Installation of Loose-Laid Inverted Roof System at Fort Wainwright, Alaska
In the summer 1971 the Corps of Engineers replaced the roof on Building 1053 at Ft. Wainwright, Alaska, with a loose-laid inverted roof system. This roof system was selected to permit an evaluation of its performance and potential suitability for general use in Corps construction. The installation of the roof also permitted an analysis of its construction costs and a record of the construction procedures. Costs were identified in terms of costs of the materials used and the number of man-hours required. For the analysis, the job was broken down into four phases: removal of the existing roofing material and preparation of the deck; application of a surface of plywood decking; placement of the butyl membrane and installation of flashings; and placement of the insulation and ballast pavers. The results show that the installation time requirements compare favorably with those of conventional built-up roofs but the butyl membrane and the pavers cause higher material costs. Advantages are in the maintainability of the roof system and in its increased life expectancy. (Author)
