Roof access, tile surfaces and solar equipment add fall and electrical risks. Heavy accumulations of dried droppings also deserve appropriate cleanup precautions rather than casual sweeping that creates dust.
What problem are you actually solving?
If pigeons repeatedly roost or nest in the same protected gap, ask about exclusion—not only removal or cleanup.
Tell the provider before booking. Ask how guards attach, whether panel/roof warranties are considered, and whether nests are removed before the perimeter is closed.
Clarify whether cleanup/sanitation is included with exclusion or priced separately. Do not assume installing mesh includes removing the existing mess.
Occasional perching is different from an established nesting problem. An inspection can help avoid paying for a larger treatment than the situation requires.
Ask about the permanent part of the fix.
- What access point or roost will be blocked?
- For solar arrays, how is the mesh/guard attached without unnecessary roof or panel damage?
- Are nests, feathers and droppings removed before exclusion?
- What warranty applies to the installed exclusion work, and what does it actually cover?
