San Jose rooftops carry more residential solar than almost anywhere in the country, and the city's pigeons figured that out years ago. The gap between a solar array and the roof surface is warm, shaded, and safe from hawks — ideal nesting real estate. One pair moves in under a panel in Willow Glen, Berryessa, Almaden, or Evergreen, and within a season you have a colony, a carpet of droppings baking onto the tiles, and cooing over your bedroom at dawn. The droppings are the real cost: acidic enough to etch wiring insulation, panel frames, and roof material, and every month the colony stays, the cleanup gets bigger.
We close the perimeter of the array with galvanized, UV-stable wire mesh secured by clips that grip the panel frame. No holes in the panels, no holes in the racking, no holes in your roof — which means no new leak points and no voided warranty. The mesh sits tight to the roofline, so from the street most neighbors never notice it is there.
Installing mesh over an active nest just seals the problem in. We flush the birds out, clear every nest and all debris from under the array, scrape the accumulated droppings, and sanitize the roof surface before anything gets closed up. Dried pigeon droppings are a genuine health hazard when disturbed — this step is not optional and we do not skip it.
Every job ends with a full deionized-water wash of the array — the same process as our San Jose solar panel cleaning service. Droppings on the glass cost you real production. The array should leave the job producing more than it has in months.
No poisons, no traps, no killing. The birds lose access and relocate — that is the whole method. A poisoned colony gets replaced by the next one within weeks; a sealed array stays sealed.

Measure the exposed perimeter of the array, locate every access gap, and gauge how established the colony is. The quote is based on your actual roof and panel layout, not a flat rate.
Flush the birds out, then clear nests, feathers, and debris from under the panels. Nothing living and nothing flammable gets sealed under the mesh.
Scrape the accumulated droppings from the roof surface, then sanitize under and around the array. The acid and the pathogens come off the roof before anything is closed up.
UV-stable wire mesh clipped to the panel frames around the full perimeter. No drilling into panels, racking, or roof — no leak points, no warranty issues.
Deionized-water wash of the entire array, then a perimeter walk to confirm zero gaps remain. Before and after photos documented for your records.

These photos are from a bird proofing job we completed in Palo Alto — the same mesh, the same clips, and the same cleanup process we run on San Jose solar arrays.

We install a wire mesh barrier around the full perimeter of the array, secured with clips that grip the panel frame. Nothing is drilled — not the panels, not the racking, not the roof. The mesh follows the roofline and is barely visible from the street.
No. The clips grip the aluminum frame edge without penetrating it, so your panel warranty and your roof warranty are unaffected. Drilled or glued barriers are the ones that cause warranty problems — we do not install them.
They leave, unharmed. We flush the birds out and remove every nest before the mesh goes on, so nothing gets sealed underneath. This is humane exclusion, not extermination — no poisons, no traps, no killing.
Both. Pigeon droppings are acidic enough to etch wiring insulation, panel frames, and roof material. We scrape the buildup, sanitize the roof surface under and around the array, and wash the panels before we leave.
Yes. Once the mesh is on, we wash the full array with deionized water and soft brushes — the same process as our solar panel cleaning service. Most arrays see a noticeable production bump once the droppings and grime are off the glass.
Most residential arrays are done in a single visit — assessment, nest removal, sanitizing, mesh installation, and panel wash. Large arrays or long-established colonies can run into a second day.
The mesh is galvanized steel with a UV-stable coating and typically lasts 10 years or more. The clips are stainless, so no rust streaks down your tiles or shingles.
