Local building inspectors check life-safety. They don't verify the manufacturer's install spec — the exact thing that voids your warranty when the roof leaks in year five. I audit your new or recently-installed roof against IRC, IBC, NMCID, and the manufacturer's own printed spec, and cite the code section for every finding.
IRC 2018 (residential) or IBC 2018 (commercial) audit
NMCID amendment cross-check
Manufacturer install-spec verification (nailing, laps, flashings)
Ventilation compliance (1:150 or 1:300 net free area)
Ice-and-water shield placement for northern NM elevations
Cited-code report you can attach to a punch list or retention hold
Full walk with code-compliance focus on a new or recently-installed roof. Every finding cross-referenced to IRC/IBC/NMCID section number. Manufacturer install-spec verification per shingle/tile/membrane brand. Ventilation math (intake vs exhaust net free area). Flashing details vs manufacturer's own printed spec drawings. Ice-and-water shield placement for northern NM elevation zones. Written report with per-finding code citation and photo evidence.
NM owners with a newly-installed roof considering a retention hold. Owners whose manufacturer warranty was denied for install reasons. Commercial building owners under IBC jurisdiction. Insurance claims where install-defect is disputed. Buyers under contract on a home with a permit-pulled re-roof in the last 24 months.
Residential Code Audit — $549 Commercial Code Audit — $849 Manufacturer Spec Deep-Dive — $1,200 Retention-Hold / Litigation Grade — $1,500+ Most residential code audits are $549–$1,200. A cited-code report typically holds enough retention to pay for itself several times over.
Residential roofs follow the 2018 IRC as amended by NMCID. Commercial follows the 2018 IBC. Both incorporate manufacturer install specs by reference — meaning if the roofer skipped a fastener count or a starter course, they violated code even if the local inspector signed off.
Local inspectors check life-safety items and general workmanship. They rarely verify manufacturer install specs (nailing pattern, underlayment overlap, drip-edge integration). Those are the exact items that void warranties and cause leaks 3–7 years in.
Yes. A cited code violation report is defensible leverage to hold retention until fixed. I stick to what I can prove with the code text — no opinion, no leverage games.
Manufacturer + workmanship defect audit.
Yearly punch-list + service-life estimate.
Pre-listing & buyer due-diligence reports.
Reserve study + per-unit documentation.
I've watched too many neighbors sign contracts they didn't understand for roofs they didn't need. That stops with a written report they own.
