Drip edge
Required — Residential/Light Commercial Re-roof Guidelines: "Drip Edge installation required on gutter and rake edges." About drip edge
Ice & water shield
Required — Re-roof guidelines: "Ice and water barrier shall be installed on all roofs." The Design Criteria table on the same page separately lists "Ice barrier requirement - Yes." Mid-Roof Inspection checklist confirms: "All ice and water shield shall be in place." About ice & water barrier
Mid-roof inspection
Required — "Mid-roof and Final Inspections required." Mid-roof inspection requirements: "Complete tear-off, all underlayment and flashing installed, and ZERO shingles installed... There shall be no shingles installed until the mid-roof inspection has been passed. A Mid-Roof with any shingles installed will be failed and all shingles removed for the re-inspection."
Impact-resistant roofing
Not required — Town of Frederick Ordinance No. 1408 — which repealed and replaced Chapter 18 (Building Regulations) of the Municipal Code and adopted the 2024 International Residential Code, effective March 1, 2026 — was reviewed in full, including the complete list of local IRC amendments at Sec. 18-3-20; it contains no impact-resistance, UL 2218 or Class 4 roofing requirement, and does not amend IRC Section R905.2.4. The town's roofing performance requirement is a wind requirement: amended Table R301.2(1) sets a 115 mph wind speed, and the Residential/Light Commercial Re-roof Guidelines state "Wind design: 115 mph, 3 second gust roofing materials shall be covered under warranty by the manufacturer." The 2025 Colorado Wildfire Resiliency Code adopted at Article VI is a fire-classification code, not an impact standard.
Repair permit threshold
"Any roof repair over 100 sf will require a complete re-roof of the structure. Roofs that do not exhibit immediate life, health, and safety concerns under the Town of Frederick Building Code and policies of the Town may be repairs without a permit, with like material, up to a total area of 100 square feet, at the discretion of the Town Building Official."
Wind design criteria
Design Criteria table: "Wind Speed - 115 MPH" and "Exposure - Assumed to be C unless location complies with definition." Topographic effects, special wind region, and windborne debris zone are not separately stated on this page. (The Re-roof Guidelines section separately notes "Wind design: 115 mph, 3 second gust roofing materials shall be covered under warranty by the manufacturer," consistent with the Design Criteria table value.)
Roof layer limit / recover
"All old layers to be removed per the 2024 International Residential Code (IRC), Chapter 9, Section R908."
Sales & use tax
6.9% combined (state 2.9% + Weld County 0%, no county sales tax + Frederick-Firestone Fire Protection District 0.5% + town 3.5%). State-collected; DOR lists a 3.5% use tax applying to motor vehicles and building materials.
