I had the usual assortment of roof questions from persons with flat roofs. I will sum them up with the following suggestions: Clean out the drains and make sure protective screens are in place. You should do this after all wind storms and heavy rains. Patch any cracks and holes. Trim all trees and scrubs that are close to the house. Make sure the down spouts are free of twigs and leaves and small critters that might have nested there during the dry spell.
