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.
