Roofs are inspected visually and from an area that does not put either the inspector or the roof at risk. Steep, wet, snow or ice covered roofs are not walked on. Slate, tile or asbestos roofs are not walked on.
- The type of roof and the condition of the top layer will be reported and commented upon. Valleys and roof penetrations are prone to leaking. Worn, missing, patched or otherwise defective surfaces will be inspected and reported based upon normal wear and aging.
- Flashings provide a water tight seal at roof penetrations (i.e. plumbing, chimneys, flues), which are prone to leaking and should be reinspected annually.
- Skylights, like flashings, are prone to leaking and should be reinspected annually.
- Chimneys are very susceptible to the elements and usually are not completely visible due to location and height. Spalling of masonry units is a common problem in cold climates. Interior flue linings often are not visible especially if equipped with a cap covering to prevent downdrafts or screening to prevent sparks. Chimney parging conditions should also be inspected and reported.
- Gutters carry rain water off the roof and away from the foundation. Often they become clogged with leaves and other debris, or will develop sags and/or leaks at the joints. Gutters need periodic maintenance and cleaning.
