Most shingle manufacturers recommend at least four nails per shingle and six in high wind areas such as Florida and Oklahoma. That answers the question about the minimum number of nails and we’re sure you realize that the minimum will be good enough for fast buck roofing companies, plus they’ll use the cheapest roofing nail they can find.
Answering the question about how many nails we use per shingle is a bit different and we’ll go light on the technical details yet not so light that we end up being vague. We use 4-6 nails per shingle, depending on the area and steepness of the roof. Let us explain a bit more.
First, our nails are 1¼ inch hot dipped galvanized, ring shanked for extra “bite” versus a smooth shank that is less secure. These nails are installed using an air driven nail gun to assure the shingles are fully secured. Each nail actually goes through two shingles; the one that is getting nailed and the one underneath it. That is why every shingle is actually getting 12 nails.
The value of how many nails we use, and the type of nails, has less meaning without converting it to how much wind your roof will withstand. Our installation method will endure hurricane velocity winds exceeding 130 MPH. That’s beyond even the worst gusts you should ever have to worry about in Southeast Michigan.
