Sagging Roof: Causes and Solutions

A sagging roof can be a major source of concern. While mild sagging does not always indicate imminent collapse, you should address the issue as soon as possible. Continue reading to learn why roofs sag and the best solutions for fixing the problem based on the cause. 

Why Does Roof Sagging Occur?

The following are some of the main causes behind roof sagging:

1. Excessive Weight on the Roof
Too much weight on your roof’s structure might cause it to sag. It can happen when there’s a lot of ice and snow on top of your home. This issue is also typical in roofing systems with excessive shingle layers. Poor design or construction, aging and problems with your home’s foundation can all cause structural issues with the roof.

2. Inadequate Support
The main roofing structure is supported by a series of joists and rafters. These are where you view your ceiling as well as the base of the roof. From the ridge to the margins, the rafters run diagonally. If these are insufficient, or if they were built incorrectly, the problem can cause the roof to sag.

3. Insufficient Attic Ventilation
Moisture and heat can build up in your attic due to poor ventilation. Water will be able to seep into the roof’s surface more easily if this occurs. Excessive moisture and heat can also cause shingles to deteriorate prematurely.

4. Old Age
When a roof reaches the end of its useful life, it begins to deteriorate. Roofs can easily survive more than a decade with proper roofing maintenance. However, if you notice your roof is beginning to sag, you should contact a licensed roofing specialist for residential roof replacement as soon as possible.

Dealing With a Sagging Roof

Roof repair is still doable in most cases of sagging, but it must be done by an experienced contractor. They may place angled bracing to add support to the rafters depending on the situation. They can also use chains to reinforce the barriers. Before they can install any more bracing, they will most likely utilize jack posts to help lift the drooping.
