The short answer
Yes. Castle Rock charges use tax on roofing materials, and a permit is required before you replace the roof.
The Town of Castle Rock's Building Use Tax page says anyone doing construction work that requires a Town building permit must pay Town building use tax on the cost of construction materials. The use tax is generally paid on the building permit when it is issued.
The rate is 5.2% of the estimated construction materials. That 5.2% is 4.2% Town use tax plus 1% Douglas County use tax. The Town estimates construction materials at 50% of the project's valuation.
Use tax is paid to the Town instead of sales tax to a vendor. To avoid paying both, show a copy of the active, valid building permit to the vendor when you buy materials. Purchases made before the permit is issued are not eligible for a refund if sales tax was also charged.
Re-roof checklist
What the Town requires on the roof itself.
A building permit is required before you replace the roof. Permits expire if no inspection is completed within 180 days of issuance or of the last approved inspection.
- 100% tear-off. Existing roof covering and underlayment must come off to expose the roof deck. Overlays are not permitted.
- Mid-roof inspection. Yes, it is required. The Town's FAQ says mid-roof inspections are scheduled when the roof is 100% dried in, with no fewer than five rows of roof covering installed and no more than 50% complete. The roof cannot be finished until that inspection is approved.
- Ice and water barrier. Required under the 2018 IRC tables the Town cites, except on detached accessory structures that do not contain conditioned floor area.
- Drip edge is required at eaves and rakes of shingle roofs (2018 IRC R905.2.8.5).
- A ladder must be provided by the permit holder for inspections. Town inspectors do not bring one.
- Wildfire rules may apply. Effective June 30, 2026, re-roof permits may also be subject to the Colorado Wildfire Resiliency Code, depending on the property's hazard classification. Check the Town's Colorado Wildfire Resiliency Map for your lot.
If the mid-roof inspection is missed, the Town describes two options: uncover 10% of each side and schedule the inspection (an $85 reinspection fee may apply), or submit an Alternative Method Request with a stamped engineer's or architect's letter. That letter does not guarantee acceptance; partial tear-off may still be required.
Inspections can be scheduled through eTRAKiT (before 6:30 a.m. for same day) or the inspection line at 303-660-1341 (before 3:30 p.m. for the next business day). Building questions: BuildingCounter@CRgov.com or 720-733-3527.

We do not list a flat building-permit fee here because we did not verify a current re-roof permit amount on the Town fee schedule. Use tax is separate from the permit fee. Confirm both when the permit is issued.
Who pulls the permit
If you hire a contractor, that contractor has to be registered with the Town and pull the permit.
The Town's residential permit page says contractors must have a valid license from a jurisdiction with an ICC-equivalent exam, insurance, and current registration with the Town of Castle Rock before applying. Residential roof (re-roof) applications go through eTRAKiT. A homeowner may obtain a permit only if they own and live in the home and are doing the work themselves, and they must submit a Homeowner Affidavit.
When Homey replaces the roof, we handle the Town permit and schedule the inspections. We present the active permit when materials are purchased so Town sales tax is not charged on top of the use tax already paid.

Does Castle Rock charge use tax on roofing materials, and what does the Town Re-Roof Checklist actually require?
Yes. The Town of Castle Rock Building Use Tax page says anyone doing construction work that requires a Town building permit must pay Town building use tax on construction materials. The published rate is 5.2% (4.2% Town plus 1% Douglas County) of estimated materials, and materials are estimated at 50% of the project's valuation. Use tax is generally paid with the permit. The Re-Roof Checklist requires a permit, 100% tear-off (no overlays), a mid-roof inspection when the roof is 100% dried in with at least five rows and no more than 50% complete, ice and water barrier except on detached unconditioned accessories, drip edge at eaves and rakes, and a ladder supplied by the permit holder. Permits expire if no inspection is completed within 180 days. Show the active permit to the vendor so you do not also pay sales tax.
How do I avoid paying both use tax and sales tax?
The Town says to present a copy of the active, valid building permit to the vendor when you buy materials. Purchases made before the permit is issued are not eligible for a refund if sales tax was also charged.
Is there a mid-roof inspection on a Castle Rock re-roof?
Yes. The Town's homeowner FAQ says mid-roof inspections are scheduled when the roof is 100% dried in, with no fewer than five rows of roof covering installed and no more than 50% complete. The roof cannot be finished until that inspection is approved. If it is missed, the Town describes uncovering 10% of each side (an $85 reinspection fee may apply) or submitting an Alternative Method Request with a stamped engineer's or architect's letter, which is not a guarantee of acceptance.
Do you list the building permit fee here?
No. We verified the 5.2% use tax on the Town's Building Use Tax page. We did not verify a current flat building-permit fee for a typical re-roof on the Town fee schedule, so we do not publish one. Confirm the permit fee when the permit is issued. Use tax is separate from that fee.
