It's important to understand that roof rods only offer protection from direct hits on the house. Not only do you need the correct number AND size of rods per sq ft: the system must be properly grounded as per your soil conditions. This system does not protect you from lightning surges thru the electric, phone and cable lines. You will need additional systems to protect your home from ground surges and near hits. I strongly suggest you check with your insurance company for their recommendations before you sign any contracts...
