Living in the South Carolina Lowcountry means your roof faces a punishing combination of humidity, wind, rain, and salt air that most parts of the country never experience. Choosing the wrong roofing material here does not just shorten your roof’s lifespan — it can lead to mold, leaks, and costly emergency repairs within just a few years of installation.
At Right Hand Roofing, we have installed and inspected thousands of roofs across Summerville, Nexton, Cane Bay, Goose Creek, and the greater Charleston area. This guide ranks the best roofing materials for the Lowcountry climate based on real-world performance, not manufacturer marketing.

Before comparing materials, you need to understand what your roof is actually up against. The Lowcountry is one of the most demanding climates for roofing systems in the entire United States, and here is why.
Average relative humidity in the Summerville and Charleston area ranges from 70% to 90% throughout the year. This constant moisture exposure accelerates algae growth, promotes mold and mildew on roofing surfaces, traps moisture beneath improperly ventilated roof systems, and breaks down adhesive bonds on cheaper shingle products. Humidity is the silent destroyer of Lowcountry roofs. Materials that perform well in dry climates often fail prematurely here.
The Lowcountry receives over 50 inches of rain per year, with intense downpours common during summer months. Your roof needs to shed water quickly and reliably. Poor drainage design or materials that absorb moisture will deteriorate faster than you expect.
Six months of every year, your roof is at risk from tropical storms and hurricanes. South Carolina building codes now require roofing systems to withstand significant wind loads, and for good reason. The 2024 and 2025 hurricane seasons reminded every Lowcountry homeowner why wind resistance is not optional — it is essential.
Homes within 10 to 15 miles of the coast are exposed to salt-laden air that corrodes untreated metals, degrades certain coatings, and accelerates wear on fasteners and flashing. Even homes in Summerville, which sits roughly 25 miles inland, can experience some salt air effects during strong onshore winds.
Summers regularly push above 90 degrees Fahrenheit, with roof surface temperatures reaching 150 degrees or higher. This thermal stress causes expansion and contraction cycles that weaken poorly designed roofing materials over time. UV exposure also degrades shingle granules and sealant strips.
Based on our experience installing and maintaining roofs across the Charleston metro area, here are the top five roofing materials for this climate, ranked by overall performance, value, and durability.
For most Lowcountry homeowners, architectural asphalt shingles remain the best combination of performance, appearance, and value. However, not all architectural shingles are created equal.
We recommend and install Owens Corning Duration shingles with SureNail Technology as our top choice for this climate. Here is why:
As an Owens Corning Preferred Contractor (ID: 244515), Right Hand Roofing can offer enhanced warranty coverage that is not available through non-certified installers. This matters because even the best materials underperform when installed incorrectly.
Standing seam metal roofing is the premium choice for Lowcountry homes, offering exceptional longevity and wind resistance. Panels interlock vertically with raised seams that keep fasteners hidden and protected from the elements.
The primary drawback is cost. Standing seam metal roofing typically runs two to three times the cost of architectural shingles. For coastal homes within a few miles of the ocean, make sure the metal is properly coated or rated for salt air exposure. Galvalume or aluminum panels with Kynar 500 finishes perform best near the coast.
Metal shingles offer a middle ground between traditional shingle aesthetics and metal roofing performance. They are stamped to resemble slate, wood shake, or traditional shingles while delivering many of the benefits of metal.
Metal shingles are a solid choice for homeowners who want the look of a traditional roof with improved durability. Installation requires a contractor experienced with the product, as improper installation can lead to noise issues and reduced wind performance.
Designer or luxury asphalt shingles, such as the Owens Corning Berkshire or TruDefinition lines, offer enhanced aesthetics that mimic the appearance of natural slate or wood shake. They use thicker construction and heavier base mats for improved performance.
Designer shingles make sense for higher-value homes where curb appeal and resale value are priorities. They perform well in the Lowcountry climate with proper ventilation and installation.
Concrete tile roofing offers excellent longevity and a distinctive appearance that suits certain architectural styles common in the Lowcountry, particularly Mediterranean and Spanish-influenced designs.
The major concern with concrete tile in our area is weight. Your roof structure must be engineered to support the load, which adds to project cost. Tiles can also crack under impact from falling debris during storms, and individual tile replacement can be difficult.
Just as important as knowing what works is understanding what does not. These materials consistently underperform in our climate.
Basic 3-tab shingles are the lowest-cost option on the market, and their performance reflects that price point. In the Lowcountry, 3-tab shingles are a poor investment for several reasons:
If a contractor quotes you 3-tab shingles for a Lowcountry home, consider that a red flag about their understanding of local conditions.
Standard galvanized steel without proper coatings will corrode quickly in salt air environments. If you are considering metal roofing within 15 miles of the coast, make sure the product is specifically rated for coastal exposure. Aluminum or properly coated Galvalume panels are the safer choice.
