What Does Roof Replacement Cost in Maryland and Virginia?
Roof replacement in Maryland costs $9,500 to $20,000 for most homes in 2026, with the typical 2-story colonial running $9,500 to $15,000 and smaller townhomes or ranchers coming in at $5,500 to $8,500. These figures come from 1,460+ inspections JDH Remodeling completed across Southern Maryland and Northern Virginia between 2024 and 2026, not from national averages that ignore local labor and material costs.
The single biggest variable is roof surface area, not the square footage of your living space. A 2,000 sq ft house can have anywhere from 1,800 to 2,800 sq ft of actual roof surface depending on pitch and complexity. Pitch, number of layers being torn off, and whether any decking needs replacement all move the number significantly.
For Virginia homeowners in Stafford, Fredericksburg, and Spotsylvania counties, pricing is comparable to Southern Maryland. JDH holds a Virginia Class A Contractor License (#2705192986) and a Maryland Home Improvement Commission License (MHIC #137491), so both states are covered under the same licensed, insured operation.
A real project example: a 2-story colonial in Prince Frederick, MD with approximately 2,000 sq ft of roof surface, installed with a full Owens Corning Platinum system, came in at $14,900 in 2026. That price included full tear-off, synthetic underlayment, ice and water shield, drip edge replacement, DuraRidge ridge cap, and four sheets of decking.

What Drives the Price Up or Down
Roof replacement pricing in Southern Maryland and Northern Virginia is driven by a small number of measurable factors. Below: what pushes a quote higher, what keeps it lower, and the typical dollar impact JDH sees on 1,460+ inspections.
What Drives the Price UP
These factors add labor time, material, or specialty handling. Most are visible from the ground or during inspection.
Safety rigging required, slower production. Most colonials in Calvert and Charles counties fall in 6/12-8/12; anything above starts adding cost.
Maryland code maxes out at two layers. If your home already has two, both come off before new shingles go down. Doubles the disposal weight and labor.
Every penetration or roof-plane change adds flashing work and precision cuts. A roof with four dormers and two skylights takes meaningfully longer than a simple gable.
~30% of jobs need decking work. JDH includes 4 OSB sheets in every quote; additional sheets are $85 each. We photograph what's found during tear-off and call you the same morning before adding work.
Homes within ~2 miles of tidal water in Calvert, St. Mary's, or along the Chesapeake shoreline need enhanced fastening + stainless hardware against salt-air corrosion.
Longer material lifts and additional safety setup on multi-story homes. 3-story or walkout-basement homes add more.
What Keeps the Price DOWN
These are the conditions where a JDH quote lands in the lower half of its range. If your home fits most of these, expect to be at or near the floor.
Walkable roofs (ranchers, ramblers) don't need safety rigging. Standard production speed, baseline labor.
One layer of shingles to tear off = baseline disposal and labor. Most homes built or re-roofed in the last 20 years are single-layer.
Standard 2-plane gable or hip with one or two roof vents and a chimney is the JDH default. Quotes assume this geometry unless dormers or skylights are present.
If decking is sound (which the inspection predicts in advance), you stay inside the 4-sheet allowance built into every JDH quote. No mid-job surprises.
Homes more than ~2 miles from tidal water don't need stainless hardware or coastal-spec fastening. Most of Prince George's, Anne Arundel inland, and the Fredericksburg corridor fall here.
Single-story homes don't require multi-stage material lifts or extended fall-protection setup. Crew moves faster.
| Factor | Typical Cost Impact | Notes |
|---|---|---|
| Steep pitch (8/12+) | +15-30% labor | Safety rigging required; slower production |
| Two-layer tear-off | +$800-$1,500 | Double disposal weight + labor |
| Roof complexity (dormers, valleys, skylights) | +10-40% labor | Additional flashing and cuts |
| Decking damage / OSB replacement | +$400-$2,500 | $85/sheet beyond 4 included; ~30% of jobs |
| Coastal exposure (within ~2 mi tidal water) | +$1,000-$3,000 | Enhanced fastening, stainless hardware |
| Second-story or higher | +5-15% labor | Longer material lifts, additional safety setup |

