Strength/ Durability

Mastic asphalt is a very strong material and can actually be made even stronger if stone chippings are utilised during the installation.

Mastic asphalt is much more versatile and flexible than many people realise. Once it is properly installed it even produces a monolithic membrane which gives it greater flexibility. This also makes it easier for the asphalt to be installed across different roof styles and shapes. Unlike some other roofing materials, mastic asphalt isn’t overly affected by shape making it a versatile material many homes can use. 


Mastic asphalt just like regular asphalt is based on bitumen and as you may know, that is not a material well known for its sustainability. However, mastic asphalt does have some benefits that make it more sustainable.
