Materials

A roof system can be designed with varying qualities of roof components. High quality components add value to roof performance, longevity, aesthetics, and other areas building owners should consider.

• 1

  Polyisocyanurate (Polyiso) vs. Expanded Polystyrene (EPS)

  Polyiso provides a higher R-value per inch than any commercially available insulation product. Better insulation products will reduce the cost to heat and cool a building.

• 2

  Coverboard vs. No Coverboard

  A coverboard like DensDeck or SecureRock over insulation provides a hard surface that results in better roof performance against hail and an excellent thermal barrier for exceptional fire, moisture, and wind uplift resistance properties.

• 3

  Fleeceback Membrane vs. Standard Membrane

  Fleeceback membranes offer another level of toughness and durability over standard TPO and EPDM membranes. Industry leading resistance to hail damage and superior wind uplift resistance are reasons why owners should consider upgrading the membrane to Fleeceback. Also, Fleeceback warranties can include coverage for up to 36 hours of work annually to repair accidental punctures.

  Metal Edge or Coping vs. Term Bar

  Sheet metal termination on the edge of the roof is a vital component for wind uplift resistance and aesthetics of the building. Metal edge or coping cap performs better in high wind conditions than term bar…and makes the building look nicer as well.
