Metal roofs are becoming increasingly popular with many savvy homeowners and it’s not hard to see why; compared to the more traditional approaches like asphalt shingles and cedar shingles and shakes, metal offers many important advantages including a significantly longer lifespan, low maintenance, excellent durability, and superior energy efficiency.
On average, you can expect to pay between $8.50 to $15.50 per square foot to install a metal roofing system on a typical residential house. For example, an average-sized single-story house with a fairly simple roof shape measuring about 2,000 sq. ft. or 20 squares could cost anywhere from $17,000 to $31,000 for the installation of a high-end metal roofing system such as stamped metal shingles or tiles and standing seam metal roofs.
There are not many roofing materials that can match the longevity, durability, malleability, flexibility, resiliency, and cost-effectiveness of Zinc.
Not even aluminum or copper! Zinc roofs are known to last for hundreds of years, even in the most extreme environments.
How Much Does Zinc Roof Cost?
Truly unmatched durability, longevity, and classic beauty — that’s what zinc roofing offers to a homeowner. — At $12.50 to $18.50 per sq. ft. installed, it is the kind of value that is simply unmatched in all other roofing materials.
Zinc — Most Amazing Building Envelope Material You Never Heard of!
In the US, the whole idea of using Zinc as a roofing or cladding material for a house may sound other-worldly.
Aluminum and steel dominate residential metal roofing market, while asphalt shingles are by far the most popular overall roofing material.
When you also factor in natural slate, clay tiles and cedar/wood roofing options, Zinc barely registers on most people’s radars. Though this trend is changing, slowly.
Standing seam is the premier choice for metal roofing. It is also the most expensive; around two to three times the cost of corrugated metal panels and asphalt shingles, and about 10% to 20% more than metal shingles like interlocking steel and aluminum tiles.
Standing seam offers unbeatable value (through durability, longevity, energy-efficiency, and style) that is hard for any other roofing material to match. Let’s explore this in further detail:
The current national average cost to install a standing seam metal roof on a typical single family house can range between $10.50 and $15.50 per square foot or $1,050 and $1,550 per square. This assumes a professional and warrantied installation of G-90 galvanized steel or Galvalume 26-gauge or 24-gauge (better) steel panels finished with the factory applied Kynar 500 paint finish. Aluminum panels finished with Kynar 500 paint are also an option and may cost slightly more than steel.
When estimating the total cost of a project: For a typical 2,000 square foot roof, it will cost between $21,000 and $31,000 for a complete installation including all the materials and supplies, professional application, product and workmanship warranty, and any necessary building permits for the job. Removal and disposal of the old roof may be extra, depending on the extent of additional work required to complete the job.
G-90 Galvanized Steel is the most popular or most-often used option for residential standing seam roofs. The “G” here refers to the amount of the zinc plating, as in .90oz per square foot.
Did you know? Standing Seam is also available in Aluminum, Galvalume, G-90 galvanized Steel, Zinc, Copper, and Stainless Steel.
While technically, aluminum is more expensive than steel, the reality is the costs aren’t noticeably different when considering the ultimate cost of a new metal roof to homeowners when installed by professionally trained metal roofing contractors.
If the materials were not coated and not finished with the high-end factory paint finish like Kynar 500, then perhaps the higher cost of aluminum would be something of note. In the current market, they are virtually the same cost.
Cost of Materials and Important Nuances on Pre-Cut vs. Custom-Fabricated Metal Panels
Standing seam metal panels and trim will cost between $3.50 and $6.50 per sq. ft. for made-to-order aka custom fabricated metal panels, depending on the overall order size, project location, and contractor’s supplier relationship.
In terms of steel coating quality and thickness or gauge, a 26-gauge (good), 24-gauge (better), or 22-gauge (best) Galvalume coated steel would be a better and a longer-lasting option compared to G-90 galvanized steel, especially in the heavy salt-spray, marine environments. For most other environments, G-90 galvanized steel panels will work just fine. Be sure to look for Kynar 500 paint finish, whether you go with Galvalume or galvanized steel panels.
Total Cost per Square Foot Installed
A qualified contractor will likely have real metal samples, a brochure or catalog to show off all the possibilities in terms of colors and profiles, as well as any available custom colors or metal alloys like aluminum and zinc. They’ll provide all the information that backs up their work.
Therefore, if going with the national average, their prices will normally fall in the range of $10.50 to $15.50 per sq. ft. to install standing seam metal roof on a typical house.
