The space under a rooftop array is shaded, sheltered and warm, which makes it a perfect nesting spot. Homes near a pool or any water source see it most. Once one pair moves in, more follow.
Pigeon droppings are acidic and eat away at tile and shingle over time. Nests trap leaves and desert debris against the roof, block drainage and sit right next to the wiring that runs your system. Most arrays are built to last 20 to 25 years, so closing the gap early protects the whole roof.
Roof damage
Acidic droppings break down tile and shingle, and blocked drainage holds water against the roof.
Wiring risk
Nesting birds and other wildlife can chew or pull at the wiring under your panels.
Noise and mess
Cooing at dawn, droppings on the patio and feathers in the yard all stop once the gap is sealed.
