This is the time of year when all that unwanted debris falls on your roof, all that pine straw, leaves, and fallen twigs. then tend to collect behind your chimney, skylights, and in the valleys of your roof cuasing water to back up and could potentially be come a problem.It’s a good idea to have your roof inspected in a few times darning the fall season as well as the spring clean up season. Preventive maintenance could save you $$$$ in the long run. Leaves in valleys can cause water back up in these areas. Pine straw on roof and in gutters can be trouble. Oh my, photo speaks for it self.
