New technology means roofs last even longer

By Hawaii Renovation Posted in: ExteriorRoofing

Roofing products are constantly evolving as traditional materials, such as asphalt, are improved by using cutting edge science to create fantastic new hybrids. LeakMaster Roofing installs all major systems and is constantly on the lookout for the latest technology that address the problems of the past.

Most new benefits fall into one of two categories: they either last longer than previous products or they make your home cooler — preferably both. A cool roof is a happy roof because it doesn’t degrade as quickly from “thermal shock” or UV damage.

Energy Star-rated asphalt shingles

Most of the roofs in your neighborhood are probably asphalt shingles (also called “comp shingles”). They are still the most popular sloped roofs in Hawaii and there are many good reasons for this. They are moderately priced and perform very reliably when properly installed. If you have to walk on them, they are more forgiving than many other roof types. In short, they are a safe bet.

However, traditional comp shingles get very hot with surface temperatures often exceeding 170 degrees in the Hawaiian summer sun. This can make your interior home temps about 5 to 12 degrees hotter than they need to be. The latest Landmark Solaris shingles from CertainTeed are Energy Star rated. LeakMaster

Roofing is finding a definite move towards cool roofs in general, and the Solaris is a solid performer. This type of roof also has an increased mildew resistance warranty of 15 years and a wind warranty up to 130 mph when properly installed. These are both huge features in Hawaii.

Cool roof coatings: acrylic vs. silicone

Leakmaster Roofing has been a leader in innovative roof coatings since 1990. The company has pushed for installing “full fabric reinforced systems” at 4 to 5 gallons per 100 SF, instead of the more common unreinforced 2-3 gallon systems that inevitably fail. It also pioneered roof coatings, such as the Cool Roof Store Ceramic, that keep you cool in the summer. Leakmaster Roofing has been met with an enthusiastic reception here in Hawaii.

Lately, there has been a big surge in silicone coatings due to their ability to withstand ponding water indefinitely. The newest silicones are now 95 percent solids vs. 69 percent, so you end up with a thicker membrane — 40 mils vs. 22 mils — when the roof is finished. Because silicone is considered “non-sacrificial,” meaning it won’t chalk off over time, it’s lifespan is very long. GacoRoof and Apoc warrant their coatings for an impressive 50 years. When applied properly by an approved Installer, labor and warranties of up to 20 years are available on qualifying jobs.
