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.

Dealing with rusting metal flashing

Rusting metal flashing details can often be painted with a high quality, exterior-rated metal paint to extend serviceable life and prevent further deterioration.  If you see rusting flashing details atop your roof or around your chimney, I highly recommend painting to prevent further damage; replacement of deteriorated flashing details- especially around masonry fireplaces- can be costly.  These pictures show rust presenting at one flashing detail, corrosion- and due for replacement- at another.  This was discovered at a recent home inspection on Camano Island.

VIDEO: Install Chimney Cap / Rusted Flashings!

At a recent home inspection on San Juan Island, I discovered rusting/corroding flashing details at the chimney that should be further evaluated and repaired to help prevent potential leaks to the interior. Also, the installation of chimney caps is advised over open flues to prevent water intrusion which can reduce the life expectancy of masonry fireplaces. Finally, treating and removing organic growth from masonry is advised, together with applying a masonry sealant to properly maintain your exterior masonry elements.
