In recent years A2O have expanded in to the roofing sector to be able to provide a full envelope service. Commercial roofing is now a core part of our business, with a range of membrane, composite and green & brown roofing systems installed across a variety of sectors and building types.

We install industrial and commercial roofing systems for a wide variety of projects across the UK.

Our roofing work includes both new projects and refurbishment work, and we can also implement planned preventative maintenance programmes via our dedicated maintenance division.

Composite roofing

Composite roofing is a panel system whereby the metal profile outer sheet, insulation filler and internal liner are bonded together in one sheet. These panels are typically specified for large scale industrial and commercial projects, where long panel lengths allow for fast, efficient build programmes.

We regularly work with the following systems: Kingspan, Arcelor

Standing seam roofing

Standing seam roofing is a metal roofing system which involves the joining of panels above the flat of the roof with the use of non-penetrative clip systems.

These systems are lightweight and offer maximum design flexibility as they can be formed into complex shapes including tapers and waveforms, with many of them able to be roll-formed on site. Because there are no end laps and no external penetrations of the outer sheet, standing seam roofing provides optimum weather protection and requires minimal ongoing maintenance.

We regularly work with the following systems: Euroseam, Omnis Speedeck & Speedzip, Kingspan Kingzip

Membrane roofing

Membrane roofing involves the application of a flexible, durable weatherproof membrane. Single ply membranes are available in either PVC or flexible polyolefine (FPO) and can be laid to shallow falls as well as used to achieve complex roof shapes.

We regularly work with the following systems: Sika Trocal, Cefil, Bailey, Widopan, Proteus Liquid Applied Systems

Built up roofing

Built up roofing systems consist of an internal liner sheet and a structural grid system to create a cavity, this is filed with loose laid insulation in a variety of thicknesses to achieve the required u value. An external quality finished profiled top sheet forms the outer layer.

These systems are the most commonly used in the industry, which means they are readily available, resulting in short lead-in periods to site and a competitive price.

We regularly work with the following systems: Euroclad Elite, Omnis and Ash & Lacey
