Roof Replacement Cost on Maryland's Eastern Shore (2026): Every Price Driver From Our Own Estimates
By Adam Whitaker, owner, Precision Exteriors (MHIC #166640) Last updated: October 25, 2026 Data: 1,327 roofing estimates for 942 jobs, written October 2024 through October 2026
Quick answer
On Maryland's Eastern Shore and in Delaware, Precision Exteriors prices every roof line by line. Tear-off and installation labor runs about $129 to $176 per square (a square is 100 square feet). Owens Corning Duration shingles run about $171 to $253 per square for the material. Steep pitch, extra layers, rotten decking, chimneys, low-slope sections and disposal add to that. Every range on this page comes from our own estimates, not national averages.
All in, three worked examples built from these same prices come to about $12,300 (about $490 per square) for an easy 25-square roof, about $17,000 (about $565 per square) for a typical steep 30-square roof with a chimney and a skylight, and about $31,000 (about $1,035 per square) for a hard 30-square roof.

What does a full roof cost in total?
On Maryland's Eastern Shore, a full roof replacement from Precision Exteriors runs from about $490 per square on an easy roof to about $1,035 per square on a hard one. The three worked examples below show where the money goes. Each one is built only from the prices on this page: the median where we publish one, and the middle of the range where we don't. Your own roof is measured and priced on its own.
Easy roof: about $12,300 (about $490 per square)
A 25-square (2,500 square foot) one-story ranch with a simple gable roof, one layer of old shingles, a 6/12 pitch, no chimney and no skylights. The decking is sound, and the supplier can load the shingles onto the roof.

Medium roof: about $17,000 (about $565 per square)
A 30-square (3,000 square foot) two-story house with a 10/12 pitch, a hip roof with several valleys, one chimney and one skylight that stays in place and gets new flashing. One layer of old shingles, and the decking is sound.

Hard roof: about $31,000 (about $1,035 per square)
A 30-square (3,000 square foot) roof with a 12/12 pitch throughout, two layers of asphalt shingles over original cedar shakes, and one chimney. The cedar was nailed over skip sheathing, so the whole deck gets new plywood. The cedar is bulky, so the debris goes in an extra-large dumpster.
| Line item | Quantity | Price used | Amount |

The plywood count is 94 sheets to cover 3,000 square feet, plus about 10% for cuts. None of the examples includes a permit ($231 to $1,000 when we pull it) or the optional Owens Corning Platinum Protection warranty ($16 to $20 per square).
How we made this guide
Every price on this page comes straight out of the quoting software Precision Exteriors uses to write estimates. These aren't national averages or numbers copied from another website. They're the line-item prices we gave our own customers on 1,327 roofing estimates for 942 jobs, written between October 2024 and October 2026. An estimate counts as a roofing estimate if it has at least one roofing line item. Some jobs got more than one estimate, which is why there are more estimates than jobs.
We report the middle 80% of non-zero prices for each line item. Starter and hip and ridge prices come from the 21 starter lines and 20 hip and ridge lines on estimates written in August 2026. Where we haven't quoted an item often enough to give a reliable range, we say so and price it job by job. Your roof is measured and priced on its own, so your total depends on what your house needs. These are the same line items you'll see on a Precision Exteriors estimate.
Part 1: What your roof requires
These are costs set by your roof's condition, the building code or your site. Precision Exteriors doesn't skip them, and neither would any contractor doing the job right.
Extra layers of shingles
Removing a second layer of shingles costs about $43 to $55 per square, usually $50, on a Precision Exteriors estimate. If someone roofed over the old shingles instead of tearing them off, both layers have to come off. That's more labor and more weight going to the landfill. It was on 187 of our 1,327 roofing estimates.
Cedar shake removal
Cedar shake removal costs about $71 to $93 per square, on top of the normal tear-off. Cedar comes off slower than asphalt, and it's often nailed over skip sheathing that has to be dealt with before new shingles can go on.
Metal roof removal
Removing old metal roof panels costs about $71 to $91 per square. It means pulling fasteners, cutting panels and hauling awkward pieces.
Slate and flat-roof removal
Slate removal and old built-up flat roof removal are priced per square after we see the roof. Slate is heavy, slow to remove and costly to haul away, and an old flat roof can be several layers deep. We haven't quoted enough of either to give a reliable range.
Taking down an old chimney
Taking down an unused, failing chimney below the roofline and decking over it has cost about $250 to $760 per chimney, depending on size and condition.
