  • Does Roof & Deck Concentrate protect the roof against mold and mildew after washing, and if so, how long?

    Special ingredients in Roof & Deck help prevent regrowth for one to two years, depending on the climate situation. For maximum protection against mold and mildew regrowth a sealant is recommended.

  • After I have cleaned wood with Roof & Deck Concentrate should I apply a protectant?

    Yes! Yes! Wood naturally "grays" over time due to weathering and exposure to U.V. rays. Unprotected wood, even though clean will still "gray out" rapidly without a protectant.

  • When cleaning cement how much pressure should I use?

    Cement, due to its porous nature, is very difficult to clean. The higher the psi, the better. Note that our products will brighten and remove oils, grease and mold and mildew stains but will not remove rust stains. For rust removal, we recommend our rust and stain remover called Premier Surface Prep Rust and Stain Remover to remove the toughest rust stains easily.

  • When using Roof & Deck Concentrate to clean vinyl siding, aluminum siding or painted surfaces at thirty to one should I allow it to dry?

    No. On these surfaces only, you should not allow Roof & Deck to dry. A dwell time of five minutes is sufficient. Also, at this dilution it may be run through the downstream injector for application. A small test spot should be performed prior to cleaning painted surfaces and higher dilutions may be adjusted accordingly.

  • How long should I let Roof & Deck Concentrate soak before rinsing?

    Twenty minutes. However, shaded areas on roofs may require a little extra dwell time.

  • Will Roof & Deck Concentrate kill plants, grass or shrubs?

    No. However, you do not want to spray directly on the plants.

  • What if I have applied Roof & Deck Concentrate to a roof and get rained out?

    As long as Roof & Deck had proper soak time prior to rain, you will see that a good rain will completely clean the roof. Sometimes a quick rinse after the rain has past is all it takes.

  • Does a roof or deck need to be dry before applying Roof & Deck Concentrate?

  • Can I use the injector on my pressure washer to apply Roof & Deck Concentrate?

    Injectors by design dilute product at a minimum of one part chemical to fifteen parts water. This dilution is too high to do the job properly. If you have an injector system that dilutes product as recommended, try it out but be sure proper dilution rate is followed. Using an injector for diluting Roof & Deck when dilutions are above one part to thirty parts water will work fine.

  • What is the best way to apply Roof & Deck Concentrate?

    A plastic pump-up type garden sprayer is a good way to apply CleanRoof but may be rather slow if you do this in a professional capacity. For quicker application, a pre-spray system is recommended. For more information on custom pre-spray systems, please contact us.

  • What kind of dilution can I expect when using Roof & Deck Concentrate?

    The recommended dilution rate on the bottle is one part Roof & Deck to six parts water; however, some of our clients are finding that they can dilute up to 20:1. This dilution rate should be considered a starting point. If rinsing with low water pressure, this dilution rate may be needed. If using with good water pressure, dilution rates may be adjusted. Rates as high as one part Roof & Deck to eight parts water are currently being used by many professional contractors. When cleaning painted or vinyl starting dilution rates should start at one part Roof & Deck to twentyfive parts water.

  • What pressure is recommended when using Roof & Deck Concentrate?

    On asphalt shingles a minimum of 75 psi and a maximum of 150 psi should be used. On wood, 500 psi maximum is all you need to rinse.

  • Should high pressure be used on asphalt shingles and wood?

    High pressure can be a very destructive force when used on asphalt shingles and wood. On shingles, excessive pressure removes the granules that protect the shingle from U.V. radiation. When the granules are even partly removed, the roof begins to deteriorate at an accelerated rate, depending on the amount of granules removed. Because of this, roof life can be reduced dramatically. On wood, high pressure can splinter and remove large amounts of the soft inner wood pulp, leaving the wood with a rough and scarred look.

  • Why shouldn't I use chlorine bleach on asphalt shingles and wood?

    Chlorine as a cleaning compound is harmful to the environment including shrubs, grass and other plant life. Chlorine requires multi-applications as well as tarping shrubs and the use of high pressure to rinse. Chlorine breaks down the fibers in wood and also leaves behind a residue that prevents proper bonding of protectants and sealants shortening the life of the protectant.
