1. The #1 reason for washing your roof is the improved appearance of your home.  A well maintained roof increases the curb appeal and the re-sale value of your home.   Many homeowners opt to spend thousands to replace their roof, when they could have contracted Soft Touch to wash their roof at a fraction of the cost.

2. The next reason is to maintain your roof.  A dirty roof can lead to the premature failure of your roof.  Maintianing your roof will extend the life of the roof, saving you the replacement cost from early failure.  The Asphalt Roofing Manufacturers Association recommends non-pressure washing (see Roofing FAQ's below for the explaination) your roof periodically to extend the life of your shingles. 

3. The lesser known reason for washing your roof is energy conservation.  When mold, algae and mildew cover up the granules on your shingles, they absorb heat rather than reflect it.  This increases the heatload on your home which requires more energy to cool it. 

4. Comfort is another factor.  If your roof is absorbing heat thus raising the house temperature, it makes your home less comfortable.

Roof Washing FAQ's:  

Why should I use non-pressure washing for my roof? - Non-pressure or low-pressure washing will not remove the granules from the shingles or destroy them.  The soaps that are used kill the mold, mildew and algae and then remove them from the roof.  The warranty on your shingles will remain intact as well.  This is unlikely with pressure washing.

What makes the Algae grow on the roof? - The algae is from microscopic spores that transfer via air borne transmission or from birds and other roof climbing animals.  Fiberglass shingles are manufactured with limestone fillers that act as a food source for the unwanted algae. Once it takes hold, it spreads over the roof.

Why not just wash it myself? - You can go to Lowe's or Home Depot and purchase roof washing soap and if you have the equipment, wash your roof.  The soap that you purchase is not commercial grade and is diluted so that non-professionals do not harm themselves.  You may want to check out this US government article.  The detergents that Soft Touch uses have been tested and modified over many years. Also, this is our profession so we have experience with the equipment and ladders.  We are fully insured so that you and your home are protected. So why not give your house a roof shampoo and clean off those ugly black streaks.
