Unless you are in a zone colder than 6 or 7, most roses are planted with the graft above ground. Perhaps you can offer your roses some protection or caging to help them weather these terrific storms.

Where are you at? You only need to bury the bud union in cold zones. Otherwise the graft should be right at the surface of the soil. Planting the bud union deep will not necessarily prevent canes from breaking off. If it's that windy you should stake and tie tall canes to help support them.

Sorry, I believe I live in zone 7a

If temperatures around +5 or zero can occur, the graft should be protected. Raising the bed is easier than replanting or providing annual mounding. You can do this while the roses are leafed out if you want to.

Easy enough to check. Just go to the website below and enter your Zip code.

In warmer zones, the main reason to be planting the bud union at soil level is to stabilize the bush. A budded rose that is whipping around in the wind - which it will do if the union is SIGNIFICANTLY above the ground - is not good. Besides potentially breaking off canes, it will open up the soil to winter cold air getting to the roots.

Our budded roses are planted with the union at about soil level, and we went through Sandy and the subsequent noreaster without losing a cane.

Replanting correctly or raising the soil level are always available options, but before I opted for that major effort I would try staking the bushes and see how that works.

U could always try a surround of cobblers and fill in with mulch. I have a few like this ( double d and Joseph's coat) and they have done quite well for several years. This will give you a few inches and it looks quite nice.
It also delineates the drip line..
