Sustainable Lightweight Roofing Solutions

Sustainability has become a prerequisite of the modern renovation project. Government Standards require a particular level to be reached by existing homes, and various points need to be considered at each stage of the project, including stages prior to the main installation.

Much has been made about the impact on the environment by cars and other motor vehicles and the larger the building project, the greater the weight of the roof. Traditional materials such as slate or clay can become very heavy in bulk so will require multiple lorries - and all of the co2 emissions that go with them - just to get the roof to site. One way to resolve this issue is to specify a Metrotile Lightweight Steel Roofing System, because each Metrotile profile weighs just a fraction - up to one seventh - of slate or clay. This means the lorries used to take the roof to site could carry seven times as much Metrotile roofing as the other materials, or cut emissions by a seventh by requiring just one seventh of the transport requirements.

As for the projects themselves, HA’s are often bound by Government regulations to ensure older housing stock is maintained to decent homes standards. An example of this includes stock such as non-traditional homes - properties the general public may describe as ‘prefabs’. As many of these homes are still housing people decades after the end of their expected shelf life (mainly thanks to frequent renovation projects) it is important that standards are maintained. A Metrotile roof on these properties has many benefits (including reduced weight on the supporting structure) but the most significant here is the increasing of u-value. In Doncaster, Metrotile Roman was used on a close of Hawksley Bungalows that, in coordination with full outer envelope renovation, boosted the property insulation to the point where residents were seeing obvious reductions in energy bills.

Another way to reduce energy bills is for your home to generate it’s own energy via Metrotile’s Photovoltaic Panels. This was used to great effect on BISF properties in Maesteg, Wales. Metrotile offers both integrated and retrofit options, so if the Photovoltaic system can’t be budgeted for initially, It can certainly be installed further down the line.

What about decades into the future, when the roof has reached the end of its natural life? Well, as Metrotile roofing is pressed from the highest quality steel, it’s fully recyclable, continuing the trend for sustainability at every stage of the product’s life.

Metrotile has also achieved ISO14001 for its state of the art wastewater recycling system at its manufacturing plant in Tongerun, Belgium.

Each Metrotile roof is backed by an industry-leading forty year guarantee. For more information, visit or follow us on Twitter via @metrotileuk.