Dump fees and dumpsters
Disposal on a Precision Exteriors estimate usually runs $43 to $55 per square of roof, because landfills charge by weight. Roofs under 20 squares cost more per square to dispose of, about $59 to $93. Cedar shake is bulky, so a cedar tear-off can need a larger dumpster, and the larger dumpster costs more. When a job needs a dumpster on site, we size it to the debris:
- Small (1 to 3 tons): about $540 to $680
- Medium (about 4 tons): about $670 to $900
- Large (5 to 7 tons): about $930 to $1,190
- Extra-large (7 to 8 tons): about $1,150 to $1,870
Steep pitch
Precision Exteriors charges a steep fee starting at 8/12 pitch, per square of the steep area only. On a steep roof, crews work tied off and set roof jacks and planks, and every square goes slower.
- 8/12 to 9/12: about $21 to $27 per square
- 10/12 to 11/12: about $43 to $55 per square
- 12/12: about $63 to $82 per square
- 13/12 and steeper: about $143 to $161 per square (only a couple of jobs, so treat it as a rough guide)
463 of our 1,327 roofing estimates had some steep area.
Dormers
A dormer fee runs about $214 to $250 per dormer. Every dormer adds short runs, extra cuts, flashing and ladder moves. It doesn't come up often.
Two-story and hard-to-reach roofs
Two-story access charges and crane rental are priced job by job. Height means more ladder and safety setup and slower material handling. A few jobs have needed a separate two-story access charge, and a handful, including 3-story homes, needed a crane.
Low-slope and flat sections
Low-slope sections are priced as their own system, because the building code doesn't allow shingles on a roof flatter than 2/12. Porch roofs, additions and flat sections get a membrane instead.
- TPO membrane, mechanically fastened: about $500 to $1,190 per square for labor, plus membrane, insulation board and edge metal
- Polyiso insulation board: about $57 to $73 per 4x8 board
- Owens Corning DeckSeal self-adhered modified bitumen, often used where a low-slope section ties into a shingle roof: cap sheet about $194 to $280 per roll (1 square), base sheet about $200 to $282 per roll (2 squares)
117 of our 1,327 roofing estimates had a low-slope section.
Rotten or damaged decking
Replacement decking found during tear-off is $65 per sheet of OSB, $75 per sheet of CDX plywood and $8 per linear foot of 2x framing on our standard Precision Exteriors estimate. Nobody can see the decking under your shingles until the old roof comes off, so we put those prices in writing up front. When the inspection already shows bad sheets, we list them as planned line items instead:
- Install 7/16" OSB: about $32 to $45 per sheet for labor, plus about $29 to $88 per sheet for the OSB (median $43)
- Install plywood: about $36 to $50 per sheet for labor, plus about $39 to $55 per sheet for 1/2" CDX
465 of our 1,327 roofing estimates included some planned decking.
Code-required decking
Re-sheathing a deck that doesn't meet code is priced per sheet, the same as decking replacement. Shingles have to go on a solid deck. Old plank boards with wide gaps, for example, have to be sheathed before we can install the new roof and the manufacturer will issue the warranty.
Crickets behind chimneys
A cricket runs about $143 to $182, and some of our estimates include it at no charge. The code requires a cricket (a small framed peak that sends water around the chimney) behind any chimney more than 30 inches wide, because a wide chimney on the uphill side traps water and debris.
Drip edge and rake edge
New aluminum drip edge costs about $14 to $23 per 10-foot piece, and rake edge about $9 to $21 per 10-foot piece. The code calls for drip edge at the eaves and rake edges of a shingle roof. Precision Exteriors installs new edge metal around the whole perimeter, so water drips into the gutter instead of rotting the fascia.
Wall flashing, and removing siding to do it right
Step flashing costs about $80 to $129 per bundle of 50 pieces, and sidewall or endwall flashing about $43 to $60 each. Wherever a roof meets a wall, we install new flashing. The code says the vertical leg has to run up behind the siding, lapped so water can't get into the wall. On many houses the only way to do that properly is to remove the bottom courses of siding along the roofline, flash and tape it, and put the siding back. That labor is priced job by job, because it depends on the siding type and how many walls the roof touches.
Bath fans that vent into the attic
A new exhaust cap costs about $33 to $48 for a 4-inch cap and $96 to $133 for a 6-inch cap with a damper. The code says bathroom exhaust has to go directly outdoors, not into an attic, soffit, ridge vent or crawl space. When we open a roof and find a bath fan blowing warm, wet air into the attic, we run it out through the roof. The ductwork and labor are priced job by job.
