Using a pressure washer
on your roof may seem difficult especially because of the strong jets
of water it produces which can damage the roof material or cause you
to fall to the ground. However, there are a couple of techniques that
you could do to clean your roof through pressure washing, without
damaging it as well as endangering you.
The first step is to
choose the right tip for your pressure washer. Although the washers
have manual controls on pressure, tips also help in adding or
reducing the pressure as well as focusing or widening the spray. The
recommended tip for asphalt shingles is 25 degrees. This is strong
enough to wash dirt and algae, but not too strong as to scrape off
asphalt granules.
When washing your roof,
make sure you have both feet firm on a dry patch. Then, with the wand
at your hand, wash a single shingle first before moving onto the next
and check if it has any damage. If it doesn't, then you're good to
move on to washing more shingles at a time. Remember to check the
shingles every now and then, and do not direct the spray upward into
a shingle as it break it and cause leaks.
Pressure washer damage on
your roof will be a big headache, but with careful hands, you can
turn a pressure washer into a magical dirt cleaning wand that washes
away all those gritty and slimy gunk that has stuck to your roof.
