Not required
Permit process note

Commercial roofing and structural work still require a permit, and incorporated cities within the county permit separately.
Adopted code
International Residential Code and International Building Code with Weld County amendments; verify the current adopted edition with the county.
Drip edge
Required — Not separately amended by Weld County. The county adopts the 2024 IRC by reference (Weld County Code Sec. 29-2-30) and its amendment list does not delete or modify R905.2.8.5, so the base IRC drip-edge requirement stands as adopted code. Note: re-roofing of one- and two-family dwellings and non-commercial detached accessory structures using finish materials only (shingles, roof panels, metal panels) is exempt from permit (Sec. 29-2-20.G item 16), so this standard is not permit-enforced or inspected for most residential re-roofs.
About drip edgeIce & water shield
Not required — Weld County's amended IRC Table R301.2(1) (Climatic and Geographic Design Criteria, Sec. 29-2-30.B, amending Table 301.2) lists "ICE SHIELD UNDER-LAYMENT = NO" as the countywide determination.
About ice & water barrierMid-roof inspection
Not required — Re-roofing of one- and two-family dwellings and non-commercial detached accessory structures using finish materials only is exempt from permit under Sec. 29-2-20.G item 16 ("Amend Section 105.2 Work exempt from permit"), and permit-exempt work is not subject to inspection, including any mid-roof inspection.
Impact-resistant roofing
Not required — No Weld County amendment mandates Class 4 / UL 2218 impact-resistant shingles. The full text of the county's IRC (Sec. 29-2-30) and IBC (Sec. 29-2-20) amendment lists was reviewed and contains no such addition (no R905.2.4.2 or 1504.8.1-style amendment, unlike neighboring Boulder and Larimer counties).
Wind design criteria
Weld County's amended IRC Table R301.2(1) (Sec. 29-2-30.B, "Amend Table 301.2") lists "WIND SPEED | 115 Nominal 3 sec gust" as the countywide determination. The table as printed does not break out separate topographic-effects, special-wind-region, or windborne-debris-zone columns; only ground snow load (30 psf), wind speed, seismic design category (B), and the other standard R301.2(1) climatic cells are given.
