The design, the materials, the maintenance. Let’s face it, most of us don’t really know what’s up there protecting us. It’s battered by the wind, the rain, snow, and the sun and it’s supposed to take it all without any complaints or leaks. In this episode, Duo Dickinson, architect and author of “A Home Called New England” tells us what the perfect roof has to deal with, while Anne Cope, Chief Engineer of the Insurance Institute for Business and Home Safety shares how roofs are tested. You’ll also hear tips from This Old House’s Charlie Silva and Jeff Sweenor on how to keep roofs in tip-top shape and what to do when you need a new one.
