How to Insulate a Patio Pan Roof

Choose a roof insulation material. The material needs to be an R-value that is between 4.5 and 6. As the R-value goes up, the thermal resistance of the insulation gets better.

Count how many sections of rafters there are to be insulated. Divide your insulation material into sections to fit in your patio pan roof.

Wedge insulation between the first rafters. Make sure there is still room for air flow.

Secure the insulation with nails. Alternatively, if the material you chose to insulate with is not held down with nails, seal it into place with an epoxy. Install the rest of the insulation in the same manner.

Cover the insulation with wooden boards. Nail the boards into place with a hammer along the rafters.
