Does your roof have a curvy or wavy appearance as opposed to a straight one? It’s likely because of a sagging problem. A sagging roof is often caused by insufficient structural support. This is also a common problem in older houses due to the way roofs used to be built. Either way, a sagging roof should be remedied as soon as possible. Otherwise, it can compromise the integrity of your home and lead to costly repairs.
As one of the top roof repair services providers in Iowa, Genesis Roofing discusses what you need to know about a sagging roof.
What Are the Causes of a Sagging Roof?
The angles of your roof should be as straight as possible. Over time, however, it can sag or show other signs of distress. Here are a few reasons why this happens:
- Moisture damage. If your gutters or downspouts are unable to deflect water away from your roof, it can seep through and wreak havoc on your roofing system. The trapped moisture allows mold and mildew to thrive, weakening framing members and causing rot. Be sure to schedule annual roof inspections with your local roofing contractor to ensure your roof is in great shape.
- Inadequate roof joists and rafters. It’s helpful to think of your roof as a triangle. The base forms the ceiling or roof joists, while the rafters slant toward the ridgeline. The weight of your roof relies on the roof joists, rafters, and walls of your home. If they are poorly constructed, this can lead to a sagging roof later on. A roof that isn’t built properly is sure to fail and become structurally unstable.
- Old age. While regular roof maintenance can help extend the lifespan of your roof, you will still need to replace your roof sooner or later. Once your roof reaches the end of its useful service life, it may start to sag. In this case, be sure to call a roofing expert right away for roof restoration or replacement.
How Can You Fix a Sagging Roof?
Depending on the extent of the damage, there are plenty of remedies for a sagging roof. For traditional rafter-style roofs, the framing can be internally bolstered. If the roofing material requires replacement, it’s best to tear off the old sheathing and install bigger rafters while the roof frame is exposed. However, in the event of widespread and severe sagging, you may need a roof replacement.
