Roof Ventilation

We have recently carried out a Defects Analysis Report on a flat within a block located in Redhill where there is a central flat roof.In between the roof timbers beneath the felt and decking there is insulation with an air gap above. This gap requires ventilation to dispel moisture laden air which can rise, especially from the bathrooms. Condensation issues are occurring within the property and void. It is discovered that the ventilation provided by the developers was inadequate.

The photographs clearly show that an attempt was made to provide ventilation; however, it was totally inadequate which is going to result in the partial re-roofing of this block of flats causing great inconvenience. The flats are only 6 years old and this clearly shows the importance of a survey to identify these issues before purchase.
