Roof refurbishment systems

for sustainable and long-lasting refurbishment of existing roofs


The Kalzip roof refurbishment concepts stabilise the healthy building fabric and provide decades of protection as a result. In addition to fulfilling the requirements for thermal insulation, Kalzip roof systems also achieve excellent sound insulation values. Thanks to their generally low weight, they are also predestined for large spans and the renovation of old roofs.

The advantages of roof refurbishment with Kalzip:

  • Highest corrosion resistance due to seawater-resistant aluminium base material
  • Durable, functional and virtually maintenance-free building protection
  • High degree of design freedom thanks to customised roof shapes
  • Economical, fast assembly
  • Mostly unrestricted use of the property during refurbishment
  • Rigid roofing

Sustainable roof refurbishment
Economical – long-lasting – safe

The advantages of roof refurbishment with Kalzip:

  • Corrosion-resistant, weatherproof aluminium alloy as the base material
  • High strength and low dead load
  • Resistant to ageing and durable
  • High cost-effectiveness due to easy, fast assembly
  • Flexibly adaptable to any floor plan shape and size
  • Suitable for warm and cold roofs
  • The system is non-flammable and resistant to corrosion and moisture

Roof refurbishment applications:

  • Flat roofs: Kalzip roof renovation systems can be used to renovate old and damaged flat roofs.
  • Shed roofs: Kalzip roof refurbishment systems are ideal for use on old shed roofs where the roof covering has become a problem area over the years.
  • Composite roofs: In older roofs with steel sandwich elements, the effects of weathering and ageing often lead to the ingress of rainwater through leaking transverse and longitudinal joints. Kalzip has sustainable and innovative solutions for cases like these.
  • Asbestos roof coverings: Kalzip can offer sustainable and cost-effective refurbishment solutions, particularly for roofs covered with corrugated asbestos sheets.