Wood shake may look beautiful, but it is a poor match for the Lowcountry. Our humidity promotes rapid moss and algae growth on wood surfaces, moisture absorption leads to rot and decay, wood shake requires significantly more maintenance than alternatives, and fire risk is elevated. Additionally, many insurance companies charge higher premiums or refuse to cover wood shake roofs.
If you have driven through any Lowcountry neighborhood, you have seen roofs with dark black streaks running down the slope. Those streaks are not dirt — they are colonies of Gloeocapsa magma, a type of blue-green algae that thrives in warm, humid environments.
South Carolina’s climate is essentially a perfect breeding ground for roof algae. Once established, algae does more than look bad:
Owens Corning’s StreakGuard technology embeds copper-infused granules throughout the shingle surface. Copper is a natural algae inhibitor. As rain washes over the roof, trace amounts of copper ions flow across the surface and prevent algae colonies from establishing. This protection lasts for the life of the shingle.
In a climate like ours, choosing shingles without algae resistance is choosing to have an ugly roof within three to five years. StreakGuard is not a luxury feature in the Lowcountry — it is a necessity.
Understanding wind ratings helps you make informed decisions and ensures your roof meets South Carolina building code requirements.
Shingle wind ratings indicate the maximum sustained wind speed the product is warranted to withstand when installed according to manufacturer specifications. The 130 MPH rating on Owens Corning Duration shingles means the product has been tested and warranted to remain sealed and in place during winds up to that speed.
South Carolina adopted updated building codes that require roofing materials to meet specific wind resistance standards based on your location. Much of the Lowcountry falls within zones that require materials rated for 110 MPH or higher basic wind speeds, with higher requirements closer to the coast.
This means choosing a roofing material with a 130 MPH wind rating is not just smart — in many parts of the Lowcountry, it is code-required. Owens Corning Duration shingles with SureNail Technology meet these requirements, which is one reason they are our top recommendation.
A wind rating is only as good as the installation behind it. The best shingles installed incorrectly will fail in moderate winds. This is why choosing a certified, experienced contractor matters as much as choosing the right material. As a licensed South Carolina roofing contractor (License #65625) and Owens Corning Preferred Contractor, Right Hand Roofing follows manufacturer installation protocols precisely to ensure your warranty and wind protection are fully intact.
Standing seam metal roofing offers the longest lifespan at 40 to 70 years. However, architectural asphalt shingles like the Owens Corning Duration provide 25 to 30+ years of performance at a significantly lower cost, making them the best value for most homeowners.
Metal roofs make sense for homeowners who plan to stay in their home long-term and want maximum durability. The upfront cost is two to three times higher than asphalt, but the lifespan is roughly double. If you plan to sell within 10 to 15 years, architectural shingles typically offer better return on investment.
Choose shingles with built-in algae resistance like Owens Corning’s StreakGuard technology. Copper-infused granules prevent algae growth for the life of the shingle. Avoid pressure washing existing algae stains, as this can damage shingles and void warranties. A soft wash with appropriate cleaning solution is the safer approach.
Most of the Summerville area requires roofing materials rated for at least 110 MPH basic wind speed per South Carolina building codes. We recommend 130 MPH rated products like Owens Corning Duration shingles to provide an additional safety margin during hurricane season.
While it is technically possible in some situations, we generally do not recommend it. Installing metal over existing shingles can trap moisture, void warranties, and hide underlying damage. A full tear-off allows us to inspect the roof deck, replace damaged decking, and install proper underlayment for maximum performance.
Roof replacement costs vary based on size, pitch, material choice, and complexity. Architectural asphalt shingles typically range from $8,000 to $15,000 for an average-sized home, while standing seam metal roofing can range from $18,000 to $35,000 or more. We provide free inspections and detailed estimates. Call (843) 696-9307 for a quote.
Lighter colors reflect more solar heat and can reduce cooling costs. However, modern shingles with reflective granule technology — including several Owens Corning Duration colors — provide improved energy performance even in darker shades. Your choice should balance energy efficiency with neighborhood aesthetics and HOA requirements.
Yes. Many insurance companies offer discounts for impact-resistant shingles (Class 4 rated) and may charge higher premiums for materials like wood shake. Choosing a high-wind-rated product like Owens Corning Duration shingles can also help with insurance approval and may reduce your premium. Contact your insurance agent before making a final material decision.
The best roofing material in the world will underperform if it is not installed correctly. Right Hand Roofing combines the best products with certified installation expertise to give your home the protection it deserves.
As an Owens Corning Preferred Contractor (ID: 244515), licensed in South Carolina (License #65625), BBB member, and carrying $1M+ in insurance coverage, we stand behind every roof we install.
