Asphalt Shingle Roofing vs. Metal Roofing: What’s Best for Your East Tennessee Home?

asphalt vs metal roofing

When it’s time to replace your roof, one of the biggest decisions you’ll face is choosing the right material. In East Tennessee—where weather patterns can swing from hot, humid summers to chilly, wet winters—your roof needs to be durable, energy-efficient, and visually appealing. Two of the most popular roofing options for homeowners in Knoxville and the surrounding areas are asphalt shingles and metal roofing. Each comes with its own set of advantages depending on your home’s style, budget, and long-term goals. Let’s break it down.

How Long Does a Roof Last? 

Asphalt Shingles:

Modern asphalt shingles, especially premium lines like GAF Timberline HDZ, are built to last. GAF Timberline HDZ shingles are engineered for strength and wind resistance—crucial in East Tennessee, where severe storms and high winds can occur. With proper installation, these shingles can last 20–30 years, offering solid protection without breaking the bank.

Metal Roofing:

Metal roofs are known for their exceptional durability, with a lifespan of 40–70 years on average. They’re fire-resistant, hold up well in heavy rains, and can shed snow more easily—a nice perk if you live in higher elevations around the Smokies. However, in extreme temperature swings, expansion and contraction may create some noise or stress on the roof if not installed properly.

Verdict:

Both are durable, but metal has the edge for longevity. That said, high-quality shingles like GAF Timberline HDZ provide excellent protection in many different weather conditions common to East Tennessee.

Which Roof Styles Look Better? 

Asphalt Shingles:

One of the biggest advantages of asphalt shingles is versatility. Asphalt shingles come in a wide range of colors and textures, including options that mimic wood shake or even slate. This means you can easily match your home’s aesthetic—whether it’s a charming craftsman in Bearden or a classic ranch in Farragut, you can guarantee there is an asphalt shingle option that will enhance your home’s appearance.

Metal Roofing:

Metal roofs have a modern, sleek appeal and come in various profiles and colors—from standing seam panels to metal shingles. They’re popular for cabins, modern farmhouses, and contemporary builds, especially in rural or mountainous areas.

Verdict:

Asphalt shingles offer broader styling options for traditional homes. Metal roofing shines when you’re going for a bold or rustic-modern look.

What’s More Affordable: Asphalt Shingles or Metal Roofing? 

Asphalt Shingles:

Asphalt shingles are generally more budget-friendly. If installed properly, a high-quality asphalt shingle roof may never require repairs during its lifespan. You can expect to replace your asphalt shingle roof once or twice within a 50 year period. Minor repairs are occasionally needed, and are generally caused by storm damage, ice dams, poor attic ventilation, flashing failures, or even tree limb damage. Minor repairs can run anywhere between  $1,000-$2,000 on average. GAF Timberline HDZ shingles in particular, offer an excellent cost-to-performance ratio—making them ideal for homeowners who want quality without overspending. 

Metal Roofing:

Metal roofing costs significantly more upfront—often two to three times the cost of asphalt shingles. This can be offset over time by fewer replacements and slightly lower energy bills due to better heat reflection. Required repairs are typically caused by expansion or contraction of the materials, sealant degradation, or even hail damage. Repairs often require entire pieces of metal to be replaced, which can have a higher cost. Metal roofs can last the entire lifetime of a home, sometimes with minimal intervention. 

Verdict:

If you’re looking to stay within budget or plan to sell within the next 15–20 years, asphalt shingles (especially a trusted brand like GAF) are a smart investment. If you are in your forever home or style is a priority in your modern home, metal may be worth the upfront cost.

Best Roofing Option for Your Home in East Tennessee

Asphalt shingles are a great option for traditional neighborhoods, HOAs, and mid-range homes throughout Knoxville, Maryville, & Oak Ridge. If your goal is to refresh your home’s look in the most affordable way, while still adding long-term value, asphalt shingles may be your best option.

Metal roofs are often best in rural homes, cabins, or for homeowners prioritizing long-term investment and energy efficiency. Metal roofs tend to be most popular in more rural places like Lenoir City or Loudon (links) and even higher elevation properties. 

How to Decide What’s Right for Your Home?

Ask yourself a few key questions:

  • How long do you plan to stay in your home?
  • What’s your budget for the project?
  • What style fits your home best?
  • Are you dealing with any specific challenges like tree coverage, snow load, or high winds?

At the end of the day, you can’t go wrong with a high-quality shingle like GAF Timberline HDZ, which offers a solid mix of performance, beauty, and value for East Tennessee homes. But if longevity and style are your top priorities, and you’re ready for a higher upfront investment, a metal roof could be the right call.
