Pigeons (and other flying demons) just love to nest—and nest they will on your building ledges, roofs, and eaves. And once they’ve set up shop, bird nests can block drainage pipes, rain gutters, vents, or chimneys, creating water leaks and potential fire hazards.
Believe it or not, birds nesting in attics have also been known to cause ceilings to collapse. Over time, poop, nesting materials, and standing water can build up, ultimately becoming too heavy for ceilings and roofs to support the weight. Well, let’s hope you at least took out a good insurance policy.
