Leaking roofs are one of industry's most persistent and costly problems. The loss of insulating properties, structural deterioration and damage to interiors caused by these leaks cost owners of flat, built-up roofs billions of dollars every year. Much of this expense is wasted because the entire roof is removed when only a portion of it actually needs replacing.
