Metal roofing over an indoor residential living space always requires some sort of underlayment. The underlayment may consist of felt, a synthetic material, or existing roof shingles in good shape, depending on the building code requirements in your location. Metal roof underlayment provides additional water intrusion protection and can have insulating characteristics.

There should be small gaps between your roof and the walls of your home, and other buildings. These small gaps let building materials shift, expand, and contract with weather and other outside forces, and they prevent moisture from wicking down walls from roofing and gutter systems. Without these strategic gaps, your home’s exterior and its finishes can sustain water damage, decay, peel, delaminate, and crack. However, there is a fine line between a smart gap and a problematic gap—all  gaps should be small, intentional, and covered or filled in with foam insulation to prevent pests from using them as access points.

The easiest way to tell if your roof vent boot is leaking is to look in your attic for signs of water damage. You might see visible moisture, water spots, or mold on the roof decking around the roof vent or damaged or soggy insulation below it. If you don’t have access to your attic or aren’t sure if the vent boot is the issue, hire a professional to come inspect your roof and figure out the underlying issue.

It is not always necessary to put wood stripping (also called furring strips) under a metal roof, but some metal roofs require stripping to work efficiently. For example, you must use furring strips when installing metal over shingles in order to connect the shingles to the metal roofing. These strips are made of metal or wood. They create thermal breaks and provide a solid frame to which you can attach the metal roofing. A lack of wood stripping can cause condensation issues under certain roofs, so use the roofing manufacturer’s specifications as your guide.
