    What this document argues

    A 32-page product selector from a British roofing distributor, running through the flat roofing systems it stocks — GRP, liquid coatings, single ply, EPDM, torch-on bitumen, mastic asphalt, repair compounds — alongside insulation, trims, outlets, fixings, tools and PPE. Its genuinely technical content sits at the front: a deck-by-deck comparison of OSB, metal and concrete with the advantages and disadvantages of each (metal as a "lively deck" that changes how waterproofing must be detailed, concrete needing a long drying-out period before covering), and a cold-versus-warm-versus-inverted build-up comparison. A summary table sets fitting requirements, material cost and warranty length side by side.

    Why a contractor cares. The deck and build-up comparisons are a quick way to reason through flat roof trade-offs before specifying. The products, warranties and standards are UK-only.

    Why a public adjuster cares. Almost nothing. It is a merchant's catalogue with a 15-year warranty offer attached, it disclaims responsibility for its own technical accuracy, and it bears on no US coverage question.

    A summary written by the National Roofing Directory, not an extract. The work itself is SIG Roofing (UK builders' merchant / distributor)'s and is not reproduced here.