Permits
When Precision Exteriors pulls the permit for you, it has cost about $231 to $1,000, depending on the jurisdiction and the size of the job. Every estimate we write notes whether a permit is required.
Ground drop deliveries
A ground drop costs about $15 to $18 per square. Normally our supplier, ABC Supply or QXO, loads shingles straight onto the roof from the delivery truck. When power lines are in the way, or the homeowner doesn't want the truck on the driveway, materials are dropped on the ground and our crew carries every bundle up by hand.
Material delivery with unload
Delivery with unload service runs about $303 to $784 per job when materials have to be delivered and unloaded onto the roof as a separate service.
Part 2: What we recommend so your roof lasts its warranted life
Some of these go beyond the code minimum. Precision Exteriors includes them because the shingle makers' instructions and top-tier warranties call for them, and because that's what it takes to build a roof that lasts as long as it's warranted. The actual guarantee comes from the manufacturer's warranty, and we'll give you that document. If you want to talk about trimming any of these, ask us and we'll walk you through what changes.
Starter shingles on the eaves and the rakes
Precision Exteriors always installs starter shingles along the rakes as well as the eaves. Owens Corning Starter Strip Plus has run about $126 to $149 per bundle, and each bundle covers 105 feet of roof edge. Starter shingles give the first course of shingles a sealed edge to hold onto, so running them up the rakes too helps keep wind from lifting the shingles along the gable ends.
Ice and water shield
Standard ice and water shield costs about $117 to $208 per roll (each roll covers 2 squares). Precision Exteriors runs 3 feet of it along the eaves and in the valleys, and around chimneys, walls, skylights and vents.
Is it required in Maryland? The building code requires an ice barrier at the eaves only in places the local building department has marked as having a history of ice dams. Where it applies, it has to reach at least 24 inches inside the exterior wall line. The county design tables we found for the Shore counties we serve either say "No" or don't list it, so in most of our area the code doesn't require it.
We install it anyway because the manufacturers call for it:
- CertainTeed requires it at the eaves for its top SureStart PLUS coverage on homes north of North Carolina, which includes all of Maryland and Delaware. CertainTeed also requires it around penetrations and under closed valleys.
- Owens Corning's shingle instructions call for it at the eaves wherever roofs can leak from ice and water backup.
- GAF requires leak barrier in valleys and around dormers, walls, chimneys, vents and skylights for its Golden Pledge warranty.
Why it's better: it sticks to the deck and seals around every nail. Water that backs up behind ice, or gets blown under the shingles in a nor'easter, has nowhere to go.
High-temperature ice and water shield
High-temperature ice and water shield costs about $191 to $309 per roll. We use it under metal roofs and on some low-slope areas. Regular membranes can soften and slide under a hot metal roof; the high-temp version is rated for it.
Synthetic underlayment
Synthetic underlayment costs about $93 to $225 per roll, and each roll covers 10 squares. Owens Corning ProArmor sits toward the top of that range. It's what Owens Corning's Platinum warranty calls for, and it keeps the deck dry if it rains during the tear-off. We use it instead of old-style felt paper.
New chimney flashing
New chimney flashing costs about $214 to $273 per chimney, and it was on 314 of our 1,327 roofing estimates. We grind it into the mortar joints about half an inch so it's locked into the brick. Chimneys are one of the most common leak spots on a roof. The code says flashing that's rusted, damaged or worn out has to be replaced when you reroof, and Owens Corning, GAF and CertainTeed all require new metal flashing for their top warranties.
New pipe boots and exhaust caps
Every plumbing vent gets a new pipe boot, usually $20 to $41 each. Bath and kitchen exhaust caps are replaced too: about $33 to $48 for a 4-inch cap and $96 to $133 for a 6-inch cap with a damper. The rubber on an old pipe boot usually gives out before the shingles do, and that leak shows up on your ceiling, not on the shingle warranty.
Skylight flashing
A new VELUX flashing kit costs about $127 to $240 per skylight. Every skylight we keep or replace gets one, because VELUX requires its own flashing for its 10-year installation warranty.
Valleys
Valleys carry more water than any other part of the roof. Our standard scope puts ice and water shield in every valley. Where the design calls for open metal valleys, W-valley metal costs about $2.86 to $3.33 per linear foot installed.
Ridge vent
Ridge vent with a weather protector costs about $18 to $30 per 4-foot piece, and 775 of our 1,327 roofing estimates included ridge vent. A roof that can't breathe cooks the shingles from underneath and traps moisture in the attic.
