Q) Do I need a new roof ?
A) Maybe not , click here to be directed to a site that may help you decide what is best for you , or you may click here to
look directly at the algae stain solution.
Q) What products do you use to remove roof stains?
A) Our products are proprietary and only available to authorized, trained, and certified dealers. They are biodegradable,
environmentally friendly, and nontoxic. Material Safety Data Sheets (MSDS) are available to our customers for all of the
products that we use. You should never allow anyone to use cleaning agents around your home without asking for the
product MSDS.
Q) Will the process harm my plantings around my home?
A)No. The products that we use are extremely gentle and will not harm any vegetation or surfaces around your home.
Q) Do you use high pressure power washing on the roof?
A) NEVER! High pressure power washing can be very damaging to the shingles. Plus, it’s simply not an effective way to
remove algae stains from roofs. All of our roof cleaning equipment is specially calibrated at a very low pressure to ensure a
gentle safe rinsing away of all the algae and stains that are loosened by our products.
Q)How long will the algae related stains stay off my roof once removed by Prokleen Roof cleaning?
A) When we finish cleaning your roof, it will be as clean as a new roof. Since it’s impossible to tell how long it will take for a
new roof to get algae stains, the same holds true for a roof cleaned by Prokleen Roof Cleaning. However, we will give you a
written warranty against any roof staining for a period of one year. Most roofing shingle manufacturers won’t give you any
warranty against algae on a new roof installation.
Q)Is there anything I can do to keep the stains off my roof for the life of the shingles?
A) Yes. We offer an annual roof maintenance program for all of our customers. Once your roof has been cleaned by us, at
your request we will return once a year for a fraction of the cost of the initial cleaning to apply a special spray on, leave on
treatment to those previously cleaned areas. Every consecutive year that you participate in the program extends your
warranty for an additional year. In other words, we guarantee to keep the stains off with each preventative treatment for the
natural life of the shingles.
Q) What about the do-it-yourself products?
A) These products can cause many problems. First of all, just about all of them say “toxic” or “poisonous” right on the bottle.
They are largely ineffective in the long term, as well as the short term as far as roof stain removal goes. Also, whenever
homeowners climb up on their roof, they put themselves at risk of slipping and falling. Roof cleaning is serious business
and it’s always best to rely on the professionals.
Q) Do zinc or copper strips work?
A) If algae is already growing on the roof, zinc and/or copper strips will do nothing to remove it. Although both zinc and
copper have properties that may curtail the growth of algae, you’d have to place so many strips on your roof for them to be
even marginally effective that your roof would not look very appealing. Many homeowners who have tried the strips end up
peeling them off and tossing them away within a few years.
Q) Can’t I just put bleach on my shingles?
A) Be very, very careful here. Many homeowners and contractors alike have tried to use bleach or pool chlorine to remove
the dark roof staining caused by algae. The results can be disastrous if you do not know how to properly handle this harsh
chemical. We use a special mixture of chemicals to insure the safe removal of the harmful parasites growing on your roof
Q) What if I just leave the algae stains on the roof?
A) Algae is a living, growing organism and as such, will continue to grow. Left untreated, in time it can cover your entire
roof. A roof covered in algae absorbs heat and results in a superheated attic, raising your cooling costs. In addition, since
algae feeds off the organic material in your shingles, left untreated, your roof will require costly, premature replacement.
Why allow that to happened when you can have your roof professionally cleaned and restored to its original, natural color
for a fraction of roof replacement costs?
Q) Why should I choose Prokleen Roof Cleaning over another local contractor?
A) Several leading shingle manufacturers employ us and our process for their warranty roof cleaning because our process
is gentle and effective. Many local contractors use damaging high pressure to clean roofs, often causing more harm than
good. Often, they do not carry insurance or have Material Safety Data Sheets available for the chemicals that they use.
Many of these companies start one day and are gone the next. Do your homework before hiring anyone to do work around
your home.