What Is Included in a JDH Roof Replacement
Every JDH roof replacement is the full Owens Corning system at a fixed price written before tear-off begins. No post-discovery add-ons after the old roof comes off. That is the standard scope on every project, not an upgrade.
Materials
- Owens Corning Duration shingles - primary weather surface, full color range
- Deck Defense synthetic underlayment - non-absorbent, required for Platinum warranty
- DuraRidge ridge cap - purpose-built, not cut-down 3-tab shingles
- Ice and water shield at all eaves, valleys, penetrations
Application
- Full tear-off of existing shingles and underlayment
- Drip edge replacement on the full perimeter - new metal, not reused
- Four sheets of OSB decking included ($85/sheet beyond if needed)
- Owens Corning Platinum-spec install per manufacturer requirements
Cleanup & Compliance
- Magnetic nail sweep at the end of every workday
- Dump trailer cleanup - all debris hauled, never left on driveway
- County permit and final inspection - JDH pulls every permit
- Fixed price written before tear-off begins
What Other Contractors Often Leave Out
Low bids frequently omit items that are standard in a JDH quote. Felt paper substituted for synthetic underlayment saves the contractor roughly $400 but voids the manufacturer warranty. Reusing drip edge instead of replacing it saves $200 but exposes the fascia to rot. Skipping the permit saves $150 to $400 but leaves the homeowner liable if the work is ever questioned during a sale or insurance claim. Ice and water shield omitted at valleys creates a leak path within a few years. Ridge cap made from cut-down 3-tab shingles instead of a purpose-built product like DuraRidge fails at the peak under high wind.
A second layer of shingles that was not spotted during a walk-and-talk estimate can add $1,200 or more to a low bid after tear-off begins. Post-tear-off decking discoveries at contractors who do not inspect the attic before quoting typically add $900 or more. JDH's inspection methodology - including an attic walk and FLIR thermal imaging - identifies decking issues before the crew arrives, so the quote reflects the actual scope.
Why the full system matters: Owens Corning's Platinum Protection Limited Lifetime Warranty - the 50-year non-prorated coverage that includes materials, labor, tear-off, and disposal - is only available through Platinum Preferred Contractors who install a minimum of four Owens Corning component products beyond the shingles. JDH has held Platinum Preferred status since 2014, which puts it in less than 1 percent of roofing contractors nationally.

Roof Replacement Cost by House Size in Maryland
The table below shows estimated replacement costs by common house sizes in Southern Maryland and Northern Virginia as of 2026. Roof surface area is estimated at a 6/12 pitch; steeper roofs will have more surface area and higher costs. All figures assume a single-layer tear-off, standard complexity, and a full Owens Corning system with Platinum warranty eligibility.
| House Size (Living Area) | Estimated Roof Surface | Low | Typical | High | Notes |
|---|---|---|---|---|---|
| 1,200–1,600 sq ft (rancher/townhome) | 1,100–1,500 sq ft | $5,500 | $6,800 | $8,500 | Single story, simple geometry |
| 1,600–2,000 sq ft (colonial) | 1,500–2,000 sq ft | $8,500 | $10,500 | $13,000 | Standard 2-story, moderate complexity |
| 2,000–2,400 sq ft (colonial) | 1,800–2,400 sq ft | $9,500 | $12,500 | $15,000 | Most common profile in Calvert/Charles |
| 2,400–3,000 sq ft (large colonial) | 2,200–3,000 sq ft | $12,000 | $15,500 | $18,500 | Dormers or higher pitch common |
| 3,000+ sq ft (large/custom) | 2,800+ sq ft | $15,000 | $17,500 | $20,000+ | Complex geometry, steep pitch, coastal |
All figures: Southern Maryland / Northern Virginia, Owens Corning asphalt shingles, 2026. Coastal exposure, steep pitch, or two-layer tear-off add to the high end.
For metal roofing, JDH prices standing-seam and metal panel systems at $15 to $22 per sq ft installed, with a minimum charge of $2,500. A 2,000 sq ft roof surface in metal runs $30,000 to $44,000 - roughly two to three times the cost of architectural shingles. Metal carries a longer service life (40 to 70 years vs. 25 to 30 for architectural shingles) and performs well in coastal salt-air environments.
For financing options that spread the cost over 60 to 120 months, see our Roofing Financing page. JDH works with Foundation Finance, Service Finance, Hearth, and Synchrony. A $12,500 project at 9.99% APR over 60 months runs approximately $266 per month. No deposit is required when financing through an approved provider.
Why the Contractor You Choose Changes the Price and the Outcome
Choosing an Owens Corning Platinum Preferred Contractor over a standard installer is the difference between a 50-year non-prorated warranty and a 25-year prorated one. The credentials below are not marketing labels: they are annual performance reviews, forensic certifications, and documented insurance levels that determine whether a roof quote is defensible six years from now.
Owens Corning Platinum Preferred
12 consecutive years at OC's top contractor tier. The only path to the 50-year non-prorated Platinum Protection warranty: materials, labor, tear-off, disposal covered.

4.9-Star Average
404 Google, 106 Thumbtack, 40 Facebook, plus Angi, Houzz, BBB, Nextdoor profiles. GuildQuality shows 95% of 242 surveyed customers would recommend JDH.
500+ Replacements / Year
Roughly 3 repairs every business day across MD + VA. Production Manager Steve Dean in construction since the 1970s. Roof Foreman Jesus Luna with 32 years field experience.
For homeowners who have been told the price is higher than another quote: the objection is fair. JDH is not the cheapest option in Southern Maryland. The difference is the 50-year non-prorated warranty, the HAAG-certified inspection before every quote, the fixed price before tear-off, and the $8 million liability coverage that protects your home if anything goes wrong.
