How much does a roof replacement cost on a 2,000 sq ft home in Washington?

Size in this model is roof surface. One roofing square is 100 sq ft of roof surface, and the typical job is 16 squares (1,600 sq ft of roof surface, not floor area). In this model, 2,000 sq ft means roof surface (20 squares). It is separate from the floor area of a home, and the model has no floor-area input. The cost-by-size table has no 2,000 sq ft row; its rows are 10 squares (1,000 sq ft of roof surface), 16 squares (1,600 sq ft of roof surface, not floor area), and 18 squares (1,800 sq ft of roof surface). Read as roof surface, 2,000 sq ft is 20 squares. The calculator already scales job cost by squares divided by 16, and 20 is inside the allowed range of 8 to 60, so these figures are that same scale, not a guess between table rows. At 20 squares in Washington, DC the all-in is $7,555 low, $12,297 typical, and $58,880 high. Those all-in figures add the model's rounded permit for the bands on this row. The official fees are $0, $0, and $0. The model rounds each to the nearest dollar before adding it, so the all-in uses $0 on the low, $0 on the typical, and $0 on the high. The permit is the official 12-A DCMR § 105.2 like-kind roofing exemption at $0. It is not rescaled when the roof size changes, and it is not a new fee for 20 squares. The nearest table rows are 10 squares (1,000 sq ft of roof surface) at $6,148 typical and 18 squares (1,800 sq ft of roof surface) at $11,067 typical. Listed assumed valuations on this row are $8,000, $12,000, and $22,000, and they do not create a DOB permit fee on the like-kind exempt path. Job cost is adjusted for local wages using the BLS construction-and-extraction mean of $32.76 per hour for the Washington-Arlington-Alexandria, DC-VA-MD-WV metro (May 2025), labor wage multiplier 1.043, applied to the official 55% labor share. The permit line is not adjusted for local wages.

How much does roof replacement cost per square in Washington?

Cost per square on this page is the all-in typical divided by the roof squares on that row. One square is 100 sq ft of roof surface, not floor area. The cost-by-size rows are 10 squares (1,000 sq ft of roof surface), 16 squares (1,600 sq ft of roof surface, not floor area), and 18 squares (1,800 sq ft of roof surface). The official typical permit fee is $0. The cost-by-size table shows that fee on each of those rows, because this permit is the official like-kind roofing exemption and is not rescaled when the roof size changes. At 16 squares (1,600 sq ft of roof surface, not floor area) in Washington, DC the all-in typical is $9,838, which is $614.88 per square after rounding to the nearest dollar. At 10 squares the all-in typical is $6,148, or $614.80 per square. At 18 squares the all-in typical is $11,067, or $614.83 per square. Those per-square figures are that division of the row. They are not a separate published rate.

Is $30,000 too much for a roof replacement in Washington?

At the model's typical 16 squares (1,600 sq ft of roof surface, not floor area) in Washington, DC, the all-in is $6,044 low, $9,838 typical, and $47,104 high. $30,000 is above that typical of $9,838. Published asphalt-shingle installed prices run $5,800 to $20,000, so $30,000 is above that band. The national high of $46,000 is the published broad high for steep or premium materials. Wage-indexed for Washington, that high is $47,104 at 16 squares. $30,000 is below that adjusted for local wages high and above the typical. On the typical path the same scale first reaches $30,000 at 49 squares ($30,128 typical), which is outside the about 13 to 18 squares this page uses for a typical house. The official permit on this row is $0 at a $12,000 valuation, $0 at $8,000, and $0 at $22,000. Those valuations are unused on the like-kind exempt path and do not create a DOB permit fee. $30,000 is above that listed high valuation, so this row does not invent a separate permit fee for a $30,000 project value. The all-in figures add the model's rounded typical permit of $0.

Do I need a permit to replace my roof in Washington?

On the official like-kind path, no. Department of Buildings (DOB) lists roofing and coping replaced in kind as work that does not require a building permit in Washington, DC, and the official typical fee is $0. Under 12-A DCMR § 105.2, that exemption does not apply to exterior work in a historic district or on a historically designated structure (§ 105.2.5) or to work in a Special Flood Hazard Area (§ 105.2.6). A change of roofing material is not in-kind. In those cases a permit is required and the alteration and repair formula applies: ($30 + 2% of construction value) × 1.10, plus the Green Building Fee of 0.13% of construction value × 1.10. On this row that permitted path is listed as extras only: $314.16 at $12,000 and $548.46 at $22,000. The cited source is DC DOB permit exemptions (12-A DCMR § 105.2) and Building Permit Fee Schedule, retrieved 2026-10-07. The model rounds the official $0 to $0 before adding it to the all-in estimate. Sources: https://dob.dc.gov/page/get-permit and https://dob.dc.gov/node/1620346.

Does the DC green building fee apply to a roof permit in Washington?

Only when a roof permit is actually required. The DOB Building Permit Fee Schedule lists, under alteration and repair, a Green Building Fee of 0.13% of construction value for construction valued $1,001 to $1 million, with the same 10% additional fee as the permit line, and it lists no residential exclusion. A like-kind roof outside a historic district and outside a Special Flood Hazard Area is exempt, so neither the permit fee nor the green fee applies and the official fees stay $0, $0, and $0. When a permit is required, the green fee is charged on the same construction value as the permit fee. At $12,000 that is $15.60 × 1.10 = $17.16 on top of ($30 + $240) × 1.10 = $297, for $314.16. At $22,000 it is $28.60 × 1.10 = $31.46 on top of $517, for $548.46. Those permitted-path totals are listed extras and are not added to the all-in estimate. Source: https://dob.dc.gov/node/1620346.
