Residential & Commercial Roofing

Build up Felt Roofing

Our Built up Roofing systems consist of two or more superimposed layers of a bitumen roofing sheet fused together by torch application method. This multi-layer system allows greater levels of defence against water ingress and damp.


The ideal membrane would combine a base of high stiffness and tension, with a low stiffness matrix to provide the most effective combination of characteristics to resist movement and effectively maintain waterproofing integrity.


Within these membranes, the materials consist of a reinforcement base of glass (or polyester coated) with oxidised or modified bitumen. This is a popular choice of roof covering due to the strong waterproofing and adhesive properties of bitumen. But, it is the nature of the reinforcing base that controls the strength and fatigue resistance.


There are many felt roofing systems available, such as “Torch-on” systems and “Cut to fall” insulation systems. The more common being Torch-on, which is a means of adhering membranes for built-up roofing.


Rooflight Replacement

Many buildings require a source of natural light and therefore have rooflights incorporated into the roof. Rooflights can be of various materials and design such as northlight glazing, domes and GRP translucent sheets.


Defective and ageing rooflights can often be the cause of roof leaks or insufficient light levels. We have many years experience replacing all types of rooflight with up to date systems. These include single skin and factory assembled insulated GRP rooflights (FAIRS), GRP and polycarbonate domes and multi-wall polycarbonate glazing systems.

Liquid Applied Waterproof Systems

Waterproof and Weatherproof coatings giving protection to all roof surfaces (asbestos, felt roofs, asphalt roofs, and also cast iron roofs and gutters. Instant waterproofing which can be applied even when it’s raining.


Clear coatings are also available for roof lights, which will withstand severe impacts.
