How it Works
The EraserSpacer™ is a breakthrough in the roofing industry that permanently rids rooftops of unsightly black streaks. Say “goodbye” to the days of expensive power washing solutions with harmful chemicals that could weaken a roof or void its warranty.
Step one: we remove the exposed row of shingles below the rooftop’s ridgeline and install a long copper strip.
Step two: we install the EraserSpacer™ panels, which conceal the copper base sheet, securing it with screws and a special sealant.
Step three: we place shingles over the EraserSpacer™ panels. Over time, streaks disappear and never return.
Leaving your roof looking brand-new and extending its lifespan up to a decade.
Why do black streaks happen to good roofs?
It starts with the shingle.
Today, roofing contractors use limestone as a filler for modern asphalt shingles – a natural food source for bacteria and algae growth. Over time, rain falls and interacts with the shingles, and microbial parasites called “Gloecapsa” (blue-green algae) form as they feed off the limestone. Black streaks form as a result.
This not only affects the curb-appeal of your home, but it also weakens your shingles and impacts the longevity of your roof over time.
How does the EraserSpacer™ fix the problem?
The EraserSpacer™ disrupts this growth of algae as rain water interacts with the copper plate technology. As rain falls onto your home, small copper ions detach from the panel and run down the slope of your roof.
When these ions encounter algae spores, they kill them on contact and wash them off your roof for good; leaving your rooftop clean without expensive chemical cleaners.
