Cost Difference: Brooklyn Metal vs Asphalt Roofing

Sticker shock is real when you first see what a standing seam metal roof costs compared to asphalt shingles, and I’m not gonna sugarcoat that first number. In Brooklyn right now, metal roofing typically runs between $18 and $28 per square foot installed, while architectural asphalt shingles land in the $8 to $13 range for a complete tear-off and re-roof. On a typical 1,200-square-foot Brooklyn rowhouse roof, that’s about $9,600 to $15,600 for asphalt versus $21,600 to $33,600 for metal-a gap big enough to make most folks reach for the cheaper option and call it a day.

Here’s the thing, though: when I lay out those numbers on someone’s kitchen table, I never stop at the check they’ll write this summer. I flip the page and show them cost per year over the life of the roof, because that’s when metal stops looking expensive and asphalt starts looking pretty wasteful. A quality metal roof in Brooklyn typically lasts 40 to 50 years with almost no maintenance. An asphalt roof? You’re looking at 18 to 25 years if you’re lucky, and maybe only 12 to 15 if your attic ventilation isn’t great or you’ve got dark shingles baking under the summer sun.

So let’s do quick math on that 1,200-square-foot roof: if you pay $12,000 for asphalt and replace it once after 20 years (another $14,000 adjusted for inflation), you’ve spent $26,000 over 40 years-more than the metal roof you could’ve installed for $24,000 once and been done. That asphalt roof costs you roughly $650 per year of protection. The metal? About $600 per year, and it’ll still be standing strong when your kid inherits the place. Around Bay Ridge, Bensonhest, and Park Slope, where folks plan to stay put or pass these homes down, that math starts to make a whole lot of sense.

Metal Costs More Now, But What About Twice?

The real cost trap isn’t the metal roof’s price tag-it’s the fact that you’re probably gonna pay for two asphalt roofs during the same stretch one metal roof covers. If you’re planning to stay in your Brooklyn place for more than ten years, do you really care what’s cheapest for the next five? Because that second asphalt replacement is coming, and it’s gonna hurt worse than the first one thanks to labor inflation and rising material costs.

I’ve watched this play out over and over in Crown Heights and Bushwick. Somebody chooses asphalt in 2005, thinking they saved $12,000. By 2023 they’re re-roofing again, only now that same job costs $16,000 instead of the $10,000 it would’ve been back then. Meanwhile, their neighbor who bit the bullet and went metal in 2005 has done literally nothing except maybe rinse some leaves off during a gutter cleaning. No patches, no emergency leak calls during a February ice storm, no second mortgage-sized invoice.

Honestly, metal is almost always more expensive on day one-and that’s exactly why it can end up cheaper. Once you factor in replacement cycles, repair costs, and the way asphalt shingles tend to fail right when you least expect it (or can least afford it), the metal roof starts looking like the financially responsible choice, not the splurge.

What “Installed Cost” Actually Includes in Brooklyn

Before we go further, let’s be clear about what those price ranges cover, because nobody wants surprise charges once the crew shows up. A proper installed cost in Brooklyn includes complete tear-off of your old roof down to the deck, disposal and dump fees (which aren’t cheap in the city), any deck repairs or sheathing replacement if we find rot or soft spots, new underlayment, the roofing material itself, all flashing and trim work, permits and inspection fees, and labor. If a quote you’re getting doesn’t spell that out, ask. I’ve seen too many “low-ball” asphalt bids that skip the permit or assume your deck is perfect-then you get change orders that erase any savings.

How Brooklyn’s Weather Changes the Real Cost

On a narrow block in Bay Ridge last winter, I watched two nearly identical roofs age in completely different ways, and the difference came down to material choice and a couple brutal Brooklyn summers in between. One house had standard gray asphalt shingles installed in 2012; the other went with a light-colored standing seam metal roof the same year. By 2023, the asphalt roof was shedding granules, had three patched spots from ice dam leaks, and was starting to curl along the south-facing slope. The metal roof looked brand new-no rust, no dents, nothing.

