Unless it’s contained in a sink, pipe, or directed with intention and control in confined areas, water is typically the greatest threat to building structures. While issues such as roof leaks, pipe leaks, and crawl space flooding usually get all the headlines, water damage can also appear through more subtle means.
Case-in-point: I recently came across a home during a Sedro-Woolley inspection, where I noticed a vulnerable, uplifted flashing detail. Flashing is a thin layer of waterproof material that prevents water from penetrating areas where it may cause damage (such as the interface of a roof and siding, or a deck and siding).
Bottom line: pay attention to these seemingly small details because they may save you some big money.
