How to apply in Jefferson County
In Jefferson County, a residential reroof permit application is lighter than for structural work: you state whether the scope is a full tear-off (roof replacement) or an overlay (roof recover), describe the covering material and its manufacturer instructions, and note the condition of the existing deck, since those facts determine which code path applies.
What most roof replacement permit applications include:
- State on the application whether the job is a roof replacement, which strips all existing layers down to the bare deck, or a roof recover, which leaves the old covering in place under specific conditions, since the two scopes are governed differently (IRC R908.3).
- For Jefferson County, a recover is only an option where the new covering follows the roof covering manufacturer's approved instructions or is a self-supporting system, such as standing-seam metal, that does not rely on the existing roof for support (IRC R908.3.1).
- Full tear-off must be scoped on the application instead of a recover when the existing roof is water soaked or deteriorated, is slate, clay, cement, or asbestos-cement tile, or already carries two or more layers of roof covering (IRC R908.3.1.1).
- For Jefferson County, the materials and installation methods described on the application must comply with the reroofing requirements of the roof-assemblies chapter (IRC R908.1).
- If the scope reuses existing slate, clay, or cement tile, damaged or broken pieces cannot be listed for reinstallation, and any rusted or deteriorated flashings, edgings, outlets, or vents uncovered during tear-off must be scoped for replacement (IRC R908.5).

Inspections and closing out your permit
In Jefferson County, most residential reroofs get two to three field inspections keyed to the scope of work: a deck or nailing check when sheathing is exposed or replaced, a final on the completed covering and flashings, and in some high-wind regions a dedicated check of mitigation measures added during tear-off.
- In Jefferson County: where the covering is fully removed and the sheathing is exposed, replaced, or added, inspectors check the deck and its nailing before any new roofing goes down, since the structural framework must be able to carry the new covering's loads (IRC R908.2).
- In Jefferson County: an overlay is only approved where it meets one of the code's listed recover conditions, such as installation in accordance with the covering manufacturer's approved instructions (IRC R908.3.1).
- In Jefferson County: flashings disturbed or replaced during the job are checked against the approved manufacturer's installation instructions, and metal flashing that will receive bituminous material must be primed before installation (IRC R908.6).
- In Jefferson County: a final inspection confirms the completed roof covering and its fasteners were installed as required for that material and per manufacturer instructions before the permit is closed (IRC R905).
- In Jefferson County: in some regions with strengthened wind provisions, reroofing an older single-family home also triggers inspection of supplemental deck-nailing and a secondary water barrier added during tear-off, on top of the base reroofing requirements (Florida Building Code, Residential R908.7 Mitigation).
- In Jefferson County: reinstalled existing slate, clay, or cement tile is checked against reuse limits at inspection, and any rusted, damaged, or deteriorated flashings, edgings, outlets, or vents found during tear-off must be replaced rather than reinstalled (IRC R908.5).
Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Jefferson County permit portal or by phone at 303-271-8260.

- Where do you apply for a roof replacement permit in Jefferson County?
- You can apply through the Jefferson County permit portal or contact the Jefferson County Division of Building Safety directly. The links are listed on this page.
- Can a homeowner pull a roof replacement permit themselves in Jefferson County?
- Under Colorado law (C.R.S. 12-115-116(2); C.R.S. 12-115-120(11)(c); C.R.S. 12-155-118(2); C.R.S. 12-155-120(11)(c)): Colorado's state electrical law has a homeowner exception: under C.R.S. 12-115-116(2), you do not need an electrician's license to do electrical work on your own property or residence, as long as all the work, other than maintenance or repair of existing systems, is inspected under the state law. The exception does not apply if the property is intended for sale or resale by someone in the construction or remodeling business, is rental property, or is generally open to the public. A homeowner performing work on the homeowner's home is a qualified applicant who may pull the state electrical permit under C.R.S. 12-115-120(11)(c), and plumbing mirrors this: C.R.S. 12-155-118(2) allows unlicensed plumbing work on your own property or residence with the same carve-outs, and C.R.S. 12-155-120(11)(c) lets a homeowner pull the state plumbing permit. The State Electrical and Plumbing Boards at DORA require that the homeowner personally perform the work, that it be inspected before cover and again at completion, and that it meet the National Electrical Code or the adopted plumbing codes. Colorado has no statewide general contractor license: Title 12 licenses electricians and plumbers at the state level, and general building contractors are licensed, if at all, by the individual city or county. Confirm how Jefferson County applies this before you apply.
