Roof Replacement Cost in Maryland (2027 Price Guide)
Not your house? Change the size or pitch in Maryland
Pick the pitch that matches your roof - the rise over a twelve-inch run. From 9/12 up, crews tie off and work slower, and the price climbs. The Maryland default here is 5/12.
In Maryland, a typical 2,200 sq. ft. single-story house needs about $11,340 to $17,290 for a new asphalt shingle roof, old shingles off and hauled away. The job we priced has 24.9 squares of roofing (2,486 sq. ft.) on a 5/12 slope; removing one existing layer, labor and materials are all counted.
On a per-square basis (a square equals a hundred square feet), Maryland prices this roof at about $556.20. The same roof in architectural 50-year shingles is $12,610 to $19,210. Metal begins with steel shingles at roughly $24,400.

| Flat / low-slope membranes (priced on the 2,200 sq. ft. footprint) | |||
| EPDM rubber membrane | $16,750 to $21,760 | $19,260 | $875.11 |
| TPO membrane, 60-mil | $14,420 to $18,730 | $16,570 | $753.17 |
| PVC membrane, 60-mil | $17,440 to $22,650 | $20,040 | $910.75 |
Shingle rows use the same math as our roof replacement calculator; metal rows follow the metal roof calculator, and membranes follow the flat roof calculator. All of them carry the South Atlantic cost adjustment, which puts shingles and metal 6% below the U.S. average.
Price per Year of Roof
The real cost of a roof is price divided by the years it lasts. Hover a bar: metal costs more up front and less per year.
Service lives follow the climate-bell model above (asphalt peaks in moderate regions; metal assumes correct installation); prices are the Maryland estimates above.
The Line Items Behind a Maryland Roofing Bid
Line items, not markup, explain most bid gaps. Priced on the 24.9-square roof in this guide:
- Removal. Stripping one layer is worth about $3,320 here. Ask the roofer to confirm the layer count up front; a second one adds about $2,150.
- Hips and valleys. Take a basic gable as the baseline. A hip layout costs roughly $1,370 above it; dormers and valleys scattered across the roof cost about $2,310 above it.
- Access. Raise this roof a story and expect about $980 on top of the price, for staging, hauling and slower work.
- Skylights. Swapping or adding a skylight costs around $340 each at Maryland rates.
- Sheathing repairs. Soft spots in the roof deck show up during tear-off. A per-sheet price in the contract keeps that from becoming an open-ended charge.
- Flashing and ventilation. Reusing old flashing saves a little now and causes leaks later. Gutters are a separate trade line; the gutter cost calculator covers them.
- Permit, dumpster, cleanup. Each town sets its own fees. Get them written into the price, along with a magnetic nail sweep of the yard.

Figures cover the 5/12 roof above (2,486 sq. ft.) at Maryland prices; add gutters, skylights and any deck repairs separately.
Compare scope first and price second. A bid that skips new flashing or a decking allowance only looks cheaper.
How Maryland Weather Ages a Roof
Averages for Maryland: summer highs around 88°F, winter highs around 43°F, winter lows around 25°F. The map below files it under Region 3. What that means for materials and installation in Maryland:
Thaw damage. Meltwater that refreezes in gutters and seams expands and opens them a little more each time. Keep gutters clear and have every flashing joint redone during the re-roof.
Humidity. Damp, warm air grows algae and mildew on shady roof planes. Choose algae-resistant shingles and keep branches trimmed back so the roof dries after rain.
Salt air. Near the ocean, salt corrodes steel fasteners, flashing and cut metal edges. Ask for corrosion-resistant nails and flashing, and choose aluminum or coastal-rated metal panels.
Row houses and attached homes often have flat roofs, so the membrane prices below matter as much as the shingle prices.
Where Shingles Live Longest: the Climate Bell
Asphalt life peaks in the moderate middle (Region 3) and falls toward BOTH ends of the map above - cold regions destroy shingles with ice dams, hot ones bake them. Note the middle columns: shingles marketed as “lifetime” are good for about 25 real-world years at best - Maryland is Region 3. Hover any column.
low pitch holds snow and ice - it costs the most years in cold regions
Planning figures from our climate model, for ventilation-correct installs - a baked, unvented attic can take years off any column. Pitch adjusts the asphalt columns only; metal sheds snow at any sane pitch.

