<\/a>Although standing-seam roofs are designed to be waterproof, if there is a leak it is vital to have a secondary water barrier to minimize any consequential damage to the interior of the building and allow ample time for repairs to be made.<\/p><\/div>Temperatures in Hawaii seldom get too high or too low, so roofing installers don\u2019t have to deal with temperature extremes. \u201cThe self-adhering underlayment handles extremely well in the 70 to 80 F temperature range, which is typical around here,\u201d Foust says.<\/p>\n
Climate Zones<\/h3>\n The roof on the Safeway store is a hydrodynamic design, which means gravity removes the water from the roof, so it is not susceptible to ponding. Honolulu receives an average of 22 inches of rain per year. Thus, the secondary water barrier capability and the long-exposure limits were important factors in selecting the self-adhering underlayment for this project.<\/p>\n
The Hawaiian Islands are noteworthy for their many climate zones. Although moderate temperatures and moderate rainfall are typical in Honolulu, the climate zones around the big island of Hawaii vary from tropical to subarctic. There is snow in the mountains in the winter and certain micro-climates can experience more than 100 inches of rain per year. Because of the varying climate zones, metal roofing and high-performance underlayments have become quite popular. In fact, metal roofing composes about 25 percent of the commercial buildings and an ever-growing percentage of the residential construction in the Aloha State.<\/p>\n
\u201cWe receive consistently positive feedback from our customers and repeat sales due to ease of installation, walkability and cooler surface temperature,\u201d Foust concludes.<\/p>\n
