Metal Roofing in Hawaii, Your Best Choice

Protect your investment and learn all the benefits of metal roofing here. 


Your home is one of the most significant investments you’ll make in your lifetime. Deciding what kind of roofing material best protects your investment is an overwhelming task.

However, with improvements in metal roofing over the past decade has made your decision easier. Metal has been increasingly recognized as a viable construction and reroofing option in Hawaii. Here are several important reasons for the acceleration in popularity of metal roofing for new construction and re-roofing:

More Energy Efficient

Metal roofs can reduce your energy costs by as much as 25-percent compared to other roofing materials! Metal roofing panels reflect solar radiation far more efficiently than traditional materials, which absorb and retain more heat.

For example, our HPM Custom Metal Roofing is coated with Durapon 70 PVDF Fluorocarbon. Durapon 70 is made with cool roof pigments that deflect UV rays to lessen the absorption of heat, keep your home naturally cooler so you can run your A/C less and save dollars off your electric bill.

Durability and Longevity

Asphalt can require reroofing every 12 to 20 years. That’s because the granule coating over the asphalt begins to fall off as soon as it rains and continues with each rainfall crating a non-aesthetically pleasing roof. However, a metal roof with a Durapon 70 paint finish stands up much better to UV rays and can last up to 35 years without excessive fading!


Most metal roofs have a minimum 25-percent recycled content, making them a green alternative to traditional products. When removed, metal roofing is 100% recyclable!

More Colors, More Options

Metal roofing is also available in many durable colors to match any residential or commercial design. View available HPM Custom Metal Roofing Energy Star rated colors >>

Protection from Lightning, Fire, and Extreme Weather

A metal roof does not increase the likelihood of a lightning strike. If your roof were hit by lightning, your metal roof would disperse the energy safely throughout your home. Since metal roofing isn’t combustible or flammable, it’s a low risk and desirable roofing option where severe weather is concerned, especially for lightning.

You’ll be surprised, but metal roofing can also withstand abuse from extreme weather including high winds!
Have you seen the metal roofs that fly off on the news that still have the framing attached? It’s not the roofing that failed, it’s the framing! Living in Hawai‘i and knowing our history of hurricanes, let’s just say, it’s better to be safe than sorry!

Less Noise

If installed with a solid sheathing underneath, metal roofs will silence noise from rain and wind, providing better noise insulation than traditional materials.

Corrosion Resistant

Today, metal roofing is coated with an additional metallic layer made of a mixture of zinc and aluminum, which will slow down the oxidation process that leads to rust. This offers 2-4 times the corrosion resistance of standard galvanized material. The use of Duracoat’s Edge Seal will help to aid in this process. We also stock aluminum for even greater corrosion resistance. Expected lifespan of metal roofing in Hawai‘i could be from 20-40 years with proper maintenance.
