Tell me if this is a stupid question (I'm sure someone will!) but is it possible to replace the fascia boards around a flat roof without re-roofing? I have a flat extension roof, 3.5m x 4m with fascias on three sides. The roof is about 7 years old and very sound, no sign of problems at all, but the fascias have rotted - my guess is that they weren't replaced when the roof was done. If possible I want to have them replaced with uPVC without re-doing the whole roof.
