Water can seep into even small cracks in the roof tiles and run down the inside of your roof, eventually damaging your house’s ceiling. 

Ceiling leaks can further damage insulation, drywall, electrical wiring, walls, and the home’s structural integrity.

Damaged flashing

Flashing is a waterproof material that prevents water from seeping in through openings in the roof, such as chimneys, vents, and skylights.
