Roofing in Napa

A Napa TPO project generated specific questions about retained foam, new decking and insulation board, then additional wood work before closeout. The useful lesson is to identify each layer and keep construction work separate from the record of inspection approval.

Permit fee planning
Napa’s July 1, 2026 reroof fee is $392 for the first 20 squares, plus $184 for each additional 10 squares. One square is 100 square feet. These are base components; applicable review and other charges increase the final assessment.

Inspections

Inspections and booking

  1. Deck and sheathing — Confirm whether Napa has assigned Roof Nail, code 130, to your reroof. Applicable roof/shear-nailing work must remain exposed until approval is recorded on the job card; ask specifically about retained decking and wood repairs.
  2. In-progress — Before installing underlayment, flashing or roofing, confirm any intermediate checks on Napa’s issued inspection card. Keep each required inspection area exposed until approved.
  3. Final closeout — Request Final Building, code 999, after the work and all applicable departmental finals are complete. Keep the final documents on site and confirm the energy paperwork required for your roof.
  4. Scheduling — Request at least 24 hours ahead through eTRAKiT or automated line 707-257-1063. Monday–Friday except city holidays; AM 8–noon or PM noon–4. City page says narrower windows and en-route calls are unavailable.

Local roofing decisions

Which layers were staying, and which were new?

During an August 2026 Napa TPO project, the homeowner asked whether an added foam layer was still needed because existing foam was already present. The project included new structural roof decking, wood repair, FR-10 and TPO. The homeowner separately confirmed that a half-inch insulation-board layer remained in scope. Those messages show why the layers needed to be identified individually rather than treated as interchangeable.

For another low-slope proposal, ask the contractor to describe the assembly from the retained surface to the finished membrane. Mark what stays, what is removed and which layers are new. If a change is proposed, the written revision should identify the affected layer and how it relates to the rest of the scope. That makes the comparison more useful than a single description such as “new flat roof.”

The recorded half-inch board describes this project’s discussion. Select insulation thickness and the approved assembly for the particular Napa roof. The project’s design and permit must establish those requirements.

How did the wood corrections affect roof closeout?

The Napa job record documents damaged rafter repairs, added supporting rafters and reinstatement and welding of the TPO membrane after the structural work. Related correspondence records an inspector’s request for additional underlying wood work and supporting photographs before closeout. ARS later reported final approval on August 29–30. That final approval was reported by ARS; confirm closeout on the actual permit.

The sequence is useful for planning: the supporting wood and its documentation needed attention before the roof was treated as ready for closeout. For a new project, keep the correction request, agreed repairs and completion documentation together. Confirm what the inspector needs to see before the membrane conceals it, and obtain the applicable approval rather than treating a construction invoice as the permit’s final record.

This example describes how one project proceeded. Other TPO roofs may need different repairs and inspection stages. The issued card and any actual corrections determine the holds.

A recorded Napa job required wood-stage reinspection after corrections. Check the actual permit card or portal for the required reinspection approval.
