How much does a roof replacement cost in Maryland?
The short answer for 2026: most full asphalt-shingle roof replacements in Maryland cost $4.35 to $8.75 per square foot installed — roughly $11,000 to $28,000 for a typical single-family home. Townhomes and small ramblers can come in under $10,000; large colonials with steep or cut-up rooflines, and any standing-seam metal roof, run well above the midpoint. Below is the honest county-by-county breakdown, what actually moves the number, and the one scenario where your cost shrinks to just your insurance deductible.

Cost by county — where your total lands
Per-square-foot pricing is fairly consistent across the state. What moves the total is the housing stock: bigger houses, steeper pitches and more complex rooflines mean more squares and more labor. Here is how the six counties we work in every week compare:
| County | Typical replacement total (2026) | Why |
|---|---|---|
| Montgomery | $13,000–$32,000 | Large colonials and customs in Bethesda, Potomac and Chevy Chase carry the state's biggest roofs; county permit fees and labor run high. Full Montgomery County guide → |
| Howard | $12,000–$30,000 | Columbia and Ellicott City skew large and cut-up; Columbia Association villages add design review. Columbia guide → |
| Anne Arundel | $11,000–$26,000 | Mix of waterfront customs near Annapolis and modest mid-century stock in Glen Burnie; bay-exposure wind ratings matter here. Annapolis guide → |
| Prince George's | $10,000–$22,000 | Large share of 1960s–80s ramblers, split-levels and Levitt-built colonials with simpler rooflines — totals land below the DC-side counties. Bowie guide → |
| Frederick | $10,000–$24,000 | Newer subdivisions price efficiently; historic downtown Frederick and farmhouses with metal or slate cost more. Frederick guide → |
| Carroll | $10,000–$23,000 | Simpler rooflines and lower labor overhead than the Washington suburbs; long rural driveways occasionally add logistics cost. Westminster guide → |
What actually drives the price in Maryland
- Roof size and pitch. Roofers price by the "square" (100 sq ft of roof surface). A walkable 4/12 rambler roof and a 12/12 colonial with dormers can sit on the same footprint and differ by $8,000, because steep work is slower and needs more safety rigging.
- Tear-off findings. Many Maryland homes built before the mid-1970s have plank decking that needs plywood over-boarding, and some hide a second shingle layer. Both are real line items that only appear at tear-off — a written scope should say up front what they'd cost if found.
- Material tier. The spread between builder-grade 3-tab and a designer shingle is roughly 2× on materials; metal is 2–3× the installed cost of architectural shingle but can be the last roof the house ever needs.
- County permits. Most Maryland counties require a permit for a residential re-roof; fees run roughly $100–$400 depending on the county, and your contractor — not you — should pull it.
- Code items that didn't exist when your roof was installed. Current Maryland code requires ice-and-water barrier at eaves and valleys, drip edge, and proper attic ventilation. If your last roof predates these, expect them in a compliant quote — and be suspicious of any quote that omits them.
Rule of thumb: take your home's footprint, add roughly 10–30% for pitch and overhangs, and multiply by $4.35–$8.75. For an exact measurement in 60 seconds, use our instant satellite roof quote.
The insurance scenario: when the storm pays for the roof
Maryland sits in a real hail and wind corridor — NOAA has logged hundreds of severe wind and hail reports across Montgomery, Frederick, Howard, Anne Arundel, Prince George's and Carroll counties in the last six months alone. If a covered storm damaged your roof, your homeowners policy typically pays for the replacement, and on an approved claim your deductible is typically your only out-of-pocket cost.
Three things Maryland homeowners should know before filing:
- Insurers cover sudden storm damage, not age. The damage has to be documented with photos and tied to a specific storm date. Our live storm tracker plots real NOAA reports by neighborhood so you can check whether your street was hit.
- You file and own the claim. A reputable contractor documents the damage and meets your adjuster — but never "handles the claim for you" or asks you to sign over benefits.
- Deductible "help" is illegal. In Maryland it is against the law for a contractor to pay, waive or rebate your insurance deductible. Anyone offering a "free roof" with no deductible is describing insurance fraud. Walk away.

A licensed inspector documents your whole roof and you keep the report either way. If your roof doesn't need work, we'll tell you that too. No pressure, no sales script.

- Check the storm path first. An approved claim turns a $15,000 project into a deductible-sized expense.
- Get the measurement, not a guess. Quotes based on a drive-by or your floor area are wrong in both directions; per-square pricing off a real measurement is the only honest baseline.
- Don't overlay. A second shingle layer looks cheaper today but voids most manufacturer warranties, hides deck rot, and costs more at the next replacement.
- Use financing instead of downgrading materials. $0-down plans on approved credit with terms from 12 to 180 months are available through third-party lenders — run your numbers on the financing calculator.
- Verify the MHIC license. Maryland law requires home-improvement contractors to hold an MHIC license — verify any contractor free at the Maryland Department of Labor's MHIC search before signing. Our contractor checklist covers the rest of the red flags.

Frequently asked questions
How much does a roof replacement cost in Maryland?
In 2026, most full architectural-shingle replacements in Maryland run $4.35–$8.75 per square foot installed — roughly $11,000 to $28,000 for a typical single-family home. Townhomes can come in under $10,000; large or steep roofs and metal systems run higher. The exact number follows a free on-site measurement.
Which Maryland counties are the most expensive for a new roof?
Montgomery and Howard counties usually top the state — homes are larger, rooflines more complex, and permits and labor cost more. Prince George's, Anne Arundel, Frederick and Carroll land toward the middle. Per-square-foot pricing is similar statewide; the total moves with roof size and complexity.
Does homeowners insurance ever pay for a roof replacement in Maryland?
Yes — when the roof was damaged by a covered peril such as hail or high wind. On an approved claim the insurer pays for the replacement and your deductible is typically your only out-of-pocket cost. Age and wear are never covered, and Maryland law makes it illegal for a contractor to pay or waive your deductible.
Do I need a permit to replace a roof in Maryland?
In most Maryland counties, yes — fees run roughly $100–$400 and the process varies by county. Your contractor should pull the permit and must hold a Maryland MHIC license, which you can verify free on the state's MHIC search. United Developers is MHIC #111971.
How long does a roof replacement take in Maryland?
Most single-family asphalt-shingle replacements finish in one day, weather permitting. Large, steep or slate/metal projects can take two to five days, and permitting adds a few days to two weeks up front depending on the county.
