Colorado Roofing and Siding Permit Requirements by Jurisdiction

Colorado does not have one universal local roofing permit process. The city, county or regional building authority that has jurisdiction over the property determines the permit and inspection process.

The table below covers the major population centers and roofing markets from Colorado Springs north through Fort Collins and west along the I-70 mountain corridor through Vail, including many surrounding jurisdictions.

How to Read the Table

• Yes means the jurisdiction publishes a permit requirement or dedicated permit category for that work.
• No means the jurisdiction publishes an exemption for that work or circumstance.
• Specialty/System Dependent means a standard asphalt roof may not require a mid-roof inspection, while tile, metal, low-slope, batten or another specialty system may.
• Yes, All Reroofs means the jurisdiction specifically requires a mid-roof inspection on ordinary reroof permits.
• Verify means the jurisdiction clearly requires the roofing permit but its currently published public guidance does not clearly establish one universal rule for that particular inspection or siding situation.

I-70 and Mountain Corridor

Important Differences Contractors Should Know

The table makes one thing clear: "Colorado requires a permit" is not enough information to properly manage a roofing job.

A contractor needs to know the actual jurisdiction and its inspection sequence before material is installed.

For example:

Colorado Springs

Colorado Springs uses the Pikes Peak Regional Building Department, not a stand-alone City of Colorado Springs building department for normal roofing permits.

PPRBD currently identifies:

• Asphalt reroof: Roofing final inspection
• Tile reroof: Tile-roof inspection plus roofing final inspection
• Reroof, siding and stucco: Permit categories that do not require the ordinary plan-review process

PPRBD also serves El Paso County, Fountain, Woodland Park, Manitou Springs, Monument, Green Mountain Falls, Palmer Lake and Calhan.

Castle Rock

Castle Rock requires a roofing permit before replacing the roof.

The Town also requires a mid-roof inspection. Its current guidance even establishes a procedure for a contractor that accidentally covers the roof before the mid-roof inspection. The contractor may be required to uncover approximately 10% of separate roof fields/facets or pursue an alternative-method request supported by a Colorado architect or engineer.

That is a significant operational issue for roofing contractors. 

Centennial

Centennial is another jurisdiction contractors should flag in their production system.

Mid-roof inspections are required for all reroof permits.

For a mid-roof inspection, Centennial directs contractors to have the tear-off completed, underlayment installed and approximately 25% to 75% of the new roofing installed. Mid-roof and final inspections may also be available through the City's photo-inspection procedure. 

Jefferson County

Unincorporated Jefferson County has a particularly important inspection rule.

A mid-roof inspection is required when the roof is at least 10% but no more than 25% complete.

Roof repair exceeding two roofing squares also requires a permit. 

This means contractors should not apply Arvada, Lakewood or Golden procedures to an unincorporated Jefferson County property simply because the mailing address says one of those cities.

Arvada

Arvada requires permits and inspections for residential and commercial roof replacement.

For residential roofing:

• Standard asphalt roofing generally does not require a mid-roof inspection.
• Low-slope roofs require one.
• Tile roofs require one.
• Specialty roofs and special conditions can require one.
• Every reroof permit requires a final roofing inspection.

Repairs totaling no more than 100 sq. ft. per year are considered maintenance and do not require a reroof permit. 

Arvada also specifically requires permits for replacement siding. 

Thornton

Thornton currently has one of the more unusual roofing inspection systems in Colorado.

The City requires a mid-roof inspection, but as of its August 18, 2025 published procedure, the mid-roof inspection is completed through photographs submitted to the Building Division.

The contractor must wait for approval before closing the roof.

The final roofing inspection is performed virtually. 

Broomfield

Broomfield also requires a mid-roof inspection.

Its March 2026 reroof permit application states:

• Mid-roof inspection when the roof is approximately 25% to 50% complete
• Final inspection when roofing is completed

Broomfield also expressly allows an owner of a primary residence to obtain a homeowner permit for work they are personally performing. If the homeowner hires a contractor, that contractor must be licensed by Broomfield. 

Loveland

Loveland changed its roofing procedure effective January 1, 2026.

A roofing repair under 100 sq. ft. does not require a permit. Larger repairs and reroofs do.

