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.
