Loose light litter such as paper, leaves and twigs raised from ground level in spirals. Secured tents and marquees seriously disturbed; a few exposed tiles/slates on roofs dislodged.

One example of pan roof systems can be found in this document from Structall Building Systems Archived 2016-03-04 at the Wayback Machine .
But he said the wind speed gauge used was 250 metres lower and in an area that was more protected from gales. Ridge tiles from a house landed on this car just three weeks old [Anand Patel]
Closing all interior doors helps disperse the pressure throughout your home, reducing the effect that all of that force can have on your roof — basically the one thing that separates you from ...
