International Residential Code and International Building Code with Town of Firestone amendments; verify the current adopted edition with the town.
Drip edge
Required — R905.2.8.5 Drip edge. "A drip edge is required on all edges, including rakes. Minimum of 2" overlap." About drip edge
Ice & water shield
Required — R905.1.2. "Ice barriers are REQUIRED. The ice barrier shall extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building." Mid-roof checklist adds: "Ice & Water installed over the drip on the eaves and underlayment under the drip edge on rakes." About ice & water barrier
Mid-roof inspection
Required — Mid-roof inspection required for all re-roofs: "All elevations are to be dried in (Ice & Water, Drip edge, & underlayment). No more than 25% of the roof can be complete during the time of inspection." Verifies drip edge fastening (2" overlap, 12" on-center) and ice & water placement (24" inside exterior wall).
Impact-resistant roofing
Not required — Town of Firestone Ordinance No. 1029, which repealed and re-enacted Chapter 15.06 (International Residential Code) of the Firestone Municipal Code and adopts the 2018 IRC, was reviewed in full, including its complete list of local IRC amendments. The only amendment in the R905 roof-covering series is Section 15.06.160, amending IRC R905.2.8.3 (Sidewall flashing); the ordinance contains no impact-resistance, UL 2218 or Class 4 requirement. The town's re-roof requirements handout likewise addresses only wind classification, citing Table R905.2.4.1 for shingles classified to 115 mph sustained wind, which is a wind rating rather than an impact rating.
Repair permit threshold
"R105.2.11 Work exempt from permit. Repair of less than 10x10 (100 sq. ft.) No permit is required."
Wind design criteria
"IRC Table R301.2 (1).1 Climatic Design Criteria & Table R905.2.4.1 Asphalt shingles shall be classified for 115 mph sustained wind." Exposure category, topographic effects, special wind region, and windborne debris zone are not separately broken out in this guide.
Roof layer limit / recover
"R908.3.1.1 Where the existing roof has two or more applications of any roof covering, all old material must be removed. Roof recover is not allowed." Base-code rule, read at 2018 IRC Section R908.3.1.1 (Roof recover not allowed) and quoted here rather than left behind the ICC paywall: a roof recover "shall not be permitted" where "the existing roof has two or more applications of any type of roof covering" (nor where the existing covering is water soaked or deteriorated, or is slate, clay, cement or asbestos-cement tile). One existing layer may therefore be recovered; a second existing layer forces tear-off to the deck.
Deck & sheathing requirements
"R905.2.1 Sheathing requirements. Asphalt shingles shall be fastened to solidly sheathed decks."
Sales & use tax
7.0% combined (state 2.9% + Weld County 0%, no county sales tax + Frederick-Firestone Fire Protection District 0.5% + town 3.6%). State-collected; DOR lists a reduced 2.6% use tax rate (vs. the 3.6% sales rate) applying to motor vehicles and building materials, reflecting a Public Improvement Fee reduction in certain areas.
