Subject: Re: Roof vent could prevent wind damage by CentralCoaster on 2008/5/1 16:27:24 I don't see how generating a vacuum inside those domes does anything to hold the roof down. It just sucks the dome against the roof structure. If you stuck a bunch of toilet plungers against the roof, it won't help hold the roof down. Now if they could do something to let the pressure balance out above and below the roof, like vents, it would be less likely to tear off. Oh wait, they already do that. I guess there thing could help keep the roofing surface on on a commercial building with a sealed roof surface and a sealed roof deck (doesn't exist), but it won't keep the roof structure from getting blown off. I didn't know commercial roofs had problems in high wind, there's not much to come loose. Many of them are using built-up roofs that are sprayed on, more durable and energy efficient. |
