WHY REPLACE WHEN YOU CAN RESTORE?
Roof restoration typically costs half as much as total replacement.

  • Coatings are 100% tax deductible the year of installation
  • Fast, easy, non-disruptive installation
  • Energy-efficient cool roof technology
  • Seamless membrane cures & prevents rust
  • Backed with long-term, sustainable warranties

AWS a Coatings Industry Leader

An established leader in the coatings industry, American WeatherStar (AWS) is a full line supplier of high quality, energy efficient, watertight roof coating systems for commercial and industrial buildings. These remarkable systems can be used to stop leaks, cool a building’s interior, or simply for preventive maintenance and flat roof repair. American WeatherStar offers long term warranties that cover just about every type of roof substrate against leaks on both materials and/or systems. Our coating products line includes acrylics, butyls, silicones, both single component and plural component fast set urethanes, and all the primers and flashing grade products required to ensure complete waterproofing.


COATING VOCABULARY

ELASTOMERIC COATING
Coating that forms a monolithic, fully adhered, fluid applied roofing membrane. It has elastic properties that allows it to stretch and return to their original shape.

VISCOSITY

  • Spray Grade Thickness low enough to allow the material to be pump-able. Base and top coat.
  • Mastic A broader term used to describe the items listed below. Mastic is typically used in
    waterproofing so it is thicker than a spray grade.
  • Brush-Grade Slightly thicker material that is tough to spray. However, this material is often times
    extruded through a pump. Material should still be self-leveling. Our most common use
    is for fasteners on a metal roof. Other uses include seams and penetrations.
  • Butter-Grade A whipped material – thicker than brush grade. This material should not sag and is not
    self-leveling. Used primarily for penetrations, vertical and horizontal seams.
  • Flashing Grade The thickest of the mastics. Used for seams and penetrations.

ROOF MOISTURE DETECTION

  • Core Cut To cut into a roof down to the deck. Pull the approximately 2” wide sample of the roof to survey to determine if the area is wet. A core cut is only as good as exactly where it is taken.
  • Tramex Moisture Meter The Tramex MEP Moisture Encounter Plus is a non-destructive overall building inspection moisture meter which has applications for numerous industries. It has many unique features that make moisture measurement and evaluation fast, precise and versatile. Like a core cut the handheld moisture meter is only as accurate for areas where you place the meter. Typically a hand held meter only measures 1” deep.
  • Infrared Scan Typically performed by a professional with training. An infrared scan uses specialized equipment at dusk to determine if moisture is in the roof system. The basic premise is that water cools at a slower rate than dry material. As the sun light dissipates the camera will show the difference in temperature. The roof should be marked along with a detail report submitted.

DATA SHEET TERMINOLOGY

  • Dry Time Amount of time it takes for the coating to be dry to the touch or walk on.
  • Cure Time The amount of time it takes for solvent to leave the film and for most of the chemical
    reaction to take place (two component or moisture cure systems).
  • Elongation The % a coating can be stretched before it breaks.
  • Tensile Strength The amount of pressure a coating can withstand before it breaks.
  • Solids by Volume The percent of solid material remaining after the coating has completely dried. Measured by applying coating on a surface; measuring while wet then measuring again 24-48 hours later.
  • Solids by Weight Similar test based on weighing the coating when wet and again when dry
  • Permeance A measurement of how much WATER VAPOR can travel through the coating over a set
    period of time.
  • Water Absorption The percentage of WATER that is absorbed into a coating when it is submersed in water for a set period of time.
  • Reflectivity The % of the total sun’s rays a coating will reflect.
  • Emissivity The % of the sun’s rays that were not reflected, that are released by the coating.
  • Flash Point The temperature that a coating or vapor will catch fire when an open flame is introduced
    at a specific distance.
  • VOC’s Volatile Organic Compounds—measured in grams per liter. This figure represents the #
    of grams of organic compound that are contained within each liter of coating. Volatile =
    will evaporate. Organic Compound = large class of gaseous, liquid, whose molecules
    contain carbon: example – mineral spirits.

FILM THICKNESS

  • Dry Film Thickness (DFT) measured in Mils. The thickness of a coating material or system once cured.
  • Comparator A magnification device that allow us to accurately measure dry mil thickness from
    samples cut from a roof.
  • Wet Mil Gauge A hand held device used to measure the thickness of coating on the roof while still wet.

OTHER CRITICAL TERMS

  • Fluid Applied System A complete roof coating system made of specific products for priming, waterproofing, base coating, and top coating. The system is what is warranted by the mfg.
  • Details Schematic drawings of specific transition or waterproof areas with step by step instructions of best practices for waterproofing using a specific manufactures products.
  • Mil 1 mil = .001 of 1 inch.
  • Field Adhesion Test A test performed on a specific roof surface to ensure coating adhesion. See test procedures.
  • Batch Retain Typically a pint of material from every batch blended in a coatings plant. These retains are held a minimum of six months.
  • Waste Factor The extra coating that needs to be figured into a project to account for over-spray or material left in the drum or pail.
  • Stretch Factor The percentage of extra square feet of metal that must be accounted for on a ribbed metal roof when figuring coating material.
