A sphalt shingle roofs are one of the most popular roofs in Hawaii. They are moderately priced and generally last between 15 and 30 years before they need to be replaced. Leakmaster Roofing has installed many of these reliable systems for more than 25 years, and continues to do so.

However, there are some notable downsides to these shingles that prompt many Hawaii homeowners to seek alternatives.

First, they can be deadly hot in the summertime. They generally come in darker colors, which attract black mildew growth, making them even darker, hotter and uglier than when they were new. The roof temperatures will often measure about 160 degrees in the summer, which means the homes’ interior is often 8 to 12 degrees hotter than if the roof had a cool roof coating.

Second, high winds will start to blow off the shingles, especially after they have aged over eight years or so and have gotten brittle. This happens because the sun’s UV rays have dried out the essential oils in the shingles and make them vulnerable to our trade winds. Unfortunately, they tend to fail at the worst possible time, causing expensive interior damage.


The attraction of coated Cool Roofs is that all the shingle tabs are glued in place by the thick, waterproof elastomeric coatings. There is no place for wind to lift up a shingle and blow it off. As soon as the roof is coated, the sun’s UV rays are blocked from the shingle. No further degradation from the sun can occur due to “thermal shock” as well. Your roof temperature is lowered 60 to 70 degrees, making living below it cool and comfortable. A/C costs are lowered, on average, about 22 percent. Over time, it pays for itself. You never have to pay to tear off your old roof and haul it to the dump, you simply re-coat when needed with just a fraction of the original coating.

It is the most economical solution available. Whether you opt for a simple “Reflectivity Coat” or the full-blown waterproof, windproof system you will be saving money.

The top coat can either be a silicone-based coating, with material warranties up to 50 years, or an acrylic-based coating such as NXT Cool Coat, which comes in 36 designer colors and brilliant white.
