Better Performing Dryable Insulation System for Low-Slope Roofs

Abstract

Low-slope roofs are widely used but they are often vulnerable to water damage. As removal of water is difficult and expensive, low-slope roofs often have short service life and poor cost-performance ratio. To improve the durability of low-slope roofs, a dryable-on-demand roofing system has been proposed. The design, which includes a mechanism for moisture detection, was evaluated by means of numerical modeling and laboratory measurements. Compared to traditional low-slope roofs, the suggested design offers several advantages including better cost-effectiveness, lower replacement costs, and lower use of resources. The paper shows that building envelope components that are prepared for repair and maintenance may be cost-effective.

Structural and Durability Analysis of a Novel Re-Roofing Concept

“…The concerns relating to the durability of lowslope roof assemblies and management of replacement and/or repairs has been studied greatly (Rudbeck 2001;Lounis, Vanier 2000;Xing, Taylor 2011;Marques et al 2011;Choi et al 2012;Dong et al 2005;Costello 2011). Hygrothermal analysis of new roofing strategies is essential.…”
