Warm roof conversion puts the insulation above the structural deck on flat roofs, eliminating cold bridging and condensation risk. For Witney extensions, garages and dormers with old felt or worn EPDM, a warm-roof rebuild is often the right answer when the covering needs replacing anyway — and it brings the roof up to current Part L without losing internal headroom.
Why convert to warm roof in Witney rather than just recover?
Warm roof eliminates cold bridging, condensation and ventilation faff in one go. If the covering needs replacing anyway, the additional cost over a like-for-like recover is small relative to the lifetime benefit.
Does it raise the roof height?
Yes, typically by 120–180mm. Worth checking neighbour overlook, building line and any boundary issues at survey stage.
How long does the new covering last?
EPDM and single-ply both carry 20+ year manufacturer warranties. Realistic working life is 30–40 years.
