Quick answer
How much does roofing cost in Maryland?
A full architectural asphalt shingle roof replacement in Maryland typically runs $5.00 to $8.75 per square foot of roof area, which puts most Frederick-area houses between $11,000 and $21,000 torn off and replaced. Standing-seam metal is $11 to $20 per square foot. The variables that move a quote within that range are roof pitch, how many layers come off, how much decking has to be replaced underneath, and the number of valleys, chimneys and skylights that need flashing.
The numbers
Maryland pricing, broken down.
Almost no contractor site in this market publishes a number, which is exactly why the question has so much search demand and so little honest supply. These are the ranges we price to in Maryland, with the reason each one is a range and not a price.
Typical in Maryland
Architectural shingle, torn off and replaced
$5.00 – $8.75 / sq ft
Architectural shingle, tear-off and replace
$5.00 – $8.75 per square foot of roof
Roof area, not floor area — a 1,600 sq ft house with a moderate pitch has roughly 2,000 sq ft of roof, and a steep one has more. The low end is a simple gable; the high end is a cut-up hip roof with dormers.
Typical Frederick-area house, complete
$11,000 – $21,000
Covers most of the detached housing stock here at 1,800 to 2,400 sq ft of roof. Townhouses run well below it; anything over about 3,000 sq ft of roof or with a complex layout runs above.
Three-tab shingle instead of architectural
$4.25 – $6.50 per square foot
Cheaper up front and worth it almost nowhere. Three-tab carries a shorter warranty and a lower wind rating, and the difference in installed cost on a whole roof is usually small enough that it is a poor place to economise.
Standing-seam metal
$11 – $20 per square foot
Two to three times a shingle roof, and lasts two to three times as long. Makes financial sense if you intend to be in the house twenty-plus years, and makes little sense if you intend to sell in five.
Second layer tear-off
+$0.60 – $1.40 per square foot
Plenty of houses here already have two layers because the last roof went over the first. Both come off — roofing over a second layer is how you hide a bad deck and void a shingle warranty at the same time.
Decking replacement, per sheet
$75 – $140 per 4x8 sheet
The honest unknown on every roof. Nobody can see the deck until the shingles are off, so a proper quote prices the sheets at a stated rate rather than pretending there will be none.
Ice-and-water shield, eaves and valleys
$1.10 – $2.40 per square foot covered
Not optional in this climate. Maryland gets the freeze-and-thaw cycle that builds ice dams at the eave, and the membrane is what stops the backed-up water getting under the shingles.
Ridge vent and intake ventilation
$9 – $18 per linear foot
A roof with no path for air is a roof that cooks its own shingles from underneath and shortens their life by years. If a quote does not mention ventilation, that is a question to ask.
Chimney, skylight or wall flashing
$350 – $1,200 each
Where roofs leak, almost always. Step flashing and a proper counter-flashing cut into the mortar is a different thing from a bead of sealant, and only one of the two is still working in year six.
Localised repair rather than replacement
$350 – $1,400
Missing shingles after a storm, a failed pipe boot, a valley re-done. Sensible on a roof with years left and false economy on one near the end.
Permit
$120 – $400
Required in most jurisdictions here for a full replacement. It is also the thing that puts an inspector on your roof, which is free quality control.

Repair or replace, decided properly
Asphalt shingles in this climate give twenty to twenty-five years for architectural and fifteen to twenty for three-tab, and they do not fail gradually in a way you can see from the ground. The signals worth acting on are granules collecting in the gutters, shingles that curl at the corners or feel brittle underfoot, and any staining on the sheathing visible from the attic.
Under about fifteen years, repair. A section of missing shingles, a pipe boot that has split in the sun, or a valley that was flashed badly are all local problems with local fixes, and spending $600 to buy another eight years out of a sound roof is a good trade.
Past twenty, replace, even if only one area is leaking — the rest of the roof is the same age as the part that failed, and patching it means paying for staging and mobilisation twice. The exception is a roof you only need to carry you to a sale, and in that case the honest answer is a repair and a disclosure, not a new roof you will not benefit from.
What "lifetime" means on a shingle warranty
Less than it sounds. A lifetime limited warranty on shingles covers manufacturing defects, prorated after an initial period, and it is voided by inadequate ventilation, by installation that departs from the manufacturer specification, and in many cases by roofing over an existing layer. The failure mode you are actually likely to meet is not a defective shingle; it is a flashing detail or a nail line that was wrong.
Which is why the workmanship warranty matters more than the material one. Ask what it covers, for how long, and who honours it — a manufacturer warranty survives a contractor going out of business, and a workmanship warranty does not.
Why the roof, the gutters and the fascia are one conversation
The eave is where all three meet, and it is where almost every roof problem in this area eventually shows up. The drip edge sits behind the gutter, the fascia carries the gutter, and the ice-and-water shield has to run up from the eave edge far enough to beat an ice dam. Doing the roof and leaving thirty-year-old gutters hanging off soft fascia is how a new roof develops an old roof’s symptoms.
Because we do roofing, gutters and siding, that detail gets decided once. It is also why the roof quote we write usually itemises the fascia condition — not to inflate it, but so you are not surprised by it halfway through the tear-off.
Before you sign anything
What a real written quote should itemise
Ask every contractor for these in writing. Quotes only compare once they do — and Maryland law requires home improvement work over $500 to be under a written contract anyway.
- Roof area in squares or square feet, and how it was measured
- Shingle manufacturer, line and wind rating — not just "architectural"
- Number of layers coming off, and the rate per sheet for replacement decking
- Ice-and-water shield: where it goes and how far up from the eave
- Ventilation: ridge vent, and the intake that makes it work
- Every flashing point listed — chimney, skylights, walls, pipe boots
- Drip edge and the fascia it fastens to
- Dumpster, nail sweep and landscape protection
- Permit, and who pulls it
- Workmanship warranty length, in writing, separate from the shingle warranty

