Metal Roof vs Asphalt Shingles in Summerville SC

By Dubya Roofing & Gutters | August 23, 2026 | 8 min read

For Summerville homeowners, asphalt shingles typically cost $4-$7 per square foot installed while metal roofing runs $8-$14 per square foot, but metal roofs last 40-70 years compared to asphalt's 15-30 years, making metal a better long-term investment despite the higher upfront cost.

What Are the Main Differences Between Metal Roofs and Asphalt Shingles in Summerville?

Metal roofing and asphalt shingles differ significantly in durability, lifespan, and performance in Summerville's humid subtropical climate. Metal roofs consist of steel, aluminum, or zinc panels that interlock or overlap, creating a continuous protective barrier that reflects heat and resists moisture penetration. Asphalt shingles, on the other hand, are individual overlapping tiles made from fiberglass or organic mat coated with asphalt and mineral granules.

In Summerville's climate—where summer temperatures regularly exceed 90°F and humidity levels stay high year-round—these material differences matter considerably. Metal roofing excels at reflecting solar radiation, keeping attics 10-25% cooler than asphalt alternatives. This translates directly to lower cooling costs during Summerville's long, hot summers. Asphalt shingles absorb more heat and are more susceptible to moss and algae growth in the area's humid conditions, though algae-resistant shingles are available at a premium.

How Long Do Metal Roofs Last Compared to Asphalt Shingles in South Carolina?

Metal roofs typically last 40-70 years in South Carolina's climate, while asphalt shingles last 15-30 years depending on quality and maintenance. The longevity difference is substantial when you consider that Summerville homeowners might need to replace an asphalt roof two or even three times during the lifespan of a single metal roof installation.

Several factors unique to Orangeburg County and the surrounding Lowcountry region affect these timelines. The combination of intense UV exposure, high humidity, occasional tropical storms, and temperature fluctuations causes asphalt shingles to deteriorate faster than in more moderate climates. The granules protecting asphalt shingles gradually wash away during heavy rains, exposing the underlying material to accelerated aging. Metal roofing, conversely, handles these conditions exceptionally well—the painted or coated finishes are engineered to resist fading, and the solid construction stands up to wind and storm damage that would tear away individual shingles.

Just as Dubya Roofing & Gutters uses a KWM seamless gutter machine to fabricate gutters on-site without vulnerable seams, metal roofing systems minimize weak points through their interlocking panel design, creating a roof system built to last decades in Summerville's demanding environment.

What Does Metal Roofing vs Asphalt Shingles Cost in Summerville SC?

The installed cost for asphalt shingles in Summerville typically ranges from $4-$7 per square foot, while metal roofing costs $8-$14 per square foot depending on the metal type and profile selected. For an average 2,000 square-foot roof, that translates to $8,000-$14,000 for asphalt versus $16,000-$28,000 for metal.

However, these upfront numbers don't tell the complete financial story. When you calculate the cost-per-year of ownership, metal roofing becomes considerably more competitive. A $20,000 metal roof lasting 50 years costs $400 annually, while a $10,000 asphalt roof lasting 20 years costs $500 per year—and that doesn't account for the labor costs of multiple re-roofing projects over the same timeframe.

Additionally, metal roofs deliver measurable energy savings in Summerville's climate. Homeowners typically see 10-25% reductions in cooling costs due to metal's reflective properties, which can amount to $200-$500 in annual savings depending on home size and insulation. Many insurance companies also offer premium discounts for metal roofing due to its superior wind and fire resistance—an important consideration in a region that occasionally faces hurricane threats.

Which Roof Type Performs Better in Summerville's Weather Conditions?

Metal roofing performs better in Summerville's hot, humid climate and severe weather conditions, offering superior wind resistance, heat reflection, and moisture management compared to asphalt shingles. This performance advantage becomes especially important during the hurricane season that affects the South Carolina Lowcountry from June through November.

Metal roofs are rated to withstand winds up to 140 mph when properly installed, while standard asphalt shingles typically handle 90-110 mph winds. During severe thunderstorms and tropical systems that periodically impact Summerville and Orangeburg County, this difference can mean the distinction between minor repairs and complete roof replacement. The interlocking design of metal panels creates a continuous surface that wind cannot easily penetrate or lift, whereas individual shingles present numerous edges where wind can gain purchase.

