What Roofspace Solutions does

Roofspace Solutions manufactures, supplies, and installs off-site prefabricated roofing and whole house solutions for the UK housebuilding market, operating from a dedicated production site in Alcester, Warwickshire and a registered office in East Leake, Leicestershire. Its two core products are i-Roof, a BBA-certified panelised roofing system using storey-high aircrete and timber-engineered components that delivers a room-in-roof solution installable in a single day, and i-House, a complete prefabricated house shell combining H+H Celcon aircrete Vertical Wall Panels, prefabricated timber floors, and i-Roof to produce a watertight structure in approximately five days. The company employs 101-250 people and serves national and regional housebuilders (including Barratt Developments, Taylor Wimpey, Berkeley, Redrow, Lovell Homes, Mulberry Homes, Karm Homes), housing associations (Abri, Flagship), and mid-market developers through four regional contracts managers covering England.

The business model is hardware sales combined with optional turnkey installation services, with custom quote-based pricing and a six-week minimum lead time from call-off to installation. The company claims up to 40% faster construction than traditional methods, approximately five weeks of build time saved, and an 89.1% customer satisfaction score. Roofspace is a private subsidiary of Saint-Gobain Construction Products UK Limited, part of the Saint-Gobain Group, and joined the Off-Site Solutions division in 2018. Effective 1 April 2026, Roofspace Solutions operates under the Pasquill business as part of a consolidation creating a single supplier of structural roofing and flooring systems, with the i-Roof product continuing under the Pasquill brand.

Core offering

Roofspace Solutions designs, manufactures, supplies, and installs off-site constructed (MMC) structural building systems for UK housebuilders. Its two flagship products are i-Roof, a panelised roofing system with BBA certification, and i-House, a complete prefabricated housing shell using storey-high aircrete wall panels, timber floor cassettes, and the i-Roof. Products are made in a controlled factory in Alcester, Warwickshire, and delivered as either supply-only kits or full turnkey installation packages with regional contracts management.

Product overview

Roofspace Solutions operates under the Pasquill business and offers a portfolio of prefabricated structural roofing and flooring systems for the UK construction industry. The company provides two core off-site manufactured products: i-Roof (a panelised roofing system) and i-House (a complete prefabricated house solution combining Vertical Wall Panels, timber floors, and roofing). Both products are manufactured in controlled factory environments in Alcester/Warwickshire and installed by the company's specialist teams. i-House can be combined with i-Roof for complete property shells, or i-Roof can be installed independently on traditional builds.
