    Remove and fit soffit ventilation or over-fascia ventilation or if they are too high up the roof. lower them.

    Replacing with over fascia or soffit vents won't give the desired result. The soffit vent is low level ventilation and the slate vent provide high level ventilation. Combined the two create a cross draft through the roof space allowing plenty of circulation. If the soot is coming in and if the chimney is on one side of the roof put the roof vents on the opposite side of the roof so the ridge line shields it from smoke. Failing this maybe a ventilated ridge system would work better. If you go down the vented ridge path explain your problem to the supplier and ask their advice because changing the ridge is a good bit of work.
