Asphalt shingle roofs are by far the most popular residential roofing system in Charleston and, indeed, across the United States. These roofs are exceptionally versatile, offering excellent style and durability at an affordable price.
What exactly does affordable mean when we're talking about a roof replacement? Today our Charleston, SC, roofing experts cover the topic of how much a new roof will cost when choosing asphalt shingles.
The Average Cost to Install a New Asphalt Shingle Roof in Charleston
The average cost of a new roof using asphalt shingles for homeowners in the Charleston area is between $3,300 to $19,600, depending on a wide variety of factors. In general, you can expect to pay between $3.30 and $5.60 per square foot for your new roof.
We realize this is a wide price range! To help you budget for a residential roof replacement, here are a few factors that impact the costs of asphalt shingles as your roofing material when getting a new roof.
How Roof Size Impacts Roof Cost
The biggest factor that will impact the cost of a replacement is the size of your roof.
Your expert Charleston roofer will use precise calculations to find the exact size of the roof, but you can get a general idea of costs vs. size by finding the square footage of the footprint of your home and comparing it to the numbers below.
-
1,000 square foot roof: $3,300 to $5,600
-
1,500 square foot roof: $4,950 to $8,400
-
2,000 square foot roof: $6,600 to $11,200
-
2,500 square foot roof: $8,250 to $14,000
-
3,000 square foot roof: $9,900 to $16,800
-
3,500 square foot roof: $11,550 to $19,600
Naturally, bigger homes with more roofing surface area will require a bigger budget to replace the roof.
The Type of Shingles Also Impacts Costs
There are three types of shingles currently available to Charleston residents. Depending on your budget, choosing different shingles can help you save money.
Three-Tab Asphalt Shingles
Three-tab shingles are the least expensive style of asphalt shingle. If you have limited funds or help from your insurance company, these can be the ideal solution for replacing your roof — especially for a property you're not looking to invest in for the long term.
These shingles are lightweight and energy-efficient, although not as durable or long-lasting as other shingle types.
Architectural Asphalt Shingles
Architectural shingles are the shingle of choice for most Charleston homeowners.
These shingles are thicker and far more durable than three-tab shingles. They also offer better curb appeal due to their wider range of colors and dimension-enhancing shapes and styles.
Architectural shingles strike the perfect balance between longevity, durability, and cost for the homeowner looking for a high-quality shingle at a mid-level price point.
Luxury Asphalt Shingles
As the name suggests, luxury asphalt shingles are a premium product.
These shingles are designed to mimic the look of more expensive roofing systems like cedar or slate at a fraction of the cost. While they're by far the most expensive asphalt shingle on the market, they're still far less expensive than the roofing materials they're made to emulate.
The Quality of Roofing Materials Is Also Important
Homeowners should also consider the quality of materials a roofing contractor uses, in addition to the type of shingle that's ideal for a new roof.

Other Important Considerations
The size of the roof and the type of shingle you choose are not the only factors that will determine the cost of your residential roof installation. Several other factors must be considered when calculating the final cost of your new roof. 
Roof Pitch
Roof pitch refers to the steepness of a roof.
Experienced Charleston roofers use a standardized pitch multiplier that helps determine how the pitch of the roof impacts the overall size of the roof. As a general rule, as a roof gets steeper, its surface area grows. Therefore, a steeper roof will be more expensive to install than a roof with a lower slope.
Roof Complexity
Things like roof dormers, skylights, chimneys, and vents can add to the complexity of the roof.
As a roof becomes more complex, it can become more expensive to install due to the need for more materials and the difficulty involved in properly installing the roof around these complexities.
Roof Height
Is your home a single-story or multi-story home? Even if a roof is the exact same size in surface area, a higher roof will cost more to install.
Labor Costs
All these factors affect labor costs and, ultimately, play a significant role in the cost of installing your new asphalt shingle roof.
When reviewing a roofing estimate, you can usually expect the cost of labor to make up 40%-60% of the total cost of your new roof. While comparing costs from one roofing company to another, be sure to look for itemized costs for materials and labor to compare expenses.
