How to Identify This Problem
Look for these warning signs:
- Visible dip or curve in the roofline when viewed from the street
- Wavy or uneven appearance to roof surface
- Interior ceiling appears to bow or droop
- Doors or windows becoming difficult to open/close
- Cracks appearing in interior walls
- Creaking sounds from the attic or ceiling
- Soft spots when walking on roof (if accessible)
Common Causes
Water Damage to Decking
Long-term leaks rot the plywood decking, causing it to weaken and sag between rafters.
Inadequate Structural Support
Rafters or trusses spaced too far apart, or undersized for the roof span, cannot support the weight.
Too Many Roofing Layers
Multiple roof layers add excessive weight that the structure was not designed to support.
Termite or Pest Damage
Termites, carpenter ants, or other pests can hollow out rafters and support beams.
Age and Deterioration
Over decades, even properly built structures can weaken as materials fatigue.
Improper Original Construction
Building code violations or shortcuts during construction can lead to premature failure.

Frequently Asked Questions
Can a sagging roof be repaired or does it need replacement?
It depends on the cause and extent of damage. Minor sagging from localized water damage may be repairable. Widespread structural issues typically require more extensive work. A professional structural assessment is essential to determine the best course of action.
How quickly does a sagging roof need to be fixed?
A sagging roof should be assessed by a professional immediately. While complete collapse is not always imminent, the risk increases over time, especially with additional weight from rain or wind loads. Do not delay - this is a safety issue.
Will insurance cover sagging roof repairs?
Coverage depends on the cause. Sagging from sudden events like storms or tree impacts is typically covered. Sagging from long-term neglect, age, or gradual deterioration is usually not covered. Document the damage and review your policy or consult with your agent.
