Roofing Adhesives
(2 Products)Roofing adhesives in this range are solvent-based bituminous compounds formulated for bonding roofing felt to metal, timber, and concrete. Designed for cold application, these solutions provide a tough, high-strength seal for three-layer felt systems and lap joints without the need for hot bitumen or naked flames.
Understanding Roofing Adhesives
Roofing adhesives in this selection utilise oxidised bitumen dissolved in a solvent carrier to create a strong, flexible bond between roofing membranes and structural substrates. Unlike hot-applied alternatives, these cold-applied adhesives eliminate the safety risks associated with heating equipment and torches, making them suitable for both professional trade use and DIY repairs.
The primary function of these compounds is to secure roofing felt to surfaces such as asphalt, concrete, and timber decking. Once the solvent evaporates, the adhesive cures to form a tough, black interface that not only bonds the materials but also acts as a secondary waterproof barrier. This dual action ensures that even if moisture penetrates the upper layers, the adhesive layer maintains the integrity of the roof structure.
Material Range
- Cold-Applied Bituminous Adhesives: Solvent-based bonding agents designed specifically for securing roofing felt. These heavy-duty adhesives, such as Everbuild Black Jack Roofing Felt Adhesive, are brush-applied and provide high initial tack, allowing for the effective installation of felt systems on flat and pitched roofs. They are also suitable for use as a cold gritting adhesive to bond mineral chippings to the final layer of a felt roof.
Performance Benefits
- Safety and Ease of Use: Cold application removes the fire hazards associated with hot bitumen pots and gas torches, simplifying site safety requirements.
- Dual-Action Performance: Functions as both a high-strength bonding agent and a waterproof seal, enhancing the overall weather resistance of the roofing system.
- Substrate Adhesion: Demonstrates excellent adhesion to common building materials, including timber, concrete, fibre cement, and metals, ensuring a secure hold in diverse construction environments.
Typical Applications
- Felt Bonding: Securing successive layers of roofing felt to timber decks or concrete roofs in built-up felt systems.
- Lap Sealing: Sealing overlaps between sheets of roofing felt to prevent wind uplift and water ingress.
- Cold Gritting: Bonding protective mineral chippings or grit to the top surface of a finished felt roof to provide UV protection.
Specification & Standards
- ISO 9001: Manufactured under strict quality management systems to ensure consistent viscosity and adhesive performance.
- Manufacturer Specification: Formulated to meet the specific bonding requirements of standard bituminous roofing felts.
Related Materials and Construction Uses
These adhesives are fundamental to the installation of built-up roofing systems, working in conjunction with breathable sheathing felts, underlays, and mineral-surfaced cap sheets.
They are applied directly onto structural decks, including marine plywood and OSB, or onto primed concrete surfaces.
For optimal longevity, these adhesives are often used alongside solar-reflective paints or bonded mineral chippings, which protect the underlying bitumen from thermal degradation.
