2. What is Softwash? when is it used
Softwash is a process which uses low
pressure. Most commercial pressure washers
use
2000-4000 psi, Kleen and Shine uses < 100 psi
to apply chemicals for cleaning, and 800 - 1000
psi for rinsing.
High Pressure (Pressure Washing) should never be used to clean house siding
3. What are those Black Streaks on roof?
Unsightly black stains or streaks on
asphalt shingles are caused by a hardy
type of algae called Gloeocapsa Magma.
The algae feeds on the crushed limestone
that is used in asphalt shingles. Rain
spreads the algae down the roof causing
the black streaks. These streaks are not
only unsightly but cause the shingles to fail
prematurely by not allowing the shingles to
reflect heat properly.
4. 50% Of Roofs Are Replaced Due To The Way They Look.
This is not because of their functionality. Half of the roofs ever replaced in the
Midwest didn't need replaced, only cleaned. Just as mold and mildew can grow
on your vinyl siding, wind blown algae can land and grow on your roof.
Replacing your roof because of this algae is like replacing your siding instead of
having it cleaned; it just doesn't make sense.
Some roofing contractors don't know what these black streaks are, saying it's
the asphalt showing through the shingles or that it's water stains. Some
contractors may know it's algae but tell you it can't be cleaned without
damaging the shingles. In either case, they may tell you that the roof needs
replaced. This is not true if your shingles are still in good shape. The algae can
be killed and removed properly without damaging the shingles using a low
pressure chemical application (recommended by shingle manufacturers).
5. Roof Cleaning Is Recommended By Shingle
Manufacturers.
Companies like Owens Corning and GAF, and also the
Asphalt Roofing Manufacturers Association recommend a
low pressure chemical application using certain cleaners to
restore shingles suffering from roof algae, followed by a low
pressure rinse. We use the cleaners and methods
recommended by these companies, for a safe and damage
free roof cleaning. If your shingles are still in good shape
but have roof algae on them, having your roof cleansed will
allow you to get the full life out of your shingles, saving you
thousands of dollars.
10. House Wash
House wash uses the same softwash
process and roof cleaning. We use
different chemical mixes based on
the type material used for home siding.
