So this netting is there to stop the pigeons from landing, and obviously it isn’t working. Birds don’t like landing on things they cannot see. With the netting in place the birds should refrain from landing and the load of the roof with feces should be minimized. Over years the buildup of feces can add considerable weight to the structure and possibly cause the collapse.
What can be done?
- Readjust the netting, create higher peaks.
- Possibly add deterrents like mechanical owls or flashing devices.
- Birds are adaptable so you must think and be proactive.
If this is a house with birds or pigeons, you must stop them from nesting. Use hardware cloth NOT chicken wire. Think like the birds. Call a Pest Management Professional such as ProBest Pest Management 480-831-9328
