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

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 San Francisco, CA the all-in is $9,284 low, $14,911 typical, and $70,183 high. Those all-in figures add the model's rounded permit for the bands on this row. The official fees are $320.00, $320.00, and $320.00. The model rounds each to the nearest dollar before adding it, so the all-in uses $320 on the low, $320 on the typical, and $320 on the high. The permit is the official flat re-roofing permit path: Table 1A-G single-family and duplex re-roofing is $320.00 flat. It is not rescaled when the roof size changes, and it is not a new fee for 20 squares. Documented 1,000 / 1,500 / 1,800 sf of roof surface does not change those fees. Other occupancies at $556 are a different line and are not the official fee band. The nearest table rows are 10 squares (1,000 sq ft of roof surface) at $7,615 typical and 18 squares (1,800 sq ft of roof surface) at $13,452 typical. Listed assumed valuations on this row are $8,000, $12,000, and $22,000, and they do not change those listed fees on this flat path. Job cost is adjusted for local wages using the BLS construction-and-extraction mean of $43.66 per hour for the San Francisco-Oakland-Fremont, CA metro (May 2025), labor wage multiplier 1.390, applied to the official 55% labor share. The permit line is not adjusted for local wages.

How much does roof replacement cost per square and per square foot in San Francisco?

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, so per square means per 100 sq ft. Cost per sq ft is that same all-in typical divided by the roof surface in sq ft (squares times 100). 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 $320.00. The cost-by-size table shows that fee on each of those rows, because this permit is a flat re-roofing permit path and is not rescaled when the roof size changes. At 16 squares (1,600 sq ft of roof surface, not floor area) in San Francisco, CA the all-in typical is $11,993, which is $749.56 per square (per 100 sq ft) after rounding to the nearest dollar, and $7.50 per sq ft after rounding to the cent. At 10 squares the all-in typical is $7,615, or $761.50 per square and $7.62 per sq ft. At 18 squares the all-in typical is $13,452, or $747.33 per square and $7.47 per sq ft. Those per-square and per-sq-ft figures are that division of the row. They are not a separate published rate, and they are not a permit fee.

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

At the model's typical 16 squares (1,600 sq ft of roof surface, not floor area) in San Francisco, CA, the all-in is $7,491 low, $11,993 typical, and $56,210 high. $30,000 is above that typical of $11,993. 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 San Francisco, that high is $56,210 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 41 squares ($30,231 typical), which is outside the about 13 to 18 squares this page uses for a typical house. The official permit on this row is $320.00 at a $12,000 valuation, $320.00 at $8,000, and $320.00 at $22,000. Those valuations are unused on this flat re-roofing permit path and do not change the official fees. $30,000 is above that listed high valuation, so this row does not list a separate permit fee for a $30,000 project value. The all-in figures add the model's rounded typical permit of $320. They do not look up a new Table 1A-G fee at $30,000.

Do I need a permit to replace my roof in San Francisco?

On the official path, yes, a permit is required for a like-for-like 1-2 family reroof in San Francisco, CA. San Francisco Department of Building Inspection (DBI) bills that work on Table 1A-G, the flat re-roofing permit path for single-family homes and duplexes. The official typical fee is $320.00. Low, typical, and high all use that same flat path, so the official fees are $320.00, $320.00, and $320.00. These totals are a City and County of San Francisco DBI permit, not Oakland and not Daly City. Like-for-like reroof of a 1-2 family building uses the Table 1A-G re-roofing permit, not Table 1A-A. Table 1A-A valuation is the wrong path for this job. Other occupancies use $556 on the same table, and that line is not the official fee band. Electrical and plumbing are not included. The pre-1979 R3 lead $5 surcharge is not assumed. The model rounds the official $320.00 to the nearest dollar ($320) before adding it to the all-in estimate. The cited source is SF DBI Table 1A-G Inspections, Surveys and Reports, effective July 12, 2026, retrieved 2026-09-01 (https://media.api.sf.gov/documents/Table_1A-G_-_Inspection_Survey_and_Reports_2026.pdf).

How is the $320.00 roof permit fee calculated in San Francisco?

The official typical fee is $320.00 on the flat re-roofing permit path. Walk the typical first. Table 1A-G single-family and duplex re-roofing is $320.00 flat. The official extra is Table 1A-G re-roofing, single-family/duplex at $320.00, and the official note is Included. Other occupancies $556. Low and high match that same $320.00 total because the path is flat, so the low fee is $320.00 and the high fee is $320.00. The $320.00 high is the same total as the $320.00 typical and is not added on top of it. Job valuation does not drive this fee. Roof area is not an input. Electrical and plumbing are not included. The pre-1979 R3 lead $5 surcharge is not assumed in the official band. This page does not invent technology fees, state surcharges, or plan-review add-ons. The model rounds those listed fees to $320, $320, and $320 before adding them to the all-in estimate.

Does a bigger roof job change the San Francisco roof permit fee?

No. A bigger roof job does not change the San Francisco roof permit fee. The path is a flat re-roofing permit path on Table 1A-G for single-family homes and duplexes. Job valuation does not drive this fee. Table 1A-A valuation is the wrong path for a like-for-like 1-2 family reroof. At $8,000 the official fee is $320.00. At $12,000 the official fee is $320.00. At $22,000 the official fee is $320.00. Those assumed valuations of $8,000 / $12,000 / $22,000 still produce $320.00 because the path is flat. The cost-by-size table adds those listed fees rounded to $320, $320, and $320. It does not compute a new permit for 16 squares or for 20 squares.

Does roof area change the San Francisco roof permit fee?

No. Roof area does not change the San Francisco roof permit fee. The path is flat. Documented 1,000 / 1,500 / 1,800 sf still produces $320.00. Roof area and job valuation are not inputs to this listed permit total. The official fees stay $320.00, $320.00, and $320.00 at the assumed valuations of $8,000 / $12,000 / $22,000. The cost-by-size table adds those listed fees rounded to $320, $320, and $320. It does not compute a new permit for 16 squares or for 20 squares.

What about other occupancies on the San Francisco re-roofing table?

Other occupancies use $556 on Table 1A-G. That $556 line is a different occupancy and is not the official fee band. The official band for single-family homes and duplexes is $320.00 / $320.00 / $320.00. The extra on this row is Table 1A-G re-roofing, single-family/duplex at $320.00, and the official note is Included. Other occupancies $556. The $556 figure is not used as the low fee, the typical fee, or the high fee. A like-for-like 1-2 family reroof stays on the $320.00 flat re-roofing permit path.
