Metal costs roughly two to three times what architectural asphalt costs and lasts roughly two to three times as long. Almost every honest version of this comparison ends up there. The interesting question is not which material is better, it is which one is better for how long you actually plan to own the building.
Nobody has ever asked us this question casually. It arrives when a roof is already failing and there is a number attached to the answer.
What each one actually costs
Installed pricing swings hard with pitch, complexity, tear-off, decking condition and what the metal market did that quarter. Treat the shape of this as reliable and the exact figures as something to confirm on your own roof.
| Architectural asphalt | Exposed-fastener metal | Standing seam metal | |
|---|---|---|---|
| Relative installed cost | Baseline | ~1.5–2x | ~2.5–3.5x |
| Typical rated life | 25–30 yrs | 25–40 yrs | 40–70 yrs |
| Fasteners | Nails, concealed | Screws through the face | Clips, concealed |
| Main failure mode | Granule loss, mat bruising | Gasket and screw backing out | Panel oil-canning, flashing details |
| Re-roof labor | Straightforward | Straightforward | Specialized |
| Salvage at end of life | Landfill | Recyclable | Recyclable |
The line that matters most in that table is the fastener row. An exposed-fastener metal roof is a roof with several thousand rubber washers on it, and rubber washers have a shorter clock than steel. Budget a fastener walk every seven to ten years or the cheap metal roof becomes the expensive one.
Where metal genuinely wins
Long ownership. If you hold the building for 30 years you buy one metal roof or two asphalt roofs, and the second asphalt roof is priced in future dollars with future labor rates.
Low-slope and complex water paths. Standing seam handles slopes that asphalt is not rated for. NRCA and the shingle manufacturers both draw a hard line at 2:12 for asphalt, with doubled underlayment between 2:12 and 4:12. Below that, asphalt is not a debate, it is a code violation.
Wildfire exposure. Metal is non-combustible. In a wildland interface zone that is not a preference, it is often what the insurer wants to see.
Heat. A light-colored coated metal panel reflects a large share of solar gain instead of storing it. In a cooling-dominated climate that shows up on the utility bill, and it shows up in attic temperature, which is what actually cooks a roof from underneath.
Where asphalt is the right call and we will say so
Most of the time, honestly. Asphalt is the default for a reason and the reasons are good ones.
You are selling inside ten years. A new architectural asphalt roof is a fully effective selling point on a listing. Buyers read "new roof" and stop reading. You will not recover a metal premium at closing.
The roof is complicated and the budget is not large. Every valley, dormer, saddle and pipe on a metal roof is a hand-formed flashing detail priced by a skilled installer. On asphalt those same details are routine. Complexity inflates a metal bid much faster than it inflates an asphalt one.
Hail is your main threat and you want a claim to be simple. Impact-resistant Class 4 asphalt often earns a premium credit, replaces cleanly after a storm, and does not leave you arguing about whether dents are cosmetic. Metal dents and the dents are frequently ruled cosmetic. Ask us about Class 4 before you assume you need metal.
You have an HOA. Some architectural committees still treat residential metal as an agricultural look. Check before you fall in love with a panel profile.
The three myths worth killing
Noise. A residential metal roof sits on plywood decking over underlayment, and it is not measurably louder inside than asphalt. The loud roofs everyone remembers are corrugated panels screwed to open purlins over a barn or a carport, with nothing but air behind them.
Lightning. Height and geometry attract lightning, not metal. Metal spreads the energy across a wide conductive surface and does not burn. Insurers do not surcharge for it.
Heat. People assume a metal roof bakes the house because a metal slide burns your legs in July. Radiant reflectivity is what governs a roof assembly, and coated metal reflects better than a dark asphalt shingle does. The slide is not a roof.
The parts of the bid that decide the outcome
Both materials fail at the same places, and neither material saves a bad installation.
Ventilation. Intake at the soffit and exhaust at the ridge, balanced, with the intake not stuffed with insulation. A shingle roof over a dead attic cooks its mat from below and loses years off its rating. Our roof ventilation work exists because this is the most commonly skipped item on the entire job.
Underlayment. Synthetic over felt is now standard. Ice-and-water membrane at eaves, valleys and penetrations is worth paying for in any climate that freezes.
Flashing. Sidewall, chimney, valley and pipe. If a bid does not itemize new flashing, it is reusing the old flashing, and old flashing is where the next leak comes from.
Decking. Insist on a line item for replacing deteriorated sheathing at a stated per-sheet price. Every roof has some. A bid that pretends otherwise will produce a change order on day two.
The decision, compressed
Ask yourself one question: how many more years will you own this building? Under ten, buy good architectural asphalt and spend the difference on ventilation, flashing and a longer workmanship warranty. Over twenty, and especially with a simple roof shape, metal is very likely the cheaper roof measured across the time you own it. Between ten and twenty is a genuine toss-up that comes down to slope, complexity and whether you like the look.
One opinion, no hedging: never buy exposed-fastener metal for a house you intend to keep and ignore. It is a fine, economical roof for a shop, a barn or a porch. On a residence it is a maintenance schedule disguised as a permanent roof, and the people who are unhappy with metal roofing five years later almost always bought that one.
Bottom line
Metal is not better than asphalt. It is a different purchase with a different time horizon, and the price gap narrows the longer you stay. Get both bids on the same roof with the same ventilation, underlayment and flashing scope so you are comparing materials rather than comparing two different levels of care.

