Your site is very poorly optimized. You would benefit a lot by implementing basic SEO best practices. A good place to start is here: http://www.seomoz.org/beginners-guide-to-seo
Regarding Bing/Yahoo, Bing has a 10 year agreement to control Yahoo's search results so they are basically the same company from a search result perspective. They have different ownership then Google and operate differently. If you have an outstanding site, then your results may be aligned but otherwise there is often differences.
What keyword are you trying to rank for? A best practice is to focus a single keyword per page. Your home page title is: Roof Installation, Roofing Contractor, Siding Contractor Chicago, IL. Apparently you are trying to rank for multiple words which will not yield the best results.
Another sign of your keyword focus is your H1 tag which is missing on your home page.
When I search Google for "All American Exterior Solutions" you rank #1. If you want to rank for "roof installation" there is a lot of SEO work to perform. Your home page only uses the term a single time in content and it is not in the first sentence so it does not appear to be the focus of the page. You also have another page of your site which is better optimized for the term: http://www.aaexs.com/residential/roofing
Also, your footer is incredibly spammy.
Google desires to return relevant, quality pages in their search results. You may be a great company but your web pages need to improve in order to rank in Google for the terms related to your business.
