I have noticed that there is no commentary of either the Rosh or the Rif on the Fifth Perek of Succah. Is there a reason for this or is it just random?
Thank you.

The Rif and Rosh only comment on Gemaras that have practical connotations today (when there is no Beis ha'Mikdash). Therefore they have no commentaries on Seder Kodshim, or on Perakim that deal with the service in the Beis ha'Mikdash, such as this one (and such as Perakim 6-9 of Pesachim, etc.).
The Chafetz Chayim wrote an ersatz "Rif" on these Perakim, which he called Likutei Halachos.
