Book My Free Inspection →The expensive part of asphalt is buying it twice
A metal roof costs more on day one. Here's what the cheaper roof actually costs over the life of your house — typical DMV ranges.
You buy the same roof 2–3 times
Asphalt lasts 15–20 years in the DMV freeze-thaw. Stay in your home long enough and you'll pay for a second tear-off — at future prices, with future disruption.
Second asphalt roof: $12,000–$22,000 moreHail totals asphalt roofs
The hail that bruises shingles into an insurance claim usually just glances off metal. Fewer claims means fewer deductibles — and fewer premium hikes.
Each storm claim: $1,000–$2,500 deductible + rate riskDark shingles cook your attic
Asphalt absorbs summer heat and radiates it into the attic all evening. Reflective Kynar-finish metal sends it back at the sky instead.
Typical cooling savings with cool-roof metal: 10–25%Cheap metal is a false economy
Bargain screw-down installs with unplugged fastener plans start leaking at year 10–15 as gaskets age and screws back out — then you pay for chasing leaks across the whole field.
Fastener & leak remediation: $2,000–$6,000Typical ranges, not quotes. The free inspection prices metal and asphalt side by side for your roof, in writing.
What metal buys you over asphalt
2-3x the lifespan
Asphalt runs 15–20 years in the DMV's freeze-thaw cycles. Properly installed standing seam runs 40-70. You buy one roof instead of three.
Storm resilience
Metal sheds hail that bruises asphalt and holds seam integrity in winds that strip shingles. Insurance carriers know it — some offer premium credits for impact-rated metal roofs.
Energy savings
Reflective Kynar finishes cut summer attic temperatures and cooling bills — a real number in Maryland's humid summers — and many panels qualify as cool roofs.
Standing seam vs. screw-down
Standing seam
Concealed-fastener panels with raised, interlocking seams — no exposed screws to back out and leak. The premium residential choice, with clean lines and the longest service life. Available in snap-lock and mechanically-seamed profiles.
Exposed-fastener (screw-down)
Ribbed panels fastened through the face — a lower-cost metal option well suited to outbuildings, barns, and some low-slope sections, installed with proper gasketed fasteners and a fastener-replacement plan.
Substrate done right
Whichever panel, the roof is only as good as what's under it. We typically tear off to inspect and repair decking, lay a high-temp underlayment, and detail every valley, penetration, and transition before a panel goes down.
| Architectural asphalt | Screw-down metal (26–29 ga) | Metal shingle / stone-coated | Standing seam (24 ga, Kynar 500) | |
|---|---|---|---|---|
| Relative cost | Baseline | About 1.4× asphalt | About 1.8× asphalt | About 2.4× asphalt |
| Expected life | 15–25 years | 30–45 years | 40–60 years | 40–70 years |
| Fasteners | Nails under shingles | Exposed, gasketed — re-torque over time | Concealed — interlocking panels | Concealed clips — nothing exposed to weather |
| 40-year cost of ownership | Two full roofs, at today’s price and again at tomorrow’s | One roof + fastener maintenance | One roof, minimal maintenance | One roof, near-zero maintenance |
| Best for | Budget-first, shorter horizon | Outbuildings, barns, budget metal | Metal lifespan that still reads as shingle or slate from the curb — HOA-friendly | Forever homes — the last roof you buy |
*Typical DMV ranges for an average single-family roof. $0-down financing spreads standing seam into a predictable monthly payment — your free inspection produces exact numbers.

From side-by-side math to a seamed, swept roof
A metal roof is a precision job — panels cut to your roof, details done once, correctly. Here's the sequence, first call to registered warranty.
Inspection with metal and asphalt priced side by side
A specialist measures the roof, documents its condition with dated photos, and prices standing seam against architectural asphalt for your home — so the 40-year math is real numbers, not brochure talk. If metal isn't right for your roof, that goes in writing too.
Day 1 · FreeProfile, gauge & finish selection
Snap-lock or mechanically-seamed standing seam, metal shingle, or screw-down for outbuildings — in 24-gauge steel with Kynar 500 finishes that hold color for decades. $0-down financing from 12 to 180 months (on approved credit) spreads a forever roof into a monthly payment.
Your call, real samplesTear-off & substrate prep
We strip to the deck, repair any soft decking, lay high-temp underlayment, and detail every valley, penetration, and transition — the parts that decide whether a 70-year panel actually gets to live 70 years.
The part that mattersPanels formed, hung & seamed
Panels are cut to your roof's exact lengths, clipped down with concealed fasteners, and seamed — no exposed screws to back out and leak on a standing-seam field. Flashing and ridge details finish in matching Kynar stock.
Install daysMagnet sweep, walkthrough & warranty
Metal offcuts and fasteners are magnet-swept from lawn and beds, you walk the finished roof with the project manager, and the manufacturer's finish/substrate warranty plus our 2-year workmanship warranty go in writing.

Family-owned and operating across Maryland since 2005. Every contract carries our license numbers, every crew is GAF Certified, and every job is backed in writing.
Even a 70-year roof deserves a 10-minute checkup
Metal wins on lifespan because there's almost nothing to fail — but sealants at penetrations and fasteners on older screw-down roofs still age. An annual inspection catches those small items while they're service calls, and if you're still on asphalt, it tells you honestly how many years you have left to plan the upgrade. It's a $400 service, free — and the dated photo report is yours either way.
Book My Free Inspection →Straight answers
Is a metal roof louder in rain?
No — over solid decking and underlayment, a metal roof is no louder than asphalt. The rain-on-a-barn sound comes from open-frame structures.
Can you install metal over my existing shingles?
Sometimes, but we usually recommend tear-off so decking issues get found and fixed — that's what protects the 40-70 year lifespan.
Does metal cost more?
Upfront, yes — typically 2-3x asphalt. Over the roof's life it's usually cheaper per year, and it adds resale value.
Standing seam or screw-down?
Standing seam hides its fasteners and is the premium residential choice; exposed-fastener screw-down panels cost less and suit outbuildings and some low-slope sections. We recommend based on your roof, not our margin.
What gauge and finish do you install?
Residential standing seam is 24-gauge steel standard with Kynar 500 (PVDF) finishes — the coating that holds color for decades instead of chalking. Screw-down panels for outbuildings run 26–29 gauge with gasketed fasteners and a written fastener-maintenance plan.
How much does a metal roof cost in Montgomery County?
Standing seam runs roughly two and a half times architectural asphalt on the same roof, and metal shingle a little under twice. Roof size, pitch, and detail work move the number, which is why we quote from measurements, not square-footage folklore — our Bethesda cost guide shows how local pricing breaks down, our Montgomery County metal roofing page publishes the per-square price-book rates, and the free inspection produces your exact figure in writing.
Can I finance a metal roof with $0 down?
Yes — and metal is where long financing terms earn their keep: $0 down across 12 to 180 months (on approved credit) on a roof that outlasts the loan by decades. Details on the financing page; the pre-check takes minutes during your inspection.
Does hail total a metal roof the way it does asphalt?
Rarely. Hail that bruises asphalt into an insurance claim usually just glances off 24-gauge steel — cosmetic dings at worst. If a storm already hit your current asphalt roof, that's a different conversation: get it documented through storm restoration first, because some homeowners put claim proceeds toward upgrading to metal, paying only the difference plus deductible.
