1. Structural Damage: Prolonged exposure to water can weaken roofing materials and compromise the underlying structure, leading to issues such as rotting wood, weakened beams, and potential collapse.

2. Mold and Mildew Growth: Moisture intrusion creates an ideal environment for mold and mildew, which can spread rapidly. This not only damages building materials but also poses serious health risks, particularly for individuals with respiratory issues or allergies.

3. Insulation Damage: A leaking roof can saturate insulation, reducing its effectiveness and leading to increased energy costs. Damaged insulation may also necessitate costly replacements.

4. Pest Infestation: Water damage can attract pests such as insects and rodents, which may seek shelter in compromised areas of the roof or walls, leading to further structural damage and health concerns.

5. Decreased Property Value: Persistent leaks and their consequences can diminish the overall value of a property, making it less attractive to potential buyers and resulting in costly repairs.
