Side by side
How do metal and asphalt shingle roofs compare?
Metal typically costs two to three times more up front and carries a much longer estimated life. Shingles cost less today and suit shorter ownership.
| Factor | Metal roof | Asphalt shingles |
|---|---|---|
| Estimated life (InterNACHI) | 40 to 80 years | About 20 years for 3-tab; about 30 for architectural |
| Other life estimates | 30 to 50+ years (Metal Roofing Alliance) | 15 to 20 years for 3-tab; 20 to 30 for architectural (HomeGuide) |
| Weight per 100 sq ft | Steel 80 to 125 lb; aluminum 40 to 70 lb | 275 to 425 lb |
| National installed cost, 2026 | Standing seam $9 to $16 per sq ft; metal shingles $6 to $14 (HomeGuide) | $3 to $6 per sq ft (HomeGuide) |
| Wind ratings | Set by each product; one stone-coated steel panel is warranted for wind up to 120 mph (DECRA) | Lab classes ASTM D3161 Class F and ASTM D7158 Class H; GAF cites 110 and 150 mph lab results |
| Impact rating | UL 2218 Class 4 on some products | Class 4 shingles are also sold |
| Routine care | Standing seam hides its fasteners; exposed-fastener panels need yearly screw checks (Sheffield Metals) | Replace lifted or missing shingles; watch flashing and pipe boots |
| Going over the old roof in NJ | Over one sound asphalt layer only | Over one sound layer only |
| Federal tax credit in 2026 | None | None |
Where the numbers come from: life spans from InterNACHI, the Metal Roofing Alliance and HomeGuide. Weights are from Classic Metal Roofing Systems, a metal roofing maker, so read them with that in mind.
Costs come from HomeGuide’s metal roof guide. Shingle wind classes come from the Asphalt Roofing Manufacturers Association, and the impact classes from UL 2218 as summarized by GAF.
Weather
Which roof handles New Jersey weather better?
Both hold up when they are installed well, but they fail in different places. Shingles are most exposed to wind lift and ice at the edges. Metal’s weak points are its flashings, its fasteners and, near the shore, its metal and finish.
Nor’easters and wind
The Office of the New Jersey State Climatologist at Rutgers says coastal storms are most frequent from October to April, and that a winter rarely passes without at least one significant one (Rutgers climate overview).
Shingle wind classes are lab tests, not promises. New Jersey also has no single statewide design wind speed; DCA Bulletin 19-1 tells designers to pull site-specific values for the exact address. Ask any roofer which class the shingle carries and how it will be fastened.
Snow and ice dams
Ice dams start inside the house. Heat escaping into the attic melts snow on the upper roof, the water refreezes at the colder edge, and the ice traps water that can back up under the roofing (University of Minnesota Extension).
A slick metal roof can shed snow sooner, but neither roof cures heat loss. The DOE’s Building America Solution Center puts air sealing and insulation first, with ventilation as the third defense. We install an eave membrane under both roof types as standard practice; New Jersey code requires one only in Sussex County.
Salt air at the shore
Near salt water, the metal and finish must match the warranty’s distance rules. Metal Sales says its Galvalume warranty does not apply within 1,500 feet of salt water. Sheffield Metals reports that Galvalume warranties commonly stop short of homes within 1,500 feet of breaking surf, 800 feet of a large bay or 400 feet of salt marsh. Our guide to metal roofs at the Jersey Shore covers the options.
The honest answer
When are shingles the better choice?
When you plan to move within several years, when the up-front budget is tight, or when rules or a shared roofline call for shingles. In those cases we will price an asphalt roof and tell you so.
- You expect to sell before shingles would wear out. A buyer may not pay you back for decades of roof life you leave behind.
- The roof needs replacing now and the budget is fixed. At $3 to $6 per square foot nationally, asphalt does the job for far less up front.
- An HOA, a condo board or a historic preservation commission reviews exterior changes. New Jersey’s Municipal Land Use Law lets towns review major exterior alterations in designated historic districts (NJ Historic Trust).
