I have built an outside earthen oven, as in the double chamber oven, And Im contemplating various ways of protecting it from the weather. One idea I liked was to simply cover it rather than build a roof which takes up quite some space. However, The main argument against doubts is that's it simply isn't pretty to look at a plastic sheet all year round rather than the beautiful oven you built.
I would be prepared to use proper roof tiles but I don't want to build a structure that can support them. That would mean a lot of foundation work and equally take up a lot of space. I am looking for a solution that is lighter, Like sheet metal . I don't like tar paper.
Can anybody imagine a type of roofing, possibly even involving some natural materials (as in unprocessed). Obviously it needs to be water repelling, Strong enough to withstand strong rain, if possible not too susceptible to Wind and not easily flammable, However the roof Will be quite high and further precautionary steps would be possible to make something heat resistant. The only obvious types of natural roofing I can think of is Thatching, Which obviously is not to suitable over an oven.
