Metal roofs are becoming more popular in Charleston due to their versatility and durability. While they’re overall more expensive than the more common asphalt shingle roofs, they offer a good bang for your buck in terms of life expectancy and design choices.
Average Metal Roof Cost by Square in Charleston
When roofing contractors discuss the size of a roof, they talk about squares. A square is simply a 10 foot by 10 foot area, which means it’s 100 square feet. The average cost of a metal roof in Charleston is $630-$980 per square or $6.30-$9.80 per square foot.
How Material Affects Metal Roof Cost
There are a huge variety of metal roofing systems available on the market made with different processes and materials. The specific metal roofing system you choose will directly impact the cost of your new metal roof.
Corrugated Metal Roof
Corrugated metal roofs are made from galvanized steel that is rolled into U or R channels. They are the cheapest residential metal roofing material available in Charleston.
Aluminum Roof
Aluminum is a step up from corrugated metal in both price and quality. While aluminum roofs lack a bit in style points they make up for that in durability offering fire, wind, and impact resistance. They’re also very eco-friendly as a recyclable material.
Steel Roof
Steel roofs are arguable one of the best options for a residential metal roof. They’re middle of the road as far as metal roof costs are concerned, but offer above average durability and life expectancy. They can be endlessly customized to give your roof a unique look while still falling at a mid-level affordability and lasting 40-60 years on average.
Standing Seam Roof
Standing seam roofs are one of the most common types of residential metal roofs. They come in many different colors, lengths, and thicknesses and are both versatile and durable. 
Copper Roof
Copper roofs are the most expensive metal roofing system on the market, but they also will greatly increase your property value should you choose to go with a copper roof. They’re beautiful, durable, and energy efficient.
Other Factors that Impact Metal Roof Cost
Your chosen roofing system isn’t the only thing that will affect the cost of a new metal roof installation in Charleston. There are numerous factors that come together to ultimately determine the final cost of your roof.
Size of Home
The size of your home is one of the most significant factors that determines the cost of your metal roof installation. This directly impacts the amount of materials and labor necessary to complete the job, so it’s arguable the most important factor in deciding the cost of the roof aside from the type of roof system chosen. The cost for a metal roof installation in Charleston by home size is as follows:
- 1000 square foot home: $6300 – $9800
- 1500 square foot home: $9450 – $14,700
- 2000 square foot home: $12,600 – $19,600
- 2500 square foot home: $15,750 – $24,500
- 3000 square foot home: $18,900 – $29,400
Single or Multistory
Whether your home is a single story or multistory home largely impacts the labor costs of installing your metal roof. There is added complexity when having to navigate more than one story as well as added danger, so your roofing contractor will need to spend more time working carefully to install your roof. 
Pitch
The pitch of your roof refers to how steep the roof is, and this impacts the cost of your metal roof installation in a few ways. First, a steeper roof is a more dangerous roof, which, again, means your roofer will need to take more time installing the roof while following safety guidelines. Additionally, roofing contractors in Charleston use what’s called a “pitch multiplier” to accurately assess the size of your roof. While the square footage of your home can give a general idea of the size of your roof, it doesn’t account for pitch which can add significantly to the surface area of the roof depending on how steep it is. Pitch is written as rise/span with each pitch having a specific multiplier.
- A 3/12 roof has a 14 degree slope and uses a pitch multiplier of 1.031. This means that a 1000 square foot home with a 3/12 roof has a surface area of 1031 square feet. Not much change, right?
- A 9/12 roof has a 36.9 degree slope and uses a pitch multiplier of 1.25. This means that a 1000 square foot home with a 9/12 roof has a surface area of 1250 square feet. You just added 2.5 squares to that roof which is $1575 – $2450 more in Charleston.
Complexity
If your roof has a lot of accessories like chimneys, vents, and other design elements it will cost more to install a metal roof.
New Installation or Replacement
New installation metal roofs are less expensive than a roof replacement. This is because when a roof is replaced the old roof must be torn off before the new roof can be installed which adds to the labor costs of the metal roof installation.
