Ten Most Common Causes of Commercial Roof Failure
The roof will wear out over the years for several reasons. The environment, foliage, and climate are big factors affecting your roof. Below are the most common factors that cause your commercial roof to wear. Assessment of these factors can help you better prepare and protect your roof for the long term.
Consider what weather the roof will be exposed to and if there are any pollutants. Are there any chemicals used in the area that may degrade or affect the roof? Were any chemicals used directly on the roof?
2) Structural movement
Roofs are known to expand and contract as the weather changes. This is especially common in areas that experience both hot and cold seasons. Check for defects such as blistering and cracking to identify if this has become a problem.
3) Biological growth
Does your roof have any growth such as algae or vegetation that can wear on the roof?
4) Not fixing problems promptly
When you notice problems in the roofing, do you fix them right away? Leaving them can allow the situation to get worse and more expensive to repair. It is not just the exterior roofing, you have to check the insulation for damage too. Debris collecting can also clog drains and allow for pooling water.
5) Forgetting about maintenance
The number one reason a roof needs to be replaced prematurely is a lack of regular maintenance.
6) Change in the use of the building
Is the building now used for something different? Changes in use can result in changes in condensation on the roof which impacts its longevity. These 6 factors will wear down a roof over time, and before you know it the roof is in critical condition. In addition to these, there are 4 other culprits that can cause immediate more problems that are just as bad. What causes immediate roofing problems?
7) Extreme weather
Lightning, hail, high winds, earthquakes, snow, and heavy rain.
