Metal Roof Installation

Metal roofing costs more upfront than asphalt shingles, but the comparison isn't as simple as sticker price — a metal roof installed today can outlast two or three shingle roofs installed over the same period, which changes the real cost math once you factor in how long you plan to own the home.

What a Metal Roof Costs

The average metal roof runs $5,500 to $15,500 installed, with most homeowners landing just under $10,500. Price varies significantly by material:

Material	Cost per sq ft
Corrugated metal	$4–$7
Metal slate (stone-coated)	$5–$12
Zinc	$6–$10
Steel	$6–$16
Standing seam (aluminum or steel)	$8–$14
Aluminum	$8–$12
Copper	$16–$30

Labor makes up as much as two-thirds of the total cost — more than a typical shingle job — because metal roofing requires specialized tools, precise seaming or fastening, and often more time on steep or complex pitches. Roof pitch, existing underlayment compatibility, and whether you choose hidden versus exposed fasteners all move the final number too.

Metal vs. Asphalt Shingle

The two materials solve different problems, and the right choice usually comes down to timeline and priorities rather than one being objectively better:

• Lifespan. Standing seam metal commonly reaches 40–70 years with minimal maintenance. Architectural shingles run 25–30 years under good conditions.
• Upfront cost. Shingles are cheaper to install — often by a factor of 2 to 3 — which matters if you're not planning to stay in the home long-term or you're working with a tighter budget.
• Storm and wind performance. Interlocking metal panels handle high wind and shed snow better than shingles, with fewer exposed seams for water to find a way in.
• Noise and expansion. Metal roofs are louder in heavy rain without added insulation, and they expand and contract more with temperature swings — both manageable with proper installation, but worth knowing going in.
• Maintenance. Once installed correctly, metal needs very little upkeep. Exposed-fastener systems are the exception — the gasket seals around fasteners compress and crack over time and need occasional attention, which is why standing seam (no exposed fasteners) is generally the better residential choice over corrugated panel systems.

For a home you plan to own for decades, or in an area that sees serious storm activity, the higher upfront cost of metal often pencils out over the life of the roof. For a shorter ownership horizon, architectural shingles remain the more practical choice.

The Installation Process

Metal roofing installs differently than shingles, which is part of why it takes a crew that specializes in it:

1. Measurement and panel fabrication. Standing seam panels are often custom cut or fabricated to the exact dimensions of each roof plane rather than pulled from standard stock sizes, which minimizes seams and waste.
2. Underlayment compatibility check. Metal needs a underlayment rated for the higher heat and different moisture behavior of a metal surface — reusing shingle-rated underlayment underneath metal panels is a common shortcut that shortens the roof's effective life.
3. Panel installation and seaming. Panels are set in sequence and seamed (standing seam) or fastened (exposed-fastener systems) according to the manufacturer's spec, with careful attention to overlap and expansion allowance so the panels can move with temperature changes without stressing the seams.
4. Trim, flashing, and penetration detail work. Chimneys, vents, and skylights all need custom-fitted metal flashing — this detail work is where installation quality shows up most, since these are the highest-risk points for a future leak.
5. Final inspection. Seams, fasteners, and flashing get checked before the crew leaves, since a metal roof installed correctly should need very little attention for decades.

Common Myths About Metal Roofs

A few misconceptions come up often enough to be worth addressing directly. Noise: a properly installed metal roof over solid decking and underlayment is not noticeably louder in rain than a shingle roof — the "tin roof in a rainstorm" reputation mostly comes from older exposed-fastener installations over open framing without a solid deck underneath. Lightning: metal roofing does not attract lightning any more than other roofing materials; if anything, metal is non-combustible, which is a safety advantage, not a risk. Cost over time: the higher sticker price is real, but so is the lower total cost of ownership for anyone keeping the home long enough to avoid a second or third shingle replacement over the same period.
