You are hiring a Professional Building Consultant/Home Inspector. When you hire a building consultant/home inspector, you are hiring an experienced professional who has training and experience in the building industry. It is the job of the consultant to not only evaluate the condition of the house's major systems and structurals, but also to evaluate how these systems are working together and identify areas that need to be watched, repaired or replaced.

Your home consultant will give you the "Big Picture" analysis of the house.  If the building consultant identifies the need for a costly, detailed analysis of any of the home's systems or structural components, the inspector will recommend the appropriate professional, which may be an experienced engineer or a qualified licensed contractor or specialty tradesman with expertise analyzing that particular system or structural component. The need for this kind of expensive, detailed analysis is rare.
