What is a Flat Roof
Capping System?
A capping system is an aluminium finishing system installed along the top of parapet walls, upstands, and roof edges on flat-roofed buildings. Its primary function is to cap the exposed top of the parapet, preventing rainwater from entering the wall structure from above – one of the most common points of water ingress on flat-roofed buildings. Without a properly installed capping, rainwater can soak into the brickwork and mortar joints of a parapet wall, causing damp, spalling, and structural deterioration over time.
Modern aluminium capping systems are made to measure, lightweight, corrosion resistant, and designed to provide a clean, professional finish to any roofline. At The Flat Roofing Company, we fabricate and install bespoke capping systems to cover parapet details as part of our flat roofing installations, ensuring every edge and upstand is fully protected and aesthetically finished. As demonstrated on our Seven Acres project in Surrey, our capping work is made to measure to cover parapet details with a great aesthetic finish, including bespoke fascia metals on the face of larger properties.

Capping Systems from The Flat Roofing Company
The Flat Roofing Company installs bespoke aluminium capping systems as part of our flat roofing projects across Dorset, Hampshire, and Wiltshire. We fabricate capping to measure to cover parapet details with a precise, weathertight finish. On larger projects, we also install bespoke fascia metals on the face of the property to complete the roofline detail and provide a polished, consistent appearance.
Capping systems are typically installed as part of a wider flat roofing project rather than as a standalone service, ensuring the membrane, upstands, and capping all work together as a fully integrated waterproofing system. Our team carries out all metalwork in-house and takes care to deliver a clean, accurate finish on every installation. All our work is backed by a 20-year materials warranty and a 10-year insurance-backed workmanship guarantee.
