Inadequate Support Structures

Poor or inadequate support structures can significantly contribute to roof sagging. This issue usually stems from the initial construction phase, where the support beams or trusses were not adequately sized or spaced to support the roof’s weight.

Inspections can find weak spots in the roof’s support system. They allow for timely reinforcement or adjustment to stop more sagging. This is why working with a reputable and experienced contractor is crucial.

Excessive Weight
