My roof is made from metal. The snow slides off easily in the winter, metal
is fireproof, and does not need much maintenace and care. Other folks use
ceramics which last for centuries. Steel is re-used, but the wooden shingled
roof cannot be reused, nor can it last as long as ceramics and steel. The
use of wood in outdoor settings like roof decks et cetera are temporary
whereas the non-biodegradible products are more often not temporary
structures (with exceptions of course). The very best materials are the
safest and most efficient ones which rules out wood except in terms of
temporary aesthetic settings, and economic short term applications.
Western larch is our most rot resistant species. It is the only wood that I
know of that is termite proof. I forgot to mention all the rots and insects
that devour wooden houses. In the tropics a wooden house can be consumed
within 20 years, a concrete or adobe house may stand for 2-3 centuries. But
wood will not in a tropical area unless it is in the desert of Northern Chile.

The essence is thus the internal determination of to be, that which, when we
conceive to be, we are also forced to conceive: its intrinsic
presupposition. In this its truth consists; essence is radical truth.
The essence of the oak is the "reason" through which this process
"seed-tree-fruit" is a process intrinsically "oaking". And this character of
process which is the essence, Hegel will tell us, is something which we see
ourselves forced to conceive in order that there may be becoming; and
"forced to conceive" is precisely a character of thinking.
