Whether we’re talking about residential or commercial roofing, deciding on which material to use will determine its durability, how well it protects the structure from outside elements, and how controlled the internal temperature of the building is. Today, an increasing number of homeowners and building owners prefer energy-efficient roofing options, as these types of roofing allow them to lower the amount of money spent on their energy bills.

More than just focusing on the aesthetic value of the roofing material, people are becoming more conscious when it comes to the sustainability of their homes and their buildings. We look into the three types of roofing that are more energy-efficient than your standard roofs, and we discuss how they can benefit your home or business.

 Metal Roofing

Mostly used for residential homes, metal roofs are ideally used in warm weathered regions. Because metal roofs are made from thin materials such as copper, steel, and aluminium, they are less likely to absorb and retain heat from the sun. In fact, they reflect the sun’s damaging rays, which reduces the heat of the building beneath. From an environmental perspective, metal roofing is recyclable, which means that when your roof’s life runs out in twenty years’ time, you can still put the materials to good use elsewhere.

If you choose metal roofing, it’s best to stick to light colours, as they reflect solar energy and heat which contributes to a cooler and more comfortable home. Kiwis can take advantage of this during the warmer months of January and February when temperatures rise considerably. Instead of relying on air conditioners to cool down your space, choose a roof that maximises ventilation and temperature control. This reduces your energy consumption, which is environmentally friendly, and can help cut your energy bill in half. Metal roofs are also sturdy yet lightweight, and very long-lasting. This reduces your repair costs in the long-run, and make for a roof that is incredibly easy to maintain the whole year round.

Concrete Roofing

An increasingly popular option is concrete roofing. Concrete roofing is best utilised in areas that experience stronger winters and colder temperatures, as they are strong and heavy (and therefore difficult to move once laid). Concrete cement is mixed with fibrous reinforcement to strengthen the tiles, so the roof lasts longer and therefore reduces waste.

Due to this special mixed material, concrete roofing can withstand snow accumulation and excess weight. As an extra measure, concrete tiles coated with enamel help to trap heat, thereby contributing to greater energy efficiency. The substance can be broken down and reused, or biodegrade cleanly when thrown away, so it’s a very green option.

Concrete roofing can take the form of many roof types such as shingles, shakes, or tiles—making it all the more versatile! Even though concrete roofs require a studier roof deck because of the weight, and a waterproof membrane to protect the roof from ice and water, their durability and energy efficiency is without a doubt among the best.

Tile Roofing

Another energy-efficient roofing material is tile. Usually made from clay, concrete and ceramic, tiled roofs create a considerably more comfortable dwelling, as they help trap heat during cold months and keep the interiors cool during warmer months. Their outstanding thermal performance provides a second layer of insulation, thereby reducing harmful energy consumption. An extra helpful tip is to coat your tile roofs with light coloured paint, as it can help reduce heat absorption by reflecting the sun’s rays.

  • Clay tiles are recommended roofing material to homes in warmer areas as they can’t withstand hail and snow as well.
  • Concrete tiles, on the other hand, are good for any house regardless of location.
  • Ceramic tiles are stylish, and boast an excellent thermal performance as they are not conductive.

All three kinds of tiles are able to be repurposed if they are damaged, or biodegradable if thrown away. In combination with the reduced energy consumption, these make for a highly sustainable option.
