Metal roofing systems are more expensive than most asphalt, wood or tile roofs. There are also differences between the costs of various metal roofs. Look at the differences between roofing systems to understand the costs and benefits between standard metal roofing and a standing seam metal roof.
Standing Seam Metal Roof
While prices will vary by location, a standing seam metal roof may run within $5 to $9 per square foot. Prices range by the overall quality of the system and the metal material used to manufacture the roof panels. Galvanized and copper are usually the most expensive choices in material selection. Copper can run up to $20 per square foot.
The labor involved in installing this type of roof is extensive and the system must be installed professionally. With advances in technology and on-site material forming, the price of standing seam panels is decreasing. Do make sure to get an up-to-date quote before thinking that this system is too expensive.
Agricultural Pole Barn Metal Roof
A pole barn or corrugated metal roof is normally the least expensive type of metal roof to have installed. Prices for steel sheeting run about $4 to $5 per square foot. This system is used more frequently in commercial applications, as it does not offer the stylish look most homeowners’ desire. Sheet metal is also not suitable for complex roofing systems, as it does not work well around penetrations or valleys.
While the labor costs of installing this type of system can be lower, metal sheeting installation uses exposed fasteners and elastomeric gasket material. The fasteners and gaskets require replacement due to corrosion and fatigue. Depending on the type of metal selected, recoating is often required. Coatings can be expected to last about 15 years.
Metal Shingle Roofs
Metal shingle systems may actually cost more than standing seam systems. In the highest quality range for aluminum, you can expect to pay up to $10 or more per square foot. Much of the cost will depend on the thickness of the material. While the style can provide a unique architectural appearance, you can face problems with uplift in winds. Metal shingles are additionally prone to damage and crushing. Metal shingles are rarely used for commercial roofing.
When comparing metal roof costs, you must also look at the life expectancy and maintenance costs involved over the life of the roof. While the standing seam metal roof is initially expensive, there are no exposed screws to corrode or begin to leak. This type of roof does not require repainting or recoating the way agricultural or pole barn roofs will.
