Roof Color
Attributes
Green and brown
Such a roof is typically
composed of growing
grass and plants atop the
main roof which is
adequately protected with
a membrane to allow for
irrigation.
TPO is manufactured using
ethylene propylene
rubber, a material that has
excellent flexibility as well
as durability regardless of
the weather type.
This material works
perfectly regardless of
whether the weather is
hot, cold or wet.
Clay tiles are most suitable
for warmer climates since
they can shatter easily
under the heavy hail
conditions in colder areas.
Clay can be disposed of
safely as it is
biodegradable.
Metallic materials have
low heat capacities, so
they heat up quickly in
warm weather and cool
off quickly when it’s cold.
These roofing materials
also have colors that
reflect away the sun’s
rays.
