Strong gusts of wind can really do a number on your roof. Here’s a look at the different causes of wind damage from your expert local roof storm repair contractor.
Wind is uplift is one of the most destructive forces. It’s the vacuum created by wind into which materials are then lifted. It is usually created by either loss of laminar flow (as explained below) or increased wind speed. They both reduce the air pressure immediately above the roof-covering material.
Air flowing close to a surface is in a state called laminar flow, where it tries to keep in contact with the surface. When that surface bends or curves, the air flow can’t keep its contact, separating from the surface. This is where it loses laminar flow and creates uplift. Anything that can move is then lifted up into that vacuum if the vacuum is strong enough. Manufacturers these days design residential and commercial roofing to have fewer bends or curves for wind to keep its laminar flow.
Increased Wind Speed
Naturally, the sheer brute force of wind is the most obvious culprit of roofing damage. Wind speed on the roof increases by two and a half times its approaching speed, lowering air pressure above the roof. The reduced air pressure on the roof surface increases the amount of uplift. Imagine your roof being constantly pounded by harsh winds, and you’ll get the drift.
