Pacheco records include tar-and-gravel removal, mixed flat and pitched roofing, and an enquiry about a low-slope Eichler-style home. The existing assembly and the County permit jurisdiction matter more than an informal location label.

Permit
Roof replacement permits in Pacheco
We pull it and schedule the inspections. It’s billed at the city’s actual cost, separate from the roof.
Permit authority
Contra Costa County Building Inspection; confirm the property’s jurisdiction.
Permit planning
ARS allows approximately one week for permits unless the department confirms a shorter route; issuance is not guaranteed.
Past ARS permit cost
A July 2026 Pacheco TPO reroof had a $436.20 County permit, including a $172 energy surcharge. The membrane roof and its assessed energy charge make this a different budgeting example from an asphalt-shingle reroof; your permit needs its own assessment.
Permit fee planning
County residential reroof base components are $150 plus $38 processing; surcharges and any separate local approvals add to the assessment.
From the Pacheco building department and our own project records. Content reviewed October 11, 2026; inspection guidance checked October 10, 2026. Fees change, so we confirm yours when we pull the permit.
Inspections
Inspections and booking
County inspection holds — County stages are 123 Roof/In Progress, preferably 25–75% complete for composition, then 120 Final after completion. Confirm deck, repair and nailing holds—including code 108—before covering, and obtain approval at every assigned stage; a separate deck visit depends on the permit.
Final closeout — Clear any County CalGreen hold through Green Halo before final; allow up to four business days. Confirm remaining conditions and roof access.
Booking — Book through County ePermits or 925-646-4108; confirm current deadlines and availability before tear-off.

Local roofing decisions
What was the homeowner deciding on the low-slope enquiry?
In a May 2026 Pacheco enquiry, the homeowner described the house as Eichler-style and asked about repair or possible replacement. ARS correspondence referenced a 1:12 slope and proposed discussing TPO alongside priorities such as appearance and energy performance. The size was the homeowner’s estimate, and historic status and completed work are not confirmed.
The useful first step was to identify the existing roof and the choices the owner wanted to compare. A low-slope assembly should be described as its own system, including its edges, openings and retained layers, rather than priced as though it were simply the main shingle roof. That is a planning consideration from the enquiry. It is not a blanket recommendation that TPO is the best option, or a claim that ARS has certified the home’s architectural history.
Why separate the layer count on the flat portion?
A September 2023 Pacheco replacement specifically called for removing a second layer over the flat portion. That area received FR-10 base material, clad perimeter metal and a 60-mil TPO membrane; the pitched portion used composition shingles. The same scope listed custom upper and lower fireplace saddles, a 32-watt attic fan and insulation.
This is a concrete example of why the demolition and replacement quantities should be organized by roof area. A price that includes an extra layer on the flat section covers different removal work from a one-layer assumption throughout. The proposal should also identify the membrane perimeter and where the systems meet. The recorded fan and insulation are additional scope items, not a promised performance result or standard inclusion for every Pacheco reroof.
What changed after the old tar-and-gravel roof was removed?
A July 2026 Pacheco replacement record documents tar-and-gravel tear-off, FR-10 underlayment, new clad edge metal and pipe jacks and vents. Deck and dry-rot repairs appear in the final invoice. Wood repair was part of that project. Another deck must be assessed when exposed.
For a homeowner comparing a reroof allowance, the relevant questions are how exposed repairs will be documented, how the price is handled when the scope changes, and when the inspector needs to see the work. The permit authority also needs to remain correct. Earlier team notes show a Pacheco job informally called Martinez; the permit address and County jurisdiction, rather than that shorthand, determine the applicable inspection process.
