  • FAQs

    FAQs specific to roof cleaning

    What causes the black streaks on my roof?

    They are caused by Gloeocapsa Magma, the blue / green algae that thrives on many asphalt roofs. While those black streaks appear harmless, they can lead to significant, and expensive damage to your roof.

    Is our cleaning process safe for my roof?

    The Asphalt Roof Manufactures Association (ARMA) highly recommends regular cleaning and maintenance of your roof. Dixon’s follows manufacturers' recommendations by applying a special, safe mixture containing bleach and then quickly rinsing the roof thoroughly with a low-pressure garden hose. Never with a power washer. The most important question to ask a contractor is whether they use a power washer to clean your roof. All roofing manufacturers and professional associations recommend that a roof cleaner should not power wash a shingle roof.

    What cleaning products do you use?

    Mostly water with some bleach and a surfactant. All vegetation is sprayed with water both before and after the cleaning to remove any chemicals. In some cases, vegetation may wilt or turn brown, but most plants will rebound in a few days from the treatment.

    What is our appointment cancellation policy?

    We require cancellation at least 2 business days before your scheduled cleaning. Short-cancels are difficult to fill and since we pay our teams even if you cancel, you will be charged a service call fee if we cannot refill your cancelled appointment time.

    How Do I Pay?

    We do not accept payment on the day of service. We will invoice you approximately one day after service. You may pay by check or credit card (phone or online).
