Effects of natural soiling and weathering on cool roof energy savings for dormitory buildings in Chinese cities with hot summers. VIDEO: Click here to watch the Ure-A-Sil System being installed on a modified bitumen roof.ĭuring a follow-up inspection a few days later, the contractor performed an infrared scan of the underlying roof deck. While reflective surfaces mitigate heat pollution. In the end, the Ure-A-Sil System stopped the leaks and the building owner was satisfied with the quality of work. Since this particular project did not require a full-roof system application, it took only a few days to complete. Next, the contractor addressed the “problem areas” of the roof by applying localized sections of our Ure-A-Sil Roof Restoration System. If not addressed quickly, they could lead to a more extensive and costly repair project down the road. Increasing the roofs solar reflectance to 0.74 from 0.44 reduced monthly heat flux through the roof in summer (JuneAugust 2009) by 1722. In cases such as this, compromised flashing details are the most likely spots for roof leaks to occur. Shen and Tan (2009) at Tongji University measured reduction in roof heat flux from application of a reflective roof coating to a naturally ventilated factory in Guangzhou. While the roof was in fairly good condition, the contractor was able to determine that a few isolated portions of the roof membrane-specifically around seams and penetrations-showed significant signs of deterioration, and were in definite need of repair. Retrofitting existing buildings with metal roof panels.

Here is how you can use metal roof panels towards LEED Certification: Solar reflective roof panels reduce heat island ratings. The first step was to identify the source of the leaks. Metal roof panels tend to collect LEED points in a variety of categories, from efficiencies in energy and water to environmental quality and innovation. To determine the extent of the problem, an inspection was conducted by an American WeatherStar Approved Contractor. The property owner did not initially voice concern over the building’s interior climate but did report several roof leaks throughout the building.
