Patricia, as the use H1's (or H2,H3, etc) don't have much if any impact on SEO, I wouldn't worry about it. Where on the html page that a word shows up has more of in impact on a page's relevance than the heading associated with it. In fact, keywords in the h1 tag negatively correspond to higher rankings.

No harm in using role=”heading” instead of H1 but as far as Chris is saying about adding keywords in heading tag will negatively affect your SEO... I didn’t experience this myself but obviously you cannot simply ignore the SEL research!
