AAC Waterproofing – Specialist Flat
Roof Installers

We are a flat roofing specialist, based in North Wales and operating primarily across North Wales and the North-West of England, but with ventures further afield across the rest of Britain according to the needs of our national clients.

Drawing on over forty years of flat roofing experience, we have evolved from our earlier days as mastic asphalt and bituminous felt contractors into specialist cold-applied system installers, particularly single-ply membranes and liquid-applied waterproofing. We are Approved Installers for Protan, Sika Sarnafil and Prelasti Systems (EPDM and/or Liquid-applied systems)

We operate in both the refurbishment and new-build sectors and our regular client base includes commercial and industrial clients, property developers, utilities, bespoke residential developers, and main contractors.

All of our operatives are fully trained in the systems which they work with, as well as general construction-related training, and our supervisors and managers have the relevant CITB site supervision qualifications (SSSTS).

To complement our flat roof waterproofing installation services, we also supply and install green roofs, and have completed many stunning examples throughout the North-West.
