Hi MrMarqua there are just a couple of files to edit. Better do this in a child theme though. In the js folder, hashone-custom.js file, you need to add the classes of the pages where there’s not the sticky effect.
In the window.scroll function, change the following line from this:
$('.page-template-home-template #hs-masthead, .home.blog #hs-masthead')
to this
$('.page-template-default #hs-masthead, .page-template-home-template #hs-masthead, .home.blog #hs-masthead, .blog #hs-masthead')

Then, do the same on the style.css of the theme, adding
.page-template-default and .blog to the three sections of #masthead starting at line 1152.

   .page-template-default #hs-masthead,
   .blog #hs-masthead,

and

   .page-template-default #hs-masthead.fadeInDown,
   .blog #hs-masthead.fadeInDown,

and

   .page-template-default #hs-masthead.hs-black.fadeInDown,
   .blog #hs-masthead.hs-white.fadeInDown,

In this last block, I changed to hs-black (instead of white) for readability, as the menu’s text is white.

Hope this helps.

P.S. How did I do it? inspected elements and TextWrangler.
