A flat roof gives your structure a sleek, modern profile, but it comes with its own share of special considerations. Although most “flat” roofs actually feature a slight pitch, they still collect more rain, snow and debris than traditional roofs, making them a safety liability. Caring for your flat roof in winter requires more prevention – best performed in autumn – than it does wintertime labor. Even in warm regions, you can take measures to bolster your roof against winter wind and rain.