During a humid July in Bushwick a few years back, I got called to a three-family where the asphalt shingles were curling and shedding granules after only eleven years because of poor attic ventilation and dark shingles baking in the sun, and the top-floor tenants were running window AC units basically nonstop just to keep the apartment under 80 degrees. Instead of just re-roofing with more asphalt, I walked the owner through how a lighter-colored metal roof with proper underlayment would drop the top-floor summer temps by six to eight degrees, trim their electric bills, keep tenants happier, and last three times as long even in that brutal heat. The upfront cost was higher-about $9,000 more for the whole building-but when we added up the cooling savings (roughly $400 per summer), the avoided second re-roof (another $15,000 in 15 years), and zero repair calls, the metal option actually saved the owner about $11,000 over 30 years. That’s the kind of number that makes someone pull the trigger.

Brooklyn’s freeze-thaw cycles are vicious on asphalt. Ice dams form along the eaves when your attic’s too warm, meltwater backs up under the shingles, and suddenly you’ve got a drip in the dining room ceiling in the middle of February. Metal roofs shed snow and ice way better because the surface is slick and the seams are raised, so water runs off instead of pooling. That means fewer emergency calls, less interior damage, and no $800 patch jobs every couple winters.

Two Roofs, One Block: A Real-World Aging Comparison

Let me zoom in on one specific example from a Carroll Gardens block I know pretty well. Two brownstones, built the same year, same size, same southern exposure. In 2010, one owner re-roofed with high-end architectural asphalt shingles for about $11,500. The other owner-actually a couple renovating under landmark rules-chose a charcoal standing seam metal roof that cost $23,000 after we worked with the preservation board on profile and color. Fast-forward to 2024: the asphalt roof has been patched twice, lost a bunch of shingles during Hurricane Sandy’s aftermath, and is now at end-of-life and needs replacement again-call it another $17,000 today. Total spend over 14 years: $28,500, and they’re not done. The metal roof? They’ve spent $23,000 total, it still looks sharp, and it’ll easily go another 30 years. That’s $2,036 per year for the asphalt owner so far, versus $1,643 per year for metal-and the gap only gets wider as time rolls on.

Running Your Own Cost-Per-Year Numbers

A Park Slope owner said to me last fall, “Ramon, just tell me which roof hurts my wallet the least over time.” So we sat down with a notepad and worked through his actual numbers, and I’m gonna walk you through the same process because it’s simple enough to do at your own kitchen table before you ever call a contractor.

Napkin Math for a 1,200 sq ft Brooklyn Rowhouse (2024 dollars):
Asphalt Option: Install cost $12,000 ÷ 20-year lifespan = $600/year base cost. Add $150/year average for repairs, patches, and ice dam fixes. Add $200/year extra cooling cost because of heat absorption. Total = $950 per year. Then in year 21, you pay another $16,000 (inflation-adjusted) to do it all again.
Metal Option: Install cost $25,000 ÷ 45-year lifespan = $556/year base cost. Add $25/year for minimal maintenance (basically a rinse). Subtract $150/year cooling savings from reflective surface. Total = $431 per year, and you’re done for half a century.

That’s a $519 difference every single year in favor of metal once you account for repairs and energy, and it assumes the asphalt roof actually makes it to 20 years without a major failure. In my experience around Brooklyn, plenty of asphalt roofs start needing serious attention around year 12 or 15, especially on buildings with less-than-perfect ventilation or where someone skimped on underlayment the first time around. Every patch call and emergency tarp job chips away at that “savings” you thought you were getting.

Don’t forget to factor in your own plans, either. If you’re selling in five years, asphalt probably makes sense because you won’t be around to pay for the replacement, and a new roof-any new roof-looks good to buyers. But if you’re staying, or if you’re a landlord holding rental property long-term, or if you’re renovating a place you want to pass down to your kids, metal is pretty much always the smarter financial play once you run the real numbers instead of just looking at the invoice you’ll get this summer.

