  • Step One - Solidifying The Base Sheet

    Step one
    Step one

    Building code stipulates that flat roofs have a base sheet to separate roofing materials from the underlying plywood. This way, if the building is subjected to outside forces such as heavy winds and earthquakes and the plywood moves, there's a good chance only the base sheet will be torn, not the roofing materials. Unfortunately, over time there is enough movement caused by outside forces to create cracks, tears, and buckling in the roofing materials themselves.

    In reconditioning, we repair the roofing materials and use them as our base sheet. This has advantages over tearing the roof off and installing a new base sheet. For starters, the roof has been contoured into the shape of the underlying structure and is less prone to developing new failures. In addition, because we completely repair the roof and make it stronger we end up with a solid, substantive base sheet for our reconditioning materials.

  • Step Two - Reinforcing Weak Areas

    Step two
    Step two

    Flat roofs have a variety of penetrations and breaks to include skylights, pipes, A/C units, parapet walls, adjoining walls, etc. The underlying decking in all these areas shifts and moves causing numerous failures in the roofing materials. Other than shoring up the sub-structure itself the only way to stop these failures is to reinforce every penetration with high quality reinforcement materials. Each penetration has its own unique problems so to do it cost-effectively we need to use the right materials for the right job, and in the right way.

    Drains and scuppers are extremely vulnerable and require super strong, super adhesive, super flexible materials. In addition, for inaccessible areas under the equipment on sleepers we jack the equipment up and doubly reinforce these areas with strong, mildly flexible materials.

    Areas that pond more than 1" of water are filled with Tuff-Light to lessen the weight load and prevent future damage to the underlying beams and rafters.

    Most importantly, we bond all reinforcement materials to the adjoining building surfaces with super strong, super adhesive, super flexible flashing materials.

  • Step Three - The First Layer Of Waterproofing Materials

    Step three

    A waterproofing layer of Rubberized Colloidal Bitumen is then sprayed directly on top of the solidified roof. Our proprietary Restructuring Membrane is imbedded by hand into the Rubberized Colloidal Bitumen. The end result is an excellent waterproofing barrier as colloidal bitumen is the only roofing material in the industry that's impervious to standing water. See the 'Additional Information' section for details regarding this outstanding waterproofing material.

  • Step Four - The Second Layer Of Waterproofing Materials

    Step four

    A monolithic layer of Rubberized Colloidal Bitumen is then sprayed directly over the Restructuring Membrane. To prevent alligatoring of this heavy concentration of Rubberized Colloidal Bitumen chopped fiberglass is incorporated into it. The fiberglass not only prevents the Rubberized Colloidal Bitumen from alligatoring, its tensile strength also improves the durability and sturdiness of the membrane making it 100% impermeable.

  • Step Five - Protecting The Colloidal Bitumen With A Pure Aluminum Topcoat

    Step five

    The Rubberized Colloidal Bitumen is protected from UV radiation by the application of a Silver-White or Kool-White topcoat. Silver-White is a state-of-the-art mixture of pure aluminum and colloidal bitumen, where the aluminum coalesces to the top forming a protective shield of pure aluminum. Both the Silver-White and Energy Star Kool-White topcoats keep the facility cooler during hot summer days.
