The Town's own Roof Specifications page is titled "Town of Bow Mar 2015 Code Requirements for Residential Roofs" and directs attention to sections R904 (Materials), R905 (Roof Coverings), R906 (Roof Insulation), and R907 (Reroofing) — numbering consistent with the 2015 International Residential Code roofing chapter — plus amended provisions at R905.2.7.1 (ice barrier, 24" minimum from the eave's edge inside the heated wall line for all new tear-offs), R806.2 (roof ventilation, 1 sq ft of net free vent area per 150 sq ft of roof area), and a locally added R905.2.2 drip-edge amendment (minimum 2" overlap, extending 1.5" below sheathing). Maximum layers: 1 for shingles, 2 for flat roofing; shake re-roofs allowed at minimum #1 grade; minimum wind rating "6 nail all, 90 MPH ASTM UL D3161"; underlayment #15 up to 6/12 slope and #30 for 7/12 and above, with 2 layers required between 2/12 and 4/12; valleys minimum 18" (90 lb. or metal). The page does not otherwise cite an IBC edition for non-roofing work.

The Town's Building Permits page states: "Building Permits are required on interior and exterior work on your property. Please submit your permit application to the Building Department directly, as this is handled by Columbine Valley," at 2 Middlefield Road, Columbine Valley, CO 80123 (303-795-2063). Building/Design work is a 2-step process per the Building Procedures page: Step 1 is Design Review Board (DRB) approval for aesthetic harmony, exterior materials/colors, and setback/height/lot coverage conformance (required documents include a Roof Plan Drawing and Exterior Elevation Drawings); Step 2 is issuance of the appropriate building permit by the Town. Listed permit types include a Demolition Permit, a Non-Structural Building Permit (interior work not requiring plan review, plus some exterior items such as fences and AC units), and a Roofing Permit: "A Roofing Permit Application is required when a new roof or roof repairs are necessary. If your roofing project includes structural changes to your roof, the Building Permit Application with Plan Review is also required." Fees are based on total project valuation per a published fee table (e.g., $1,530 base for a $50,000 project) plus a 1% Transportation Utility Fee on projects of $10,000 and above. Building Permits are valid for 360 days; the Building Commissioner may assess monetary penalties if construction is not complete within that period. General project questions go to Bonnie Zapata-Diaz, Building Department Coordinator (303-795-1434, columbinevalley.org); project-specific/inspection questions go to Terry Weis, Bow Mar Building Inspector (303-522-3331), who "reviews all plans and conducts all inspections."

Terry Weis, the Bow Mar Building Inspector, "reviews all plans and conducts all inspections." Periodic inspections are made by the Building Inspector during construction to confirm compliance with DRB-approved plans and applicable building codes and Town ordinances. Bow Mar's roofing specifications separately require a mid-roof inspection at 25% of installation. One set of plans for each ongoing project is retained at the Bow Mar Building Department office (2 Middlefield Road, Columbine Valley).
