The days have been windy and cold. Some roof coverings have been damaged, or lifted, losing adhesion to form a weatherproof layer. Some roof coverings can be repaired and some have to be replaced. Your insurance company can provide the necessary funds for repair or replacement per your coverage. They can assess your damage; otherwise a qualified roofer can provide a quote and what items need repair and replacement, such as roof vents and bathroom vent flashings/systems etc.
A qualified roofer can also provide a quote on weatherproofing your roof covering, or provide advice on alternatives such as steel roof coverings and the maintenance required.
