Are you tired of replacing your roof every few years?
Imagine a durable roof that could last as long as your house. Bell Asphalt Co offers mastic asphalt roofing services in London for homes. Mastic asphalt offers unparalleled longevity, outlasting traditional materials for decades. There are no more leaks or replacements, just peace of mind and a beautiful, weatherproof roof that protects your home and your family.
Asphalt is a surfacing material laid using a timber float. As a mastic asphalt roofer, we use mastic asphalt roofing systems, which are a durable waterproofing solution for flat roofs. They are also used for basements, foundation floors, pavements, parking lots, and bridge decks.

At Bell Asphalt Co, our mastic roof service protects the city’s dynamic climate.
How We Use Mastic Asphalt Coating for Roofing
We use mastic asphalt for roofs because of its exceptional lastingness and waterproofing capabilities. Its unique properties make it an ideal choice for various applications in your home or building. So we use and suggest it to prevent water penetration, safeguarding your property from leaks and moisture damage.
Mastic asphalt is naturally black in color and becomes pliable when heated to approximately 254°C.
The heated asphalt is carefully placed into buckets and transported to the work surface. We apply it to the designated area with a purpose-made timber float and spread it to match the existing levels. The two-coat process ensures optimal coverage and a smooth finish. The asphalt’s molten form enables it to be effortlessly dressed around roof lights and pipes and creates a watertight seal around even the most complex architectural elements.
Where Mastic Asphalt Roofing is Perfect
At Bell Asphalt Co London, we have completed projects related to asphalt for the roof. From that experience, we understand when and where to use mastic asphalt.
- For Listed Buildings: it is used on the porches and box gutters of Georgian terraces, as well as the roofs of stately homes, churches, and cathedrals.
- For Council Buildings, Access Decks, and Bridges: Local authorities apply mastic asphalt to waterproof civic centers, guildhalls, and access decks in housing estates, particularly in London. It’s also common on car park decks.
- Tanking, Lift Pits, and Basements: Mastic asphalt is used for tanking in basements and lift pits due to its resistance to water penetration and durability. A tanking-grade asphalt product is recommended for these applications.
Our Typical Mastic Asphalt Roofing build-ups
Our most common specified build-up is the warm roof. IKO’s Permaphalt is a polymer-modified mastic asphalt product. We use mastic asphalt for walkways, insulated warm roofs, uninsulated cold roofs, and inverted/green roof configurations.
Warm Roof Build-up:
A warm roof features insulation above the structural deck but beneath the waterproofing layer. It requires a minimum fall of 1:80, ideally 1:40, for proper drainage. The build-up typically includes a solar reflective paint or chippings finish for UV protection and aesthetics. A separate vapor control layer is important to prevent moisture accumulation. The structural deck can be constructed from concrete, timber, or metal decking, providing a solid base for the warm roof system.
Inverted Roof Build-up:
An inverted roof configuration positions the insulation above the Permaphalt membrane as a protective layer. The design offers thermal stability, shielding the membrane and structure from extreme temperature fluctuations. A separate vapor control layer is unnecessary, and drainage falls may be omitted. This configuration proves ideal for insulated balconies and rooftop terraces, providing a durable and functional solution.
Complete Bond Roof System:
The Full Bond Roof System utilises a fully bonded polymer-modified mastic asphalt membrane, eliminating lateral moisture tracking through a torch-on underlay bonded to the concrete structure. The BBA-certified system boasts exceptional fire performance (BS 476: Part 3: FAA) and is ideal for inverted flat roofs, podiums, green roofs, and roof gardens, offering a robust and versatile waterproofing solution.
