While professionals can expect
to complete roof cleaning jobs in a timely fashion, a do-it-yourselfer
may take a little longer. However, by using our pressure washers and following directions, you can achieve professional results and
have a brand new looking roof, all by yourself, within a reasonable
time frame, without killing your plants and grass! It's safe to
say that it’s impossible to control all variables, but you
can fight them and win with preventative maintenance services or
long term protection. Our #513 Mach 1 Degreaser is ideal for most roof cleaning applications.
Black staining is caused by the growth of algae and fungus spores
that land on your roof, (Staining is not caused by pollution, soot
or jet exhaust). These spores need three things to grow: heat, moisture
and some kind of nutrient. The nutrient comes from dirt and the
shingle itself, primarily the limestone filler used in manufacturing
the granules. Shingle roofs are manufactured with different degrees
of quality. Pricing is one way to tell the quality of a roof and
the manufacturer warranty is another. Most roofs applied by builders
and roofing contractors are in the low to medium quality range.
Higher quality roofs are generally found on expensive custom homes
and where the owner has taken a special interest in the quality
of the roof.
Clay tile roofs are fragile and caution should be taken when walking
on these roofs. Wood shingle roofs will require the least amount
of pressure at about 1000 PSI or less. When pressure washing any
roof use caution around flashing. Never pressure wash at an angle
that will allow water to flow up the roof and under the shingles.
Bleach should not be used on shingle or wood roofs as it will cause
damage. You never want to try to pressure wash from a ladder. The
pressure from the wand can knock you off balance.
To protect your roof from early replacement, annual pressure washing
is recommended. You will want use between 1000-1800PSI depending
on your roof material. Metal roofs are becoming more popular because
of price and the length of time it lasts, a higher pressure may
be used on these type roofs. You should always contact the roofing
material manufacturer to find out recommended pressures for their
product. You may want to try an extension
wand for those hard to reach places.
A note of caution: Cleaning your roof by yourself can be hazardous.
Roofs over a 7/12 pitch are not walkable, even for trained professionals.
A roof is not going to clean itself nor is it only going to take
five minutes. Cleaning a roof is a project that is going to take
some time and effort and a few trips up and down the ladder. For those who want the best tool for the job, and the safest way to clean your roof, you'll want our Mosmatic DR 520 Roof Cleaner.
