Roof Cleaning Northern Virginia

[Roof Cleaning Virginia]

Here's one of the roof cleanings we did last week while the weather was warm. Can't wait for Spring!

What actually causes the black streaks on the roof?

[Roof Cleaning Virginia]

Technically it's a form of cyanobacteria although most folks in the industry, including the shingle manufacturers call it a blue/green algae (Gloeocapsa magma). Here's a better description: http://en.wikipedia.org/wiki/Gloeocapsa_magma

You couldn't walk that roof with a set of Cougar Paws?

[Roof Cleaning Virginia]

Sure, or even without cougar paws on that one. But the bucket truck is my work truck - it goes to all jobs with me. So I market it and use it.

looks good Ted, I like your truck, wish I had one

Hey Don, do you use cougar paws?

Gotcha. My neighbor has that problem on his house but his is the only one and was asking me what it was and what caused it but I had no clue. Thanks for the link.

You're quite welcome. Here are some pics from another winter job we just did yesterday, this time in Woodbridge VA. There's a before and immediately after pic, plus an aerial pic. With the sun being so low in the sky this time of year, we do a final inspection from a higher elevation so we can see it clearly. The glare is fairly bad otherwise.
