Completion Date: May & June 2011

“In what may be the most significant hailstorm in Oklahoma City history, we lost the roofs over six metal buildings. But three other structures with TOPCOAT® product on them came through almost unscathed.”

Charles Musgrave, Musgrave Properties

Building Overview 

  • On May 16, 2010, one of the worst hailstorms in Oklahoma history cut a path of destruction several miles wide through Oklahoma City. The Associated Press reports that the storm dropped “hail the size of softballs, leaving 5" hail drifts in its wake. The hail came in at a 45-degree angle and tore away the north face of every building in the area, chewing through roofing and siding.”
  • Three TOPCOAT® roofs totaling almost 15,000 square feet held up to one of the most severe hailstorms in Oklahoma history. The elastomeric properties of the TOPCOAT® product prevented damage to the coated metal roof systems, leaving only imprints in the coating but no dents or damage to the metal roof.
  • The three TOPCOAT® roofs that survived the hailstorm were applied in 2004 with 18 dry mils of field coating and 78 mils on seams and flashings. 

The Challenge

  • Approximately 30,000 square feet of EPDM single-ply roofing “were completely punched through with holes from the hailstorm,” said Musgrave.
  • About 50,000 square feet of gravel-covered built-up roofing (BUR) were nearing the end of their 30-year service lives when the storm hit. Insurance adjusters felt these older BURs needed to be replaced because wind scour had swept away the roofs’ protective gravel surfacing. 

Solution

  • Gravel-covered, multi-ply asphalt roofing is a proven roofing solution in areas of Oklahoma prone to nickel-and-dime-size hailstorms, according to Musgrave.
  • The three TOPCOAT® roofs were easily repaired after power-washing and applying several mils of new coating.
  • TOPCOAT® membrane is a proven performer that stood up to a severe Oklahoma City hailstorm and is available with warranties of up to 20 years.
  • Properly designed and installed, EnergyGuard™ Tapered Polyiso Insulation Systems offer high thermal efficiency and virtually eliminate ponding water.
