Roof Challenge

The Portales Jr. High School‘s existing EPDM roof had many leaks sourced from the failure of seams losing adhesion at the base flashings and field. The block walls were absorbing water which caused the EPDM roof to begin to fail at the seams.

Roofing Materials Used

  • Canyon Coat Sealer by GAF was used at the parapet block walls.
  • In the field, we installed 1 layer of 1/2″ primed densdeck mechanically fastened and a fully adhered 60 MIL white TPO roof system by GAF.

Roofing Solution

  • RoofCARE satisfied the need for a leak-free, maintainable roofing system through the strategic use of a new TPO roof system. Installing a new 60 MIL roof system over the existing EPDM roof.
  • RoofCARE applied a water repellent (Canyon Tone  Clear Wall Coating) product to the interior roof parapets.

Key Commercial Roof Renovation Facts

  • By waterproofing the block walls at Portales Junior High School we eliminated all potential water entry points to the newly installed TPO roof.
  • After the Portales Junior High School TPO installation was completed there have been several heavy rainfalls and no leaks have been reported.