Loveland's mid-roof verification is unusual because the contractor takes photographs rather than having a city inspector physically visit the property for that stage. The documentation includes underlayment, sheathing replacement where applicable, ice barrier, flashing and nailing information.

The City then requires a final roofing inspection. 

Breckenridge

Mountain jurisdictions deserve their own attention because snow, wildfire and Class A roofing requirements become substantially more important.

Breckenridge's current reroof requirements state that most roofing projects have a minimum of two inspections:

1. Underlayment and flashing inspection
2. Final building inspection

Breckenridge also requires Class A roof coverings for new construction, additions and reroofs. 

Vail

Vail treats single-family and duplex reroofs as expedited permits.

Vail also adds another layer that contractors working exclusively on the Front Range may not expect. Exterior work must obtain Design Review Board approval before the building-permit process.

That means the contractor should not assume that securing the reroof building permit is the only approval necessary. 

One Mailing Address Can Have Different Building Jurisdictions

One of the easiest permit mistakes in Colorado is identifying the jurisdiction by the city printed on the mailing address.

That is not reliable.

For example, a property may have a:

• Littleton mailing address but actually be in unincorporated Arapahoe County
• Golden mailing address but be in unincorporated Jefferson County
• Parker mailing address but be in unincorporated Douglas County
• Loveland mailing address but fall under Larimer County
• Silverthorne or Frisco mailing address but fall under Summit County
• Eagle-area address but fall under Eagle County rather than the Town of Eagle

Those distinctions can completely change the inspection requirements.

The property address should therefore be checked against the actual Authority Having Jurisdiction before a roofing permit is pulled or production is scheduled.

Recommended Roofing Contractor Permit Workflow

For every Colorado roofing project, the production file should identify:

1. Property address
2. Authority Having Jurisdiction
3. Roof permit required?
4. Siding permit required?
5. Permit number
6. Permit holder
7. Roofing system
8. Deck/sheathing inspection required?
9. Mid-roof or underlayment inspection required?
10. When the roof must be stopped for inspection
11. Final inspection required?
12. Inspection approval date
13. Final permit status

The most dangerous assumption for a roofing contractor is:

"We don't normally need a mid-roof inspection."

That statement may be true five miles away and completely wrong on the current job.

Castle Rock, Centennial, Jefferson County, Thornton, Broomfield, Loveland and Breckenridge alone demonstrate how dramatically roofing inspection procedures can change between Colorado jurisdictions.

Why Are Roofing Permits Required?

A roofing permit gives the local building department an opportunity to verify that the roof is being installed according to the adopted building code and local amendments.

An inspector may evaluate items such as:

• Proper roof covering
• Manufacturer installation requirements
• Fastener type and placement
• Underlayment
• Flashing
• Roof penetrations
• Roof-to-wall intersections
• Drip edge
• Ventilation
• Roof decking where exposed or replaced
• Low-slope roofing requirements
• Tile or metal attachment
• Wind-resistance requirements
• Fire classification
• Ice-barrier requirements where applicable

The permit also creates a public record showing that the work was performed under a building permit and that required inspections were completed.

That can become important when the property is sold.

What Is a Mid-Roof Inspection?

A mid-roof inspection occurs after certain components of the roofing system have been installed but before they are concealed by the finished roof covering.

Not every Colorado jurisdiction requires one for every roof.

In fact, standard asphalt-shingle reroofs frequently require only a final inspection. Mid-roof inspections become much more common when dealing with:

• Concrete or clay tile
• Batten-mounted roofing
• Certain metal roofing systems
• Low-slope roofing
• Specialty roofing assemblies
• Unusual installation conditions

For example, Westminster specifically states that no mid-roof inspection is required for an asphalt-shingle installation, while batten-type applications require one. 

Arvada similarly requires mid-roof inspections for low-slope, tile and other special roofing situations. 

Douglas County requires a mid-roof inspection when the roofing material requires battens. 

This is why a contractor should determine the inspection sequence before starting the installation. If an inspection is required before a component is concealed and the contractor covers it first, portions of the roof may have to be exposed so the inspector can verify the installation.

What Is a Roof-Deck Inspection?

A roof-deck inspection is different from a final roofing inspection.

