About Hawaii Roofing
Hawaiian Roofing contractors handle jobs like roof repair, roof replacement, maintenance and gutter cleaning. Humidity and moisture are serious problems in Hawaii's moist climate leading to leaks caused by moss buildup or rot.
Typical Climate In Hawaii
Hawaii has a warm tropical climate. Temperatures can average 72 degrees in February to 78 degrees in August. As an island state, Hawaii is cooled by trade winds that average 11.3 mph. Precipitation differs from the windward and leeward sides of the islands, with the windward sides receiving some of the heaviest rainfall in the United States. In dry areas of the island, such as Maui, rainfall averages only 10 inches a year.
Common Roofing Issues In Hawaii
A very common roofing issue in Hawaii is leaking. Due to the tropical and often moist climate, roofing material can deteriorate and then leak. Leaks are most commonly found near drains, protrusions, skylights, vegetation growth, valleys, and flashings. Proper maintenance and inspections can help avoid the development of leaks.
Hawaii requires that general builders and specialty builders have a license. Roofers are required to hold a specialty license. Contractors holding a license must pass an exam on business, law and trade and maintain insurance covering bodily damage liability, workers' compensation and property damage. They must also have four years of full-time supervisory work experience as a journeyman, foreman, supervisor, or contractor within the last 10 years. Their business also must be registered with the Department of Commerce and Consumer Affairs. Roofing contractors should also be bonded.
Energy Efficient Roofs In Hawaii
There are two roofing companies listed as partners of ENERGY STAR. One such company is All Weather Surfaces located in Aiea, Hawaii. They use White Lava Roofing products, which are acrylic and epoxy resin coatings. The Building Industry Association of Hawaii also has a program called BuiltGreen that's an incentive program to encourage environmentally friendly home construction as well as energy-efficient construction. This includes using sustainable roofing materials and R-19 ceiling insulation and/or radiant-barrier under-roof decking.
Unusual Roofs In Hawaii
A new trend in commercial roofing is the concept of a "green roof" or a "living roof." Basically a roof-top garden, "living roofs" use flat roofs of commercial buildings as gardens, which then cool the interior of the building and reduce urban heat island effect. The University of Hawaii at Manoa has been studying the benefits of green roofing since August 2007 as a prototype for future green roofs on campus. Green roofs are believed to mitigate storm water run-off and increase the lives of roofs membranes by protecting them from the harmful elements. Another popular roof design in Hawaii is the butterfly roof. Most commonly seen in the architectural designs of Frank Lloyd Wright, butterfly roofs are two adjacent gables sloping inward. This helps to channel rainwater into a contained place, which is helpful in times of drought. This roofing technique also opens the interior of the house, creating higher ceilings.
