Hybrid roofs are a modern roof construction method that combines some of the best elements of cold and warm structures. However, what does this mean, and when should you consider installing this type of roofing?
Here’s everything you need to know in our easy guide to hybrid roofs.
Cold roofs vs warm roofs
When discussing hybrid roofs, you’ll often hear roofers talking about warm and cold roofs, but what does this actually mean? The key difference is the way insulating layers are applied during the construction.
In cold roofs, roof insulation is applied between the rafters (in the voids between joists), compared to a warm roof, where it’s placed above each separate roof surface. A cold roof allows for more air circulation, but this can also lead to more cold air entering the roofing area where it’s not insulated.
By contrast, a warm roof is designed to keep the entire roofing structure as thermally insulated as possible. Warm roofs are often chosen for their thermal efficiency, but they can affect the appearance of the building with increased roof heights involved.
What are the benefits of a hybrid roof?
Hybrid roofs are sometimes referred to as ‘compact roofs’, combining the elements of both warm and cold roof construction. It means that most of the insulation is installed underneath the roof surface, but there’s less need for a thicker layer above as there’s a smaller area left for ventilation.
This has the benefit of being safer and more thermally insulating than a cold roof construction without the bulky appearance often created by the greater depth of warm roofs.
However, careful consideration needs to be taken for the suitability of this type of roof to ensure condensation won’t become an issue. That’s why it’s so important to consult an expert roofer about the best roofing for your property.
How to choose the right roof for your property
If you’re considering a new or replacement roof, always ask a professional roofer to assess the project to ensure you make the right choice. If you’re considering a hybrid roof, a condensation risk analysis should take place, thinking about the use of the building and humidity levels. They’re often chosen for low risk domestic roof projects in low occupancy properties.
Ask your roofer about the different types of roof insulation they use and what they’d recommend for the installation. It may be that a warm or cold roof would be a more suitable application, but there are options to reduce some of the downsides of each type of roofing.
They can also work closely with you to find solutions to suit your budget, reducing roofing costs.
