Metal Roof Insulation Keeps It Cool
Originally published 1/6/23; updated and re-written 9/5/24
As a homeowner in the south, you may have some questions about a metal roof in the summertime. Sure, they’re one of the best looking roof materials you can choose, but what about the oppressive heat? While the top of your metal roof can really heat up, metal roof insulation methods keep the inside of your home cool year round. The heat on top is a good indicator of metal roofing’s ability to reflect heat- a trait only multiplied by the correct type of metal roof insulation.
The following tips from Roof Experts will help you get maximum utility out of your roof insulation.
Metal Roof Insulation Options
1) Spray Foam Insulation
You can spray foam the attic floor and roof deck to help keep the heat out. The foam will create a barrier between your roof and the hot air, preventing the heat from transferring through. Spray foam insulation is a quick and easy way to improve your home’s energy efficiency.

2) Reflective Insulation
Reflective insulation reflects heat away from your home. It comes in rolls or thin sheets of aluminum foil that you can install directly on top of your metal roof. The light aluminum foil reflects heat away from your home. When choosing reflective insulation, make sure to get one specifically designed for metal roofs. Reflective insulation is easy to install, and you can use it in line with other insulation types.
3) Eco-Insulated Roof Panels
Eco-Insulated Roof Panels are a newer insulation type made from recycled materials. The panels are made up of used tires, plastic bottles, and other recycled materials. The panels are then compressed and bonded together to create a rigid board. Eco-insulated roof panels are an excellent option for metal roofs because they are water-resistant and will not rust or corrode. The panels also reflect heat away from your roof.
4) Thermal Insulation
Thermal insulation helps reflect heat away from your home, which keeps your metal roof cool. The most popular type of thermal insulation for metal roofs is fiberglass batting. Fiberglass batting is made from glass fibers bonded together with resin. You can install the batting in various ways, including rolled, blown-in, or sprayed.

5) Apply a Cool Coating
Applying a cool coating is an unconventional roofing strategy that you can use to cool your place. Cool coatings are paint-like products that help reflect heat away from the surface. You can use cool coatings on any roof type, but they are most effective on metal roofs. There are several different brands of cool coatings available, so be sure to research the options before making a purchase.
6) Added Ventilation
Adding ventilation to your home is a great way to keep your metal roof cool. Installing vents in the attic will help circulate air and keep the temperature down. You can also install a ridge vent or gable vent to improve airflow.
