14

Exteriors:
List six common problems with caulking, trim and flashings.

- Missing or ineffective caulking

15

Exteriors:
Why is common sense so important with respect to evaluating exterior trim and flashings? Discuss a general strategy for inspecting trim and flashings.

- Because not all trim/flashings cause water build up/damage. One must look at all siding for style and installation (uneven, etc) and identify and worrisome points.
- For example, horizontal trim/flashings that are sitting proud can cause water build up. A bead of caulking that forms a sloped shoulder helps to drain water off and protect the joint.
