One of the cheapest ways of installing a new roof/wall as the existing structure is used as a fixing point.
Better roof safety/water and air sealing compared to older products.
Reduced labour requirement.
Lower cost of transport/disposal as the existing roof/wall isn't removed.
Minimised disruption to the occupants/building.
Carried out relatively quickly when compared to stripping/re-sheeting or installing a new roof/wall.
Increased thermal performance and energy efficiency due to additional insulation.
Optional rooflights offers a natural lighting system aiding energy efficiency while reducing your carbon footprint.
Can be carried out on an occupied building.
