"What we do is simple, effective and very efficient". As Roy Walsh, Vice President of Young Builders Roofing describes it, "In addition to new construction installations, we also overlay and replace existing roof systems, including single ply roof membranes, conventional B.U.R. and rolled roofing assemblies with Young Builders Roofing's DURAGARD Roofing System."
Roy Walsh VP Young Builders

Application Procedure

The Process is as follows:

  1. CLEARING & CLEANING THE SUBSTRATE:
    The surface of the roof is thoroughly cleaned of all loose dirt and debris. Blisters and/or buckled areas are cut and nailed. Wet or deteriorated roofing must be completely removed. The surface is primed as needed.

  2. PRE-APPLICATION:
    Remove and reset roof-mounted mechanical equipment. Replace and/or cover all skylights and install new metal flashings at new lumber skylight curbs.

  3. FOAM APPLICATION:
    A blanket of insulating 1" minimum polyurethane foam is applied over the entire surface. (No maximum urethane foam thickness).

  4. BASE COAT  APPLICATION:
    The DURAGARD elastomeric base coat is then applied sealing the new urethane foam and providing excellent protection from the sun's damaging ultra violet rays.

  5. FINISH COAT APPLICATION:
    Shasta #9 Limestone Aggregate is then broadcast into the uncured DURAGARD high quality acrylic elastomer topcoat. Available in White, Beige or Tan.

  6. FINAL:
    Final detailing and debris removal from the jobsite. A quality control final inspection takes place to ensure the highest quality workmanship and complete customer satisfaction.

APPLICATION PROCEDURE

DURAGARD UL Class A Industrial Roof System (Polymer Modifed White Cement Traffic Topping)
Application Procedure

  1. Spray-in-Place Insulation Procedure: Urethane foam insulation consists of a two-component sprayable type specifically manufactured for roof insulation.
    1. Apply insulation to all low and/or ponding areas to reduce standing water.
    2. Spray-apply 1", 2.5 - 3lb density urethane foam over all roof areas to waterproof and insulate the roof substrate. Insulation shall be carried up all adjacent vertical surfaces to waterproof all penetrations and roof-to-wall junctures. Additional foam insulation may be applied to taper and enhance drainage and/or to provide greater R-value.
  2. Fluid Applied Waterproofing
    1. Apply DURAGARD acrylic elastomer base coat at the rate of 1-1/2 gal/100sf.
    2. Apply DURAGARD acrylic elastomer second coat at the rate of 1-1/2 gal/100sf.
    3. Apply DURAGARD acrylic elastomer top coat at the rate of 1-1/4 gal/100sf to all vertical surfaces.
    4. Terminate coating application 4" above foam termination.
    5. Apply Shasta #6 roofing granules onto uncured second coat at the rate of 60lbs/100sf.
    6. Apply DURAGARD C-Cure modified cementicious roof coating into embedded aggregate at average of ¼" thickness to provide a 100% foot traffic resistant hard cement shell surface.

DURAGARD 2 Residential Roof System

  1. Spray-in Place Insulation Procedure: Urethane foam insulation consists of a two-component sprayable type specifically manufactured for roof insulation.
    1. Apply insulation to all low and/or ponding areas to reduce standing water.
    2. Spray-apply 1", 2.5 - 3lb. density urethane foam over all roof areas to waterproof and insulate the roof substrate. Insulation shall be carried up all adjacent vertical surfaces to waterproof all penetrations and roof-to-wall junctures. Additional foam insulation may be applied to taper and enhance drainage and/or to provide greater R-value.
  2. Fluid Applied Waterproofing
    1. Apply DURAGARD acrylic elastomer at the rate of 1-1/2 gal/100sf.
    2. Apply DURAGARD acrylic elastomer second coat at the rate of 1-1/2 gal/100sf using a white color.
    3. Embed Shasta aggregate at the rate of 30-35 lbs/100sf onto wet top coat to provide wearing surface.

DURAGARD 3 Commercial Roof System in Phoenix, Arizona
Example ...

This 90,000 square foot building, constructed in the 1960's, suffered from severe ponding and leaking and the current roofing system was experiencing an overall roofing system failure. The roof surface was cluttered with unused and obsolete mechanical equipment. The dilapidated 4" thick multiple roof assembly consisted of the following layers: two ½" layers of perlite insulation, one 5-ply B.U.R. gravel roof, 1" fiberboard and one 4-ply smooth built-up roof with aluminum coating. This roof was in desperate need of Young Builder's DURAGARD 3 Commercial Roof System and this is how we did it...
Phase one required the removal and demolition of all roof-mounted mechanical equipment and electrical/plumbing runs.
There were many areas where rotted and unsafe metal decking had to be removed and replaced.
Next, the old, wet roofing assembly was loaded onto pushcarts and taken to the landfill.
The installation began with the application of primed (black) 5/8" gyp-substrate over the metal structural deck.
A three-man crew using a transit, shoot and mark the deck elevations in preparation for the foam fill application. This reduces ponding conditions and helps maximize a positive water drainage run off.
Low areas are marked in orange "locate" paint and are then sprayed or filled with urethane spray foam.
The entire roof is sprayed with a minimum 1" application of urethane foam fill. Following the foam application, a layer of gray base coat is applied followed by aggregate and DURAGARD Acrylic Top Coat.
This newly installed roof is now free from leaks, ponding and the clutter of unused equipment and machinery.
The result... a beautiful and professionally installed DURAGARD Foam Roofing System complete with a 10-year warranty!

    4. Embed Shasta aggregate at the rate of 30-35 lbs/100sf onto wet top coat to provide wearing surface.

NOTE: These systems possess a high strength-to-weight ratio, weighing approximately 70% less than a comparable asphalt roof. It locks the roof deck together with a monolithic barrier to heat and moisture. It is adaptable to any configuration upon which it is sprayed.
