8 Warning Signs of Roof Damage

Typical roof damage problems are caused by severe weather and can be used in insurance claims, such as a hail damage roof insurance claim. After a hail storm happens, signs of roof damage may not appear till years later when roof leaking occurs. It is important to have a trained specialist inspect your roof if you suspect damage.
