Roofing in Centennial has stricter reroof rules than many homeowners expect, and the city issues the permit directly through its Building Division. A reroof is a One-Stop Permit, but the field requirements are not casual: tear-off, ice barrier, drip edge, decking gaps, material limits, and mid-roof inspection all matter. Our crew plans Centennial roofs around what must be visible before the roof is covered.
Small Repairs Have a Permit Threshold
Centennial does not require a permit for roof repairs under 100 square feet. Repairs of 100 square feet or more require a permit. That threshold is important after wind or hail because a roof can move from repair work into permitted work quickly.
The city also says repairs exceeding 25% of the total roof area trigger a mandatory full tear-off and reroof. We evaluate the damaged area before treating the job as a patch. If the work crosses Centennial’s repair limit, the project needs to be planned as a reroof rather than a larger repair.
Centennial Requires Full Tear-Off
Centennial states that roof replacement must include removal of all existing roof coverings down to the deck. Overlay or re-cover work is not allowed, regardless of how many layers are already on the house. That is one of the city’s most important local roofing rules.
Full tear-off changes the build. The deck condition becomes visible, old fasteners and failed underlayment are removed, and the crew has to protect the home while the roof is open. We schedule labor, staging, and weather protection around that exposed phase because Centennial’s rules require the roof to be rebuilt from the deck up.
Underlayment, Drip Edge, and Decking Are Inspection Items
Centennial requires ice barrier underlayment on all roofs. The rule is unconditional, so we do not treat ice barrier as an optional upgrade or a detail limited to a particular roof edge. It is part of the permitted roof assembly.
Drip edge is required at all roof edges, and skip decking gaps must be ½ inch or less. Those details have to be addressed while the roof is open. Our crew checks decking gaps after tear-off, installs drip edge as part of the assembly, and keeps underlayment work visible for inspection documentation.
Material Rules Limit What Can Go Back On
Centennial explicitly prohibits used or harvested roofing materials. That means salvaged material cannot be used to complete a permitted roof replacement. The finished roof has to be built with acceptable new materials, not a mix of reused products from another project.
The city also points roofing design criteria to Centennial Municipal Code Sec. 18-2-30, Table R301.2(1), for climatic and geographic design criteria such as ground snow load, wind speed, and seismic design category. We treat material selection and installation as part of a local roof assembly, not just a generic shingle order.
Mid-Roof Inspection Shapes the Workday
Centennial requires a mid-roof inspection for all reroof permits, and the city allows that inspection to be satisfied by photo submission. This affects scheduling because the roof needs to be documented at the right stage. If everything is covered too quickly, the evidence the city needs may be gone.
Our crew builds the day around tear-off, deck review, drip edge, ice barrier, underlayment, and photo documentation before the roof is fully closed in. The permit may be issued quickly as a One-Stop Permit, with a 1 business day review path, but the field sequence still has to respect Centennial’s inspection requirement.
How We Sequence a Centennial Reroof
The sequence starts with deciding whether the work is below the repair threshold, a permitted repair, or a full reroof. For a reroof, we pull the One-Stop Permit, remove existing coverings to the deck, correct decking issues, install required edge and underlayment components, document the mid-roof condition, finish the roof covering, and close out final requirements.
Centennial’s local roofing rules reward disciplined staging. Full tear-off, unconditional ice barrier, decking-gap limits, drip edge at every roof edge, and the mid-roof inspection all happen before the roof looks finished from the street. We plan those steps before materials arrive so the job passes through the city process without covering required inspection points too early.
