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.

Our model puts a new asphalt roof in Baltimore, MD at $11,750 to $17,920, based on a typical 2,200 sq. ft. single-story house. 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.

Divide it out and the installed rate is $576.36 per square; a square is the hundred square feet roofers quote by. Thicker 50-year architectural shingles raise the job to $13,060 to $19,910, and the cheapest metal choice, steel shingles, begins near $25,290.

That is about $500 above the statewide figure of $11,350 to $17,290, a typical Baltimore premium for labor, permits and insurance. The Baltimore figures cover its 41 ZIP codes in the independent city of Baltimore, the independent city of Baltimore and Anne Arundel County.

What Pushes a Baltimore, MD Roof Quote Up or Down

Line items, not markup, explain most bid gaps. Priced on the 24.9-square roof in this guide:

  • Strip and haul. Expect roughly $3,440 of the bid for one layer off. Each extra layer underneath raises it again, by about $2,230 for the second.
  • Design. Simple gables are the cheapest to cover. Figure about $1,420 more for a hip roof, or about $2,400 more when dormers and valleys cut it up.
  • Stories. Put this roof on a two-story house and the bid rises by about $1,020 for the extra climbing, staging and hauling.
  • Openings. Plan near $350 per skylight that gets replaced or added while the roof is open.
  • 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.
  • Town fees. Building permits and container rental are local costs; check whether each bid includes them.

Weather, Wear and Your Maryland Roof

A roof in Maryland lives in Climate Region 3: about 88°F on a typical summer afternoon, about 43°F on a winter afternoon, and about 25°F on a winter night. What that means for materials and installation in Maryland:

U.S. climate regions map (1 cool to 5 hot)

Freeze-thaw cycles. Water that seeps into a cracked shingle or an open seam freezes at night and widens the gap. Over many winters, small openings become leaks. Ice barrier at the eaves is inexpensive protection.

Algae streaks. The dark stains on many roofs here are algae that thrive in humid air. Algae-resistant shingles, made with copper-treated granules, stay clean much longer.

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.

Many older attached homes have flat or nearly flat roofs, which take a membrane instead of shingles.

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.

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.

Metal Roofing Prices in Baltimore, MD

A metal roof on a typical 2,200 sq. ft. single-story house in Baltimore, MD starts at $25,290. The type you pick matters more than the brand, so here is how the main options differ.

  • Standing seam: $33,710 to $51,380. The panels interlock at upright seams, and the clips let the metal grow and shrink with the weather. Budget about $25,180 over architectural shingles for this roof.
  • Steel shingles: $25,290 to $38,540. Aluminum shingles: $27,960 to $42,620. 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: $34,420 to $52,470. A steel base under a granule finish. You get the tile look at a small part of the weight of real tile.
  • 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.
Metal Through the Maryland Year

Winter decides it here. Metal sheds snow, so ice dams seldom form and the roof lasts longer. In summer a light finish keeps the attic cooler, but skip copper if you want that effect.

Near salt water, choose aluminum or steel with a coating rated for coastal sites; cut edges and scratches on plain steel rust first. Owners who stay put get the most from metal, because the long service life is where the savings sit. Want a firmer metal number? Try the metal roof calculator with your measurements.

Best Season for a New Roof in Baltimore, MD

With winter highs around 43°F, roofers work through most months. Plan the job for spring or fall and get quotes before trouble starts.

Pricing Low-Slope Roofs in Baltimore, MD

A flat roof the size of this home's 2,200 sq. ft. footprint would run, in Baltimore, MD:

  • EPDM rubber: $17,360 to $22,550. Synthetic rubber, usually black, laid in wide sheets with glued or taped seams. It shrugs off hail and hard frost and is easy to patch, so it suits garages, porches and roofs nobody sees.
  • TPO, 60-mil: $14,940 to $19,410. It goes down in sheets that the crew fuses together with a hot-air gun, so there are no glued seams to fail. A common pick when the flat roof sits over a bedroom or a kitchen.
  • PVC, 60-mil: $18,070 to $23,470. It looks like TPO but has a longer service record, and it holds up better where water sits or oils land. Choose it for a busy roof deck or a spot that never drains well.

From cheapest to most expensive here: TPO, then EPDM, then PVC. These figures assume polyiso insulation and one layer removed. Small roofs carry a premium because setup is the same for any size. In Maryland winters, puddles on a flat roof freeze, thaw and creep into the seams. Clear the drains often, and ask for tapered fill at any low spot during the re-roof. Run the flat roof calculator to match a specific membrane and drain layout.

Flat Roofs Through Both Seasons in Baltimore, MD

Freeze and thaw are the main threat here, and summer heat comes second. Welded TPO or PVC handles both: tight seams for the cold and a white face for the heat.

Roof Replacement FAQ: Baltimore, MD

How many working days does a new roof need?

Expect a short job for 24.9 squares of shingles - often a day or two, sometimes more. The crew should tarp or dry-in anything they open before leaving.

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 $11,750 to $17,920 to replace, that gap is large, so check your settlement terms.

How do roofers measure a roof in squares?

Roofers measure surface, not floor area. The 2,200 sq. ft. footprint in this guide turns into about 2,486 sq. ft. of roof at 5/12 - 24.9 squares. Different counts between bids are a red flag.

What permits does a Maryland roofing job need?

In most places, a complete replacement needs a permit and may need an inspection. Your roofer should apply for it; a request that you do it yourself is a warning sign.

Quick Answers

Answers use Maryland averages; energy prices updated October 2026.

What time of year is best for a new roof in Maryland?

Almost any month. Winter highs near 43°F and summer highs near 88°F rarely halt a job in Maryland, so schedule around your plans and ahead of storm season.

Roof replacement calculator

Does a new roof in Maryland need an ice barrier membrane?

In much of Maryland, yes. Winter lows around 25°F bring regular freeze-thaw, and colder, higher areas see ice dams. At minimum, put it in valleys and at roof-to-wall joints.

Roof heat cable calculator

Does metal roofing make sense in Maryland?

It depends on how long you stay. Metal costs more now and lasts much longer; Maryland weather (winter lows near 25°F, summer highs near 88°F) favors neither choice, so compare cost per year of service.

Metal roof cost calculator

Will a lighter roof lower cooling costs in Maryland?

Yes. Summers near 88°F and electricity at 26.1¢ per kWh in Maryland make a reflective roof pay off through lower attic heat and shorter AC run times.

Can new shingles go on top of the old roof?

Sometimes, if only one layer is on now and local code allows a second. A full tear-off costs more but exposes the deck, so rotted boards get replaced rather than buried.
