Roof rat exclusion means sealing every gap larger than a quarter inch—think soffits, rooflines, and vents—with wire mesh or metal flashing. It’s stubborn work because these rats climb trees and power lines to sneak in. I’ve seen crews trimming branches back six feet from eaves and double-checking chimney caps. A thorough job stops the scratching and droppings, but it requires patience and a sharp eye since rats squeeze through tiny holes.
