Standing seam is the premier choice in residential metal roofing. It is also the most expensive; around two or 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 and shakes.
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 $16.50 per square foot or $1,050 and $1,650 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 $33,000 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 or 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 $16.50 per sq. ft. to install standing seam metal roof on a typical house.
Asphalt shingles remain the most popular residential roofing material in America. While not the most durable option around, composition shingles aka fiberglass mat asphalt shingles are often the most economical option. Composition shingles typically make for a quick installation and continue to be improved upon.
Since the 1980s, fiberglass shingles have effectively displaced the traditional organic asphalt shingles that weren’t as durable. The cost of materials and installation has stayed relative to the rate of inflation.
As roofers discuss everything in terms of squares (100 sq.ft.), let’s use those rates. On average, a square of fiberglass architectural roofing shingles will run between $4.00 and $7.50 per square foot or $400 to $750 per square installed.
Note: In high cost of living areas such as Northern Virginia, Miami, Washington DC, NYC, Boston, Seattle, San Francisco, San Jose, and Los Angeles, the cost can easily exceed $600-$800 per square installed.
If choosing to go with a warrantied professional installation, on average, you can expect to pay between $8,000 and $15,000 for a typical 20-squares or 2,000 square foot roof. — This includes the cost of all the necessary materials and supplies, professional warrantied labor, tear off and disposal of the old roof, building permits and fees, and a minimum of 5-year workmanship warranty from the installer.
