SPF roofing systems have exceptional sus tainability characteristics. They save energy, are resistant to high winds, protect the sub strate against damage from hail and wind driven missiles, and are renewable. However, when a SPF roof sustains damage from wind driven missiles or hail, how does one deter mine what procedures are required to maintain the roof’s longterm performance? Under which conditions can the roof be renewed? When must it be scarified, recoated, or torn off?
