Field notes
The example is set to a south-facing Seattle deck in full sun with no sealant, and the timeline reports color loss, surface checking, mildew or rot, and the first likely failure points. The site groups 25 cities by the modeled stress on untreated cedar and gives estimated life ranges, while noting that these are model estimates. Its stated next additions include siding, roofing, and exterior paint.
