Condition Reports & Defect Documentation

We provide clear photographic condition reports highlighting defects, deterioration, and areas requiring attention. Reports are used to support maintenance planning, surveys, pre-purchase, and funding or conservation decisions.

Our reports are designed to be clear, visual, and easy to understand.

  1. We begin with an aerial overview image to divide the roof into clear sections.

  2. Defects are then labelled using architectural-style references (e.g. A1, A2) and supported with high-resolution images and close-ups.

  3. The final report provides clear visual evidence to help surveyors, contractors, and property owners understand condition and prioritise repairs.
