In January 2000 we experienced a severe windstorm with gusts to 120 miles per hour. Our shingle roof was destroyed. It looked as if it had been hit with a giant shotgun blast. In some spots the roof had been ripped away down to the plywood. Our neighbor had a new Interlock roof installed in 1997. The windstorm that had destroyed our roof did not damage his roof in any way; not a single shingle was missing.
Since installation of our Interlock roof, the snow load on the frame of our house has dropped 95%. We have been through 100+ MPH wind storms with zero wind damage. I would highly recommend this roof to anyone!
