solution. This paper identifies that the Performance Based Studies Research Group’s (PBSRG) success in performance information development was due to a unique design and methodology to research performance information as a disruptive technology. A new methodology called the Information Measurement Theory (IMT) was designed to redefine risk, expertise and information. The major source of validation of the new concepts was joint academic and industry research tests. Three major research tests confirmed that the client creates over 90% of all risk. PBSRG worked with a manufacturing company to design a high-performance roofing program which ended after 16 years due to it being based on client centric concepts. An expert contractor took the lessons learned and maximized the use of performance information with a vendor centric approach.
