One of the most critical parts of the [[Sukkah]] is the [[S'chach]], the natural covering of the [[walls of the Sukkah]].
One of the most critical parts of the [[Sukkah]] is the [[S'chach]], the natural covering of the [[walls of the Sukkah]].<ref>Rashi (Sukkah 2a s.v. delo) writes that the word Sukkah is derived from the word Schach which is the primary part of the Sukkah.</ref>


==Basic requirements of S'chach==
==Basic Requirements of S'chach==
# There's three conditions regarding the [[S'chach]] (covering) of the [[Sukkah]]. It must be made from a material that grows from the ground, is unattached from the ground, and is impervious to impurity (see further for examples). <ref>S"A 629:1, [[Sukkah]] 12a based on Devarim 16:13, Yalkut Yosef Moadim page 123, Chazon Ovadia [[Sukkot]] page 14. </ref>
# There's three conditions regarding the [[S'chach]] (covering) of the [[Sukkah]]. It must be made from a material that grows from the ground, is detached from the ground, and is impervious to impurity (see further for examples). <ref>Rambam (Sukkah 5:1), S"A 629:1, [[Sukkah]] 12a based on Devarim 16:13, Yalkut Yosef Moadim page 123, Chazon Ovadia [[Sukkot]] page 14. </ref>
# Material that is grown from the ground but is completely changed from its original form is unfit. <ref>Rambam (Sukkah 5:4)</ref> For example, paper and cardboard are unfit for Schach. <ref>Yalkut Yosef 629:14</ref>
===Grow from the Ground===
# Metal, dirt, and animal hides are unfit for [[S'chach]] as they do not grow from the ground. <ref>S"A and Rama 629:1, Yalkut Yosef Moadim page 123, Chazon Ovadia [[Sukkot]] page 14 </ref>
# Metal, dirt, and animal hides are unfit for [[S'chach]] as they do not grow from the ground. <ref>S"A and Rama 629:1, Yalkut Yosef Moadim page 123, Chazon Ovadia [[Sukkot]] page 14 </ref>
===Attached to the Ground===
# Branches attached to a tree which is still attached to the ground is not fit for [[schach]]. Therefore, if one put that over his [[sukkah]], and then decided to detach them from the tree one must shake each branch by lifting and placing back down, otherwise it is not kosher as this is a problem of taaseh vilo min ha'asuy. <ref> Yalkut Yosef Moadim page 123, Chazon Ovadia [[Sukkot]] page 33. </ref>

===Impervious to Impurity===
# One may not use food as Schach since it is susceptible to impurity.<ref>Rambam (Sukkah 5:3)</ref>
# One may use spices which are only meant to be smelled or flowers which are only meant as decoration as [[Schach]] since they are impervious to impurity.<ref>Rav Ovadyah Yosef in Chazon Ovadia ([[Sukkot]], p. 23)</ref>
===Bamboo Mats===
# Bamboo mats made for [[S'chach]] which are 3x2 meters according to most poskim are fit for [[S'chach]]. <ref>Chazon Ovadyah ([[Sukkot]] pg 25-6). Halichot Shlomo (pg 128) and [http://www.yutorah.org/lectures/lecture.cfm/764662/Rabbi_Hershel_Schachter/%D7%A2%D7%A0%D7%99%D7%99%D7%A0%D7%99_%D7%99%D7%95%D7%94%D7%9B'%D7%A4_%D7%95%D7%A1%D7%95%D7%9B%D7%95%D7%AA Rav Hershel Schachter] (min 78-79:30) are also lenient unlike Rav Elyashiv (quoted by Sh"t Shevet HaLevi 6:74) who is strict. </ref>
==Thickness of the Schach==
# The [[S'chach]] should be made so that there is a majority of shade and minority of sunlight that's let through the [[S'chach]]. If there's an equal amount of shade and sun in the actual [[S'chach]] it's unfit but if there's an equal amount of shade to light that shines on the floor of the [[Sukkah]] it's fit. <ref>S"A 631:1 and 4 </ref>

# The [[S'chach]] should be thin enough that one can see the large stars through the [[S'chach]]. <ref>S"A 631:3 </ref>
# If one made the [[S'chach]] very thick so that one can't see the stars nonetheless it's fit. However, if it's so thick that when it rains a lot water won't come in then it's unfit unless there's no way to remove some [[S'chach]] in which case one may rely on the lenient opinions. <ref>S"A 631:3, Mishna Brurah 631:6 </ref>

# If one made the [[S'chach]] very thin so that there's patches of empty space it's fit only if (1) there's no area of empty space larger than 3 [[Tefachim]] and (2) there is a majority of shade and minority of sunlight (counting the entire area of the [[S'chach]]). Even if it's an acceptable [[Sukkah]], nonetheless, if there's a patch of 7x7 7 [[Tefachim]] which has more sunlight than shade one may not sit in that area. <ref>S"A 631:2 and 4 rules that if altogether there's a majority of shade and minority of sunlight and there's no open space of 3 [[Tefachim]] it's fit. Rama 631:2 adds that some are strict if there's an area of 7x7 [[Tefachim]] which has more sunlight than shade. The Aruch HaShulchan 631:5 and Mishna Brurah 631:4 writes that in such an area one may not sit. Mishna Brurah adds that if there's such a patch that breaks up one of the walls so that there's only 2 walls left then it puts the whole [[sukkah]] into question. </ref>

==Schach Held Up by Unfit Items==
# One must ensure that one's [[Sukkah]] is under the open sky and not beneath a tree, roof of a house, or a porch. (For details about after the fact see the footnote.) <ref> Rama 626:1 writes that in all cases one should avoid building one's [[sukkah]] under a tree or roof. Mishna Brurah 626:1 and Aruch HaShulchan 626:1 explain that it's best to build the [[Sukkah]] under the open sky. This is also the opinion of Chazon Ovadyah ([[Sukkot]] pg 11) and Yalkut Yosef Moadim page 125. However, after the fact, Aruch HaShulchan 626:1 writes if it's built under a roofed area it's unfit, but if it's built under a tree there is a discussion about when it is fit. S"A 626:1 (according to Beiur Halacha s.v. VeYesh, Mishna Brurah 626:10 and 11) rules that a [[sukkah]] under branches of a tree is fit only if it fits three requirements (See S"A with Mishna Brurah 626:10 and 11). (1) Among the branches of the tree there is majority of sun and minority shade (2) the there is less than four [[Tefachim]] of tree branches over the [[schach]], and (3) there is a majority of shade from the kosher [[schach]] and a minority of shade even without the tree branches (and even so the sachach under the tree branches itself is unfit but the rest of the [[sukkah]] is fit). </ref>

# One shouldn't use [[schach]] with a foul odor or whose leaves are falling off because there is a worry that the person may come to leave his [[sukkah]] because of the smell or the leaves falling on him. <ref> Shulchan Aruch 629:14 </ref>
# One shouldn't use [[schach]] with a foul odor or whose leaves are falling off because there is a worry that the person may come to leave his [[sukkah]] because of the smell or the leaves falling on him. <ref> Rambam (Sukkah 5:1), Shulchan Aruch 629:14 </ref> After the fact, it is valid. <ref>Rambam (Sukkah 5:1)</ref>
# Although it is permitted for any person to place the [[schach]] <ref> Shulchan Aruch 635:1 </ref>, it is preferable to be stringent and have an adult Jewish male place it on the [[sukkah]]. <ref> Kaf Hachayim 635:8 </ref>
