Insulating a metal shed roof with rigid foam can be done one of three ways by laying the board prior to applying the roof by removing the existing roof and installing new foam board or by insulating the existing metal roof from the inside.

Insulating a roof with rigid foam.

Rigid foam boards come in different material compositions varying thicknesses and different insulating r value properties. It can be applied on the roof floor and walls and it s most widely used in structural insulated panels and insulated concrete forms. Eps is by far the most versatile of the three rigid insulation options. A continuous layer of rigid foam insulation in wall and roof assemblies leads to lower energy consumption an environmental plus to be sure.

Rigid insulation layers exterior to existing roof sheathing must provide sufficient thermal insulation r value to control condensation risk see climate specific guidance. Eps is also the most inexpensive of the three types of rigid foam insulation while also meeting the required building and energy codes. There are lots of different ways to insulate this type of roof but one of the best methods calls for the installation of rigid foam insulation above the roof sheathing. Nail it around the edges with roofing nails.

Start at the bottom of the roof and place the first piece of rigid foam insulation against the metal flashing starting at the center line. There are at least two good reasons why this approach makes more sense than installing the insulation under the roof sheathing. Install rigid insulation board in multiple layers with joints offset vertically and horizontally between adjacent layers.
