Here are 4 things you should never use to make Chimney leak Repairs
- Caulking – whether it is latex, silicone, or urethane caulking, it will always fail.
- Tar – any tar out of a can will fail – it dries and cracks
- Tapes – It is very tempting to get a roll of tape. Tape does not work on uneven surfaces; it will leak from the onset
- Spray Sealant out of a can – that is by far the worst so-called sealant

9 Steps on Chimney Leak Repairs
The Crown of the Chimney
The top part of a Chimney
In most chimney cases, a cement slab is on top of a chimney. This cement slab will crack and also separate from the bricks where it was poured. Water can get through these cracks, and leaks will appear inside your house. Use Turbo Poly Seal to make repairs. Watch the video to see how to seal the chimney crown.
The Flashing on a Chimney
The bottom part connecting to the roof
Flashing is the metal at the bottom of the chimney that connects the chimney to the roof. In most cases, this flashing is slotted into the chimney, and caulking is used to seal it. This caulking will dry out and shrink, and the seal will break, causing leaks. Watch the video on how to seal the flashing with Turbo Poly Seal.
Field Stone Chimneys
Chimneys that have natural stone
When a chimney is built or decorated with natural field stones, it has a 90% chance of leaking. It is very hard to detect leaks and seal them from leaking. You are much better off rebuilding the chimney using bricks or concrete. You can use Alex Plus clear caulking to seal the fieldstone’s cracks.
- Use an angle grinder with a wire brush to clean all existing caulking, paint, and tar from the flashing or chimney crown.
- Remove any loose cement grout where necessary.
- Use masking tape to tape off the area where you seal the chimney.
- Make sure to allow at least 2″ of space on either side of the crack where you will apply the sealant.
- Use Turbo Poly Seal to brush the 1st coat on the surface, covering 2″ on each side of the crack.
- Cut a polyester fleece and apply it over the 1st coat of sealant.
- Brush the 2nd coat of Turbo Poly Seal to cover the Polyester fleece.
- Remove the masking tape after 5 minutes of curing.
- Apply Silver Coat protection after 24 hours of curing.

A 5-minute Repair Metal Roof Leak with Super Silicone Seal, the surface must be free from dirt and moist. The seams on a metal roof must be screwed down tight to avoid much flexing.
The advantage of using Super Silicone Seal is that Ultraviolet rays do not affect it. The silicone will not degrade in heat or icy conditions. The disadvantage is that paint will not adhere to it.
Here are 5 things you should never do when repairing a Metal Roof
- Never use caulking to repair seams or seal screws.
- Never use Tar to fix seams – tar will dry out and crack
- Never use the same size screws when replacing or tightening them
- Never step on the risers of the metal – they crease and start leaking
- Never coat an entire surface to try and repair leaks. The coating is only necessary when there is rust, but not to fix leaks
Silicone will adhere to metal, glass, plexiglass, wood, and asphalt.
To Repair Metal Roof Leaks, follow these steps:
- Prepare the surface where you want to patch.
- Use a flat bar, hammer claw, or trowel to remove big chunks of dried tar or other roofing materials.
- Use an angle grinder with a wire brush to remove existing silicone caulk, asphalt, and paint.
- Take a rag and saturate it with Lacquer Thinners to clean asphalt residue and silicone from the surface.
- If necessary, replace the existing screws with slightly larger ones. Use pane head screws where possible for a low profile.
- Use a paintbrush and paint the 1st coat of Super Silicone Seal over the seam. Ensure you cover at least 2″ on each side of the seam.
- Embed the Polyester Fleece into the silicone, squeezing out all the air.
- Apply a 2nd coat of Super Silicone Seal over the fleece, ensuring it is completely covered.
It can rain 1 hour after applying the Super Silicone Seal. It takes about 24 hours to cure completely.
It is important to remove old tar, caulking, and paint before making any repairs. Turbo Poly Seal will adhere to asphalt and paint, but the paint could peel off rendering the repair non-effect.
See this video of how the tar and paint peeled off to understand why you should remove it before attempting any repairs.
Most people are afraid to remove material from previous repairs. They are afraid that they might disturb something and cause more problems. This is furthest from the truth. It is always better to start with a clean surface.
Use an electric grinder with a wire brush to remove old rust, paint, and caulking. It is important to have the metal surface clean from any debris as well as silicone residue. To make sure there is no silicone residue left by the wire brush, you can use Lacquer Thinners with a rag to wipe the surface clean.
It is super important to use eye protection when cleaning the metal surface
Once the surface is clean, then you can make the necessary repairs with Turbo Poly Seal.
