What Is Metal Roof Insulation
November 30, 2021
Ever wondered what, in colder areas, provides insulation to the entire house? This question may strike your fancy, primarily if you reside in a relatively hotter place.
If it does, continue reading this article until the end, as we will lay down different details relating to metal roof insulation, how it can be installed, why you need it, the pros and cons, and others.
Types Of Bulk Roof Insulation
Spray Foam Metal Roof Insulation
The most common type of metal roof insulation available on the market is spray foam insulation. Advanced Insulation and MBCI, are two of the largest metal roofing manufacturers. The companies both sell an open-cell foam that is fairly cost effective. However, closed cell foam is often a better choice because it gets twice the R-value per inch. Furthermore, closed-cell foam is a vapor retarder and open-cell is more vapor-permeable. A vapor retarder prevents water from condensing when it makes contact with the metal roof.
Water condensation is one concern with insulating metal roofs. Corrosion is another. The foam can sometimes cause the metal to corrode. Only the roofing manufacturer can tell you if corrosion or condensation will be problems. They can also tell you if insulating the roof will violate the warranty. You can’t rely on your roofing contractor’s opinion only. In order to protect your roof’s warranty, you must check with the manufacturer.
One reason it may make sense to insulate a metal roof is to help fight global warming. Global warming is linked with, among other things, melting polar caps, animal extinction and drastic changes in temperature. A well insulated roof can reduce energy requirements for a home. This not only helps with heating bills, but it also helps the environment. Plus, many spray foam insulations are made from recycled content so they are environmentally sensitive from cradle-to-cradle.

Roof Insulation Against Radiant Heat And Retaining Heat
As the name suggests, roof insulation is a great way of removing excess heat while also creating a barrier against heat that might penetrate the interior of the house. The most commonly used roof insulation is in the form of the roof insulation foil which has been known to reduce heat build-up during summertime at 97% while also retaining heat inside the house during much more colder seasons.
So what are some of the benefits of roof insulation against warm and cold climates?
- Roof insulation can retain heat during winter by creating a warmer atmosphere inside.
- If properly installed, the amount of electricity thats being expended to keep homes warm and hot is severely reduced which means less energy expenditure.
- Once roof insulation is installed in larger buildings, the number of HVAC equipment can be reduced which can help save money and space.
- One of the main reasons why mold, rot, and mildew form inside dank homes is because of the build-up of moisture and heat. By maintaining good roof insulation, humidity and moisture are reduced to levels that will stop fungi from growing.
Understanding Metal Roof Over Shingle Insulation
Insulation is an important factor to consider when it comes to installing a metal or shingle roof. Surprisingly, its a conversation that doesnt take place enough. Its such a crucial element because it helps determine how well your roofing material conserves energy. Both shingle and metal roofs are constantly exposed to the sun. Therefore, you can expect both materials to reflect, absorb and release heat. Yet, the rate at which each roofing materials do that can help homeowners determine whether its the best fit for theyre homes.
Huntsville AL is known for its warm weather. In fact, during the summer months, the average temperature is at least ninety-one degrees. Considering a roofing materials insulation properties is essential for keeping your home cool.
Metal Roof Insulation
Metal roof insulation addresses two major goals stabilizing the interior temperature and help to prevent material from collecting under the roofing material. Yes, providing a layer of insulation under a metal roof is imperative because metal is naturally a better heat conductor than wood. Quality insulation helps a home retain heat in the winter and keep cool when the temperature dips.

How Do Moisture And Condensation Pose A Threat To My Building
Condensation occurs when there is a significant difference in temperature between the inside and outside of your building.
Following this, moisture collects around the unprotected areas typically the roof and wall and seeps further into your building.
Moisture stimulates the growth of rust and mould, which are detrimental to your building as they severely weaken the infrastructure, causing further damage in the long-run.
How it works is the insulating material acts as a barrier that prevents the cold air from diffusing into your building, as well as the warm air inside from leaking out.
Simply put, installing insulation is akin to implementing an all-in-one solution for a large number of specific problems caused by weather conditions.
What Is The Cheapest Way To Insulate A Metal Shed
Properly insulating your metal shed not only helps control the temperature but also helps prevent condensation and water from getting inside of it. Fiberglass batts are typically the cheapest option, and theyre also easy to install. Rigid foam boards are considered a cheaper alternative to spray foam. And spray foam, although it may be more expensive, may offer the best R-value. While fiberglass batts are usually the cheapest, property owners may want to consider other options to find the best one for them.

He thought it would be a great place for a workshop. But when winter came, he realized that unless he wanted to freeze, he needed some insulation. The next step was to find out how to insulate a metal shed.
Metal sheds without any insulation amplify the exterior temperature. In Fall and Spring, warm days followed by cool nights results in condensation. Usually, this forms on the interior surfaces of the metal shed. Condensation means you will have water in your shed not good! Properly insulated metal sheds negate this problem.
Insulating your metal shed is not difficult, but can be time-consuming, so plan on spending most of the day to do it right. Heres how:
- Measure the wall, ceiling, and floor area of your metal shed.
- Remove internal wall sheathing, if necessary
- Using closed-cell spray foam, coat the walls in 2-inch layers
- Let the foam dry between layers

Cons Of Fiberglass Loose
Health concerns – The small fibers of glass in the insulation can irritate your skin and can cause lung cancer over time if inhaled. It is recommended that you wear masks and other protective gear.
Not good for cold climates – The U.S. Department of Energy states that when temperatures reach below freezing, fiberglass loses up to 50% of its R-value because of the extreme difference in temperatures between the interior and exterior of the house.
Insulation Options That Are Available To You
When it comes time for you to look at insulation options, there are a lot of different products that will be available to you. Some of the most popular include:
Spray polyurethane foam is the only type of insulation that has been approved by Energy Star for use in attics and crawl spaces. SPF does not absorb moisture, thereby eliminating any potential for mold growth. Spray foam also helps reduce energy consumption and noise transmission.
Disadvantages of Spray foam include its high cost and the fact that it can take a long time to install.
Rigid insulation boards, such as extruded polystyrene , are made of plastic that is manufactured into large sheets or panels. Rigid insulation is easy to cut and install.
It resists moisture and does not rot or decay, thus providing a long-term solution for insulation. However, the high cost of the material limits its use in commercial applications.
Advantages of rigid insulation boards include ease of installation and lack of susceptibility to mold growth. Disadvantages include the tendency to absorb moisture over time if installed away from a vapor barrier and high cost.
Batt insulation is made of loose, fluffy fibers that are compressed into batts or rolls. It is the most common type of residential insulation.
Fiberglass batt insulation comes in various thicknesses for different applications, such as walls and attics. In addition to fiberglass, bats also are made from recycled newspaper, rock wool, and cellulose.

The Best Option For Insulating Metal Shed
Although you can purchase DIY closed-cell spray foam kits at your local home reno store, professional installation is best. These days, professional spray foam installation is much cheaper than in the past. Paying an expert to spray your metal shed with closed-cell foam will not break the bank.
DIY spray foam kits provide all the tools you need to complete the job. However, the applicators and nozzles often break, and many report having difficulty getting the right consistency of foam to come out of the applicator. Save yourself time and hassle and pay a professional. It might cost you $500 extra dollars, but the quality of the job will enhance the life of your metal shed.
Lastly, the application of spray foam on a clean surface is critical. Spray foam is ideal because of its coverage ability. It covers every last nook and cranny, keeping moisture and air out of your shed. Clean the wall surfaces completely and ensure they are dry before applying spray foam. If walls have any moisture, the spray foam can trap that moisture and rust can form on the interior or exterior shed surfaces.
