Roof Ventilation and Listed Building Consent
Roof ventilation installations on listed buildings require consent as they alter appearance. Work must be undertaken without disfigurement to the roof, using manufactured items or traditional designs, with trade literature submitted to establish precise specifications.
The provision of roof ventilation will normally require listed building consent as it is likely to alter the appearance of the building. Where such work is proposed it should be undertaken without disfigurement to the roof, so thought will be required before deciding on a suitable method. There is a wide range of manufactured items to choose from. If it is the intention to use a standard item then it will be helpful if a section of trade literature is submitted with the listed building consent application in order that the precise item type, material, colour etc. can be established. An alternative is to copy the design of traditional ventilators.
