I always like black and red in a logo, The "marketing psychology of color" identifies black as stability and strength, and red as being able to draw attention. If you believe any of that, and I do, it certainly works in your favor.
I like the simplicity of it as well.
If I had to make a criticism I'd want the top of "Robertson" to be even with the top of the roof and the bottom of "Roof Cleaning" even with the bottom of the house. I'm not too crazy about the house, maybe it could use some bling? Also I'd leave the "Non-Pressure" out of it.
Is that legally the name of your company? Looks like your moving along!!!
I emailed Keith at kbkgraphx@runbox.com for help with my logo, been meaning to do it lately and this reminded me. He's designed for a few guys on here and certainly has a knack for our industry.
