Through a roof has too many laws of physics working for it – just too easy for it to happen if the path is available. The term most used in Architectural lingo and with the Building trade(s) is: Yet, that word is typically used to merely describe the flat cladding or finish covering of the roof overhang elements themselves.
Your roof by necessity, will often times extend over the walls of your home. The signs of corrosion and how to prevent condensation forming Everything looks freshly cleaned and painted when done.