Pricing a Metal Roof in Maryland
Metal is not one product. Long panels, metal shingles, stone-coated tiles and copper each solve a different problem, and the price gap between them is wide.
- Standing seam: $32,530 to $49,580. Long panels run from ridge to eave and lock together at raised seams, with the clips hidden underneath. No screws go through the face, so there are far fewer places for a leak to start. On this roof it runs about $24,300 more than architectural shingles.
- Steel shingles: $24,400 to $37,200. Aluminum shingles: $26,980 to $41,130. The look of a regular roof with the life of metal. These pieces work on steep or complicated roofs. Steel resists dents; aluminum resists corrosion.
- Stone-coated steel: $33,220 to $50,630. Steel panels covered in crushed stone and shaped like clay tile or wood shake. The texture hides hail marks and softens rain noise.
- Copper: custom quote only. Copper sits above every other metal in price and is bid job by job, so it has no line in our calculator. It is the roof of old churches and city landmarks. On a house it makes the most sense on a small, visible spot or a historic home.
Ice dams are the bigger risk, and metal stops most of them by shedding snow before it can refreeze. A reflective finish then helps through the hot weeks; copper weathers dark and does not.
Coastal homes should look at aluminum panels or coastal-warranted steel, with matching corrosion-resistant fasteners. Owners who stay put get the most from metal, because the long service life is where the savings sit. The metal roof calculator prices each panel style separately.

Roofing Season in Maryland
There is no long off-season here. Spring and fall bring the easiest working weather, and scheduling early beats storm-season backlogs.
Pricing Low-Slope Roofs in Maryland
Low-slope sections need a sealed membrane instead of shingles. Priced across the whole 2,200 sq. ft. footprint, a membrane roof in Maryland costs:
- EPDM rubber: $16,750 to $21,760. Think of a heavy inner tube spread over the deck. The seams are glued, not welded, and over time they are its weak spot. It earns its place on small, simple roofs and in cold places.
- TPO, 60-mil: $14,420 to $18,730. A white single-ply sheet whose seams are welded with hot air into one piece. It reflects the sun and now covers most new flat roofs on homes and shops.
- PVC, 60-mil: $17,440 to $22,650. Also white and heat-welded, but tougher against grease, chemicals and standing water. It is the pick for roof decks, low spots that hold puddles, and anything near a kitchen exhaust.
Ranked by price for this home, TPO is cheapest, EPDM is next, and PVC costs the most. Tear-off of one existing layer and new polyiso board are part of each figure. A small section will price higher per square foot. Ponding water is the main enemy of flat roofs through a Maryland winter. Ask for tapered insulation at low spots and clear drains. For thicker insulation or a different membrane, use the flat roof calculator.
Winter does the most damage here, so seams and drainage come first. If the flat roof sits over living space, white TPO or PVC also helps in summer, when highs reach 88°F.
Maryland Roofing Costs by City
Contractors working in Baltimore, Columbia and Germantown pay more for crews, coverage and permits, so their bids land above the statewide figure; small towns usually come in lower. Same 30-year shingle roof, by city:

Answers for Maryland Homeowners
What does a roof square mean on a quote?
A square is a hundred square feet of roof surface. For this 2,200 sq. ft. footprint at a 5/12 pitch, figure about 24.9 squares (2,486 sq. ft.). Use the same number when you compare bids.
Is a roofing permit required in Maryland?
Most local building departments want one when the old roof comes off completely, and some send an inspector at the end. The contractor should file it; be cautious if a roofer asks you to.
Is an old roof covered by my insurer?
Only for sudden damage such as wind, hail or a falling tree, never for plain wear. Certain policies cover an aging roof at its depreciated worth rather than full replacement. On a roof that costs $11,340 to $17,290 to replace, that gap is large, so check your settlement terms.
What is the usual timeline for a re-roof?
Plan on a few days at most for an asphalt roof around 2,486 sq. ft. Complex shapes, a second layer or bad weather can stretch it.
