Standing Seam
Exall Group are specialist standing seam roofing contractors serving London, Essex, Surrey and Kent. As Kalzip approved installers, we design and install premium standing seam systems for commercial, industrial and architectural buildings of all scales.
Standing seam roofing is the premium choice for commercial properties requiring exceptional weather resistance, longevity and architectural finish. With fully concealed fixings, precision-formed interlocking panels and zero exposed fasteners, standing seam systems offer outstanding structural integrity with minimal maintenance requirements over their lifespan.
We work with the industry's leading systems including Kalzip, AshZip and other aluminium and steel standing seam profiles — available in a wide range of colours, finishes and panel widths to suit any architectural requirement. Whether you need a full roof replacement, a new build installation or a complex curved or tapered profile, our experienced team delivers every project to the highest standard.
Recent standing seam projects include a 700m² AshZip installation in Chertsey, Surrey and a Molesey FC clubhouse roof in East Molesey — both completed on programme and to manufacturer specification.

Frequently Asked Questions
Standing seam is a metal roofing system where panels interlock via raised seams that run vertically up the roof. All fixings are concealed within the seam, giving a clean architectural finish with no exposed fasteners. It is one of the most durable and weather-resistant commercial roofing systems available, with lifespans exceeding 40 years.
Standing seam roofing costs vary depending on the size of the project, the system specified, and access requirements. As a guide, commercial standing seam installations typically range from £150 to £400 per m². Exall Group provide free no-obligation surveys and detailed quotations for all projects across London and the South East.
A correctly installed standing seam roof will typically last 40 to 60 years with minimal maintenance. Aluminium systems such as Kalzip are particularly long-lasting and highly resistant to corrosion, making them ideal for commercial and industrial buildings.