DIY Cost Estimating Without a Site Visit

You can get a ballpark sense of your own roof cost before you ever pick up the phone. Measure your roof’s footprint in square feet-easiest way is to use your property’s tax lot dimensions if it’s a flat or simple gable roof, or use Google Earth and a little geometry if it’s more complex. Multiply by 1.15 to account for slope and waste. Then use $10/sq ft as a rough Brooklyn asphalt number and $22/sq ft for metal. A 1,000-square-foot footprint becomes about 1,150 installed square feet, so figure $11,500 for asphalt or $25,300 for metal as a starting point. Add 10-15% if your roof is steeper than a typical Brooklyn rowhouse pitch or if you’ve got a lot of chimneys, skylights, and dormers that make the job fussier.

Cost Traps and Smart Money Moves

The biggest mistake I see Brooklyn homeowners make is choosing a roof based solely on what they can afford right this minute, without asking what that choice is gonna cost them over the next decade. Cheap asphalt installed by the lowest bidder might look like a win in June, but when you’re calling for emergency repairs during the next Nor’easter or dealing with a full replacement ten years early because the shingles were garbage quality, you’ve actually spent way more than if you’d stretched for mid-grade asphalt or even considered metal from the start.

Here’s an insider move: if metal’s upfront cost is just out of reach, ask your contractor about financing options or see if you can phase the work-do the main roof now and the garage or back extension next year. Metal Roof Masters and a lot of Brooklyn roofers work with financing companies that’ll spread a $25,000 job into manageable monthly payments, and when you look at it that way-maybe $380 a month over six years-it stops feeling impossible and starts feeling like a smart trade against what you’d be spending on repairs and early replacement with asphalt anyway. I watched a Bensonhurst owner last February make exactly that call. She’d been terrified of “metal sticker shock” and was ready to go asphalt, but when we sat down and laid out a side-by-side 30-year cost comparison on her kitchen table-showing how the cheaper shingles would actually cost more once you factored in a second replacement and constant ice-dam repairs during those brutal Brooklyn winters-she realized financing the metal roof made way more sense than paying cash for asphalt twice. That one decision turned into three referrals on the same block once her neighbors saw how clean the install looked and heard her talking about never worrying about her roof again.

Also, watch out for the “it’s good enough” trap with ventilation and underlayment. I’ve torn off plenty of asphalt roofs that failed early-we’re talking 11 or 12 years instead of 20-because the attic ventilation was inadequate or the roofer skipped the ice-and-water shield along the eaves to save fifty bucks. Those shortcuts don’t just cut lifespan; they turn your roof into a maintenance nightmare that nickel-and-dimes you to death. If you’re gonna do asphalt, do it right: synthetic underlayment, full ice barrier, proper ridge and soffit vents. If your contractor won’t include that stuff in the base bid, find someone who will.

One last thing about noise, because it comes up every single time someone’s thinking about metal: yes, metal roofs can be louder during heavy rain or hail if they’re installed directly over open rafters with no insulation. But on a typical Brooklyn rowhouse or multifamily, you’ve got an attic space, insulation, and ceiling below the roof deck, so you’re not gonna hear much of anything. I’ve done standing seam installs in Carroll Gardens where tenants on the top floor told me afterward they actually noticed less noise than with the old asphalt because we used quality underlayment with sound-dampening properties. It’s one of those myths that sounds true but rarely plays out in real life, especially in the city where ambient street noise drowns out a little rain patter anyway.

So here’s the bottom line, written out the way I’d tell you if we were sitting at your kitchen table right now: if you’re planning to stay in your Brooklyn home for at least another 15 years, or if you’re holding onto rental property long-term, metal roofing will almost certainly cost you less per year of protection, comfort, and peace of mind than asphalt will, even though you’re writing a bigger check up front. If you’re flipping the place in three years or if cash flow is so tight that the extra $10,000 or $15,000 just isn’t feasible right now, go with quality asphalt installed the right way-synthetic underlayment, proper ventilation, and a contractor who’ll pull permits and stand behind the work. Either way, the goal is the same: keep water out, keep your people comfortable, and don’t spend a dollar more than you have to over the life of the building. That’s what I’ve been doing for 19 years, from Sunset Park to Bay Ridge to Bushwick, and it’s the only way to think about roofing that actually makes sense when you’re the one signing the checks.
