With both our in-house roofing team and the recent acquisition of Imperial Waterproofing Limited, arc Group can offer clients a truly comprehensive roofing service.  Our clients’ projects range from a single building  to national retail chains and industrial buildings.

Imperial specialise in complex roof designs, providing bespoke roofing solutions for the most challenging brief.

All Imperial systems are complete packages from membranes/coatings/metal panels through to flashings, maintenance-free edging details, specialist metal fabricating, penetrations, drainage, rooflights, walkways etc. Imperial can also add aesthetic and environmentally friendly treatments to the main roof itself such as green roof treatments.  Imperial is used to dealing with complex bespoke roof designs and our in-house team are happy to work with the architect to finesse the scheme to produce a practical solution.

Imperial can offer a roofing solution that is competitively priced and carried out to a high standard, offering everything from new roof installations and refurbishments to continuous maintenance programmes.

We’ll use our extensive experience in the industry to ensure your building remains operational during the works while minimising disruption and reducing costs.
