It is highly recommended to consult a professional roofing contractor who can accurately assess the extent of the damage and provide expert advice on the best course of action.

Step 3: Repair or replace damaged shingles or flashing

Once the repair is complete, thoroughly inspect the entire roof valley, paying close attention to the repaired area. Look for any potential issues or signs of incomplete repair. It is essential to ensure the repair has been successful and that the roof valley is in optimal condition.
