[papercreters] Roofing

I have been putting old tires to use in as many ways as I could think of,
and I have recently thought of a new way that may be of use to people
building with papercrete.

Take one old tire (preferably from a 4x4). Cut around the circumference
of the tire in the soft side wall close to the tread. Use a very sharp,
sturdy knife as I do or a reciprocating saw with the sides ground of the
teeth. Remove the 2 sections of sidewall. (I place these upside down in
the garden and fill them with cement to give a rather interesting stepping
stone). Cut across the tread with an angle grinder fitted with a metal
cutting disc. This will give you a piece of tread the width of the tire
and around 5 feet long, or longer, depending on the size of the tire.
Make heaps of these and fix them to battens on the roof, one facing up,
the next facing down, as do the Chinese when making a roof from terracotta
pipes or split bamboo halves.

I have been using these treads as weatherboards fixed to the studs
horizontally with galvanized tek screws and they last forever. I see no
reason why, when fixed to the roof purlins vertically they will not be as
effective. And the heat they attract could be directed from the ceiling
space with a small fan into the house as required.