- Roof Replacement →
A replacement in Lakewood is won or lost at the details, not on the shingle wrapper. A south slope here can sit above freezing on a January afternoon and drop back below it by dark, and every flashing, boot and sealant joint pays for that swing.
- Asphalt Shingle Roofs →
Asphalt shingles are the right covering for the large majority of Lakewood homes, and the interesting question is not which brand. It is whether the installation respects a climate that heats a slope hard and freezes it the same night.
- Metal Roofing →
Metal is the covering that most rewards a climate like ours, and also the one where the wrong version disappoints fastest. The difference is whether the roof depends on a hole in a panel to stay watertight.
- Roof Leak Repair →
Most Lakewood roof leaks are not holes. They are joints that used to be tight.

Frequently asked questions
Is a metal roof worth the extra cost over shingles?
It depends almost entirely on how long you plan to own the house. Metal typically costs two to three times what architectural asphalt costs and lasts two to three times as long, so the cost per year of service is roughly comparable. If you sell in seven years you pay the premium and hand the back half of the lifespan to somebody else. If this is the house you retire in, metal is very likely the cheaper roof.
Do metal roofs make more noise in the rain?
A metal roof installed over solid decking with underlayment is not meaningfully louder than asphalt inside the house. The noise reputation comes from barns and porch covers, where corrugated panels are screwed to open purlins with nothing but air behind them. That assembly is genuinely loud. A residential roof over plywood is not the same thing.
Does a metal roof attract lightning?
No. Lightning is not attracted by metal, it is attracted by height and geometry. What metal does is conduct the energy safely across a broad surface rather than concentrating it, and metal is non-combustible, so if your house is struck a metal roof is the better outcome, not the worse one. Insurers do not rate it as a hazard.
How long does a metal roof last compared to shingles?
Manufacturers generally rate architectural asphalt shingles at 25 to 30 years and quality standing seam steel or aluminum at 40 to 70 years. Real-world numbers are lower for both in a harsh climate. The controlling variable for metal is usually the fastener and sealant schedule on an exposed-fastener system, not the panel itself, which is why concealed-fastener standing seam ages better.
Can you install metal roofing over existing shingles?
It is sometimes allowed and it is sometimes a bad idea. Some jurisdictions permit one metal layer over one shingle layer, often with a batten or slip sheet, and it saves real money on tear-off and disposal. What it also does is hide the condition of the decking, which is the single thing you most want to look at during a re-roof. Ask for a decking inspection either way.
Which is better for hail, metal or asphalt?
Metal generally survives hail structurally while showing cosmetic dents, and asphalt generally survives it cosmetically until the mat bruises and then it leaks. Impact-resistant Class 4 asphalt closes much of that gap and often earns an insurance discount. If hail is a routine event where you live, ask specifically about Class 4 asphalt before assuming metal is the only answer.

Every article here is written from roofing work done in Lakewood and the west Denver metro, so the numbers reflect local labour, permit and material costs rather than a national average. Your own job can land either side of them depending on access, the condition of what is already there, and the materials you pick — counterflashing cut into a mortar reglet, lead pipe-boot flashings with fastened storm collars, ASTM C920 Class 50 polyurethane joint sealant.
