When you need this permit
- Building permit required for re-roofing under Greeley's adopted 2021 IRC / 2021 IBC (roofing is not on the Sec. 22-33 permit-exempt work list)
- Roofs with slopes below 2:12 require a low-slope roof membrane (not standard asphalt shingles); slopes 2:12 to 4:12 require 19-inch lapped underlayment; slopes 4:12 and greater require one layer of underlayment, per the Colorado Chapter ICC Re-Roofing guide referencing 2021 IRC Chapter 9
- Ice barrier (self-adhering underlayment) required per 2021 IRC R905.1.2 in areas with a history of ice damming; drip edge required at eaves/gables covering a minimum 2 inches onto the roof deck
- Attic/roof-cavity ventilation required per IRC R806.2 (1/150 net free vent area, reducible to 1/300 with proper intake/exhaust and vapor retarder in cold climate zones)
- Shingle fastening: 4 nails per strip standard, 6 nails per strip in high-wind areas (designated wind speed over 90 mph) — relevant given Greeley's 115 mph adopted design wind speed
- Installations above 7,500 feet elevation require additional ice/water protection measures per manufacturer instructions (not directly applicable at Greeley's ~4,650 ft elevation, but the Colorado Chapter guide flags it for reference)

Tips
- No dedicated published re-roof-specific fee table exists; re-roof permits are governed by the same general valuation-based Building Permit Fee Schedule that applies to all building permits (Secs. 22-33, 22-34), with the $75 minor-review fee applicable to smaller residential reroof scopes (verify exact valuation tier with Building Inspection at 970-350-9830).
- The City's Building Permits and Inspections page does not publish a re-roofing-specific review timeline; re-roofing is an alteration to an existing structure (not new construction), so it is governed by the same 10-working-day 'Additions/remodels plan review' track published on that page.
- Below 2:12 slope, standard asphalt shingles are not allowed — a low-slope membrane product is required.
- Greeley's adopted 115 mph basic wind speed exceeds the 90 mph threshold that triggers the Colorado Chapter ICC guide's 6-nail-per-strip high-wind shingle fastening pattern — confirm fastening schedule with your roofing manufacturer and the Building Inspection Division.
