Q. A friend of mine recently tried to sell a home. The buyers’ inspector discovered that no plywood clips had been installed on the roof sheathing. The roof has trusses 24 inches on-center and either 1/2-inch plywood or 7/16-inch OSB sheathing. Does anyone know a quick and easy fix for this?

A.Robert Allison responds: I don’t know of a "quick and easy" fix for this, but here is a method that I have used. Install 2x4 blocking across each joint from rafter to rafter. These blocks can be nailed through the rafter or truss or toe-nailed in place. Apply construction adhesive to the blocks to glue them to the decking. Though tedious, this simple repair works well. However, it is difficult to do on the first row of decking on low-slope roofs and impossible in some places due to framing members, cathedral ceilings, and so forth.
