Henshaws work with the manufacturer Cromar for training in the installation of GRP Glass re-inforced roofing systems. This allows contractors to have a full manufacturer guarantee with their flat roofing systems. These come with a 25 year guarantee for GRP and a 10 year or 20 year guarantee for Flexiglass.
The latest contractors learn the techniques for fitting GRP roofs and work to gain their certification.