Box vents and power vents
When a roof can't take a ridge vent, or needs help pulling air, Precision Exteriors uses one of these:
- Static box vents: about $55 to $67 each
- Solar-powered attic vents: about $790 to $980 each
- Thermostat-controlled power attic vents: about $363 to $497 each
Adding intake ventilation on older homes
DCI SmartVent intake is priced job by job, based on how many feet of roof edge need it. A ridge vent only works if fresh air can get in down low, and many older Shore homes were built with little or no soffit venting. Maryland had no statewide building code until the Maryland Building Performance Standards Act of 1993, and those standards didn't apply to permits until August 1, 1995 (August 1, 1997 in places that had no code of their own as of October 1, 1992).
SmartVent is a low-profile intake vent that goes under the first courses of shingles at the roof edge, covered with ice and water shield. DCI rates it at 9 square inches of net free air per foot. Today's code calls for 1 square foot of vent area for every 150 square feet of attic, or 1 for every 300 when intake and exhaust are balanced the way the code describes. GAF's Golden Pledge warranty requires balanced intake and exhaust. Owens Corning's Platinum warranty requires a ventilated deck and doesn't cover damage from poor ventilation. CertainTeed requires ventilation that meets code.
Owens Corning Platinum Protection warranty
Platinum Protection costs about $16 to $20 per square. It's an optional upgrade, available only on roofs built to Owens Corning's full-system requirements, and Precision Exteriors always recommends it. As an Owens Corning Platinum Preferred Contractor, we register it with Owens Corning within 60 days of installation. It covers the whole Owens Corning roofing system, including workmanship for a set period, as long as the roof is built to Owens Corning's system requirements. Those include their shingles, underlayment and hip and ridge, plus two of these three: their ice and water barrier, starter shingles or VentSure ventilation. They also require new metal flashing and drip edge. Check the warranty itself for exactly what's covered and for how long.
Part 3: What we recommend to protect your property
The Equipter roof buggy
The roof buggy is a flat charge of about $143 to $182 per job, and it was on 819 of our 1,327 roofing estimates. Precision Exteriors brings an Equipter RB4000, a motorized debris cart that tows to the job and then drives itself across the yard. We park it right under the roof edge, so old shingles and nails go straight into its container instead of onto your lawn, shrubs or flower beds.
- Its lids open to catch debris across about 10 1/2 feet.
- The container can roll back over beds and low shrubs to shield them.
- It rides on wide tires with a lightweight aluminum container, which Equipter designed so it doesn't rut lawns.
- Because the buggy hauls the debris, there's much less foot traffic through your yard.
When it's full, we drive it to the trailer, truck or dumpster and empty it there.
Dumpster skates
When a dumpster sits on your driveway, our dumpster partner sets it on dumpster skates so the steel never touches your concrete or asphalt. A loaded dumpster is heavy, and the skates help keep it from gouging or cracking the driveway.
Keeping heavy supply trucks off fragile driveways
Shingle delivery trucks can weigh 40,000 pounds or more, so we don't recommend them on a driveway that's badly cracked or newly installed. In those cases we'll suggest a ground drop instead (see Part 1). Either way, we tarp and protect landscaping, driveways and decks at no charge, and we run a magnetic roller over the yard for nails.
Part 4: Upgrades you can choose
None of these are needed for a sound roof. They're choices about looks, materials and comfort, and we're glad to price any of them.
Shingle brand and product line
Owens Corning TruDefinition Duration, our most common shingle, costs about $171 to $253 per square for the material. Precision Exteriors also installs GAF and CertainTeed shingles. Designer and specialty lines cost more than standard architectural shingles because they're heavier, thicker or made to look like slate or shake. We haven't quoted enough of the other lines to give a reliable range, so we price those job by job. Our most-installed Owens Corning colors are Driftwood and Onyx Black.
Synthetic slate and shake: F-Wave and DaVinci
Synthetic slate and shake are priced job by job, and they cost more than asphalt shingles. They also need their own starter, hip and ridge pieces.
- F-Wave REVIA shingles carry a Class A fire rating and a Class 4 hail rating. Their WeatherForce Advantage warranty runs 50 years on a single-family home, with the first 15 non-prorated.
- DaVinci Roofscapes synthetic slate and shake are Class A fire rated and Class 4 impact rated, with a Lifetime Limited Material Warranty for homeowners.
