•What products do you use to remove roof stains?
Our products are proprietary are only available to authorized Roof Shampoo™ dealers. They are biodegradable and  environmentally friendly.

•Will the process harm my plantings around my home?
No. The products that we use are safe and extremely gentle and 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 gentle safe rinsing away of all the algae and stains that are loosened by our product.

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

•Is there anything I can do to keep the stains off my roof for the life of the shingles?
Yes. We offer an annual  preventative treatment for 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. Every consecutive year that you participate in the program extends your warranty for an additional year.

•Can’t I just put bleach on my shingles?
Be very, very careful here.  Many homeowners and contractors alike have tried to use bleach to remove the dark roof staining caused by algae. The results can be disastrous. First of all bleach is a dangerous chemical 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.

•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 and putting you at risk for costly, premature roof replacement.

•Shouldn’t I just get a new roof?
Some homeowners have spent thousands of dollars on a new roof only to see the algae re-appear on the new shingles several years later. Roof algae can re-appear even more quickly if the new shingles are put on top of the algae infested shingles. Algae growth is an event that occurs in nature and it can, and does, grow on new shingles just as well as older ones. The growth process begins when an airborne spore lands on the roof. The algae then takes root and grows when the shingles it lands on are facing north or west or are moist from morning dew or heavy shade. Having your roof professionally cleaned costs a fraction of premature replacement.  In addition, our customers who take advantage of our annual  preventative treatment are guaranteed algae–free shingles for the life of their shingles.
