How to repair the flashing on a leaky flat roof.
Follow these steps:
1. Remove all old caulking and tar that was used to seal the flashing
2. Use an angle grinder with a hard-wire steel cone brush to remove about five inches of paint on the brick or cement wall above the metal flashing
3. Wipe the metal flashing thoroughly with lacquer thinners to remove any residue of silicone from the metal
4. Use masking tape to seal about three inches on the wall above the metal and also 2 inches below the grove on the metal. (this is for making it look clean when done)
5. Apply one coat of Super Silicone Seal covering the entire area between the two masking tapes.
6. While wet, embed the Polyester Fleece into the Super Silicone Seal
7. Apply a coat of Super Silicone Seal to cover the entire fleece
8. Wait 30 min and then remove the masking tape.
