Greenhous Vauxhall in Hadley, Telford, is a well‑established automotive dealership serving customers across Shropshire. As part of their ongoing commitment to maintaining a professional, safe and well‑presented site, the management team identified the need for a full refurbishment of the metal roof system on their showroom structure. Years of exposure to weathering and UV degradation had resulted in visible cut edge corrosion along the sheet laps, delamination of the original coatings and general deterioration across the roof surface. With the building forming a key part of the dealership’s customer‑facing environment, restoring its condition was essential.

Cladding Coatings was appointed to deliver a complete refurbishment using our 15‑year warranty system, designed specifically for metal cladding and corrosion protection. The project required careful planning to ensure minimal disruption to the dealership’s daily operations, as the site remained fully active throughout the works. A detailed condition survey was carried out to assess the extent of deterioration and confirm the most appropriate treatment approach. The inspection revealed widespread cut edge corrosion, weakened protective coatings and areas of rust where the substrate had become exposed. The 308m² roof surface showed clear signs of ageing, with faded coatings and compromised waterproofing integrity.

The client’s objectives were to halt ongoing corrosion, reinstate full waterproofing performance and secure a long‑term, warranty‑backed solution that would protect the building for many years. Appearance was also a priority, as the roof forms a prominent part of the dealership’s visual identity. Cladding Coatings developed a programme that addressed each of these requirements while ensuring compliance with all safety and environmental standards.

Preparation formed the foundation of the refurbishment. The roof was thoroughly cleaned using specialist equipment to remove dirt, moss, debris and any loose or failing coatings. This stage is essential for ensuring strong adhesion of the new system. Areas affected by rust were mechanically abraded to expose sound metal, creating a stable surface for priming and treatment.

The cut edge corrosion treatment covered approximately 62 linear metres of affected sheet laps. Each area was carefully prepared to remove delaminated coatings and expose the underlying corrosion. A rust‑inhibiting primer was applied to stabilise the metal and prevent further deterioration. The laps were then reinforced with a specialist sealing compound designed to provide flexibility and accommodate natural movement within the roof sheets. A durable topcoat completed the treatment, reinstating full protection and preventing future cracking or moisture penetration.

Following the corrosion treatment, the full roof coating was applied across the 308m² surface. The system began with a primer to ensure strong adhesion and compatibility with the substrate. Once cured, two coats of the high‑performance 15‑year system were applied. This coating provides exceptional UV stability, corrosion resistance and long‑term durability, ensuring the roof remains protected for many years. The application was carried out in accordance with manufacturer guidelines, and a final inspection confirmed uniform coverage and compliance with all warranty requirements.

Working on a busy automotive dealership presented several logistical challenges. Our team coordinated closely with Greenhous Vauxhall to schedule works around customer traffic, vehicle movements and service operations. Safety remained a priority throughout, with clear segregation of work areas and continuous monitoring of weather conditions to ensure optimal application windows. The varying levels of deterioration across the roof required adaptive techniques, particularly around heavily corroded laps, but our experienced technicians ensured each area received the correct level of preparation and treatment.

The completed refurbishment delivered significant benefits for Greenhous Vauxhall. Corrosion was fully arrested, waterproofing integrity restored and the roof’s appearance transformed. The building now presents a clean, uniform and professional exterior that reflects the dealership’s commitment to quality. The long‑term 15‑year warranty provides assurance that the roof will remain protected, reducing future maintenance requirements and safeguarding the asset for the foreseeable future.
Through meticulous preparation, specialist corrosion treatment, careful handling of the solar panel infrastructure and the application of our advanced coating system, we restored the roof’s performance and ensured durable protection for one of Telford’s leading Vauxhall dealerships.
