What we assumed

We price Roof replacement in Boston, MA at 16 squares (1,600 sq ft of roof surface, not floor area).

For the permit line we assumed a covering-only reroof on the official short-form schedule, with valuations of $8,000 low, $12,000 typical, and $22,000 high, so the low fee is $100, the typical fee is $140, and the high fee is $240. Each total is the $20 short-form primary plus $10 per $1,000 of estimated cost. Structural sheathing/framing is long-form ($50 + $10 per $1,000) and is not the official total. Full arithmetic is in the calculation note on this page. The official typical project value is $12,000.

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

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 Boston, MA the all-in is $8,569 low, $13,926 typical, and $66,250 high. Those all-in figures add the model's rounded permit for the valuation bands on this row. The official fees are $100, $140, and $240. The model rounds each to the nearest dollar before adding it, so the all-in uses $100 on the low, $140 on the typical, and $240 on the high. The permit is based on project value, so it is not rescaled when the roof size changes, and it is not a new fee for 20 squares. The nearest table rows are 18 squares (1,800 sq ft of roof surface) at $12,547 typical and 16 squares (1,600 sq ft of roof surface, not floor area) at $11,169 typical.

How much does roof replacement cost per square in Boston?

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 $140. The cost-by-size table shows that fee on each of those rows, because this permit is based on project value and is not rescaled when the roof size changes. At 16 squares (1,600 sq ft of roof surface, not floor area) in Boston, MA the all-in typical is $11,169, which is $698.06 per square after rounding to the nearest dollar. At 10 squares the all-in typical is $7,033, or $703.30 per square. At 18 squares the all-in typical is $12,547, or $697.06 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 Boston?

At the model's typical 16 squares (1,600 sq ft of roof surface, not floor area) in Boston, MA, the all-in is $6,875 low, $11,169 typical, and $53,048 high. $30,000 is above that typical of $11,169. 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 Boston, that high is $53,048 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 44 squares ($30,469 typical), which is outside the about 13 to 18 squares this page uses for a typical house. The official permit on this row is $140 at a $12,000 valuation, $100 at $8,000, and $240 at $22,000. $30,000 is above that listed high valuation, so this row does not list a permit fee for a $30,000 project value. The all-in figures add the model's rounded typical permit of $140. They do not look up a new fee at $30,000.

What do Boston roof permit fee bands cost on the short-form schedule?

The official fee bands are $100 low, $140 typical, and $240 high on the short-form schedule. Each band is the $20 short-form primary plus $10 per $1,000 of estimated cost at the official valuations of $8,000, $12,000, and $22,000. The $1,000 count uses ceil when the estimated cost is not a round thousand; these listed valuations are each a round thousand, so ceil does not change the count. Low: $8,000 / $1,000 = 8, and 8 × $10 = $80, then $20 + $80 = $100. Typical: $12,000 / $1,000 = 12, and 12 × $10 = $120, then $20 + $120 = $140. High: $22,000 / $1,000 = 22, and 22 × $10 = $220, then $20 + $220 = $240. The official extras are the $20 short-form primary and the $120 per-$1,000 line at $12,000, and both are included in the $140 typical. Structural sheathing/framing is long-form ($50 + $10 per $1,000). On that alternate at $12,000 the total would be $170, and that $170 is not the typical fee.
