Before the roof is one-quarter complete
Coordinate the in-process inspection while the work is still at the required stage. Waiting until everything is covered loses the point of an inspection during the work.

Gladstone Roofing Permits & Inspections
Gladstone requires a building permit for roofing and reroofing residential or commercial structures. Its published instructions also set an inspection during the work, before the roof is one-quarter complete.
Roof work and city inspections belong in one plan
A permit establishes the city’s project process; it does not define every physical roof detail. Use the rules below to understand removal, eave protection and inspection timing, then connect them to the actual replacement assembly.
- Use the answer
- Understand the work and its meaningful limits.
- Apply it to the roof
- Request a free inspection for the actual property.
Gladstone roofing permit requirements
The city’s roofing page answers the basic permit question directly. This guide was checked against the published city instructions on November 2, 2026.
- Residential and commercial structures
A building permit is required to roof or reroof a house or business. New roofs associated with new construction already covered by a valid building permit are the stated exception.
- Application information
The city lists a completed building-permit application and allows the Building Official to request more information. Proof of ownership is mentioned for a recently purchased property.
- The property’s jurisdiction
These are City of Gladstone instructions. A Gladstone mailing address or nearby neighborhood name alone does not settle municipal jurisdiction; the property location needs to be tied to the correct authority.
One layer and ice-barrier requirements
The city page lists the same one-layer and ice-barrier points under residential and commercial roofing. The project’s system details need to be resolved with the city.
| Published point | What it means for planning |
|---|---|
| Only one layer of roof covering | Plan removal when replacing an existing covering instead of assuming a second layer is allowed. |
| Ice-barrier protection | The published rule describes cemented underlayment layers or a self-adhering polymer-modified bitumen sheet. |
| Extent of the ice barrier | The city specifies protection from the lowest roof edges to at least 24 inches inside the exterior wall line. That is measured relative to the wall, not simply a fixed strip width at the eave. |
Inspections during roofing work
The roofing page lists both stages below. The commercial inspection page repeats the reroof sequence and describes its overall inspection list as a guideline, with additional inspections possible.
At completion
A final inspection is a separate stage. Project cleanup and contractor review do not replace the city’s inspection requirement.
Permit fees and project valuation
Gladstone bases the building permit fee on project value. Its linked fee schedule is a valuation table, not a flat roofing charge.
Plan the municipal cost separately
Project valuation
The value and scope used for the application determine how the city applies its table.
Payment at issue
The roofing page says the permit fee is due when the permit is issued.
Confirm the current project charge
The linked schedule is undated. The city should confirm its application to the actual roofing work and any additional charges.
The permit fee is separate from the installed roof price. This guide does not turn a valuation example into a project quote.
Roofing permit FAQs
Is the in-process inspection only for commercial reroofing?
The general roofing page lists an in-process inspection before one-quarter completion and a final inspection. The commercial inspection page separately repeats those stages for reroofing. Confirm the required sequence for the actual permit before roofing is covered.
Which codes does the city roofing page list?
The page currently lists the ICC 2021 Construction Code Series and the 2020 National Electric Code. Local amendments and the particular roof system still matter, so the project requirements need confirmation with Community Development.
