They are usually galvalume or galvanized steel and have exposed fasteners. Flat sheets: These sheets have the lowest average cost of all metal roofing materials.Corrugated sheets: The rustic appearance of corrugated metal is accentuated by its exposed fasteners, which need to be maintained to prevent loosening and corrosion.Metal is available as flat or corrugated sheets as well as shingles and standing-seam panels. In addition to metal type, a metal roof’s cost is also determined by style.
The cost to remove and dispose of old shingles and underlayment is typically between $1 and $5 per square foot. Some metal roofing types can be installed over an old roof, but this won’t repair any existing decking damage. Sometimes a second layer of basic asphalt shingles can be installed over the first, but this is not recommended.
Average cost of metal roof install#
To install a new roof, existing roof materials will first need to be removed and any damage repaired. But they’re expensive and very heavy, often requiring roof reinforcement.ĭepending on your project’s specifics, the following factors may play into the total cost.
A basic asphalt shingle roof isn’t your only option. But shingles can be made of many materials. When most people think of a shingle roof, they’re imagining three-tab shingles made of asphalt. It’s also the most durable roofing metal, resistant to rust and corrosion. Copper: Copper represents the cost spectrum’s high end, but it has a unique, luxurious appearance.A lead roof can last 100 years or more, but the material is prone to denting. This outer coating is very corrosion-resistant. Lead: Lead tiles are typically composed of a stronger, metal-like steel or copper coated in lead.Stainless steel is the most expensive, but it also has the longest life span. Galvanized steel is in the midrange: it’s more durable than galvalume, but it can corrode over time. Galvalume is an aluminum-coated form of steel roofing that often comes painted. Steel : A steel roof can be made of galvalume, galvanized, or stainless steel.If properly maintained, it can last over a century. Zinc: Available as shingles and standing-seam panels, zinc forms a protective coating that reduces the visibility of scratches and prevents corrosion.The coating develops a patina over time, and these tiles can last up to 70 years. Tin: Typically, tin tiles are made from a steel core with a tin alloy coating called Terne.It’s lightweight, therefore less durable, but it’s recyclable and reflects solar heat. Aluminum: Aluminum is typically the least expensive metal roofing material, usually in the form of sheets or shingles.Below are the most common metal roofing materials for residential projects. The term “metal roofing” can cover everything from corrugated steel sheets to bespoke copper tiles. As you might imagine, high-quality metal and shingles will cost more, but they’re also more durable. The most relevant cost factor is the type of roofing materials you choose. Anything that increases the roofing project’s complexity will increase installation costs. Labor: Metal roofs are harder to install.Size: Larger roofs need more materials and labor to cover them.Material: The shingle material or metal type determines unit costs.Metal roofs typically cost more than shingle roofs, but the following factors determine your specific project price.
