The honest answer is that it depends on where your house sits and on how much of the system changes, and the only office that can answer it for your address is your local building department. That is not a dodge. It is how permitting works here, because it is handled locally rather than once for the whole state.
So this article will not guess your answer. It will turn the solar panel permit reinstall question into one you can ask properly, and understand the reply to, in a single phone call before the panels ever come off.
If you are mid-reroof in Greeley, Evans, Windsor or anywhere in Weld or Larimer County and nobody has raised permitting yet, raise it now. Call (970) 286-3417 and we will put the paperwork question in writing with your estimate.
Why two houses two miles apart get different answers
Northern Colorado is a patchwork of building departments. A house inside Greeley city limits answers to one. A house in Evans answers to another. Windsor, Johnstown, Eaton, Firestone and Fort Lupton are each their own jurisdiction, and a home on unincorporated county land answers to the county rather than to the nearest town.
That last one surprises people. Your mailing address can carry a town’s name while the property itself sits outside that town’s limits, so the department your neighbor called may not be the one with jurisdiction over you.
Requirements get revised, too. A friend who reroofed a few years back and sailed through is telling you what was true at their address, on that date. A data point, not an answer.
The two permits homeowners keep mixing up
Almost every confused conversation here comes down to one thing. Two separate scopes of work are happening on your roof, and they do not travel under one piece of paper.
The first is the roof itself. Tearing off old shingles and installing new ones is roofing work, and that permit is the roofer’s to apply for, pay for and close out. When your roofer says “the permit is handled,” that is almost certainly the one they mean.
The second is anything touching the electrical side of your solar system. A detach means disconnecting it. A reset means fastening the racking back down, remounting the modules, remaking the connections and re-energizing. That is electrical work on your house, a different question with a different answer, often reviewed by a different office than the one that stamped the roofing permit.
That split is why the answers you get feel contradictory. Your roofer is telling the truth about their scope. It just is not your whole job, and our piece on whether roofers can remove solar panels themselves covers where the two trades divide.
What makes a solar panel permit reinstall more likely to need paperwork
The other thing that moves the answer is how much of the system changes. Departments think about it on a spectrum, from putting back what was already approved to installing something new.
At the light end is a true like-for-like reset. Same panel count, same modules, same racking, same mounting points, same roof planes, same inverter. Nothing about the approved system changes except that it spent a week on the ground.
It moves toward being treated as new work when any of this shifts:
- The panel count goes up or down, or you swap in different modules
- The layout changes, or the array moves to different roof planes
- Racking or mounting hardware is replaced with a different system
- The inverter, optimizers or microinverters are changed
- Conduit gets rerouted, or the service panel or a breaker changes
That matters most if you see the reroof as a chance to upgrade. Newer panels while the array is already down is a redesign, not a reset, so read what changes when you replace panels during a reroof first. Hail pushes people the same way, since a replacement module is rarely identical to the one it replaces.
Your utility runs on its own track entirely, with its own forms and timing, and we cover that in what happens to net metering after a solar reinstall.
Who should be pulling it, and the answer that should worry you
Permits get pulled by whoever does the work. The roofer applies for the roofing permit. The company handling the solar electrical work applies for anything covering that. You should be paying for permits inside a line item on an estimate, not filling out applications.
Here is the part worth attention. In a lot of places a homeowner can pull an owner-builder permit on their own house, so when a contractor suggests you pull the electrical permit yourself, it sounds like a helpful shortcut.
Look at what it does, though. Your name goes on the application, the work becomes yours in the eyes of the inspector, and anything raised at inspection comes back to you rather than to the person who held the wrenches. Ask why they cannot pull it themselves. A vague answer tells you plenty about who is about to stand on your roof. More on that in how to choose a solar detach and reset contractor.
A verbal promise about the panels is where most of this trouble starts. “We will take care of the solar” is not a scope, it is a sentence.
What an inspection is actually for
An inspection is not a quality review or a grade on your new roof. An inspector confirms the finished work matches the rules the permit was issued under, then signs it off so the permit can close.
On a reinstalled array, what gets checked generally falls into a few areas. How the racking is fastened to the structure, and how those penetrations are flashed. Whether the wiring and connections were remade properly. Whether labels and placards are present and legible. Whether disconnects are where they belong and can actually be reached.
The first one is what homeowners underestimate, and what the cheapest quote tends to skip. Every mount is a hole in a brand new roof, and flashing those holes correctly is slower than not doing it. A missing sign-off shows up on paper. A bad penetration shows up as a leak under the panels two seasons later.
The paper matters at one moment, and that is when you sell. An open or missing permit can surface when a buyer’s inspector, the title work or a lender asks questions, and closing one out later can mean undoing finished work to show what is underneath. Cheap to avoid on day one. Expensive at closing.
Ask before the array comes down, not after
Paperwork found late is one of the main reasons a system sits dark for weeks instead of days. Once the panels are off and the new roof is on, an unresolved permit question can freeze the reset until it clears, and by then everyone’s schedule has moved on. Our breakdown of how long a detach and reset actually takes shows how fast that gap widens.
The order that keeps you out of trouble is short:
- Confirm which building department has jurisdiction over your address before you book anything.
- Call that department and ask the question below, close to those words.
- Get the answer reflected in your written estimate, including who applies for what.
- Only then schedule the detach around the roofing date.
Describe the job the way the department thinks about it. Something close to this:
“I am having my roof replaced. I have an existing rooftop solar array that will be detached and reinstalled in the same configuration. What permits and inspections does that require, and who needs to apply for them?”
Then ask two follow-ups. Whether the answer changes if equipment is replaced during the work, and whether the electrical portion is inspected separately. Write down who you spoke with and the date. If you would rather have the solar side handled end to end, that is what our detach and reset service in Greeley is for.

FAQ
Does the roofing permit cover putting my solar panels back on?
Generally no. A roofing permit covers the roof work itself, which is the roofer’s scope and the roofer’s responsibility to apply for. Reattaching and reconnecting a solar array is separate work on the electrical side of your house and is treated as its own question in a lot of places. Ask your building department about both scopes rather than assuming one covers the other.
Do I still need paperwork if the panels go back exactly as they were?
That depends on your jurisdiction, and it is the one question your building department can answer and nobody else can. A true like-for-like reset, with the same panels, racking, layout and inverter returning to the same roof, sits at the lightest end of the range. Anything that changes about the system pushes it toward being reviewed as new work instead.
Can I pull the permit myself as the homeowner?
In many places a homeowner is allowed to pull a permit on their own home, so the option often exists. Whether you should is a different matter. Pulling it yourself puts your name on the application and shifts responsibility for the work onto you rather than onto the contractor doing it. If a contractor asks you to do this for electrical work, ask why they cannot.
What happens if solar was reinstalled without the right permit?
Nothing may happen for years, which is exactly why it gets ignored. The problem tends to appear when the house sells and a buyer’s inspector, the title company or a lender asks about open or missing permits. Resolving it after the fact can mean uncovering finished work to show an inspector what is underneath. Call your building department and ask how they handle it.
