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.
