When it comes time to replace your roof, the biggest question isn't just who will do the work—it's what material will protect your home best. Here's how metal roofing and asphalt shingles really stack up in a Texas climate.
If you're planning a roof replacement, you've probably seen ads for metal roofing online. Some claim it's the 'best choice' for Texas. Others stick with traditional asphalt shingles because that's what most homes have. The truth is that both materials can perform well in our climate—but they serve different priorities and budgets. Here's a practical comparison to help you decide.
Cost: the first major difference
This is often the deciding factor. Architectural asphalt shingles typically cost $8,000–$15,000 for a full roof replacement on a standard residential home in the San Antonio area. Metal roofing for the same home runs $15,000–$30,000 or more, depending on the profile and finish. For budget-conscious homeowners, that difference is significant—and it matters.
However, metal roofing often qualifies for tax credits, insurance discounts (especially in hail-prone areas), and energy-efficiency rebates that can narrow the gap. Ask about these before making your decision.
Lifespan and durability
Asphalt shingles: 15–25 years under normal conditions, often less in harsh Texas heat. Premium architectural shingles last longer than 3-tab versions.
Metal roofing: 40–70 years depending on material (aluminum vs. steel) and maintenance. Standing seam systems often last 50+ years.
If you plan to stay in your home long-term, metal roofing means one less major expense in your future. If you'll move in 10–15 years, asphalt shingles might be the more practical choice.
Performance in Texas weather
Both materials handle Texas weather well when properly installed, but they have different strengths:
Hail: Metal roofing (especially standing seam) is more resistant to hail damage than asphalt shingles. In hail-prone areas like Boerne and Bandera, metal often qualifies for better insurance rates.
Wind: Both materials can be installed to handle high winds when properly fastened and sealed. Metal has a slight advantage at extreme wind speeds.
Heat: Metal reflects solar heat, keeping your attic cooler and reducing cooling costs. Asphalt absorbs heat, which can age the material faster.
UV damage: Asphalt gradually deteriorates from UV exposure and heat cycling. Metal with a quality finish resists UV damage much better.
Maintenance differences
Asphalt shingles require more ongoing maintenance: regular inspections for curling or missing shingles, resealing of flashing, and often repairs of individual damaged sections. Metal roofing requires less hands-on maintenance, though fasteners should be checked periodically and the finish inspected every few years.
Aesthetics and curb appeal
Asphalt shingles come in many colors and architectural styles that blend seamlessly with traditional Texas homes. Modern metal roofing also comes in diverse styles and colors, though the look is distinctly different—some homeowners love the sleek, modern aesthetic; others prefer the traditional shingle appearance. Check your HOA rules if you live in a gated community or planned neighborhood.
Energy efficiency and cooling costs
Metal roofing's reflective properties can reduce your summer cooling costs by 10–20%, depending on color and how much direct sun your roof receives. This adds up over 30+ years. Asphalt shingles, especially dark colors, absorb solar heat and work against your air conditioning.
Which should you choose?
Choose asphalt if: You're on a budget, you plan to move within 15 years, you prefer a traditional look, and your home is in a lower-hail-risk area.
Choose metal if: You plan to stay long-term, you want maximum hail/wind protection, you value energy efficiency, you live in a hail-prone area (and want insurance savings), and you're okay with a higher upfront investment.
The honest truth is that a properly installed asphalt roof can protect your home effectively for 20+ years. Metal roofing offers more longevity and lower maintenance but at a higher cost. Both are solid choices—it just depends on your priorities and timeline. At Relentless Roofing Endeavors, we install both and can walk you through the tradeoffs specific to your home and situation.
