About Roof Overlay Systems
Roof overlay systems are built on top of an existing roof (after some preparation work) to provide a new insulative layer and a weatherproof outer protection. Not all roofs are suitable for an overlay system and only some roofing materials are able to be used as an overlay. GRP (fibreglass) is an excellent flat roofing material but cannot be used as an overlay, it requires brand new substrate.
We offer built up felt roofing which employs a 2 layer system which provides excellent insulation in addition to being very durable. This can be applied directly over existing felt roof making it a convenient and cost effective way to enhance a felt roof without the need for more major building works.
We offer excellent flat roof overlay systems with the following materials:
- PVC (single ply membrane)
- EPDM (rubber roofing)
- 2 layer felt
