Your roof is important to your house for more than one reason. Yes, it protects your house from weather and other things, but it also has another job. It helps to keep your house square because it ties everything together and gives additional support to make sure that the walls don't twist or anything. Because of how important your roof is to your home, you want to make sure that it stays as an integral part of your building — even if you live in a tornado-prone area. There are things that you can do when building your new home that will help make your house and your roof more tornado-resistant.
These are clips that will help to secure the roof to the walls. The clips are larger than nails or staples, which are generally used to attach a roof to the walls, which gives them more "bite" when it comes to being fastened in. That additional bite and that additional size gives them more strength. They may not withstand an EF5 tornado, as it is hard for a lot of things to stand up to that much wind speed, but the hurricane clips should help to keep the roof attached in lower strength tornados. The nice thing about hurricane clips is that they can also be retrofitted to your house if you are trying to beef up your house's tornado resistance.
There are studies that have shown that the more slopes you have on your roof, the more it is able to resist tornados. Most houses have the traditional roof style of just two slopes, which tornados seem to really like because they will tear that kind of roof off more easily. However, if you added even two more slopes on your roof, it is going to be that much more secure. This isn't necessarily something that you can do on a retrofit, because it's going to require a lot of structural work. But, if you are building a new home, doing a remodel or adding on to your house, then you could add in more slopes. This is also something that could happen easily while you are building your house. You will want to talk to your builder and roofer about making sure that you have those additional slopes.
