Why Tracy arrays attract pigeons specifically
The gap between a module and the roof deck is a warm, covered, predator-free ledge, which is exactly what a nesting pigeon is looking for.
Tracy has the combination that produces the worst infestations: dense rooftop solar adoption across newer villages and open feeding ground on the edges of town. Birds feed in the fields and roost under the panels.
Nesting is worse on split-plane roofs where one section faces away from the street, because the colony builds undisturbed for a full season before anyone notices from the driveway.
Clipped mesh on Tracy roofs, no fasteners in the array
Stainless mesh is held by clips that grip the module frame, so nothing penetrates a panel, the racking or the tile.
Screwed-in barriers are the fast way to void a solar warranty and create a roof leak path. The clip system loads onto the aluminum frame lip and holds the mesh tight against the roof plane around the full perimeter.
Mesh is stainless, not plastic or galvanized wire. Plastic degrades under valley UV inside two summers and galvanized rusts where it contacts the frame.
Cleanup is not optional in Tracy
Nesting material and accumulated droppings come out before the mesh goes on, and the roof surface is sanitized.
Sealing a colony in is worse than doing nothing. Every nest, egg, feather mat and droppings layer is removed first, bagged and hauled off, then the area is treated so the pheromone trail stops attracting returns.
Cleanup starts at $200 and is quoted from the actual volume found, because a one-season nest and a four-year colony are entirely different jobs. You get the number in writing after the array is inspected.
Cleaning the Tracy array while access is staged
Panel washing drops to $10 per module on a proofing visit because the ladders, water and roof access are already set.
Droppings on glass shade cells and bake on hard in Tracy summer. Washing at the same appointment is half the $20 standalone rate, and it gives you a clean baseline to measure production against.
The visit closes with photographs of the mesh line all the way around, the cleaned roof plane, and the washed array.
Tracy arrays in Tracy Hills and Edgewood are the ones we proof most often, and a Tracy address in 95376 or 95377 sits on a routed day rather than a special trip.
