Things You'll Need:
- Ladder
- Wire brush
- Coarse sandpaper
- Black roofing cement
- Putty Knife
- Rags
-
Step 1
Use a wire brush to clean the inner surface around the crack or leaking joint. (make sure this is on the inside,so none of the patch is seen from the ground.)
-
Step 2
Use coarse sandpaper to rough up and prep the area Around the crack or leak. ( I would use 100 grit or 80 grit sand paper)
-
Step 3
Use a damp rag to clean up any remaining dust or dirt. (using solvent or mineral spirts instead of water will speed up dry time)
-
Step 4
Use a putty Knife to apply a liberal coating of black roofing cement over the crack or leak. (a sunny dry day will help with the drying time of the cement)
