Commercial roofing in London

Roofing for blocks, freeholders and managing agents

A substantial roof project needs a clear definition of the work and the practical arrangements around it. We undertake roofing work and condition surveys for residential blocks and commercial properties. Send the building address, roof information and any existing specification so we can discuss the assessment needed for a quotation.

Flat roof renewal and waterproofing details

The waterproofing, deck, insulation considerations, falls and drainage all affect a renewal specification. Roof hatches, equipment, penetrations and upstands also need attention. Where further investigation or specialist design is needed, this should be identified before the scope is agreed.

Pitched roofs and associated work

For slate and tiled roofs, a renewal can include underlay, battens, ventilation, ridges, valleys and leadwork. Existing chimneys and rainwater details can be considered alongside the main covering. Share known defects early so access can be planned for the intended work.

Work around the people using the building

Tell us about occupied areas, access hours, shared entrances and building management arrangements. A proposed programme should take account of the roof, site access and relevant operational requirements. We discuss the arrangements before the work is agreed.

Reporting before committing to major work

A separately commissioned roof survey can help record condition, highlight limitations and explain recommended works. If a report is already available, share the relevant sections so quotations can be discussed against a clear scope. Avent also carries out roofing; a survey does not commit you to using us for the subsequent works.
