Building Envelope
Protecting your building from the British elements.
The building envelope is the barrier between the interior and the exterior — critical for thermal performance, weathertightness, and aesthetics. Meridian's envelope specialists work on everything from flat-roof commercial buildings to pitched slate roofs on heritage properties.
Roofing
We install and repair all types of roofing systems for residential and commercial properties across the UK. Our roofing teams are experienced in traditional pitched roofs using natural slate, plain tile, and interlocking profiled tiles, as well as modern flat roof systems including single-ply membranes (TPO, EPDM, PVC), cold-applied liquid coatings, and green roof build-ups.
