Sagging Roof
A sagging roofline is a serious structural warning sign. This indicates potential collapse risk and requires immediate professional evaluation. Do not ignore this problem.
Safety Warning: Do not walk on or store items in areas beneath a sagging roof. Evacuate the area and call a professional immediately if you notice rapid progression.
What Causes a Roof to Sag?
Water Damage
Long-term moisture weakens rafters and decking, causing them to bow.
Structural Failure
Broken or undersized rafters, trusses, or supports.
Excessive Weight
Too many shingle layers, heavy equipment, or snow/ice accumulation.
Foundation Issues
Settling foundation can shift wall supports, affecting roof structure.
Age Deterioration
Wood naturally weakens over decades, especially without proper ventilation.
Poor Original Design
Inadequate support for roof span or load requirements.

Frequently Asked Questions
Is a sagging roof dangerous?
Yes. A sagging roof indicates structural compromise that could lead to partial or complete collapse. This is especially dangerous during storms or heavy rain. We recommend immediate professional inspection and avoiding the area beneath the sag.
Can a sagging roof be repaired or does it need replacement?
It depends on the cause and extent. Minor sagging from localized damage may be repairable by sistering rafters or replacing decking. Severe structural failure often requires significant reconstruction. We provide honest assessments of repair vs. replacement options.
Will insurance cover sagging roof repair?
If the sag resulted from a covered event (storm damage, fallen tree), insurance typically covers repairs. Sagging from neglected maintenance or age is usually not covered. We document the cause carefully to support legitimate claims.