Regarding heat and moisture—two constant factors in Summerville's climate—metal roofing again demonstrates clear advantages. The reflective surface keeps homes cooler, reducing the burden on HVAC systems during brutal summer months. Metal also sheds water immediately rather than absorbing it, preventing the moisture-related deterioration that plagues asphalt shingles in humid environments. This quick water shedding works particularly well when paired with quality gutter systems that channel water away efficiently.

What Are the Aesthetic and Resale Value Considerations?

Both metal roofing and asphalt shingles can enhance Summerville home values, but they appeal to different buyer preferences and architectural styles. Asphalt shingles offer the traditional look that many buyers expect, with a wide variety of colors and styles including architectural shingles that mimic the appearance of wood shake or slate. Metal roofing provides a more distinctive appearance that signals quality and durability to informed buyers.

In Summerville's diverse housing market—ranging from historic downtown homes to newer suburban developments—architectural compatibility matters. Traditional Southern homes with classic styling often look best with dimensional asphalt shingles that complement their design heritage. Contemporary homes, farmhouse-style properties, and energy-efficient builds can showcase metal roofing as a feature that aligns with their modern aesthetic.

Real estate data suggests that metal roofing recoups 85-95% of its cost at resale in Southern markets, while asphalt shingle replacement typically returns 60-70%. The superior longevity appeals to buyers who calculate long-term ownership costs. A home with a recently installed metal roof effectively comes with a lifetime roofing solution already in place—a powerful selling point that can differentiate a property in competitive markets like Summerville's growing residential areas near Nexton and Carnes Crossroads.

Which Roofing Option Is Right for Your Summerville Home?

The right choice between metal roofing and asphalt shingles depends on your budget, how long you plan to stay in your home, and your priorities regarding energy efficiency and maintenance. Homeowners planning to stay in their Summerville residence for 15+ years typically benefit most from metal roofing's longevity and energy savings, while those with shorter timelines or tighter budgets may prefer asphalt shingles' lower initial investment.

Consider metal roofing if you want maximum durability, the lowest lifetime cost, significant energy savings, and superior storm protection—all important factors in Orangeburg County's climate. Choose asphalt shingles if you need to minimize upfront costs, prefer traditional aesthetics, or plan to sell within 10-15 years before the longevity advantage of metal becomes fully realized.

Frequently Asked Questions

Is metal roofing louder than asphalt shingles during rain in Summerville?

Modern metal roofing installed over solid decking with proper insulation is not significantly louder than asphalt shingles during rainfall. The solid substrate and attic insulation dampen sound effectively, making interior noise levels comparable between both roofing types during Summerville's frequent afternoon thunderstorms.

Can you install metal roofing over existing asphalt shingles in South Carolina?

Yes, metal roofing can often be installed over one layer of existing asphalt shingles in South Carolina, which saves on tear-off costs and landfill waste. However, the existing roof must be in reasonable condition without significant damage, and local building codes in Summerville must be followed regarding maximum roof layers.

Do metal roofs attract lightning more than asphalt shingle roofs?

Metal roofs do not attract lightning any more than asphalt shingle roofs, as lightning strikes the highest point in an area regardless of material. If lightning does strike a metal roof, it actually disperses the energy more safely than asphalt and is non-combustible, making it a safer option overall.

Will a metal roof increase my homeowners insurance costs in Summerville?

Metal roofs typically decrease homeowners insurance costs in Summerville rather than increase them. Most insurance companies offer premium discounts of 10-20% for metal roofing due to its superior wind resistance, fire resistance, and longevity compared to asphalt shingles.

How much cooler does a metal roof keep a house compared to asphalt shingles in summer?

Metal roofs can reduce attic temperatures by 10-25% compared to asphalt shingles during Summerville's hot summers. This translates to cooling cost savings of 10-25% depending on your home's insulation, typically amounting to $200-$500 annually for most Summerville homeowners.
