The 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, meanit'sng 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. However, depending on the type of metal you choose, the costs can be higher or lower.
How Material Affects Metal Roof Repair or Replacement Cost
There is a significant 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. This material is 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 arguably one of the best options for a residential metal roof. They're the "middle-of-the-road" as far as metal roof costs are concerned but offer above-average durability and life expectancy.
Roofs made of steel can be endlessly customized to give your roof a unique look while still falling at 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 significantly increase your property value. Roofs made of this material are beautiful, durable, and energy efficient.
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.
The Size of Your Home
The size of your home is one of the most significant factors that determine the cost of your metal roof installation.
Your home's size directly impacts the amount of materials and labor necessary to complete the job, so it's one of the most important factors 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:
-
1,000 square foot home: $6,300 – $9,800
-
1,500 square foot home: $9,450 – $14,700
-
2,000 square foot home: $12,600 – $19,600
-
2,500 square foot home: $15,750 – $24,500
-
3,000 square foot home: $18,900 – $29,400
Use the numbers above for an estimated cost to replace your roof with metal materials. However, to get a detailed estimate, schedule a roof inspection with local Charleston, SC, roofing contractors.
Single or Multi-Story Homes
Whether your home is a single-story or multi-story home largely impacts the labor costs of installing your metal roof.
There is added complexity when navigating more than one story, as well as added danger and risk of injury. So your roofing contractor will need to spend more time working carefully to install your roof.
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 more dangerous, which 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 assess the size of your roof accurately. 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 roof's surface area, depending on how steep it is.
Pitch is written as rise/span, with each pitch having a specific multiplier. For example:
-
A 3/12 roof has a 14-degree slope and uses a pitch multiplier of 1.031. This means that a 1,000-square-foot home with a 3/12 roof has a surface area of 1031 square feet. Not much change, right?
-
However, a 9/12 roof has a 36.9-degree slope and uses a pitch multiplier of 1.25. This means a 1,000-square-foot home with a 9/12 roof has a surface area of 1,250 square feet.
The difference in pitch between these two homes adds 2.5 squares to that roof, which can cost between $1,575 – $2,450 more for a roof replacement in Charleston.
Complexity
If your roof has many accessories like chimneys, vents, and other design elements, it will cost more to install a metal roof. Navigating around different structures requires extreme caution and can require additional materials.
New Installation vs. A Roof Replacement
Are you building a home and installing a new roof? 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. So, starting with a metal roof on a new-construction home will be a lower cost than replacing an asphalt shingle roof with a metal roof for the same home down the road.
