Our Services
Flat Roofing
We provide a full refurbishment or repair service on existing buildings or provide completely new flat roof built up systems on new build projects. All roofing works carried out are completed with the clients remit at the forefront of our best solution based approach. Whether it is a purely waterproofing exercise or the need to upgrade the roof to comply with current building regulations we will find the right product and specification to suit your requirements.
Systems include the latest Flame Free applications, Single Layer Waterproofing Technology, and Traditional Torch on Systems.
We offer Design, Workmanship and IKO Material Guarantees of up to 30 years.
Liquid Waterproofing Applications
Where the requirement for a more flexible approach is needed in flat roof applications, we will put forward the latest in Polyurethane Coating Systems to enable the waterproofing of difficult roof areas that may have a lot of roof mounted plant or air conditioning units.
These products will still offer 10, 15, and 20 year guarantees and can be incorporated with fully insulated systems if required. The application of coating systems also lends itself to pitched corrugated roofs such as asbestos cement or metal cladded roofs. It has been particularly successful in the rejuvenation of metal cladded walls on retail, factory, and warehouse units where the original plastisol or polyester coating has weathered or failed. This prolongs the life of the building and also refreshes the appearance as if it were new.

We offer a full cladding service including provision of new composite roofing systems, secret fix designs, and retro fit over cladding to existing roofs, and installation of new gutter liners.
The inclusion of insulation quilt/wool or PIR/PUR composites is offered as part of the design criteria where required and replacement/upgrade to Step Safe (non fragile) roof lights.
