The Cost Range

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.

Cost Factors

What Drives the Price Up or Down

Five factors account for most of the price variation on a Southern Maryland or Northern Virginia roof replacement: roof size, pitch, tear-off layers, decking condition, and coastal exposure. Understanding each one helps you read a quote accurately and spot what a low bid is leaving out.

Roof surface area vs. house square footage

Contractors price roofing by the square (100 sq ft), not by your home's living area. A 2,200 sq ft house with a 6/12 pitch has roughly 2,400 sq ft of roof surface. The same house with a 10/12 pitch has closer to 3,000 sq ft. That difference alone can add $3,000 to $5,000 to the project.

Pitch

Roofs steeper than 8/12 require safety rigging and slower labor. JDH prices steep-pitch work at a 15 to 30 percent labor premium over a standard 4/12 to 6/12 roof. Most colonials in Calvert and Charles counties fall in the 6/12 to 8/12 range.

Number of tear-off layers

Maryland building code allows a maximum of two layers of shingles on a residential roof. If your home already has two layers, both must come off before new shingles go down. A two-layer tear-off adds $800 to $1,500 to the project cost due to double the disposal weight and labor.

Decking damage

About 30 percent of JDH replacements require some decking work. JDH includes four sheets of OSB in every replacement quote. Additional sheets run $85 each. The inspection predicts decking needs before tear-off in most cases, so you are not getting a surprise call mid-job. When rot is found during tear-off, JDH photographs it and calls the homeowner the same morning before any additional work begins.

Coastal exposure

Homes within roughly two miles of tidal water in Calvert County, St. Mary's County, or along the Chesapeake Bay shoreline require enhanced fastening patterns and stainless hardware to resist salt-air corrosion. That adds $1,000 to $3,000 depending on the home's exposure level.

Complexity: dormers, valleys, skylights, chimneys

Each penetration or change in roof plane requires additional flashing work and more precise cuts. A roof with four dormers and two skylights takes meaningfully longer than a simple gable. JDH prices complexity at a 10 to 40 percent labor premium depending on the scope.

FactorTypical Cost ImpactNotes
Steep pitch (8/12+)+15–30% laborSafety rigging required; slower production
Two-layer tear-off+$800–$1,500Double disposal weight + labor
Roof complexity (dormers, valleys, skylights)+10–40% laborAdditional flashing and cuts
Decking damage / OSB replacement+$400–$2,500$85/sheet beyond 4 included; ~30% of jobs

What's Included

What Is Included in a JDH Roof Replacement

Every JDH roof replacement includes the full Owens Corning roofing system — shingles, synthetic underlayment, ridge cap, ice and water shield, and drip edge — at a fixed price written before tear-off begins, with no post-discovery add-ons after the old roof comes off. That is the standard scope on every project, not an upgrade.

  • Owens Corning Duration shingles — the primary weather surface, available in a full color range
  • Deck Defense synthetic underlayment — non-absorbent, required by Owens Corning for Platinum warranty eligibility
  • DuraRidge ridge cap — purpose-built ridge product, not cut-down 3-tab shingles
  • Ice and water shield at all eaves, valleys, and penetrations
  • Drip edge replacement on the full perimeter — new metal, not reused
  • Full tear-off of existing shingles and underlayment
  • Dump trailer and magnetic nail sweep cleanup — rolling magnetic sweep at the end of every workday
  • Four sheets of OSB decking — additional sheets at $85 each if needed
  • County permit and final inspection when required — JDH pulls every permit
  • Fixed price before tear-off begins

Watch Out For This

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.

By House Size

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 SurfaceLowTypicalHighNotes
1,200–1,600 sq ft (rancher/townhome) 1,100–1,500 sq ft $5,500 $6,800 $8,500 Single story, simple geometry

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.

Credentials & Proof

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 — and that gap in coverage is why JDH quotes are priced differently than lower bids from contractors who cannot offer the same warranty tier. The credential is not a marketing label; it is an annual performance review Owens Corning conducts based on installation volume, customer satisfaction scores, and verified training.

JDH has held Owens Corning Platinum Preferred Contractor status since 2014 — 12 consecutive years at the top tier of Owens Corning's contractor program. Fewer than 1 percent of roofing contractors in the country hold this designation. Platinum Preferred status is the only way a homeowner can access the Owens Corning Platinum Protection Limited Lifetime Warranty, which covers materials, labor, tear-off, and disposal for 50 years non-prorated, with 25 years of full non-prorated workmanship coverage.

Owner Jim Dodson holds HAAG Certified Inspector: Master Level certification, earned in 2018. Inspector Manager Brian McClees holds the same credential. HAAG Master Level is the same forensic classification used by insurance adjusters and legal experts for damage analysis. It means the person inspecting your roof before the quote is written is using the same methodology an adjuster would use to evaluate a claim.

JDH carries $8 million in general liability coverage, workers' compensation insurance, and a surety bond. The company holds a BBB A+ rating and has maintained BBB accreditation since 2021.

Across 404 Google reviews, 106 Thumbtack reviews, 40 Facebook reviews, and verified profiles on Angi, Houzz, BBB, and Nextdoor, JDH holds a 4.9-star average. GuildQuality, an independent third-party customer satisfaction platform, shows 95 percent of 242 surveyed JDH customers said they would recommend the company.

JDH completes 500 or more roof replacements every year and roughly three roof repairs every business day across Maryland and Virginia. The inspection team has completed 1,460 documented inspections between 2024 and 2026. Production Manager Steve Dean has been in the construction industry since the 1970s. Roof Foreman Jesus Luna has 32 years of 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.