If deteriorated decking is removed or substantial new decking is installed, some jurisdictions may require the decking to remain exposed until it has been inspected.

Westminster, for example, states that when new decking is required or provided, a roof-decking inspection is required before roof coverings are installed. 

Contractors should therefore be careful about automatically redecking a roof and immediately installing underlayment and shingles. The local jurisdiction should first be checked for any required deck or sheathing inspection.

Do Small Roof Repairs Require a Permit?

Sometimes they do not.

Several Colorado jurisdictions provide an exemption for small repairs.

For example:

• Boulder: roofing work involving more than one square, or 100 sq. ft., requires a permit. 
• Arvada: replacement of up to 100 sq. ft. per year is treated as maintenance and does not require a reroof permit. 
• Lakewood: repairs under 100 sq. ft. do not require a roofing permit under its published residential guidance. 
• Englewood: roofing or siding repair of 100 sq. ft. or less does not require a permit. 
• Adams County: minor roofing repair of one square or less is listed as exempt.
• Denver: the threshold is different. Repairs exceeding 10% of the roof area or two roofing squares, whichever is smaller, require a roofing permit. 

This demonstrates why contractors should not assume that a rule used in one Denver-area jurisdiction applies to the next city.

Are Siding Permits Required in Colorado?

Frequently, yes.

Siding can be regulated as an exterior wall covering because improper installation can affect weather protection, flashing, moisture management, and the building envelope.

Denver includes exterior wall coverings within its roofing and siding permit category. 

Arvada specifically states that permits are required for replacement siding on residential homes. 

Westminster lists siding and stucco, other than minor repair, as work requiring a permit. Minor siding repairs under 100 sq. ft. are exempt. 

Adams County also lists siding and stucco as permit-required projects.

Boulder maintains a dedicated siding permit category.

Siding projects can become more complicated when the contractor discovers damaged sheathing, structural damage, missing weather-resistant barriers or improperly flashed windows and doors.

What Is a Homeowner Permit?

A homeowner permit, sometimes called an owner-builder or owner-occupier permit, allows a qualifying property owner to obtain a permit and perform certain construction work themselves instead of hiring a licensed contractor to act as the permit holder.

However, a homeowner permit is not a way for an unlicensed contractor to perform work under the homeowner's name.

The rules vary substantially by jurisdiction.

For example, Englewood allows a homeowner to reroof their own house when they own and occupy it. If a roofing contractor is hired, Englewood states that the contractor must hold the appropriate license and pull the permit.

Lakewood similarly states that homeowners may obtain a reroof permit on an owner-occupied single-family home when they are performing the work themselves. 

Arvada allows qualifying owners to perform certain work themselves and specifically includes reroofing and siding among the types of work that an owner can perform under its homeowner provisions. 

Denver has more detailed owner-occupier requirements. Its current policy defines an owner-occupier as the natural person who owns and occupies the qualifying single-unit dwelling and establishes specific procedures and restrictions for homeowner permits.

How Does a Homeowner Permit Work?

The general process is:

1. Determine the actual building jurisdiction.
2. Confirm that the homeowner is eligible to pull the permit.
3. Submit the permit application and required project information.
4. Pay the applicable permit fees.
5. Perform the work in compliance with the adopted building code, local amendments and manufacturer requirements.
6. Schedule any required intermediate inspections before work is concealed.
7. Schedule the final inspection.
8. Correct any deficiencies identified by the inspector.
9. Obtain final approval and make sure the permit is closed.

The homeowner becomes responsible for ensuring the permitted work complies with the applicable requirements.

Should a Homeowner Pull the Permit for a Roofing Contractor?

The roofing contractor should pull the roofing permit when the contractor is actually performing the work, particularly when the jurisdiction requires contractors to be licensed or registered.

A homeowner should be cautious if a contractor says:

"Just pull a homeowner permit for us."

That arrangement may shift responsibility toward the homeowner and may violate the jurisdiction's homeowner-permit rules.

A legitimate homeowner permit is intended for circumstances permitted by the local building authority, typically involving the homeowner actually performing or directly controlling qualifying work.

What Happens If a Roof Is Replaced Without a Permit?

