3.2. Incorrect installation of underlayment, valley gutters and flashings (see Roof Inspection Report, page 22 ff.) The galvanized steel sheet underlayment has laps not located under the flat steel counter-battens leaving the laps exposed to water penetration. The construction of the valley gutters does not prevent water running into the unsealed battens. Water discharge occurs through the eaves damaging the whole of the soffit. Flashings to abutments and upstands are either non-existent or inadequate (see Roof Inspection Report, page 25 ff.)
