LLFA Tape Used to Repair Leak Due to Ice Dam on Roof

“We don’t just sell this product, we use it too!”

In March of 2015, we had a serious flooding in the walls in our heritage home. During the winter, snow and ice
had built up in the valleys of the roof, causing water and condensation to gather in the walls until our

living room ceiling came crashing down. This process is known as “ice damming”.

ICE DAMMING: How it Works:

It required a major renovation from our insurance company contractors, who had to tear down the rotted drywall. When the walls were down and the pipes were exposed, we found this vertical sewer pipe approximately 60-years old. This cast pipe had developed pin hole leaks which had been sealed by an ineffective material that had leaked out of the holes it was intended to plug (*pic A).  If they had gotten worse, it would’ve required us to open the wall again. So the prevent future issues, we wrapped the pipe with LLFA Tape (*Pic B).

The benefit to using LLFA Tape is, once its applied, it fuses with itself, thus forming a bond or “rubber sheath” on the leak or connection. As its primary function is sealing through compression, there is no issue with adhesion and compatibility. It doesn’t lose its tension over time, even in harsh environments.
