It depends. If the leak is simply caused by faulty flashing or a small section of roof that has been damaged, then you will most likely only need to repair the source of the leak. If, however, the entire roofing system has failed as a result of poor installation or subpar materials, then a new roof installation is appropriate and often necessary.
We can advise you on this once we have completed an inspection of your roof and provide you with a complete report.
