Repairing tar and gravel roofs can lead to a very complex process should there be significant damage or improper installation. This is the process for fixing tar and gravel roofs:
- Find the spot where the leaking is happening, look for areas where gravel is missing and tar is exposed.
- Clear off gravel in a 100 sq.ft area around this low spot and dry completely.
- Cut out any blisters that may be found. Allow to dry. Cracks and blisters are leak points in the system
- Apply tar underneath the cut areas and fold cut into the tar. Ensure the coat is applied to the entire area and extends past the repair area.
- Apply asphalt-saturated fabric to repaired area over the tar, then another layer of tar to the repair area and beyond to the old roof.
- Push stones over repair area.
This repair for tar and gravel is simply a temporary fix until the entire roof can be replaced. Repairing tar and gravel roofs can be very complex as the system is designed in a way that leaking can follow a sideways pattern making it difficult to find the initial leak in the system.
