The Seiden was originally roofed with shingles; this was changed to grey or black ceramic tiles in the 1670s or 1680s, and then to the iconic red terracotta tiles sometime later. Though there was some debate as to how to tile the roof when restoring the castle in the 1980s-90s, planners ultimately decided to use red terracotta tiles, as the castle's history of red tiles had been longer and as red tiles had come to be so widely regarded as an iconic feature of Okinawan architecture. There has also been some debate as to whether certain portions of the facade or pillars were painted black or red, and historical sources are unclear as to this point. Though restoration efforts in the 1980s-90s originally began with the intention of painting these sections black, reports from repair efforts in the 1920s-30s revealed that earlier layers of red had been found when stripping down the pillars (in order to repaint them) at that time.<ref name=shuriqa/>

From the time of its reconstruction in the early 1990s until its destruction in an Oct 2019 fire, the Seiden was the largest wooden building in Okinawa prefecture. Sadly, regulations did not require a structure of its size and character to have a built-in sprinkler system; this, combined with the inaccessibility of the site and the early morning outbreak of the fire, contributed to the ultimate outcome of the structure burning to the ground before firefighters could get the fire under control.<ref name=nhkfire/>
