Abstract: A mobile home having a membrane-type roof is stabilized by placement of a plurality of tensioned straps extending transversely across the membrane roof and in contact with the roof over a substantial portion of the length of said straps. The straps are anchored to a structural member at the edge of the roof, so that the straps constitute a permanent part of the mobile home. Hence, during transportation of the home along a highway, as well as during wind storms, etc., any upward flexing of the membrane roof is prevented by the tensioned straps which lie adjacent said roof. A suitable strap may be a 1200 pound test braided nylon rope having a diameter of about 1/4 inch. Springs for achieving tension in the rope may be helical springs about 16 inches long and having a diameter of about 1/2 inch, with said springs being made from steel wire having a diameter of about 1/32 inch.
