Roofing systems are designed to last for a long time, protecting homes and commercial buildings and their occupants from the elements at all times. As with anything, however, time and the elements contribute to roof deterioration. One of the most serious problems that can befall a roof is sagging. Unfortunately, it is also one of the most common.
When a roof sags, there is something wrong with its structural integrity. But what exactly causes a roof to lose its form this way? Here are some possible explanations:
The Roof Is Old
If you notice that your roof is sagging, think about its age. With an old roof, the most common culprit behind sagging is deterioration over the years. It’s important to start thinking about a roof replacement if old age is already causing it to sag. It’s unsafe to ignore this problem because the worst-case scenario is the roof collapsing and hurting someone. Think about the dangers of a roof caving in due to the strength of a storm.
The Roofing Materials Are Too Heavy
A professional roofing contractor is very capable of determining how much weight the roof structure (trusses, beams, walls, etc.) can carry before it becomes dangerously unstable. Even if your roof is new, if it’s too heavy, it can show signs of sagging. The common culprit is the addition of a new layer or several layers of roofs over older layers. In some counties and states, the practice of re-roofing, or installing a layer of new shingles over the old layers, is not allowed. One of the reasons for this is the additional burden that the new layer of materials gives to the structure.
The Roof Is Poorly Designed
Either the roof was not designed well, to begin with, or some modifications have been made to a structurally sound roof that has since compromised its integrity. This kind of sagging is often difficult to repair, as it might necessitate a complete roof redesign.
The Roof Is Neglected
Roofs can last long if they receive regular upkeep. Without proper maintenance, damage can develop without your knowledge, and you might only notice it when the roof is already leaking or sagging.
