When thinking about the maintenance of your roof, the effects of wind uplift should be an important consideration. The potential impact of wind uplift will be at the forefront of the thoughts of designers and planners when developing or modifying a property, as it poses great risks and the possibility of severe damage.

Understanding wind uplift

When high levels of wind come into contact with a structure, the significant amount of up pressure against the building pushes air upwards creating wind uplift. At the point that pressure builds underneath and reaches a level greater than the pressure being created above, uplift can occur.

Other additional factors can also contribute to wind uplift and the impact on your building. Structure height and the height of those in the immediate vicinity can affect the level of wind uplift that occurs.

The types of doors on your premises can also have a bearing; structures with large openings such as a hangar or warehouse may be at much greater risk than a building with standard entrances and doorways.

The effect on your roof of wind uplift

High winds will conduct a serious examination on the integrity of your roof. When wind uplift occurs it will do so with great force, exposing any evidence of weakness. The worst case scenario is that your roof could potentially be completely separated from the main structure it adorns.

If there are cracks and openings on your roof this will aid the build up of air pressure within the building, adding to the already powerful uplift effect. This can led to the roof membrane being damaged, forcing screws to be pulled out and other materials being compromised.

It’s possible that the impact of wind uplift on your roof might not be detected initially, causing further problems down the line. If left unnoticed long enough it could even lead to the need for a full roof replacement.

Protecting your roof

Understanding wind uplift and the specific requirements of your building are essential in determining the correct roofing system for the task. It’s important to investigate what wind loads will be expected and then selecting properly tested materials ahead of installation.

Ensure also that the professionals installing your roof have experience and knowledge of wind uplift issues, they should be able to evaluate and best determine the protection your roof and building need. They should be able to pick up on any existing problems and recognise the reasons why these issues exist.

As with everything connected to your roof, it’s important to fully understand your specific requirements and use contractors who are qualified to complete the work. Ongoing maintenance and checks are an absolute must if you are to prevent costly repairs whilst ensuring the continued safety of your building or premises.
