Pressure Washing And Roof Cleaning
Why should I have the exterior of my residence or
Not only is it important to maintain a clean property for
the aesthetic value and much-desired curb appeal, but also
to provide lasting protection against building material
degradation. When mold, mildew, algae and other environmental
pollutants are allowed to remain on the exterior surfaces
of a property they can contribute to premature paint failure
and can also cause permanent staining on concrete, gutters,
and pool decks.
How long can I expect my property to stay clean?
Each and every property is its own unique situation, but
on average, most surfaces will stay clean for about one
year. Roof surfaces can stay clean for up to three years
or longer. There are many determining factors and variables.
Trees for instance, will create shaded and damp areas, creating
an ideal environment for algae and mildew to develop and
thrive in. Unusually dry or damp weather conditions can
also have a direct effect on the length of time that a surface
will stay clean.
What causes those dark stains on my roof?
The dark streaks and stains seen on many roofs are caused
by an algae, scientifically known as gloeocapsa magma. Once
present in an area, the algae can quickly spread by airborne
spores being carried from rooftop to rooftop by wind, birds
and other small animals. All roof types, including asphalt
and fiberglass shingle, cement, ceramic and clay tile as
well as wood shake or metal are susceptible to algae infestation.
Can a roof be cleaned with a pressure washer?
Honestly, yes. Is it a good idea? Absolutely not! Highly
pressurized water can temporarily remove the visible stains,
but the toll it takes on the roofing material can be extremely
costly. Not only does it not destroy all the algae spores,
but it can remove granules from shingled roofs and cause
color-fading on tile roofs. Replacing a roof is expensive,
not to mention the stress and frustration of having to do
so because of a prematurely failing roofing system that’s
been damaged by too much pressure.
Water leaks can also be a major concern. Often these leaks
go undetected for weeks or months, causing even more damage
to the wooden trusses and rafters in the attic areas.The
above-mentioned questions are but a few of the many routinely
