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.
Deteriorated and corroding post-to-base metal hardware brackets at deck systems should be replaced for safety reasons as they no longer serve their intended purpose. This was discovered at a recent home inspection on Orcas Island in the San Juan Islands. When metal brackets begin to rust and corrode, painting with an exterior metal paint will help prolong serviceable life. Once they’re deteriorated, however, they’re clearly compromised and require replacement.
When I pulled back an interior plant box, I discovered a completely deteriorated metal structural support column base at a recent home inspection in Bellingham. This metal support column happened to be in a moist environment, interior swimming pool room, and was definitely compromised. I recommended further evaluation and repair by a qualified contractor.
Rusting describes the process of the corrosion of iron and its alloy, steel. InterNACHI inspectors, homeowners and commercial property owners should understand how rust forms and how to prevent it. Rust is more than a cosmetic issue; it can lead to serious structural deterioration.
