The terms Inspection and Survey tend to be interchangeable, there is a slight difference between the two types of roof or building assessments. Inspections are usually carried out to examine the health and integrity of the building fabric to ensure everything conforms to Current Building Regulations and is fit for purpose. This is normally a requirement for a property purchase, a lease agreement, if there is a legal dispute or for insurance purposes. A Survey is more in depth than an Inspection including carrying out flat roof core samples and measurements with the intention of carrying out a refurbishment project.
