Materials are referenced by Constructions, Constructions are referenced by surface objects such as BuildingSurface:Detailed, Wall:Detailed etc. Walk your way up, ensure the Material you tweak is referenced in at least one construction that itself is referenced by at least one surface.
You can also check your eplusout.err, it may have mentions about unused constructions in your file (you may need to add Output:Diagnostics, DisplayUnusedObjects;, see I/O ref here)
