Roofing questions — Ignacio, CO

Do you need a permit to replace a roof in Ignacio, CO?

Required. No dollar-value or minor-repair threshold specific to roofing work exists. Municipal Code Section 5-3-1 requires a building permit for alteration of any building or structure regardless of job value, and the unamended 2018 IRC Section R105.2 exemption list, which the Town did not amend, contains no roof-covering item and no cost-based exemption for roofing work. Section R105.2.2's "ordinary repairs" exemption reads: "Application or notice to the building official is not required for ordinary repairs to structures... Such repairs shall not include the cutting away of any wall, partition or portion thereof, the removal or cutting of any structural beam or load-bearing support..." and does not name roof covering or roof replacement.

Is ice & water shield required in Ignacio, CO?

Required — The Town's own Table 301.2(1), Climatic and Geographic Design Criteria, added by Ordinance 357 Section 5-6(4), sets "Ice Shield Underlayment Required: Yes" for Ignacio. Under the unamended 2018 IRC Section R905.1.2 that this table triggers, "In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2(1), an ice barrier shall be installed," consisting of not fewer than two layers of underlayment cemented together, or a self-adhering polymer- modified bitumen sheet, extending from the lowest roof edges to a point not less than 24 inches inside the exterior wall line, for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes..

Is drip edge required?

Required — Unamended 2018 IRC Section R905.2.8.5, Drip edge, provides: "A drip edge shall be provided at eaves and rake edges of shingle roofs. Adjacent segments of drip edge shall be overlapped not less than 2 inches (51 mm). Drip edges shall extend not less than 1/4 inch (6.4 mm) below the roof sheathing and extend up back onto the roof deck not less than 2 inches (51 mm). Drip edges shall be mechanically fastened to the roof deck at not more than 12 inches (305 mm) o.c. with fasteners as specified in Section R905.2.5. Underlayment shall be installed over the drip edge along eaves and under the drip edge along rake edges.".

Is a mid-roof inspection required?

Not required — No mid-roof, dry-in or underlayment inspection is required in Ignacio, and the Town says in terms where the answer lives. Municipal Code Chapter V, section 5-3-5 (Inspections) provides: "Inspections shall be completed for all inspection and coordinated with the Building Department. THE CODES DEFINE SPECIFIC INSPECTIONS and the Building Department can modify inspections when deemed necessary." Section 5-3-2(2) points the same way -- "Inspections required under the provisions of the building code shall be made by the Building Inspector or duly appointed inspector" -- so the Town creates no stage of its own and defers to the adopted code. Chapter V was then read in full, 44,000 characters, and measured: ZERO occurrences of "R109", ZERO of "R905", ZERO of "R908" and ZERO of "shingle". Ignacio amends neither the inspection section nor the roofing chapter. ⚠️ Of the six places the anchored word "roof" does appear, none is a roofing rule: five are column headings in the Table R301.2 climatic and geographic design criteria, and the sixth is plumbing -- "903.1 Roof extension. Open vent pipes that extend through a roof shall be terminated not less than 6 inches above the roof", which is a vent-termination requirement in the adopted plumbing code and has nothing to do with roof covering. So the governing scheme is the base code's. Ignacio adopted the 2018 International Residential Code at Municipal Code Section 5-1-1 by Ordinance 357 (June 12, 2023), and 2018 IRC Section R109 was read directly: foundation, plumbing/mechanical/gas/electrical rough, floodplain, frame and masonry, other, fire-resistance-rated construction, and final. There is no roof-covering stage, and the section's single use of the word "roof" is R109.1.4, which takes the framing inspection "after the roof, masonry, framing, firestopping, draftstopping and bracing are in place." ⚠️ ONE LOCAL QUALIFICATION A ROOFER SHOULD NOT IGNORE: section 5-3-5 expressly lets the Building Department "modify inspections when deemed necessary." That is a stated power to add an inspection to a particular job, so confirm the inspection schedule for a specific permit with the Building Department rather than assuming the base list is exhaustive..

Do roofing contractors need a license or registration in Ignacio, CO?

Not required. No Town-level general contractor license or roofing-specific registration requirement was found in Municipal Code Chapter V (Building and Excavation) or on the Planning Department page. The Town's Forms page separately lists a "Business Service License Application (for a business located outside of Town limits)" alongside a "Business License Application (for a business within Town limits)," but these are general business licenses, not a construction-contractor license tied to building permits..

What building code does Ignacio, CO use?

Municipal Code Section 5-1-1 (Ordinance 357, adopted June 12, 2023) adopts the 2018 editions of the International Building Code, International Residential Code, International Mechanical Code, International Plumbing Code, International Fuel Gas Code, International Energy Conservation Code, International Existing Buildings Code, and International Property Maintenance Code, each "together with Amendments and Deletions" set out in Sections 5-5 through 5-12. Local IRC Table 301.2(1) sets a 40 psf ground/roof snow load, 90 mph wind speed (Wind Design, Topographic Effect "Yes"), Seismic Design Category "C," and "Ice Shield Underlayment Required: Yes." All references to the ICC Electrical Code are amended to the latest National Electrical Code edition adopted by the State of Colorado.
