You have two basic options: You can choose a complete replacement of the roof system, involving a tear-off of your existing roof system, or re-cover the existing roof system, involving only the installation of a new roof system. If you’ve already had one re-cover installed on your original roof system, check with a professional roofing contractor. In many instances, building code requirements allow no more than one roof system re-cover before a complete replacement is necessary.
A leaking roof is a bad thing. However, it doesn’t necessarily warrant a complete roof replacement. How much repair and work needs to be done on your roof depends on the level of damage caused by leaking. Talking to a professional is the best way to know whether only minor repair OR a full roof replacement is necessary.
