Welcome to our blog!
We want you to be an informed homebuyer, and each blog post is a question that we have answered for our friends and customers over the years. Hope they help you make a good choice for your next home.

    The inspector is required to include a photograph of the metal connector observed as part of the submission of the Wind Mitigation Form, which is formally known as “OIR-B1-1802.”

   To learn more about how to make your home more hurricane resistant, click below to download a pdf of the booklet “Make Mitigation Happen,” by the Florida Division of Emergency Management.


While we hope you find this series of articles about home inspection helpful, they should not be considered an alternative to an actual home inspection by a local inspector. Also, construction standards vary in different parts of the country and it is possible that important issues related to your area may not be covered here.

The best tie-down discount is for “Double Wraps,” which is either one Single Wrap on each side of the truss/rafter or a single metal connector, like the one shown below, that is secured with a minimum of three nails on each side; however, we rarely see double wraps.


Next is “Single Wraps,” a strap that goes over the top of the truss/rafter and down the other  side, secured with a minimum of two nails in front and one more on the back of the wrap. A Single Wrap that is not nailed properly gets dropped back to Clips level if it has three nails on the front side.


The photo below shows a strap with only two nails securing it to the truss, so it will be dropped back to the toes nails level discount.

The first level that receives a worthwhile discount is “Clips,” and a photo of one is shown at the top of this page, and also an illustration below.
