What's the Black Stuff on my Roof?

Often, homeowners call with a specific question -- what is that black stuff on my roof?

The answer is simple -- it's probably roof algae.

As Roof Repair Blog points out, the stuff is actually called Gleocapsa Magma, and it can not only detract from your roof aesthetically, but it can also cause damage and drive up your cooling costs in the summer (the black color absorbs the sun's heat instead of reflecting it).

Any single one of these is a problem for a homeowner -- but if all three strike, it's a major problem. If you see some of this "black stuff" on  your roof, call a professional as soon as you can!
