Our Three Main Installation Processes

Ballast Installation

This process involves the membrane being loose laid, but all still heat welded together, then having a ballast placed on top (ie timber decking, flags or stones). This is a cost effective way as there is less labour time and you also don’t have to pay for fixings or glue to adhere the membrane to the roof structure. It is usually recommended for small jobs such as balconies and other smaller domestic roof projects.

Mechanically Fixed Installation

This process involves the membrane being laid out on the roof and it being fixed around the perimeter of the sheet with washers and fixing (to wind uplift calculation specs), the next sheet is then placed over the washers of the previous sheet and heat welded together by a competent person. This can be used on various sized projects.

Fully Adhered Installation

This involves all membrane runs being adhered to the substrate, and subsequent membrane sheets lapping over and fully heat welding the lap. This can be used on any project.


“Enviroply carried out a first class job fitting approx 150m2 of Sarnafil roofing in difficult winter weather conditions, and the results are excellent. They were always ready to adapt to little design changes and were great to work with. We are delighted with the results and we have already recommended them to others. Stuart Treasurer, Wirral. ”
