Key considerations for commercial roof design

If your commercial property needs a new roof, it can be easy to simply choose the first option presented, or available. After all, getting your business back up and running in the shortest amount of time is essential. But failing to plan for the specific needs and requirements of your building can be detrimental. In fact, it could end costing you more money in the long run. So working with a professional team, like us here at Enviroply Roofing, is essential. Especially if you want along lasting roof that will be suitable and safe for your individual property. This is because, as professionals, we take into account the key considerations for commercial roof design. So what are these? And why are they important? Well, this is our guide to everything you need to know about effective commercial roof design.


Key considerations for commercial roof design

To make sure your roof design will be suitable for your property, there are some essential details to bear in mind, and design around. These include:

  • Dealing with water
  • Wind load
  • Durability


Dealing with water

Commercial roofs need to be able to deal with the issue of water. In the North West especially, we see a large amount of rainfall. For any roof, this can present a challenge. As many commercial roofs also have flat roofs, this can present an additional concern. As a result, all commercial roofs should be designed to deal with potential water issues in a number of ways. This can include:

  • Falls for flat roofs- Flat roofs should never be designed to be flat. Instead a small gradient should be created to allow the water to run down and into the gutters and drains, away from the roof. This can prevent ponding and standing water.
  • Gutters and draining- Draining options suitable for the individual roof will need to be considered, to ensure that the water can be carried away safely. These will also need to be accessible for maintenance, as blocked drains can cause a range of potential problems for your property.
  • Blue roofs- Blue roofs are a different design completely, as instead of trying to remove the water as quickly as possible, a blue roof will store some of the water, and release this slowly over a period of time to prevent flooding in urban areas.


Wind load

One of the key considerations for commercial roof design should always be the wind load. For any commercial roof, it is essential that the roof is designed with the capability to withstand the wind, and uplift. A roof that is not prepared for the strongest potential wind uplift will become damaged during any storms or windy weather. As a result, wind load calculations are necessary to help determine exactly how to install the new roof, and the amount, and quality of roof components, fixings or ballast necessary.



In addition to the above, any roof installed on a commercial property needs to be durable. The roof will need to last for a long period of time, without being damaged from debris, animals, the heat or light of the sun, or any heavy weather. Single ply roofing membranes can offer this level of durability.