Copper
Copper costs several times what aluminum does, and it's usually chosen for historic homes or to match existing details. It's not common for us.
- Copper step flashing: about $11 to $13 per piece
- Copper drip edge: about $107 to $126 per 10-foot piece
- Sheet copper: about $11 to $13 per pound
Skylights
Skylight install labor runs about $143 to $263 per skylight. Older skylights are often worth replacing while the roof is open, and every skylight needs its own flashing kit.
- New VELUX skylights without a shade: about $430 to over $1,100, depending on size and type
- VELUX skylights with a factory-installed shade: about $900 to $1,540. VELUX now makes a solar-powered room-darkening shade with a remote standard on its Skylight System.
- VELUX Solar Powered "Fresh Air" skylights open and close by remote with no wiring, and a rain sensor closes them automatically when it starts to rain. Priced job by job.
New gutters while the roof is open
Seamless aluminum gutters with hidden hangers cost about $8.33 to $10 per linear foot for 5-inch and $9.23 to $12 per linear foot for 6-inch. 145 of our roofing estimates included 5-inch gutters and 31 included 6-inch.
Other roof types
This guide covers asphalt shingle roofs, which are most of what Precision Exteriors installs. Metal, flat and low-slope, cedar shake, slate and synthetic roofs are priced as their own systems. See our pages on metal roofing, flat roofing, cedar shake roofing, slate roofing and F-Wave synthetic roofing.
What Precision Exteriors doesn't charge for
These never appear as line items on our roofing estimates:
- Travel or mileage, anywhere in our service area, including Delaware
- A "cut-up" or complexity fee (the only geometry charges are the steep fee and the dormer fee)
- Tarping and protecting your landscaping, driveway and deck
- Cleaning out your existing gutters at the end of the job (new gutters are priced separately if you're replacing them)
Roofs in historic districts
Precision Exteriors has done a lot of roofs in Eastern Shore historic districts. If your home is in a local historic district, the town may need to approve the work before it starts, and that review can limit which materials you can use. Ask us early so the approval fits the schedule. Copper details and synthetic slate (see Part 4) are common choices on historic homes.

Frequently asked questions
How much does a new roof cost on Maryland's Eastern Shore?
At Precision Exteriors, tear-off and installation labor runs about $129 to $176 per square, and Owens Corning Duration shingles run about $171 to $253 per square for the material. Underlayment, ice and water shield, flashing, vents, disposal and anything your roof requires (steep pitch, extra layers, decking) are added line by line. All in, our worked examples come to about $12,300 (about $490 per square) for an easy 25-square roof, about $17,000 (about $565 per square) for a 10/12, 30-square roof with hips, valleys, a chimney and a skylight, and about $31,000 (about $1,035 per square) for a steep 30-square roof with two old layers, cedar shakes and all-new plywood.
Does a second layer of shingles cost more to remove?
Yes. Precision Exteriors charges about $43 to $55 per square, usually $50, to remove a second layer. It was on 187 of our 1,327 roofing estimates.
What happens if the roof decking is rotten?
Precision Exteriors lists the replacement price on every estimate before work starts: $65 per sheet of OSB, $75 per sheet of CDX plywood and $8 per linear foot of 2x framing. You only pay for what actually has to be replaced.
Does a steep roof cost more?
Yes, starting at 8/12 pitch. Precision Exteriors charges a steep fee only on the steep area: about $21 to $27 per square at 8/12 to 9/12, $43 to $55 at 10/12 to 11/12, and $63 to $82 at 12/12.
Is ice and water shield required in Maryland?
In most of the Eastern Shore, the building code doesn't require it, because the county design tables don't list a history of ice dams. Precision Exteriors installs it at the eaves, in the valleys and around penetrations anyway, because Owens Corning, GAF and CertainTeed call for it for their top warranties. It runs about $117 to $208 per 2-square roll.
How much is a roofing permit?
When Precision Exteriors pulls the permit, it has cost about $231 to $1,000, depending on the jurisdiction and the size of the job.
Do you charge more for Delaware or for long drives?
No. Precision Exteriors uses the same line items and the same price list everywhere it works, with no travel or mileage charges.
What is the roof buggy on my estimate?
It's an Equipter RB4000 motorized debris cart that catches old shingles and nails at the roof edge so they don't land in your yard. It's a flat charge of about $143 to $182 per job.
Do you help with insurance claims?
Yes. Precision Exteriors does storm damage repair and helps homeowners with insurance claims. Call (443) 675-6485.
