Frequently Asked Questions

Why should I choose a Roof Shampoo™ ?

The Roof Shampoo™ roof cleaning process is proven, safe, and effective. Many local contractors use damaging chlorine bleach and high pressure to clean roofs, often causing more harm than good. Many of these companies start one day and are gone the next. Do your homework before hiring anyone to do work around your home. When it comes to roof cleaning, it’s wise to choose a company that is using a proven method – choose a Roof Shampoo™ dealer.

What if I just leave the algae stains on the roof?

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?

What products do you use to remove roof stains?

The Roof Shampoo™ products are proprietary and only available to authorized, trained, and certified dealers. They are biodegradable and environmentally friendly.

Will the process harm my plantings around my home?

No. Our products will not harm any vegetation or surfaces around your home.

Do you use high pressure power washing on the roof?

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 safe washing away of all the algae and stains that are released by the Roof Shampoo™ products.

How long will the algae related stains stay off my roof once removed using the Roof Shampoo™ system?

When Roof Shampoo™ technicians 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 using the Roof Shampoo™ system. However, many Roof Shampoo dealers™ give their customers 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.

Is there anything I can do to keep the stains off my roof for the life of the shingles?

Yes. our Roof Shampoo™ dealers offer an annual roof maintenance program for their customers. Once your roof has been cleaned by by one of our dealers, at your request, they will return once a year for a fraction of the cost of the initial cleaning to apply a special spray on, leave on Roof Shampoo™ stain prevention 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, the guarantee to keep the stains off your roof with each preventative treatment extends for the natural life of the shingles as long as you continue to receive the annual, preventative treatments.

What about the do-it-yourself products?

These products can cause many problems. Many of them are toxic to the vegetation surrounding your home. Plus, 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.

Do zinc strips work?

If algae is already growing on the roof, zinc strips will do nothing to remove it.

Can’t I just put bleach on my shingles?

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. First of all bleach and pool chlorine are dangerous chemicals that can damage vegetation and dry out your shingles. Often, any results that the homeowner sees are just temporary and the staining is back within a few short months because the bleach merely addresses the surface algae and not the root system underneath the granules. In addition, bleach around your home could void your termite treatment as chlorine neutralizes many of these chemicals.
