Attaching Foam Board Insulation to a Metal Roof: Step-by-Step Instructions

Now that we have prepared the metal roof for insulation, it’s time to attach the foam board insulation. Here are the step-by-step instructions:

  1. Measure the panels: Using a measuring tape, determine the length and width of the area to be covered. Measure the insulation panels to fit the area, making sure to leave a gap of 1/8 inch around the edges for expansion.
  2. Cut the panels: Using a straight edge and a utility knife, cut the foam board insulation panels to the measured size. Be sure to make straight cuts, as uneven edges will create gaps and reduce the effectiveness of the insulation.
  3. Apply the adhesive: Apply a generous layer of adhesive to the back of the insulation panel, covering all edges and corners. Use a trowel or putty knife to spread the adhesive evenly, making sure to cover the entire surface area.
  4. Place the panel: Carefully position the insulation panel onto the prepared metal roof. Press down firmly, making sure the panel is level and properly aligned with the adjacent panels. Repeat this step until all the panels have been installed.
  5. Seal the gaps: Once all the panels have been installed, seal the gaps between the panels using foil tape. Cover the entire edge of each panel with tape, making sure to seal the joints and edges to prevent any air from escaping.
  6. Clean up: Once the insulation panels are securely affixed and sealed, remove any excess adhesive or debris from the roof surface. Dispose of any leftover material safely and properly.

Following these steps will result in a properly insulated metal roof that is energy efficient and well-protected.