- You own an attached home whose roof runs straight into the neighbors’. Matching the material keeps the roofline uniform, and attached homes generally need a construction permit to re-roof.
Shingles done right still need balanced attic ventilation, an eave membrane and good flashing. Our asphalt shingle roofing page explains how we build one. We are a metal-first company, but we would rather install the roof that fits your plans.

The long view
What does a 30-year view look like?
Over 30 years, a 3-tab roof would likely be replaced once, an architectural shingle roof would reach the end of its estimated life, and a metal roof would still be well inside its range. The dollars below use today’s national prices only.
| Roof | Estimated life (InterNACHI) | Roofs bought in 30 years | Today’s national cost, 2,235 sq ft roof |
|---|---|---|---|
| 3-tab asphalt | About 20 years | Two | About $13,400 to $26,800 for two roofs |
| Architectural asphalt | About 30 years | One, with the next one due | About $6,700 to $13,400, then the next roof |
| Standing seam metal | 40 to 80 years | One | About $20,100 to $35,800 |
HomeGuide’s asphalt range covers both shingle types, so the table uses it for each. The math is simple: one asphalt roof runs about $6,700 to $13,400 for this size, and a 3-tab roof bought twice doubles that.
What the table leaves out matters. Future prices, a second tear-off, repairs along the way and how long you stay can all swing the result. Resale value is left out too, because we have no sourced figure for it.
The takeaway: over very long ownership, one metal roof can land close to the cost of two shingle roofs. Over shorter ownership, shingles usually cost less. See our metal roof cost guide for the price drivers behind these ranges.
Re-roofing rules
Can either roof go over the old shingles?
Only over one sound layer. New Jersey’s Rehabilitation Subcode requires a tear-off when the roof has two or more layers, wood shakes, slate or tile, or a deteriorated base.
That rule is N.J.A.C. 5:23-6.4(e)7 (NJ DCA text). The model code carves out an exception for standing seam systems on their own supports, but New Jersey’s text does not repeat it. Our page on metal roofs over shingles explains the deck checks and trade-offs.
Either way, a detached one- or two-family house can take a new roof covering without a construction permit, because the state files that work under ordinary maintenance. Attached homes generally need one.
Common myths
Is a metal roof noisy, and does it attract lightning?
No on both counts, with one condition on noise. The Metal Roofing Alliance says rain noise differs little from other roofs when metal goes over solid decking with insulation. We install over a solid deck, and we still do not promise silence.
Lightning is not drawn to metal. The National Weather Service lists the idea as a myth and says height, shape and isolation decide where lightning strikes (NWS lightning myths).
Energy claims deserve care too. We do not quote savings percentages, because we have no reliable source for them, and no federal tax credit applies to either roof in 2026.

Questions
Metal roof vs shingles: common questions
Is a metal roof worth it compared with shingles?
If you plan to stay a long time, often yes: InterNACHI estimates 40 to 80 years for metal roofing and about 30 for architectural shingles. If you may sell within a few years, shingles usually cost less overall.
How much more does metal cost than shingles?
Nationally, HomeGuide puts standing seam at $9 to $16 per square foot installed and asphalt at $3 to $6, so metal typically costs two to three times as much up front. Your exact price comes from a free measurement.
Is a metal roof louder than shingles in the rain?
The Metal Roofing Alliance says there is little difference when metal is installed over solid decking with insulation. We do not promise a silent roof.
Do metal roofs attract lightning?
No. The National Weather Service says the presence of metal makes no difference to where lightning strikes; height, shape and isolation are what matter.
Which is lighter, metal or shingles?
Metal. Figures from Classic Metal Roofing Systems put steel roofing at 80 to 125 pounds per 100 square feet, against 275 to 425 pounds for asphalt shingles.
Does either roof qualify for a federal tax credit?
No. The IRS says metal and asphalt roofs stopped qualifying, and the 25C credit itself ended for property placed in service after December 31, 2025.
Can a metal roof go over my existing shingles?
Only over one sound layer of asphalt on a sound deck, under New Jersey’s tear-off rule, and only if the panel maker allows it. Two or more layers must come off.
