Adam: Jews are showing how they are good at thinking ahead and in this case it is making the parapet to prevent people from falling off of their hooves.
Jackson: If you have an animal you must take very very good care of it and have a watchful eye for what it does like washing your hands before you to touch them and by making an enclosure and keeping the enclosure nice and clean. That will keep the animal nice and health
(א) מצות מעקה - להסיר המכשולים והנגפים מכל משכנותינו, ועל זה נאמר (דברים כב ח) ועשית מעקה לגגך. והענין הוא שנבנה קיר סביב הגגות וסביב הבורות והשיחין ודומיהן, כדי שלא תכשל בריה לפל בהם או מהם, ובכלל מצוה זו, לבנות ולתקן כל כתל וכל גדר שיהיה קרוב לבוא תקלה ממנו, וזה שהזכיר הכתוב לגגך דבר הכתוב בהווה ולשון ספרי ועשית מעקה מצות עשה (עי' ספהמ''צ להרמב''ם עשה קפד).
(1) The commandment of a parapet: To remove stumbling blocks and obstacles from our dwelling places, and about this is it stated (Deuteronomy 22:8), "and you shall make a parapet for your roof." And the matter is that we should build a wall around the roofs and around the pits and the ditches and that which is similar to them, so that no creature should stumble to fall in them or from them. And included in this commandment is to build and fix every wall and fence from which it is likely that there come a mishap from it. And that which verse mentioned "for your roof," is [because] the verse spoke in the present (using the most common example). And the language of Sifrei is "'And you shall make a parapet' is a positive commandment" (see Sefer HaMitzvot LaRambam, Mitzvot Ase 184).
Micah: Having someone at your house and on your roof and you have a parapet on your roof does not mean you are fully protected from responsibility for the person falling. You and the parapet have to protect a clumsy person from falling off the roof.
From 70 Faces of Torah, KiTeitzei, by Tyler Dratch
The Torah enjoins those who are constructing a new dwelling to install guardrails on the roof to ensure safety. Each of us has an obligation to partner with God to prevent the loss of life. The Talmud teaches that the one who then falls from was pre-destined to do so since the days of creation (BT Shabbat 32a). I take this to mean that there will always be people teetering on the edge whom we will not be able to protect from danger. The important question is whether we have helped to put the guardrails in place to minimize the risk.
Miya: All Jews should have a liability to build a railing around their roof to insure that everyone has safety when they go on their roof so that no Jew or non-Jew can fall off and get hurt and that we have to protect the people we have and protect the life that come to our house
