Metal Roofing vs. Asphalt Shingle Roofing in Tropical Climates

Ever wonder why there are so many different types of roofs in Hawaii, but there seems to be a dominance of metal roofs?  When it comes to roofing in tropical climates like Hawaii, homeowners and contractors often weigh the pros and cons of metal roofing versus asphalt shingles. Both options have their advantages, but in a place where sun, salt air, heavy rains, and high winds are part of daily life, choosing the right roofing material is crucial.

The Pros and Cons of Metal Roofing
Pros of Metal Roofing
✅ Durability & Longevity – Metal roofs can last 40–70 years, significantly longer than asphalt shingles, which typically last 15–30 years (sometimes much shorter due to the climate). Their resistance to rot, insects, and fire makes them ideal for tropical environments.  See our blog post about Copper and Aluminum roofs which can last hundreds of years!
✅ Weather Resistance – In hurricane-prone regions like Hawaii, metal roofing stands out for its superior wind resistance. Many metal roofs are rated for winds of 140 mph or more, making them a reliable choice during storms.  See our blog post about extreme weather and how metal roofs hold up.
✅ Energy Efficiency – Metal reflects sunlight rather than absorbing it, reducing heat buildup in homes and lowering cooling costs—a major advantage in a warm climate. Some metal roofs are even coated with reflective materials to enhance this effect.
✅ Sustainability – Made from recyclable materials, metal roofing is an eco-friendly choice. Unlike asphalt shingles, which contribute significantly to landfill waste, metal roofs can be recycled at the end of their lifespan.

Cons of Metal Roofing
❌ Higher Initial Cost – Metal roofing has a higher upfront cost than asphalt shingles. However, its longevity and energy savings often make up for the initial investment.
❌ Noise Factor – Without proper insulation, metal roofs can be noisier during heavy rain, which is common in tropical regions. However, modern installation techniques minimize this issue.
❌ Potential for Dents – While metal roofing is highly durable, softer metals like aluminum can dent from heavy debris or hail. However, many high-quality metal roofs are designed to withstand impacts.

The Pros and Cons of Asphalt Shingle Roofing
Pros of Asphalt Shingle Roofing
✅ Lower Upfront Cost – Asphalt shingles are generally more affordable than metal roofing, making them an attractive option for budget-conscious homeowners.
✅ Easier Installation & Repairs – Shingles are simpler to install and repair compared to metal roofing, which requires more expertise.
✅ Variety of Styles & Colors – Asphalt shingles come in a range of styles, offering more aesthetic flexibility for homeowners.

Cons of Asphalt Shingle Roofing
❌ Shorter Lifespan – In Hawaii’s humid and salt-laden environment, asphalt shingles tend to deteriorate more quickly, requiring replacement more often.  You may have to replace a shingle roof 3 times before replacing a metal roof.
❌ Lower Wind & Weather Resistance – Asphalt shingles are more vulnerable to wind uplift, rain penetration, and mold/mildew growth in tropical conditions. Strong storms can cause shingles to tear or blow off entirely.
❌ Heat Absorption –Shingles absorb heat, which can make homes warmer and lead to higher cooling costs in hot climates.

Why Metal Roofing is the Preferred Choice in Hawaii
While asphalt shingles remain popular nationwide, metal roofing has gained significant traction in Hawaii due to its superior weather resistance, longevity, and energy efficiency. The island environment presents unique challenges—constant UV exposure, salt-laden air that accelerates material degradation, and the potential for strong winds during hurricane season. Metal roofs stand up to these challenges better than asphalt shingles, making them a more reliable long-term investment.
Additionally, Hawaii’s focus on sustainability aligns well with metal roofing’s recyclable materials and energy-saving benefits. Homeowners looking to reduce their environmental impact and utility costs often find metal roofing to be the ideal solution.

​Conclusion
Both metal and asphalt shingle roofing have their pros and cons, but in tropical climates like Hawaii, metal roofing emerges as the preferred choice for durability, energy efficiency, and weather resistance. While the initial cost may be higher, the long-term benefits make metal roofing a smart investment for homeowners looking to protect their homes from the elements.
