Roof Cleaning

Black streaking, moss, and lichens make their home on your roof shingles, consuming the shingle for food.  They do more than just look nasty and leave streaks on your roof.  In addition to lowering your curb appeal, they are literally eating your roof and destroying it. They’re airborne algae called Gleocapsa Magma that eat the limestone filler in your shingle and multiply until your entire roof is infested. The longer the infestation is left untreated, the more damage is done in your shingles, drastically shortening their lifespan along with reducing cooling efficiency due to the darker color of the algae absorbing more sunlight as heat.

That’s right, your roof is being slowly ingested by these micro-organisms! In order to save you thousands of dollars on roof repair/replacement costs, we recommend a thorough cleaning of your roof every few years (or when you start to notice these black streaks). This practice will prolong the useful life of your roof. We use safe low-pressure cleaning techniques with chemicals to kill the mold spores at the root which prolongs the time in between cleanings to give you the most value for your money.


There are many factors that determine the difficulty of roof cleaning. Steeper pitches, hip sections, single versus double story, dormer roofs, obstructions such as trees and heavy or unusual buildup of organic growth will increase the cost.

Did You Know?

Those black streaks on your roof aren’t dirt – they’re 3-billion-year-old cyanobacteria that were the originators of oxygen in our atmosphere.  For that, we thank them.  What we could do without, though, is the damage they inflict on our roofs.  These cyanobacteria, a type of algae, produce a black pigment that acts as a kind of sunscreen that reduces the reflectivity of your roof and makes it absorb more sunlight, causing the house to heat up and raise your cooling costs.  Moreover, the algae feed off the limestone in your shingle, drastically reducing its lifespan.
