How to Look

at a House


A blog with answers
to your questions about
HOME INSPECTION
and HOME MAINTENANCE

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.

    Photographs taken in the attic that document the roof attachment are required. The inspector finds a “shiner” (nail that is not correctly aligned and sticking of the side of the truss/rafter), and takes a photo of it with a tape measure next to it to show the length. An 8d nail will extend past the sheathing approximately two inches, and a 6d nail—which is the next lower discount level—protrudes about one-and-a-half inches. Next, the inspector finds the spacing of the nails using an electronic device and marking each nail location on the side of two truss/rafter locations, and photographing the markings, once again with a tape against the area to show spacing.

    Since the inspector is required to list the weakest connection, any part of the roof has not been re-nailed to the new standard means it does not get the highest discount. The “B” discount is given when 8d nails are at six-inch nail spacing only at the edge of roof sheathing panels and 12-inch nail spacing in the field. Last, the “A” category is for 6d nails or staples.

    Each of the three categories can be used for an alternative fastener type, such as adhesives or screws, that matches the uplift withdrawal rating, in psf (pounds per square foot), of that category.



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.
