Roof Cassettes

Roof Cassettes

Our roof cassettes are precision-engineered offsite components, used in place of traditional on-site construction methods. With a design based on our in-depth industry knowledge and extensive experience, these innovative timber systems have been developed to meet the evolving demands of the construction sector, with rapid installation and a high percentage of pre-manufactured value.

Timber Cassettes

Our roof cassettes are designed by our in-house designers and fabricated in our upgraded cassette manufacturing facility.

The top of the cassette is finished in OSB, with a membrane to provide weather protection during installation.

The bottom of the cassette can be left open for site fix by client to finish with additional materials or factory finished to client specification.

Our roof cassettes are recognised as an innovation in custom-made, large format roof elements that deliver enhanced performance over and above standard building regulations.

I-Roof System

The I-Roof system from our sister company Roofspace Solutions provides a room-in-roof solution for 2.5 storey homes we supply fully manufactured walls and roofs complete with insulation and plasterboard. Our i-Roof system allows for a quick and easy on-site install, all managed from start to finish by our knowledgeable team.

Quality and durability

Our fabricated components are manufactured from the highest quality materials using state-of-the-art production equipment to rigorous quality control standards; ensuring long-term reliability and service life. All production processes are fully compliant with ISO 9001 (Quality), ISO 14001 (Environmental) and OHSAS 18001 (Health & Safety).

Technical due diligence

  • Moisture
  • Thermal performance
  • Wind uplift

All projects will undergo these theoretical calculations from which our technical experts will prepare manufacturing drawings for our manufacturing facilities to follow in purpose build brand new facility.

Design support included

This package includes additional design support:

  • Thermal calculations
  • Moisture risk analysis calculations
  • Wind uplift calculations
  • Structural design
  • Full drawing pack
  • Roofing system warrantee

Fixing and installation

As standard, the roof cassette is installed on top of the wall plate. Exact construction details will be confirmed during the design stage and approved by the client’s appointed principal designer.

Installation carried out by others. Pasquill will deliver direct to your site, as specified by a contractor who unloads/lifts off to either lift directly into position or store until ready for installation. The cassettes are unloaded (lift-off) as stacks or singly using pre-slung slings. Special instructions are required for storage onsite – the storage facility must be off the ground.

  • Impressive dimensional accuracy & reliable build quality
  • Dramatically reduced build times
  • Complete design, fabrication & delivery service


Roof cassettes are pre-fabricated roofing components, including structural elements, insulation, and other necessary materials. They streamline the construction process by offering a ready-made solution for roofs.

A timber cassette system involves the use of prefabricated timber components in construction. It includes structural elements like beams and panels, promoting efficiency and precision in building projects.

Yes, proper roof ventilation is crucial. It helps regulate temperature, reduce moisture, and prevent mould and decay. Adequate ventilation contributes to the longevity and efficiency of the roof.

Yes, a roof membrane is essential. It is a waterproof barrier, protecting your roof from leaks and water damage. Membranes enhance the roof’s longevity, providing an extra layer of defence against weather elements and contributing to overall structural integrity.
