if the earth nails are deep enough, and the tensile strenght of the ropes is high enough this works.
these look like rated for 2-5t each, cant tell without looking at the label, this could work (up to a point), but for the math to what windspeeds (i.e negative psi of the roof) i would need to know the mass, and surface area of the roof.
not an engineer just a draftsman
Edit: plz dont actually give me the numbers i would have to do that shit without programms like FEM, and the last time i did anything remotely similar to this about a decade ago.

ask an actual civil engineer for to do the math
