Structural roof inspection reports consist of three parts:
- Observations. This is a description of what is actually observed on-site, such as the size of cracks, the extent of bowing or shifting, the condition of the roofing material and flashings, and other things that could be relevant to the problem.
- Interpretation. This is an explanation from an engineering standpoint as to what is causing the problem that is observed.
- Opinion. An opinion is given as to what needs to be done to assure the structural integrity of the building, including both eliminating the cause of the problem and repairing any damage done. This can range from “this building system is structurally intact and nothing further needs to be done” to extensive repairs, such as adding “sister” rafters
