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 between 2024 and 2026, not from national averages that ignore local labor and material costs.
Ranchers, townhomes, and smaller single-story homes with straightforward geometry.
The most common home profile in Southern Maryland. Full Owens Corning system with Platinum warranty.
Steep pitches (8/12+), multiple dormers, skylights, coastal exposure within 2 miles of tidal water.
Per-square-foot pricing on roof replacement in Southern Maryland varies with the shingle line, geometry, and complexity. Figures below are 2026 installed prices over roof surface area, not house living area. A typical 2,000 sq ft house has approximately 1,800 to 2,200 sq ft of roof surface at a 6/12 pitch.
| Roof Type | Per Sq Ft Installed | What's Included |
|---|---|---|
| Asphalt shingle, baseline | $4.50 - $7.00 | Standard OC Duration system, simple gable, 6/12 pitch, single-layer tear-off |
| Asphalt with Platinum warranty | $5.50 - $8.50 | Full OC Total Protection Roofing System; 50-year non-prorated warranty |
| Premium / steep / complex | $7.50 - $11.00 | 8/12+ pitch, dormers, coastal hardware, two-layer tear-off |
| Metal (standing-seam) | $15.00 - $22.00 | In-house custom-fabricated standing-seam, $2,500 minimum, 40 to 70 year life |
Per-sq-ft figures are 2026 installed prices in Southern Maryland. A 2,000 sq ft roof surface with a typical OC Platinum system runs $11,000 to $17,000, matching the per-project ranges above.
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.

Roof replacement pricing in Southern Maryland 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.
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.
About 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 and 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.
Walkable roofs (ranchers, ramblers) don't need safety rigging. Standard production speed, baseline labor.
One layer of shingles to tear off means 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 and Anne Arundel inland 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 |
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.
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.
The Remodeling Magazine 2025 Cost vs. Value Report (South Atlantic region, which includes Maryland) tracks resale recovery on common home-improvement projects. Roof replacement consistently lands in the top quartile for return on investment, particularly when the roof is replaced before listing.
| Project Type | 2025 Avg Cost | Value Recouped | ROI |
|---|---|---|---|
| Asphalt shingle re-roof (mid-range) | $30,680 | $18,800 | 61.3% |
| Stone-coated steel roof | $60,150 | $34,260 | 56.9% |
| Kitchen remodel (mid-range) | $83,800 | $32,500 | 38.8% |
| Bathroom remodel (mid-range) | $28,500 | $11,400 | 40.0% |
Source: Remodeling Magazine, 2025 Cost vs. Value Report, South Atlantic region (DE, MD, VA, NC, SC, GA, FL, WV, DC). Mid-range asphalt re-roof returns 61.3% at resale; specific homes vary based on neighborhood, condition, and time of sale.
Beyond raw ROI, three things change at resale when the roof has been replaced:
First, homes with a roof older than 15 years routinely lose a sale to inspection contingency. A buyer's home inspector flags end-of-life shingles, the buyer asks for $10,000 to $20,000 off, and the seller either takes the hit or watches the deal die. Replacing the roof before listing eliminates that negotiation entirely.
Second, insurance carriers in Maryland are aggressively non-renewing homes with roofs over 15 to 20 years old, especially after the 2024 hail seasons. A buyer who can't get homeowners insurance can't close on a mortgage. A new roof with documented Owens Corning Platinum warranty paperwork prevents the carrier issue at the closing table.
Third, appraisers credit a new roof on a comparative market analysis. The credit varies by market but typically lifts appraised value by $5,000 to $12,000 for a recently completed asphalt shingle replacement, more for metal. The JDH replacement paperwork (Platinum warranty registration, county permit, before-and-after inspection photos) is what the appraiser uses to verify the work.
The table below shows estimated replacement costs by common house sizes in Southern Maryland 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 ftrancher / townhome | 1,100-1,500 sq ft | $5,500 | $6,800 | $8,500 | Single story, simple geometry |
| 1,600-2,000 sq ftcolonial | 1,500-2,000 sq ft | $8,500 | $10,500 | $13,000 | Standard 2-story, moderate complexity |
| 2,000-2,400 sq ftcolonial | 1,800-2,400 sq ft | $9,500 | $12,500 | $15,000 | Most common profile in Calvert/Charles |
| 2,400-3,000 sq ftlarge colonial | 2,200-3,000 sq ft | $12,000 | $15,500 | $18,500 | Dormers or higher pitch common |
| 3,000+ sq ftlarge / custom | 2,800+ sq ft | $15,000 | $17,500 | $20,000+ | Complex geometry, steep pitch, coastal |
| 2,200 sq ftcolonial / split-level | 2,000-2,400 sq ft | $10,500 | $13,500 | $16,000 | Common in Bowie, Waldorf, La Plata |
All figures: Southern Maryland, 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.
JDH Remodeling has performed 1,460+ inspections across five counties in Southern Maryland between 2024 and 2026. Pricing shifts modestly across counties based on housing stock, coastal exposure, and permit fees. Below: typical 2026 replacement price by county, with the county-specific factors that move the number.
Coastal county on the Chesapeake Bay. Homes within ~2 miles of tidal water need enhanced fastening and stainless hardware against salt-air corrosion, which adds $1,000 to $3,000. Steep coastal pitches push the high end. 320+ JDH replacements since 2024.
Highest-volume JDH territory: 410+ replacements since 2024. Most are 2-story colonials on the Waldorf/La Plata corridor at 6/12 pitch with single-layer tear-off, which keeps pricing in the standard range. Inland, no coastal upcharge.
Mixes inland colonials with coastal waterfront near Pax River and the Potomac. Military relocations drive steady fast-turnaround inspection volume. Coastal premium near rivers; inland pricing matches Charles County. 240+ replacements since 2024.
Largest premium range in the service area: waterfront homes in Annapolis/Edgewater carry coastal hardware requirements and steeper pitches; inland Crofton runs the baseline. Higher Annapolis city permit fees add modestly. 180+ replacements since 2024.
Housing stock is dominated by 1,800 to 2,500 sq ft colonials and split-levels at simple geometry, which keeps the median in line with Charles County. Higher-density urban permit fees add modestly in Hyattsville/College Park. 210+ replacements since 2024.
County pricing reflects JDH inspection data 2024-2026; figures are typical replacement projects (1,800-2,400 sq ft roof surface). Smaller townhomes start at $5,500; large coastal or complex projects can exceed $20,000. Free inspection includes county-specific factor review.
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.
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.
The same HAAG forensic classification insurance adjusters and legal experts use for damage analysis. Your inspector reads your roof the same way a claim reviewer would.
$8M general liability coverage, workers' compensation insurance, and a surety bond. If anything goes wrong on your property, the coverage is documented and verifiable before work begins.
Maintained BBB A+ accreditation with no unresolved complaints. Independent reviewer that verifies business practices, complaint response, and contract follow-through.
1,400+ verified reviews across Google, Thumbtack, Facebook, Angi, Houzz, BBB, and Nextdoor. GuildQuality shows 95% of 242 surveyed customers would recommend JDH.
Roughly 3 replacements every business day across Maryland. 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.
