Pigeons, rock squirrels, pack rats, and bats do real damage to NM roofs — acidic droppings on shingles and stucco, blocked ridge vents, nesting under swamp coolers, and entry paths that turn into water intrusion. I document the species, the material damage, and the exclusion sequence so pest control and roof repair actually coordinate.
Species identification via droppings, entry holes, and nest signatures
Granule loss and stucco erosion mapping from acidic droppings
Swamp cooler platform and vent nesting audit
Ridge vent, gable vent, and soffit entry-point inventory
Exclusion-vs-repair sequencing so trades don't undo each other
Written scope covering pest control, exclusion, and roof repair phases
Full roof walk with pest-damage focus. Species identification via droppings, entry holes, and nest signatures. Granule loss and stucco parapet erosion mapping from acidic droppings. Swamp cooler platform, curb, and duct nest inventory. Ridge vent, gable vent, and soffit entry-point mapping. Attic entry-trace where signs of interior activity are visible. Written scope sequencing pest control → exclusion → roof repair.
NM homeowners with visible pigeon activity or droppings on the roof. Swamp cooler owners hearing scratching or nesting in the platform. Homeowners with rodent activity in the attic wanting to trace the entry. Property managers with recurring pest complaints on commercial roofs. Owners after pest control who want the roof-side repair scoped correctly.
Verbal Walk — $149 Standard Bird & Pest Damage Report — $349 Detailed w/ Attic Entry Trace — $549 Commercial / Multi-Building Pest Audit — $900+ Most residential bird and pest reports are $349–$549. Sequencing pest, exclusion, and roof correctly typically saves one full treatment cycle ($400–$800) and one aborted roof repair.
Real damage. Pigeon droppings are acidic and eat asphalt shingle granules and stucco parapet coatings on 2–5 year cycles. Nesting under swamp cooler platforms, in ridge vents, and behind gable vents blocks ventilation and creates entry paths for water. I document material damage vs cosmetic staining so you scope the right repair.
Usually. Pigeon vs sparrow vs rock squirrel vs pack rat vs bat each leave distinctive droppings, entry-hole sizes, and nest signatures. I document the species evidence in the report so your pest control company doesn't waste a treatment cycle guessing.
Pest control first, then exclusion, then roof repair — always in that order. If a roofer seals up an active nest, you get dead animals in the attic and a much bigger problem. I coordinate the sequence and my report tells both trades what to do and when.

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.
