Roofs play a key role in protecting building occupants and interiors from outside weather conditions, primarily moisture. The roof, insulation and ventilation must all work together to keep the building free of moisture. Roofs also provide protection from the sun. In fact, if designed correctly, roof overhangs can protect the building's exterior walls from moisture and sun. The concerns regarding moisture, standing water, durability and appearance are different, reflected in the choices of roofing materials.
Here are the goals when inspecting the roofing system:
- to report on the type of roof covering material;
- to report on the visible condition of the roof covering;
- to inspect and report on the visible flashings;
- to evaluate the roof drainage and gutter system;
- to report any overhanging tree branches that may have an adverse effect on the roof covering;
- to report on the chimney system;
- to identify any obvious deficiencies of roof penetrations and through-the-roof components and their flashings;
- to report on any visible deficiencies in the underlying structure (for example, swayback ridge beams);
- to report the methods used to inspect the roof (for example, from the eaves with a ladder, or from ground with binoculars);
- to inspect and report on roofing trim, such as rake boards, soffits and fascia boards; and
- to report on any visible roofing problems that can be inspected from accessible areas of the attic, such as signs of sheathing problems, evidence of moisture intrusion, or damaged structural components, such as split rafters and damaged trusses.