What moves the number
Why two quotes on the same job land far apart.
Usually not because one contractor is expensive. Usually because they are pricing different work. These are the variables that actually move it.
01
Pitch, and how many storeys it is above the ground
Anything over about a 7:12 pitch stops being walkable and starts needing staging and harnesses, which slows every part of the job. A steep three-storey roof can cost 30% more per square foot than the same area at 4:12 over a single storey, for identical materials.
02
What the tear-off finds
The deck is the one thing nobody prices accurately in advance, because it is under the roof. Plank decking with gaps, delaminated OSB around a chimney, or a soft area at a valley all have to be replaced before anything goes back on. A quote that includes zero decking allowance is not optimistic; it is incomplete.
03
How cut-up the roof is
Valleys, hips, dormers, skylights and a chimney are all hand work and all potential leaks. Two houses with the same roof area can differ by thousands if one is a plain gable and the other has four dormers and a cricket behind the chimney.
04
Material, and how long you plan to stay
Architectural shingle is the right answer for most houses here. Metal costs two to three times as much and lasts two to three times as long, so the maths comes down entirely to how long the roof has to serve you. We will run that arithmetic honestly rather than steering you to the bigger invoice.
05
Insurance claim or out of pocket
Storm damage in this area is a real route to a replacement, and a claim changes the process more than the price — the scope is written against the adjuster’s measurements, and the supplements for code items like ice-and-water shield have to be requested. We work either way, and we will tell you plainly whether we think a claim is viable.

Roofing cost questions
Not covered here? Call and ask — you’ll get a real answer, not a “depends on the job”.
Most detached houses here land between $11,000 and $21,000 for a full architectural shingle tear-off and replacement, which works out to roughly $5.00 to $8.75 per square foot of roof. Townhouses are considerably less. Metal runs $11 to $20 per square foot. Your number depends on pitch, layers, how much decking is bad underneath, and how many valleys and penetrations the roof has.
A typical house is one to three days, weather permitting — tear-off and dry-in on day one, and a roof is never left open overnight. A complex or steep roof, or one that needs significant decking replaced, runs longer. Metal takes several days because it is fabricated and fastened rather than nailed in courses.
It is physically possible on a single existing layer and we do not recommend it. You cannot see or fix the deck, the flashing is reused rather than replaced, the extra weight and trapped heat shorten the new shingles’ life, and most manufacturer warranties either reduce or exclude coverage. It saves perhaps 15% today and costs you years off the roof.
Age first: under fifteen years, repair is usually right; past twenty, replacement usually is. Then look for granule loss in the gutters, shingles that curl or crack rather than flex, daylight or staining on the sheathing from inside the attic, and whether the problem is one area or showing up in several. One failed detail on a sound roof is a repair. Several, on an old roof, is a replacement being announced in instalments.
For sudden storm damage — wind or hail — often yes, subject to your deductible and whether the policy pays replacement cost or actual cash value. For a roof that has simply worn out, no; insurers do not cover age. We will look at it and tell you honestly which of the two you have before anyone files anything.
Late spring through autumn is ideal, mainly because asphalt shingles need warmth to seal properly. Winter work is possible and we do it, but the sealant strips bond slowly in cold weather and the crew works shorter days. If the roof is not actively leaking, waiting for better weather is usually the cheaper and better-quality option.
In most jurisdictions here, yes, for a full tear-off and replacement. Small repairs generally do not. We pull it as part of the job. The inspection that comes with it is worth having — it is an independent set of eyes on work you cannot see from the ground.
Yes, and that is the part that makes us different from a roofing-only outfit. Once the roof is dry we handle the wet insulation, the stained or sagging drywall, the framing where it needs checking, and the paint. One contract, one crew, instead of a roofer who leaves and a drywall contractor you have to find.
