In hot climates and in homes that use air conditioning systems, roofs that reflect heat and keep the home cooler are best. However, here in the UK, the most energy-efficient types of roof are those that keep the cold weather out and don’t allow heat to escape and therefore reduce the need to have the central heating on as often. We explore some of the best options below.
One of the most energy-efficient roof types is clay tiles. They have great heat resistance and thermal insulation and air can circulate underneath the tiles, giving them cooling properties. In addition to this, clay tiles can be recycled or reclaimed meaning they are a sustainable choice of roofing material.
Slate tiles or shingles are an energy-efficient, natural material that, like clay, can be recycled or reclaimed, making it an eco-friendly choice. Slate also has natural weatherproofing properties such as low water absorption and it is completely fireproof, making it an incredibly safe choice of roof.
A metal roof is an environmentally friendly, energy-efficient type of roof that is especially resistant to wind and other extreme weather due to its structure of interlocking panels. In addition to this, the top surface of metal reflects heat, leaving the underneath cool, which is useful for homes that have high air-conditioning or cooling bills.
Asphalt is a durable and affordable material that also has fewer leak problems than other roofs. Energy-efficient asphalt shingles have granules that reduce heat absorption, making them one of the most energy-efficient roofing materials for hot climates.
Cedar has great insulation properties as it naturally expands and contracts as the temperature changes. This allows the home to cool in the warm months and retain heat in the colder months. As a natural material, cedar shingles have great weather resistance and are less susceptible to moss growth, which can lead to weaknesses in the roof that could allow water to ingress.
While technically solar panels are not a roofing material, having them installed on your roof gives you a renewable source of electricity, meaning your central heating and energy bills should be lower.
Make sure you have good insulation
No matter what type of roof you have, its energy efficiency will be very limited if you do not have the proper insulation beneath it.
There are a few different insulation options available and choosing the right one will drastically improve how energy efficient your roof and home are. Roof insulation is often made from materials such as fibreglass, mineral wool, polystyrene, plastic fibres or natural fibres, and it comes in a few different forms such as:
- Rigid insulation boards
- Blanket insulation
- Loose fill insulation
- Spray foam roof insulation
- Spray foam roof insulation
- Structural insulated panels
The type of roof that is the most energy-efficient for your home depends on your heating and/or cooling needs. If you spend a lot heating your home, you need a roof that prevents heat from escaping, and if you regularly need to cool your home, you need a roof that reflects heat. Just as important as the roofing material itself though, is having adequate insulation material.
