How to Fasten Sheet Metal to Wood How to Fasten Sheet Metal to Wood

Fastening sheet metal to wood is required with certain construction projects around the home, such as creating a flashing for a roof. The flashing, which is used to prevent water from entering a seam or joint, is typically made with sheet metal and attached to the studs or the wood in the roof. Understanding how the materials are used together will give you a sense of how best to attach sheet metal to wood so that it is able to perform as expected.

Drill Holes Before Attaching Sheet Metal

Before attaching a piece of sheet metal to a piece of lumber or plywood, you should pre-drill any holes needed for the fasteners. Fasteners include nails and screws that are used to affix the sheet metal to the piece of wood.

Drilling holes through a thin sheet of sheet metal, such as that used for a roof’s flashing, does not require a lot of effort and will make attaching the sheet metal easier.

Use Roofing Nails

Sheet metal can best be attached with roofing nails. These nails are specially designed to go through sheet metal and into wood and provide a seal that is hard for water to penetrate. Water penetration would defeat the purpose of attaching the sheet metal to the wood in the first place. Of the types of fasteners that you may use, roofing nails offer the best fit.

You should practice on scrap pieces to develop a comfort with attaching sheet metal to wood. This practice will serve you well in those projects that you need to accomplish using these different materials.
