Spray foam is a very specialized packing material, often required for use in shipping valuable fragile items. Engineered packaging principles are designed to protect sculptures, vases, large fossils, lamp bases, busts, computers, furniture, chandeliers and other objects of unusual shape. By virtue of the liquid foam expanding by up to 30-60 times the volume of its liquid state, it efficiently protects almost any size, form and weight. https://www.youtube.com/watch?feature=youtu.be&v=ggLAUsiuI_o
It is also capable of reflecting more than 90% of the sun’s rays, which further increases its protective nature. In addition, it offers protection from moisture while also being designed to be sturdy regardless of the weather and climate it is exposed in. Such is the main reason why many view it as capable of forming a thick blanket of protection, which is similar to rubber. https://m.youtube.com/embed/ggLAUsiuI_o
It should be noted that your RV roof will be exposed to rain, freezing, and thawing that will eventually cause cracks. By using a high-quality sealant, it is possible for you to seal all cracks in the roof permanently. The result is cool camping within your RVs. The use of the sealant will also prevent you from facing expensive repairs in the future.
I don't know if it's common or uncommon, but installing a layer of rigid foam above your roof sheathing in order to interrupt thermal bridging is always a good idea, and is preferable in all respects to a roof assembly without any rigid foam above the sheathing. If you decide to install rigid foam above the roof sheathing, you shouldn't use closed-cell spray foam under the sheathing; either use open-cell spray foam (which is vapor-permeable) or a fluffy insulation like cellulose, mineral wool, or fiberglass (any of which will allow the roof sheathing to dry to the interior).

Stop making the same repairs using less reliable products that are not EPDM based, are not UV and ozone resistant, and do not have flexibility built into the material (causing them to crack). EPDM rubber will expand and contract with any surface as seasons change, and will not crack as a result of temperature changes. Other products will begin to bubble and crack in less than two years.
