Another happy client secured his house against heavy winter snowfalls. The problem was that trying to address the trouble with snow avalanches our customer was advised by another company to have snow guards installed on his metal shingles roof. This project failed because this tiny stand-alone snow holders hardly stop any snow at all. You can see this round objects on the pictures above.
The solid tubular snow guards from Roof Experts work differently: they can withstand any load, while the sliding down enormous snow mass will be gradually sliced into small safe chunks.
