Enduring legacy: The ageless appeal of mastic asphalt for roofing restoration
Mastic asphalt stands as one of the construction industry’s most time-honoured materials, having earned the trust of roofers across the globe for centuries. Its unmatched durability solidifies its status as a resilient solution, capable of withstanding the test of time.
Here, we delve into why mastic asphalt remains a compelling choice and explore how this traditional solution can meet the demands for sustainable construction while offering a design life that spans more than a century.
Making the case for mastic asphalt
Known for its remarkable longevity, mastic asphalt is among the most resilient construction materials. It boasts a rich heritage that dates back nearly 200 years with its first patent, although its use predates this period significantly.
Primarily composed of bitumen, limestone filler and aggregate, mastic asphalt is applied in a heated, molten form. This allows it to be moulded into any desired shape, contour or detail, resulting in a seamless, monolithic finish.
Its exceptional durability makes mastic asphalt a preferred choice for safeguarding the integrity of the United Kingdom’s most revered buildings. For conservation purposes, mastic asphalt is favoured for refurbishing historically significant structures, as it was the original material used in their construction. In fact, National Trust, English Heritage, Historic Environment Scotland and other public and private custodians of prestigious buildings frequently specify mastic asphalt for roof refurbishments.
In recent years, IKO’s mastic asphalt solutions have been selected for high-profile renovations at iconic sites such as Glasgow Cathedral, the Tower of London, Westminster Cathedral, and St Paul’s Cathedral. These projects underscore the material’s ability to preserve architectural heritage and offer protection against the elements.
