Ag roofs get ignored until something falls on livestock. Exposed-fastener panel audits, purlin corrosion mapping, translucent-panel scoring, and honest snow-load review for the northern NM operations that actually see snow. I write scopes USDA-financed operations, county extension offices, and equine facility owners can use.
Exposed-fastener screw and gasket audit (statistical sampling + full mapping in failure clusters)
Purlin, girt, and connection corrosion scoring — interior and exterior
Translucent skylight panel replacement mapping (fiberglass and polycarbonate)
Snow-load review for northern NM operations and mountain elevations
Ridge, gable, and eave trim audit — bird and wind entry
Written scope: repair, re-screw, panel replacement, or overlay with material lifecycle math
Full agricultural roof walk with statistical fastener sampling every 10th purlin line. 100% mapping in fastener-failure clusters (backed-out screws, spinning gaskets, slot cracking). Interior purlin and girt corrosion scoring — hay respiration, livestock ammonia, and condensation zones flagged. Translucent skylight panel condition mapping in compatible profile for spot-replacement scoping. Snow-load review against NM CBC and county requirements (Taos, Los Alamos, Angel Fire elevations). Ridge cap, gable trim, eave closure, and bird-block audit. Written scope: re-screw, panel replacement, purlin sistering, or full metal-over-metal overlay with 20/30/40-year lifecycle math.
NM ranchers, farmers, and equine facility owners with metal barns, stables, arenas, and hay storage. USDA-financed operations needing defensible inspection documentation for loan servicing. County extension offices and 4-H facilities managing shared ag structures. Buyers under contract on rural properties with outbuildings. Owners in northern NM (Taos, Chama, Angel Fire) needing snow-load verification.
Verbal Walk — $149 Standard Barn Report — $399 Detailed w/ Fastener Cluster Mapping + Purlin Audit — $649 Multi-Structure Ranch Package (3+ buildings) — $299 per additional structure Snow-Load Review Add-On — $199 Most barn inspections are $399–$649. Catching purlin corrosion before a snow-load event saves the $18,000–$60,000 rebuild — and the livestock.
I sample statistically — every 10th purlin line plus every accessible penetration and eave. Fastener failure clusters (backed-out screws, spinning gaskets, hairline slot cracks) get 100% mapped in the affected zone. You get a defensible sample, not a guess.
Big deal on ag roofs. Hay respiration puts real moisture into the underdeck; I check purlin corrosion, condensation staining, and any interior liner panels for delam. Ventilation adequacy is scored against stored-hay volume, not just building volume.
Yes. Fiberglass translucent panels degrade fast in NM UV — 8–12 years vs the 20+ years of the surrounding steel. I map yellowed, cracked, and spalled panels for replacement in a compatible profile so you're not tearing off good steel to swap a $180 light panel.
SMACNA sizing + downspout audit.
Bid + scope compared line-by-line.
Hail/wind + NOAA event correlation.
Map wet insulation before you recoat.
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.
