    One definition of inspect is "to view closely and critically."In building construction the term "inspection" can encompass manyother terms: completeness, code compliance, quality assurance, andas specified are just a few that come to mind.

    This guide is based on the assumption that the roof underinspection has been properly installed by well trained, experiencedsheet metal craftsmen under the leadership of a qualified customsheet metal roofing contractor. In new construction it is furtherassumed that a knowledgeable individual who had a role in thedesign of the roofing system— such as the architect or generalcontractor—inspected that the roof was installed and completedaccording to the original design intent.

    This guide should provide an individual who is NOT a roofingexpert sufficient guidance to inspect an existing roof on alogical, periodic basis. The inspection can determine ifmaintenance is required beyond cleaning debris from elements of aroofing system to renewing caulking that has aged to the point offailure. If more detailed and involved maintenance is required,then a professional, qualified custom sheet metal roofingcontractor should be called in.

    The sources for the information contained in this Guide are:

    • Architectural Sheet Metal Manual

    • Residential Sheet Metal Guidelines

    • Standard Practice in Sheet Metal Work

    All of the above publications were created under the oversightof experienced custom sheet metal contractors so; ultimately, theinformation comes directly from contractors with decades ofin−the−field experience.

    This Guide should not be considered as a substitute for theabove publications, they provide many obligatory details andalternate constructions. Of course, many of the details are left tothe judgment of the custom sheet metal roofing contractor.
