Drip edge
Required About drip edge
Ice & water shield
Required — "Ice Barrier IS REQUIRED per section R905.1.2" — the Design Criteria table in the same document also lists "Ice Barrier Underlayment Required: Yes." About ice & water barrier
Mid-roof inspection
Required — Trigger is tile and commercial only, not standard asphalt-shingle re-roofs: "A mid-roof inspection is required for commercial flat roof assemblies and for roof tile" / "Mid-Roof Inspection required for Tile Roof Assemblies."
Impact-resistant roofing
Required — "*Impact Resistance Asphalt Shingles required per R905.2.4 (Amended): Asphalt shingles shall be Class 4 impact resistant, tested in accordance with UL2218, and installed in accordance with the manufacturer's installation instructions."
Repair permit threshold
The Town states the exemption as an area test measured in squares, not as a dollar value and not as a percentage of roof area. Its Roofing Regulations handout, published under the Town Planning and Building Department letterhead, reads: "***Repair or replacement of less than 1 square of shingles does not require a permit." Anything at or above one square of shingles is permit work, and the same handout requires the building permit to be posted on the house before work starts. The handout states no separate threshold for repairs to any other roof covering, and no dollar-value threshold appears in it.
Wind design criteria
Table R301.2(1) as printed in the Town's Roofing Regulations lists Wind Design Speed "115-140" (mph) with "Special Wind Region" and Topographic Effects "Yes" in the same cell grouping (the source table does not separate speed from the special-wind-region flag into distinct columns; quoted as printed -- treat the range as the document's own formatting, not a transcription error). Same document: "IBC Section 1609.3 (Basic Design Wind Speed) is amended to read as follows[:] The basic design wind speed, V, in mph, for the determination of site wind loads shall comply with the Colorado Front Range Gust Map - ASCE 7-10 Compatible, published by the Structural Engineers Association of Colorado (dated November 18, 2013) or the Larimer County Basic Design Wind Speed Map." The document's separate Fasteners clause is recorded under the fastening requirements.
Roof layer limit / recover
Per the Town's 2026 Roofing Regulations: "Roof recover not allowed where the existing roof has two or more applications of any type of roof covering. (R908.3.1.1)" Tear-off clause: "All roofing material shall be removed prior to new application (except one (1) layer of asphalt shingles is allowed to have an additional layer of asphalt shingles applied)" -- i.e., a maximum of two total layers (one existing plus one new) before full tear-off is required.
Deck & sheathing requirements
Per the Town's 2026 Roofing Regulations: "Plank deck underlayment is allowed if spacing does not exceed 3/8". Replace damaged or questionable roof sheathing." Underlayment layer count also varies by slope: minimum 1-layer for 4:12 and greater slopes, 2-layer for 2:12 to 4:12, modified bitumen required below 2:12.
Fastening requirements
The Town's 2026 Roofing Regulations Fasteners clause specifies "ASTM F 1667 to meet 140 Ultimate Wind Exposure C". No fastener count is stated, so the IRC R905.2.6 floor of four per strip shingle applies, with the shingle manufacturer's installation instructions governing above it. About roofing nails
Sales & use tax
Combined rate varies by county: ~8.95% in the Larimer County portion (state 2.9% + Larimer Co 1.05% + Berthoud Fire Protection District 1% + town 4%) vs ~7.90% in the Weld County portion (no county sales tax). State-collected; DOR lists a 4% use tax applying to motor vehicles and building materials.
