About 3 months I started a website (www.guyetteroofing.com) for my roofing business in Montgomery, Alabama. The site is still a work in progress, however, because the competition doesn't really market via internet it was fairly easy to rank on Google Maps. Within 1 month the business was letter "A" in Google Maps. About 3 three weeks ago my ranking was dropped considerably, not showing up at all in letters A through G. The business is still indexed in Google Maps, but only represented by a small red dot. My website is still ranking pretty high for "roofers in Montgomery", but my position on Google Maps has all but disappeared. I have no idea what I've done to be rank so low on Google Maps but still have a solid position on regular Google Search. I've checked my citations and my NAPs, there are a few inconsistencies but nothing major.  How can I rank so far below my competition if I have twice as many citations, an actual website, and a Google Plus page?

I started this website about 2 months ago, www.guyetteroofing.com. I know it still needs a lot of work, but I can't find any information on it on the site explorer tool.