The consequences vary by jurisdiction and circumstances, but possible problems include:

• Stop-work orders
• After-the-fact permits
• Additional permit fees
• Required inspections
• Opening or removing completed work for inspection
• Code corrections
• Contractor licensing consequences
• Problems documenting the work when the property is sold
• Difficulty demonstrating that the roof passed a municipal inspection

A permit is not merely a receipt. The important part is closing the permit by completing the required inspections.

Frequently Asked Questions About Colorado Roofing Permits

Does Colorado require a roofing permit statewide?

There is not one uniform statewide reroof permit process for every property. Local cities, towns and counties generally administer building permits and inspections. Requirements therefore depend on the authority having jurisdiction over the property.

Does Denver require a roofing permit?

Yes, for qualifying roofing work. Denver states that repairs exceeding 10% of the roof square footage or two roofing squares, whichever is smaller, require a roof permit.

Does a small roofing repair require a permit?

It depends on the jurisdiction. Many Colorado jurisdictions exempt approximately one roofing square, or 100 sq. ft., of minor repair. Denver uses a different threshold.

Does siding require a permit?

In many Colorado jurisdictions, yes. Denver, Boulder, Arvada, Westminster, Adams County and Jefferson County all have permitting provisions covering siding or re-siding. 

Is a mid-roof inspection always required?

No.

Standard asphalt-shingle reroofs often do not require a mid-roof inspection. Tile, batten-mounted roofing, low-slope roofs and specialty systems are considerably more likely to require one.

Does a roof need a final inspection?

If a roofing permit has been issued, a final roofing inspection is normally required to close the permit. For example, Englewood, Lakewood, Arvada, Fort Collins and Westminster expressly require final inspections under their published reroof guidance. 

Can a homeowner pull their own roofing permit?

Often, yes, but eligibility depends on the jurisdiction. Some jurisdictions limit homeowner permits to owner-occupied properties or impose other conditions.

Can my roofer have me pull a homeowner permit and then perform the work?

Do not assume this is permitted. If a professional roofing contractor is performing the project, the contractor may be required to hold the appropriate local license or registration and obtain the permit themselves.

Do I need a permit before tearing off the old roof?

Where a roofing permit is required, it should generally be issued before work begins. Boulder expressly states that the roofing permit must be obtained before work starts, including tear-off.

What if my property is in an HOA?

A building permit and HOA approval are separate issues. Receiving a building permit does not automatically mean the roof or siding complies with HOA architectural requirements.

What if the property is historic?

Additional requirements may apply. Denver requires Landmark Preservation approval for roofing and siding work on individual landmarks and buildings within historic districts. Boulder similarly requires a Landmark Alteration Certificate for applicable exterior work on designated properties.

What if I am changing from asphalt shingles to tile?

Contact the jurisdiction before ordering materials. Tile is substantially heavier than asphalt shingles and may trigger structural documentation, engineering and additional inspection requirements. Arapahoe County, for example, requires an engineer's letter when replacing existing metal or asphalt roofing with concrete or clay tile. 

Who is responsible for scheduling the inspection?

The permit holder is generally responsible for making sure all required inspections are requested and completed. If a contractor pulled the permit, homeowners should still verify that the permit ultimately reaches a final or completed status.

The Bottom Line

For most full roof replacements in Colorado's major municipalities and populated counties, expect a roofing permit to be required.

Siding permits are also common, but the requirements vary more by jurisdiction and project scope.

The biggest variation involves mid-roof inspections. A conventional asphalt-shingle reroof may require only a final inspection in one jurisdiction, while tile, metal, batten-mounted, low-slope or specialty systems can require an inspection before the finished roofing material is installed.

Before beginning a roofing or siding project, confirm four things with the authority having jurisdiction:

1. Is a permit required?
2. Who is legally allowed to pull it?
3. Is a mid-roof, deck, lath, weather-barrier or other concealed-work inspection required?
4. What inspection is required to close the permit?

Permit requirements change as cities and counties adopt new building codes and local amendments. Always verify current requirements with the applicable building department before beginning construction.

Permit requirements and inspection procedures are subject to change. Information should be verified against the applicable building authority before beginning each project. Table researched and updated August 24, 2026.
