Are you looking for ways to make your home comfortable and also spend less on energy bills? Then, all you need is polyurethane spray foam for your metal roof insulation. In this article, we will discuss the benefits of an insulated metal roof, the advantages of polyurethane spray foam, and the cost of using spray foam for metal roof insulation.
Why is Insulation Essential for Metal Roofs?
Metal roofs can withstand harsh weather conditions but are highly energy inefficient unless insulated. Because it is not thermally insulated, the metal roof causes temperature fluctuations in your home during winter or summer.
The benefits of metal roof insulation include the following:
The Heating, Ventilating, and Air Conditioning (HVAC) System in your home consumes so much energy to maintain a stable temperature. In this respect, metal roof spray foam insulation saves energy by making your home air sealed, thereby reducing the amount of energy consumed by the HVAC system.
Metal roof insulation helps maintain a stable temperature in your home during winter or summer. Using spray foam for metal roof insulation reduces heat transfer by creating a barrier between your home and the surrounding environment.
Protection Against Condensation
Metal roof insulation protects your home from condensation by sealing air gaps and cracks. Condensation occurs due to air exchange from outside, and insulation helps reduce air infiltration, which can lead to moisture buildup.
Metal roof Insulation increases the durability of your home by providing an extra layer of protection against moisture and air infiltration. In addition, by insulating your metal roof, you can increase your roof's structural integrity and stability.
Improved Indoor Air Quality
Insulation improves the air quality in your home by reducing air pollutants like dust and fumes from the environment from entering your home. Insulation also reduces the growth of mold and allergens caused by moisture buildup by sealing air gaps in your home.
Another important benefit of insulation is that it makes your home soundproof by reducing noise from outside.
Increased Building Value
Insulation increases the resale value of your home because buyers would rather buy an insulated house that is energy efficient and saves energy costs.
What is the Best and Cheapest Way to Insulate a Metal Roof?
Spray foam is the best and most cost-effective way for metal roof insulation. Spray foam reduces air leakages in metal roofs and makes your home air sealed. Spray foam is more durable and long-lasting than other methods of insulation. In addition, spray foam is cost-effective because it saves energy costs in the home in the long run, reducing the energy spent on heating and cooling the home.
Advantages of Using the Polyurethane Spray Foam Can for Metal Roof Insulation
Spray foam is a polyurethane-based insulation material made from two chemical products and used to seal air gaps and cracks in buildings. Spray polyurethane foam is applied easily using high-pressure cans.
The advantages of polyurethane Spray Foam can for metal roof insulation include the following:
Spray polyurethane foam offers the highest R-value of the different insulation methods. R-value measures the resistance to heat transfer of insulating material. A high R-value means the insulating material will offer better thermal insulation.
Easy to apply
Polyurethane spray foam can be easily applied with the right equipment and guideline. As a DIY project, you can insulate your roof or other parts of your home.
Cans of spray foam insulation are portable, lightweight, and easy to transport, making them ideal for use on-site.
Air and Vapor Barrier
Using polyurethane spray foam cans for metal roof insulation helps create a vapor barrier or air barrier in your home. You can reduce moisture and vapor in your home using spray foam insulation.
Fills Gaps and Irregular Spaces
Using spray foam cans makes it easy to fill gaps and cracks in irregular spaces in your home. Unlike other insulation methods, polyurethane spray foam cans are portable and can reach difficult places in your home.
Spray foam insulation is long-lasting and can last more than 25 years when installed properly. Also, they maintain their insulating properties throughout their lifespan, maintaining effectiveness and durability for many years.
Cost-effective (cost-effective option for DIY projects.)
Using polyurethane spray foam cans is a cost-effective option when you want to insulate your home. Insulating your home as a DIY project with a polyurethane spray foam can is less expensive than hiring a professional.
What is the Metal Roof Insulation Cost Per Sq Ft with Spray Foam Can?
Spray foam insulation is expensive when you hire the services of professionals. Professionals charge based on the size of the metal roof, labor, your desired R-value, and the job's difficulty. Many homeowners reduce the cost by carrying out metal roof insulation as a DIY project.
The average cost of metal roof insulation per sq ft with spray foam can cost between $1.1 to $1.2. You can insulate your metal by getting a Fast Coat Spray Foam Can and other necessary equipment.
How Thick Should Spray Foam be on a Metal Roof?
Generally, a minimum thickness of 1-inch is recommended for metal roof insulation. The thickness of spray foam on a metal roof depends on your desired R-value, climate, and building code requirements. To increase the R-value of your metal roof insulation, you can use a thicker layer of insulation, like 2-inch, which provides an R-value of R-15.
What is the R-Value for Roof Insulation?
The R-value of an insulating material represents the measure of resistance to heat transfer of that material. The recommended R-value for your roof insulation depends on significant factors like climate and your location’s building codes. Check the climate chart to see the recommended R-value for your location. A high R-value will provide more thermal insulation to your roof.
It is important to know that spray foam insulation is divided into two; open-cell and closed-cell spray foam insulation. Closed-cell spray foam offers a high R-value and is preferred over open-cell spray insulation. Check out How to Choose: Closed-Cell vs. Open-Cell Insulation Foam to see the difference between both types of insulation.
Spray Foam Metal Roof Insulation FAQs
Is it Recommended to Insulate Under a Metal Roof?
It is recommended to insulate under a metal roof to make your home comfortable and energy efficient. You can also reduce noise, prevent condensation, and improve air quality in your home when you insulate under your metal roof.

The product was very simple to use and easy clean up with the can of cleaner.
The spray foam spray it on, just as they said it would. It covered as they said it would. Seems to be a very good product.
Works great . It is alittle hard to get even depth but is was working on filling the floor sill in my new basement. My house is existing so the house was lowered on to ifc wall. I got 18 cans did 136 feet by one foot by anywhere from 2inches to 4 inches thick. One thing I really like is if you need or want to stop you can. Just clean the gun with the spray which comes with the cans. Unlike froth paks I don't think you can stop after hour or more. Plus it only costed me about $350 compare to froth at 800 to 1000 dollars. The product I'd closed cell another good thing. Would buy and recommend to anyone.
I can’t use these tips on my standard gun, and I have to say they work really well.
This is a great alternative to using a “Froth Pak”.
Works really well sprayed my work van with it and ￼ easy to install notice a huge difference in road noise and temperature will be buying again in future
So much better than regular 'ole spray foam cans from the local store. The metal coated spray gun worked flawlessly, easy to clean up and the wide angle tip made for really fast, even spraying. I used to adhear rigid foam board (and get some extra r value from the layer of spray foam). Best of both worlds a sealed wall with the spray foam and 2" thick insulation with the foam board that is essentially glued into place by the spray foam. Probably better than a pro job and a fraction of the cost.
I filled some voids between deep fitting strips and the project went smoother than I had planned!
Easy to use highly recommended it
Great product saved me thousands easy to apply videos are great help
Excellent product superior to many others and has its own applicator device to keep your hands clean and making the application easy
These went on easily and I noticed the temperature difference immediately. Would definitely recommend!
Excellent material products on it ￼
The part that I ordered exactly what I needed shipment they did not take that long. I ordered it after three days at Aceel in it ASAP. Thank you guys.
Easy to use and makes a huge difference in the temp in our metal building.
