The Top 5 Causes Of Roof Collapse

With the record rains, blizzards, and even tornados hitting Los Angeles this year our roofs have taken quite the beating. In fact, there have been many cases of complete roof failure after all the weather we’ve been getting in Los Angeles. 30 years in the roofing industry we can say that, unfortunately, roof collapse is relatively common and can happen for various reasons.  Here are The Top 5 Causes Of Roof Collapse. Let’s dive in!


1) Structural failure:

A roof’s structural integrity can be compromised by a variety of factors, such as weak materials, poor design, inadequate construction, or damage from weather events like high winds or heavy snow. This can cause the roof to collapse under its own weight or from the added weight of snow or debris.

2) Water damage:

Water damage can weaken the structure of a roof, especially if it is not properly maintained. Water can seep into the roof and cause rot, which can weaken the roof’s structure over time.

3) Age:

As the roof ages, it can become weaker and more susceptible to collapse. This is especially true for roofs that have not been properly maintained or have been subjected to extreme weather events.

4) Poor maintenance:

A lack of proper maintenance can cause a roof to deteriorate more quickly, which can increase the likelihood of collapse. For example, a roof with clogged gutters or missing shingles can be more susceptible to damage from heavy rain or wind.

5) Excessive weight:

Roofs are designed to support a certain amount of weight, and exceeding this weight limit can cause the roof to collapse. This can happen if there is too much snow or debris on the roof, or if heavy equipment is placed on the roof without proper support.


In conclusion, roof collapse can be a catastrophic event that can cause significant damage and injury. While there are several causes of roof collapse, the most common include structural failure, water damage, age, poor maintenance, and excessive weight. Building owners can take steps to prevent roof collapse by ensuring that their roofs are properly designed, constructed, and maintained, as well as by addressing any issues as soon as they arise. It is important to recognize the signs of roof damage and to take action promptly to prevent further damage and potential collapse. By being proactive and taking necessary precautions, homeowners can help ensure the safety and longevity of their roofs.
