The Pros and Cons of Metal Roofing in Central Texas

If you live in Austin, San Antonio, or anywhere across Central Texas, your roof takes a beating — hailstorms in spring, blazing sun in summer, and heavy rains throughout the year. More homeowners are turning to metal roofing as a durable and stylish solution. But is it right for your home?

At JP Exteriors, we install premium systems from Sheffield Metals and McElroy Metal, built to handle the Texas climate. Here’s a breakdown of the pros and cons so you can make an informed decision.

Pros of Metal Roofing

  • Longevity
    Metal roofs can last 40–70+ years with proper installation. That’s two to three times longer than asphalt shingles.

  • Storm Resistance
    Many metal systems carry a Class 4 impact rating (the highest) and strong wind-uplift resistance—key for Hill Country hail and storm events.

  • Energy Efficiency
    With Kynar 500®/PVDF cool roof coatings, standing seam panels reflect solar heat, lowering attic temps and cutting A/C usage by up to 25%.

  • Fire Resistance
    Metal roofing is Class A non-combustible, providing an extra layer of protection in wildfire-prone Central Texas.

  • Rainwater Harvesting Friendly
    Smooth panels shed water and debris easily—ideal for ranches and acreage systems.

  • Lightweight & Structural Friendly
    Weighing less than clay or concrete tile, metal reduces structural load and can often be installed over existing decking.

  • Sustainability
    Metal is recyclable and long-lasting. It pairs well with solar panels for eco-conscious upgrades.

  • Curb Appeal
    Standing seam or R-panel profiles with a wide color palette fit Austin’s modern builds, Hill Country ranch homes, or San Antonio historic districts.

  • Low Maintenance
    Standing seam roofs (hidden fasteners) minimize leak-prone points, cutting down on upkeep.

Cons of Metal Roofing

  • Higher Upfront Cost
    Typically more expensive than asphalt shingles, though the ROI pays off over decades of service life and potential insurance discounts.

  • Oil Canning Risk
    Heat can cause panel waviness. Choosing heavier gauges, striations, and proper installation helps minimize it.

  • Noise Concerns
    Without proper insulation, rain can be louder on metal. High-quality underlayment and attic insulation solve this issue.

  • Expansion & Contraction
    Texas temperature swings mean panels expand/contract. Proper clips and fastener spacing are essential.

  • Corrosion Risks
    Poor installation or mixing metals can cause rust. Choosing Galvalume steel or aluminum helps prevent this.

  • Exposed-Fastener Systems
    While cheaper, R-panels with exposed fasteners require periodic gasket checks and resealing.

What to Ask Your Roofer

Before signing a contract, ask about:

  • Panel type (standing seam vs. R-panel)

  • Metal gauge and substrate (Galvalume recommended)

  • Paint system (Kynar 500®/PVDF for color stability)

  • Underlayment (high-temp rated for Texas heat)

  • Ventilation and flashing details

  • Warranty terms (manufacturer + labor)

At JP Exteriors, we specify Sheffield Metals and McElroy Metal systems with high-temp underlayments and best-practice flashing to maximize lifespan.

Central Texas Considerations

  • Hail & Wind: Choose Class 4 impact-rated panels for storm resilience.

  • UV & Heat: Lighter colors reflect more solar radiation; darker tones create modern contrast.

  • Heavy Rain: Proper panel runs and downspouts ensure drainage in Austin’s sudden storms.

  • Tree Debris: Oak and cedar drops are common—standing seam sheds debris better.

Boosting Curb Appeal & Resale Value

Metal roofs aren’t just functional—they transform the look of a home. Modern standing seam designs are especially popular in Austin infill builds and Hill Country estates. Buyers recognize the value of a roof that won’t need replacing anytime soon.

Final Takeaway

Metal roofing is a smart, long-term investment for homeowners across Austin, San Antonio, and Central Texas. While the upfront cost is higher, the benefits — longevity, storm resistance, energy efficiency, and curb appeal — make it a superior choice.
