What is a Warm Roof?
A warm roof is a type of roof insulation that works by trapping air between the roof and the insulation. This trapped air acts as an insulator, preventing heat from escaping from your home or business. As leading warm roof installers, our roofs also consist of additional layers of insulation with a cover membrane on top that protects the insulation from weathering.

Your Local Warm Roof Installers
A warm roof is constructed in much the same way as a traditional roof, with the addition of insulation. At Southern Cross Projects Roofing & Waterproofing, we prioritise outstanding quality completed with the finest materials and a diligent construction process that we’ve perfected over the years.
Warm roofs typically have three layers for added protection to your property. Our process of constructing a warm roof starts by adding specific insulation atop the rafters, usually made from materials such as wool, cellulose or foam before the upper roofing deck is applied. This helps to create an airtight seal, preventing any heat loss.
Culminating with the outer layer, every roofing project we complete is sealed with a waterproof layer that protects your property from the harsh UK weather. Learn more about our high-quality waterproofing services.
Where are Warm Roofs Commonly Installed?
Warm roofs are most commonly found on commercial buildings, such as offices and warehouses due to their larger surface area as well as the need to retain heat at a cost-effective rate. However, they are growing in popularity among domestic properties.
Today, warm roofs are often installed on garages, outbuildings and conservatories. They’re also being used more and more for extensions and new builds to further improve energy ratings and reduce the overall construction times.
Warm Roof Insulation
We offer a range of insulation types that work in tandem with a warm roof to provide you with the best possible results.
Insulation can come in the form of rigid board, loose fill or spray foam. While we stock and install an array of insulations for a warm roof, the most common form we supply is our premium rigid board, as this offers the best thermal performance. It’s also easy to install and is renowned for its impressive durability.
We offer insulation materials such as mineral wool, polystyrene, and Polyurethane (PUR) in their various forms to achieve the best results for each project.
The high-quality fire-resistant materials we use for insulation help to improve safety ratings. When not installed correctly or if inferior insulation materials are used, it can have a detrimental impact on your home and the surrounding environment. This is why our qualified team of experts only use the best materials with flawless execution.
Warm Roof Vs Cold Roof
The main difference between a warm roof and a cold roof is the location of the insulation. In a warm roof, the insulation is installed on top of the ceiling, whereas in a cold roof, it’s installed beneath the roof deck.
Both warm and cold roofs have their respective advantages, but a warm roof is considered more thermally efficient, preventing heat from escaping through the roof. While being easier to install, as the insulation can be added during the construction process, warm roofs tend to be more expensive, depending on the materials used.
Our in-house, skilled team of craftsmen guarantee quality on every project, whether for a warm or cold roof. We adapt to your needs and can customise your roof to elevate your vision.
