I just got some roll-out asphalt roofing for my wood shed. $45 and it covers 200sqft. Maybe some of those you could re-roof cheap?

I`m not sure what your roof is made of currently... aluminum?

How is it leaking 1 spot or all over?

They have some awesome roof-goop to patch holes, add some aluminum or galvanized steel and you can patch holes 1ft or bigger.
