Keeping your roof in top shape is one of the most important things that you can do. Whether you live in an old home or a new one, you should keep an eye on it so that you can identify any damage or issues before they escalate.Make sure to check for wasps, as these are common problems on flat roofs. If you find a nest, make sure that it is not in your way. If you do happen to encounter one, you can always use tar paper to patch the area.
