Roof Replacement Cost in District of Columbia (2027 Price Guide)
Not your house? Change the size or pitch in District of Columbia
Pitch drives both the roof area and the labor. Steep pitches (9/12 or more) slow the crew down, and low ones need extra underlayment care. Our DC starting value is 5/12.
Expect quotes near $13,110 to $19,980 for a standard shingle re-roof in Washington, DC; that figure assumes a typical 2,230 sq. ft. single-story house. That covers a 5/12 roof of about 2,520 sq. ft. - 25.2 squares - with tear-off of the current shingles, new materials and the crew.
Ask any roofer for a per-square price and compare it with ours: $634.00 per square, installed. Two common step-ups: architectural 50-year shingles at $14,560 to $22,200, and steel shingles, the entry metal, from about $28,190.

Price per Year of Roof
The real cost of a roof is price divided by the years it lasts. Hover a bar: metal costs more up front and less per year.
Service lives follow the climate-bell model above (asphalt peaks in moderate regions; metal assumes correct installation); prices are the Washington, DC estimates above.
Why Washington, DC Roofing Bids Differ
Most of the spread between roofers comes from a handful of line items. For a 25.2-square roof at Washington, DC prices:
- Strip and haul. Expect roughly $3,830 of the bid for one layer off. Each extra layer underneath raises it again, by about $2,480 for the second.
- Roof shape. When every side of the roof slopes down to a gutter (a hip design), add close to $1,580 over a two-sided gable. Plenty of dormers and valleys raise the add-on to about $2,670.
- Access. Raise this roof a story and expect about $1,140 on top of the price, for staging, hauling and slower work.
- Openings. Plan near $380 per skylight that gets replaced or added while the roof is open.
- Bad wood. Damaged decking is the most common mid-job extra. Agree on a price per sheet before work starts.
- Metal details. Drip edge, step flashing and vent boots are cheap to replace during a re-roof; make sure each quote says whether they are new or reused. For gutters, see the gutter cost calculator.
- Permit, dumpster, cleanup. Each town sets its own fees. Get them written into the price, along with a magnetic nail sweep of the yard.

Roof size and pitch stay fixed (2,520 sq. ft., 5/12); only the scope changes. Skylights, gutters and rotten decking are not included.
Line the quotes up side by side: layers removed, underlayment type, ice-barrier coverage, flashing, ventilation and the decking price. The lowest bid often leaves one of those out.
DC Climate and Roof Wear
Climate Region 3 on the map below covers the District. Average winter highs run about 43°F, overnight lows about 26°F, and summer afternoons about 89°F. What that means for materials and installation in the District:
Freeze-thaw cycles. Water that seeps into a cracked shingle or an open seam freezes at night and widens the gap. Over many winters, small openings become leaks. Ice barrier at the eaves is inexpensive protection.
Algae streaks. The dark stains on many roofs here are algae that thrive in humid air. Algae-resistant shingles, made with copper-treated granules, stay clean much longer.
Many older attached homes have flat or nearly flat roofs, which take a membrane instead of shingles.
Where Shingles Live Longest: the Climate Bell
Asphalt life peaks in the moderate middle (Region 3) and falls toward BOTH ends of the map above - cold regions destroy shingles with ice dams, hot ones bake them. Note the middle columns: shingles marketed as “lifetime” are good for about 25 real-world years at best - District of Columbia is Region 3. Hover any column.
low pitch holds snow and ice - it costs the most years in cold regions
Planning figures from our climate model, for ventilation-correct installs - a baked, unvented attic can take years off any column. Pitch adjusts the asphalt columns only; metal sheds snow at any sane pitch.

Is Metal Worth It in Washington, DC?
Most metal bids in Washington, DC fall into one of the types below. Each line is priced for a typical 2,230 sq. ft. single-story house, the same way our metal roof calculator does it.
- Standing seam: $37,580 to $57,290. This is the classic metal roof: smooth vertical panels, fasteners tucked under the seam. It suits simple roof shapes and owners who plan to stay. Over architectural shingles, expect about $28,080 more.
- Steel shingles: $28,190 to $42,980. Aluminum shingles: $31,180 to $47,520. Small metal panels with a shingle or tile profile. They go on much like shingles, so hips and dormers are easier than with long panels. Pick aluminum near the ocean and steel inland.
- Stone-coated steel: $38,380 to $58,500. Steel tiles with a coat of stone granules. They are quiet in the rain, hard to dent, and look like tile or shake from the street.
- Copper: custom quote only. A copper roof is hand work by a sheet-metal specialist, and it is priced far above standing seam. It never needs paint and weathers to a green patina. Few homes cover the whole roof with it; dormers and entry roofs are the usual places.
Ice dams are the bigger risk, and metal stops most of them by shedding snow before it can refreeze. A reflective finish then helps through the hot weeks; copper weathers dark and does not.
Metal pays off for long-term owners. If a move is likely within a few years, architectural shingles usually give better value. The metal roof calculator prices each panel style separately.

Pricing Low-Slope Roofs in Washington, DC
Porches, additions, garages and some whole houses have roofs too flat for shingles; they get a membrane. Priced on the full 2,230 sq. ft. footprint in Washington, DC:
- EPDM rubber: $19,360 to $25,140. Synthetic rubber, usually black, laid in wide sheets with glued or taped seams. It shrugs off hail and hard frost and is easy to patch, so it suits garages, porches and roofs nobody sees.
- TPO, 60-mil: $16,660 to $21,640. Most roofers reach for TPO first today. It is white, light, and the seams are melted together rather than glued. Thicker sheets last longer, so compare the mil rating on each bid.
- PVC, 60-mil: $20,150 to $26,170. It looks like TPO but has a longer service record, and it holds up better where water sits or oils land. Choose it for a busy roof deck or a spot that never drains well.
TPO is the budget choice on this roof, and PVC sits at the top of the range. Each figure covers new polyiso board under the membrane and stripping the existing layer. Small flat areas cost more per square foot, since edges, flashing and setup barely shrink. Make sure a new flat roof drains completely; trapped water and winter freezes are a bad combination. Need another membrane or insulation level? The flat roof calculator prices it.
Plan for winter first: welded seams and clear drains. A white membrane is still worth it over rooms that get hot in July.
Roofing Bids in Washington, DC
The District prices as one dense city market, so bids tend toward the upper half of the ranges above. Attached row homes make membrane roofing as common as shingles here, and permit parking, tight alleys and limited dumpster space all add labor time that suburban jobs avoid.

Roof Replacement FAQ: Washington, DC
When does a home policy pay for roofing?
Policies pay for sudden events, not aging. Check whether yours pays replacement cost or depreciated value; on a $13,110 to $19,980 roof, that choice decides who pays most of the bill.
How many squares is my roof?
Take the footprint (2,230 sq. ft. here) and adjust for pitch (5/12): about 25.2 squares, or 2,520 sq. ft., counting overhang and waste. Get the square count on every quote.
Is a roofing permit required in the District?
Usually. Permit rules are set locally, and most require one for a complete re-roof. A licensed roofer pulls it in their own name.
What is the usual timeline for a re-roof?
A typical 25.2-square asphalt job takes from one day to a few, depending on layers, pitch and weather. Metal and cut-up roofs take longer. Any section left open overnight should be covered.
