The Problem

The 2,500m² metal roof at Aldi's Watford store was showing significant signs of deterioration, with its existing coating system reaching the end of its service life.

Corrosion had developed around the mid laps and cut edges, while previous repairs using various materials were beginning to fail. Deteriorating sealant around rooflight details and ageing fixings also presented potential risks of water ingress.

Without intervention, the roof would continue to deteriorate, potentially leading to costly sheet replacement and significant disruption to the business below.

The challenge was to address the existing corrosion and vulnerable areas, restore the roof's protective performance and provide a long-term solution without the need for a complete roof replacement.

Sealant had broken down across mid laps and tops of Skylights

Numerous repairs had been carried out using various materials

The fixings were a potential risk for leaks.

Corrosion has taken hold of the sheets around the mid laps and the cut edges.

How did we approach the challenge?

Working closely with Architectural Coating Solutions Ltd (ACS), Alltimes Coatings attended site to assess the roof's condition and understand the project's requirements.

Following the inspection, our technical team developed a detailed refurbishment specification, recommending the Advantage® Graphene Metal Roof Coating System, providing 30 years of warranted protection.

The specification focused on thorough surface preparation, treatment of cut edge corrosion, sealing of vulnerable overlaps and fixings, and addressing previous repairs before applying the protective coating.

Throughout the project, our Contractor Support team worked closely with ACS, providing technical guidance and practical advice to ensure the system was applied correctly and efficiently.

An incredible transformation using a range of Advantage materials to upgrade the look of the building but also offer 30 years protection

After the main roof sheets had been treated new cladded sheets were cut to size and installed over the tops of each Skylight

To highlight the covered roofsheets, the new sheets were treated using Alltimes Clad Enhance to protect the new sheets for 15 year

Delivering the Solution

The refurbishment began with a thorough pressure wash to remove dirt, salts and surface contamination. Corroded areas, cut edges, overlaps and fixings were then mechanically prepared, with repairs undertaken where necessary.

Advantage® Graphene Primer, Advantage® Adhesion Plus and Advantage® Sealant were used to treat and reinforce vulnerable areas, including cut edges, fixings, mid laps and rooflight details.

Once preparation was complete, Advantage® Graphene was applied across approximately 2,500m² of metal roofing at a specified wet film thickness of 200 microns, providing a long-term protective coating system backed by a 30-year warranty.

An additional safety consideration was incorporated into the refurbishment. New metal sheets were cut to size and installed over the tops of the existing rooflights to make these areas more visible. These sheets were finished in a contrasting colour using CladEnhance® , providing 15 years of protection to the newly installed sections.

The result was a striking transformation, restoring the appearance of the roof while addressing existing deterioration and providing long-term protection for the building.
