Washington D.C. Roof Replacement

Maggio Roofing has replaced more than 10,000 roofs across Washington D.C., Maryland, and Northern Virginia since 1989. Full residential replacements run $9,000 to $35,000 for architectural shingles on a typical DC-area home—more for slate, metal, or designer materials. We’re GAF certified, Certainteed Master Shingle Applicators, certified by every other major roofing manufacturer and EPA Lead-Safe certified, with a written estimate and material samples before any work begins.

How We Approach Every Replacement

1. Free on-roof inspection and measurement. Our estimator gets on the roof, takes accurate measurements, photographs the deck, ventilation, flashing details, and any structural concerns.
2. Material consultation at your home. We bring physical samples—shingle colors, slate, metal panels—so you can see them against your house in actual daylight, not on a screen.
3. Written estimate with line-item pricing. Tear-off, decking repair allowance, underlayment, materials, flashing, ventilation, disposal, and warranty—all in writing before you sign anything.
4. Tear-off down to the deck. We don’t roof over existing shingles. That’s how leaks and warranty problems happen.
5. Full deck inspection and repair. Rotted plywood and damaged framing get replaced before new materials go on. Decking repair is itemized in your estimate so there are no surprise invoices.
6. Installation by our own crews. The same people every day—not subcontractors, not day labor.
7. Final walkthrough and cleanup. Magnetic sweep for nails, debris removed, gutters cleared, and a final inspection with you before we leave.

DC Roof Replacement Cost Ranges

• Architectural asphalt shingles: $12,000 – $25,000 (most common—30-year and 50-year GAF)
• Designer / luxury asphalt shingles: $18,000 – $35,000 (slate-look, shake-look profiles)
• Standing seam metal: $30,000 – $70,000+
• Synthetic slate: $25,000 – $50,000
• Natural slate (Buckingham, Vermont, PA black): $40,000 – $120,000+
• Cedar shake: $25,000 – $50,000
• Flat roof (FiberTite): $6,000 – $35,000 — see our flat roof page

These are honest ranges for the DC metro. Variables include square footage, pitch, number of stories, complexity of valleys and dormers, decking condition, and access (a Cleveland Park rowhouse and a Potomac colonial are not the same job).

Materials We Install

GAF asphalt shingles. Our default recommendation for most DC homes. Timberline HDZ and Timberline UHD are durable 30- and 50-year shingles available in colors and profiles to match every architectural style in the DC area. Color and profile options to match every architectural style in the DC area.

Slate. Real slate (Buckingham, Vermont, Pennsylvania black) is the right answer for many DC historic homes. We’ve worked on 100-year-old slate roofs in Mt. Pleasant, Capitol Hill, Cleveland Park, Chevy Chase, and Kalorama—and we know how to source matching materials and install with copper flashings that last another century.

Synthetic slate. DaVinci and Brava polymer slate offer the look of natural slate at a fraction of the weight (no structural reinforcement needed) and roughly half the price. Excellent option for historic-look homes that weren’t originally built for slate weight.

Standing seam metal. Long lifespan (50+ years), low maintenance, excellent for modern DC contemporary homes and many farmhouse-style suburban builds.

Cedar shake. Available for homes where it fits the aesthetic and HOA. Higher maintenance than other options—we’ll talk through the tradeoffs honestly.

Why DC Roof Replacements Are Different

The DC metro has housing stock most national roofers don’t understand: 100-year-old slate roofs throughout Cleveland Park, Chevy Chase Village, Capitol Hill, and Mt. Pleasant; mid-century shingle roofs across Bethesda, Silver Spring, and Kensington; tight rowhouse lots in Petworth, Brookland, and Bloomingdale with no driveway access; and historic district restrictions in much of NW DC and inside-the-Beltway Maryland. We’ve been replacing these specific roofs for 35+ years. We know what permits are needed, what HOAs allow, what flashing details work on a 1920s rowhouse, and how to stage materials when there’s no driveway and no street parking.

Frequently Asked Questions

How much does a roof replacement cost in DC?

For architectural asphalt shingles on a typical DC-area home, plan on $12,000 to $25,000. Designer shingles, slate, metal, and synthetic slate cost more—up to $120,000+ for natural slate on a large historic home. Every estimate is itemized in writing before you commit.

How long does a roof replacement take?

Most asphalt shingle replacements take one to two days. Slate, metal, and cedar can take a week or longer depending on size and complexity. Weather can extend the timeline—we don’t open a roof if there’s rain in the forecast within the work window.

Do I need a permit for roof replacement in DC?

Yes. DC, Montgomery County, Prince George’s County, and most Virginia jurisdictions require a permit for roof replacement. We pull the permit as part of every job—it’s included in the estimate, not a surprise add-on.

Will my homeowner’s insurance cover a new roof?

For age-related wear, no. For storm, hail, or wind damage, often yes—if the damage is documented and the claim is filed promptly. We work with adjusters from State Farm, USAA, Allstate, Liberty Mutual, and most major carriers, and we’ll meet the adjuster on the roof to walk through the damage.

What’s the warranty on a Maggio Roofing replacement?

Maggio Roofing provides a lifetime workmanship warranty on every replacement. Manufacturer warranty on GAF asphalt shingles runs up to 50 years on materials when installed to spec. Slate and metal carry their own manufacturer warranties.

Can you replace a slate roof in DC?

Yes. Slate replacement is one of our specialties. We source matching slate (Buckingham gray, Vermont green/purple, Pennsylvania black), use copper flashings and copper nails, and install with the techniques required to make a slate roof last another 75-100 years. Historic district approvals included.

Do you offer financing for roof replacement?

Yes. We offer flexible financing through several lenders—fixed-rate and same-as-cash promotional options available depending on the program. See our financing page or ask your estimator at your free inspection.

Will you tear off the old roof or roof over it?

We tear off down to the deck on every replacement. Roofing over existing shingles voids most manufacturer warranties, hides decking damage, adds weight the structure may not be rated for, and shortens the new roof’s lifespan. It’s not worth the savings.

What happens if there’s rot under my shingles?

We inspect every square foot of decking after tear-off. Rotted plywood and damaged framing get replaced before new materials go on. Decking replacement is itemized in your written estimate at a per-sheet price, so the only variable is the count—not the rate.

Do I need to be home during the roof replacement?

No. Most customers go to work as normal. We’ll communicate with you by phone or text if anything needs your decision (most commonly: unexpected decking damage). We secure the site at the end of each day and the property is yours to use normally in the evening.
