Some of the longest lasting roofs.

Metal roofs are a popular roof option here in Hawaii, because they are long lasting, lightweight and easy to install.


Unfortunately, their downfall is that they require maintenance and can be costly to repair.


Luckily, there is a simple solution you can do yourself! Never re-roof, simply coat your roof with high performance, waterproof and reflective coatings.


Metal roofs can be coated in both a silicone or acrylic based coating depending on your needs. These coatings are highly reflective and will lower your home’s interior temperatures. NXT Cool Coat is an acrylic that can be tinted in over 36 color options.


Metal roofs are one of the best roofs for Hawaii. Most metal roofs can be easily repaired and made to last the lifetime of the building.

If you want a new roof we recommend local manufacturer HPM who has serviced Hawaii for decades.  We also use Kloeckner Metal (formerly MacSteel) for both standing seam metal roofs as well as standard corrugation.

LeakMaster's Opinion

The one thing you have to watch out for on older roofs is rust.  Most rust can be stopped with NXT Metal Primer if its not too far gone. These can also be topcoated with a silicone, which come in a white, grey or tan color.  If you desire more custom colors for design reasons, we use NXT Cool Coat which will reflect UV sun rays and keep the interior of the building cool, even with dark colors.

Pros & Cons


  • Standing seam metal requires very little maintenance and looks beautiful

  • Their Kynar paint finishes are very durable


  • Standing seam roofs cost more than regular corrugation, which has exposed fasteners which can rust

  • Corrugated roofing, if not coated, will rust over time.
