"roof" over numbers

I'm writing a musicology paper and need some roman/schenkerian analysis tools. Notice the image, the "roof" over the numbers? How to produce this?

You get such a “roof” with \hat:

$\sharp\hat{4}$

There's also \widehat for – well – wider objects:

$\widehat{11}$

Both are mathaccents and therefore need to be used in math mode.

    One probably should define a semantic macro here but since I don't know the meaning of the hat in said musical context I didn't post an example... – cgnieder Nov 28 '14 at 16:09
