 Re: Grounding a Tin Roof
Our company has done projects where the lightning protection systems were a part of our contract. We used a specialty subcontractor for the installation of all the lightning protection systems, without exception.
It looks easy enough to install, so long as you would have the correct design. One big concern is the potential to attract lightning - then not have the proper grounding path to deal with it. Having the wrong installation would likely be worse than having none at all.
And yes, they do use stranded aluminum for roof circuits and downleads. It has a weave to it (not a twist, like normal wire). Lightning rods are very sharp on the tip (to start the arc). There's a nuclear-powered lightning rod (covers an extremely large area and one will replace gobs of regular rods). Believe it or not - the first lightning protection subcontractor we used had a foreman named "Rod".................chim |
