Metal roofs are widely used across industrial, commercial, retail and public sector buildings due to their durability, lightweight construction and ability to efficiently shed water. Over time, however, weathering, UV exposure, ageing coatings and movement at laps and joints can affect waterproofing performance, creating the need for maintenance and refurbishment. Sika's liquid-applied waterproofing systems provide a seamless solution for the refurbishment of metal and asbestos cement roofs, helping to extend roof service life without the disruption and cost associated with full roof replacement. Liquid-applied membranes Sikalastic®-625 N and Sikalastic®-641 create a fully bonded waterproofing layer that can accommodate complex roof details, while Sika® Joint Tape SA provides reinforcement at joints, laps and areas of movement. Suitable for a wide range of roof refurbishment projects, these systems offer a practical solution for restoring weather resistance and long-term waterproofing performance.
