## Code reference (built here)

`IRC_Chapter9_Asphalt_Shingle_Roof_Belton.pdf` (15 pp; source `.html` alongside) — legible transcription of the asphalt-shingle sections of IRC Chapter 9 from screenshots 1–26.png (R901, R902.1, R903.1–R903.2.2, R904, R905.1–R905.1.2 with Tables R905.1.1(1)–(3), R905.2 through R905.2.8.5 with Tables R905.2.4.1 and R905.2.8.2, R908.1–R908.3.1.1, R908.5–R908.6) plus an appendix with Belton's Table R301.2(1) amendments and the City's roof inspection item. Non-code notes are in boxes labelled "Belton". Re-print from the HTML with Edge headless if edited.

## Gaps / uncertainties

- **Underlayment**: Tyvek Protec 120 (used). Duration instructions require a synthetic meeting ASTM D8257; DuPont's product info sheet lists ASTM D8257 compliance, so it satisfies OC's requirement. Note Tyvek's own rule: where the shingle maker's lap/fastening requirements differ, follow the more restrictive. Must be covered within 3 months.
- **ARMA manual editions**: 1984, 1988, 1993, 1997, 2006, 2014, 2022. The 2014 edition is free (saved here); 2022 is paid. A 1984 copy predates synthetic underlayment, ASTM D1970 ice barrier, laminated-shingle nailing guidance, and modern IRC flashing rules; do not rely on it.
- **Step flashing (Gibraltar 4X4X8GALVBL-100)**: Gibraltar publishes no dedicated install sheet. Governing text = IRC R905.2.8.3 (sidewall flashing) + Duration install instructions + ARMA manual ch. 10.
- **Drip edge / gutter apron / valley manufacturer**: gutter apron GA-WH and step flashing 4X4X8GALVBL are confirmed Gibraltar model numbers. Drip edge ADE12-WH matches Gibraltar's ADE12 family (strong match, not confirmed on packaging). Valley SKU 1571357 is a Menards-internal model; maker unconfirmed (Gibraltar or Menards' Midwest Manufacturing). Check the label on the piece.
- **Code — Belton, MO (RESOLVED 2026-09-05)**: Belton adopts the **2018 IRC** with local amendments (UDC Sec. 10-5; 2018 I-codes effective 2023-01-01 per belton.org). Local Table R301.2 values, from the City's own letter `Belton_MO_Ice_and_Water_Shield_Requirement_Letter.pdf`: **Ice barrier required = YES**, wind design speed 115 mph, ground snow 20 psf, weathering severe, winter design temp 6 F. City inspection checklist (`Belton_MO_Inspection_Guidebook.pdf`): roof inspection = "Sheathing, ice and water shield and underlayment, drip edge, valleys, and venting installed to adopted codes." Mid-phase roof inspection + final.
- **Screenshots 1–26.png** in this folder are IRC Chapter 9 as shown on UpCodes, **2021** edition (R905.17 BIPV panels and R902.3/R902.4 solar sections are 2021 additions). **Verified 2026-09-05 against 2018 text** (`IRC_2018_R905_Roof_Coverings_text_PacificMO_handout.pdf` + Seattle's 2018 reprint): R905.1.1 incl. both exceptions, R905.1.2 ice barrier, R905.2.5 fasteners, R905.2.6 attachment, R905.2.8.2 valleys, R905.2.8.3 sidewall, R905.2.8.5 drip edge are **word-for-word identical** in 2018 and 2021. The screenshots can be used as-is for the asphalt-shingle rules. Free 2018 text: https://codes.iccsafe.org/content/IRC2018/chapter-9-roof-assemblies (browser only).
