Kensington's streets are defined by white stucco-fronted Victorian terraces and grand mansion blocks, many of them in conservation areas. Their roofs typically combine pitched slate sections with flat roofs over bays, extensions and dormers, along with substantial leadwork at parapets and valleys.
Pitched roofs on this stock suit Welsh slate with Code 5 lead, while the flat roof sections common on mansion blocks are well served by EPDM, felt or mastic asphalt. Breathable insulation such as TLX Gold helps meet modern efficiency standards without compromising a traditional building's fabric.
