Many buildings you see on the street often have a similar roof. Metal, slate or concrete are some of the common materials used and effect the form and look of most modern roofs. But there are other types of roofs, some which aren’t so simple and more unique.

Sports stadiums often have retractable roofs to ensure that events are not affected by the unpredictable British weather, and great consideration has gone into their design and application. Roofs like this are easy to spot as they stand out on the skyline.

The roof is of unique construction due in part to the materials used to make it. They make use of a highly advanced fabric called PolyTetraFlouroEthylene (PTFE), regarded as the strongest known polymer, which allows the structure to remain light yet highly durable.

This allows the roof to be constructed in a manner which allows for it to move, whilst keeping its strength as the roof is positioned differently.
