Roofing Insulation 101

Not all roofing materials that are available to the masses today have superior insulating properties. Some, in fact, are excellent heat conductors, making heat transfer from the indoors to the outdoors far too easy. Of course, that means less energy efficiency and higher heating and cooling bills. As a result, there is an obvious need for something else to stop that flow of heat. This is where an under layer, which defends against heat transfer at the roof, comes in handy.

Insulation on the roof can drastically increase a home’s efficiency, thereby having a big impact on heating and cooling costs throughout the year. There are several different types of roofing insulation available and each comes with a distinct list of pros and cons. Relatively speaking, the upfront cost is minimal compared to the cost savings over the insulation’s lifetime. -n the past fiberglass insulation batting was the material used for this purpose. However, there have been many health concerns tied to its use, particularly because of it containing formaldehyde. This chemical is a well known carcinogen, which makes the batting very harmful to those who come in close contact to it, particularly if it is inhaled. As a result, industry experts have developed an array of other insulation options.

The first alternative is recycled cellulose fiber, which is made from paper products, such as recycled newspaper. This insulation carries a higher R-value than fiberglass batting, which is to say that the measure of thermal resistance or the measure of heat transfer over the area of the insulating material is less than that of fiberglass batting. There are many factors that can affect R-value, such as thickness of the material and the way in which it is installed, but when installed per manufacturers guidelines, cellulose wins out. However, there are a couple of disadvantages. Recycled cellulose is a blown-in insulation and not appropriate in all homes. It also costs more to buy and install. It also requires a treatment of boric acid in order to be considered fire resistant. Boric acid is not harmful and is used in many other applications, such as antiseptics and insecticides.

On the other hand, recycled cellulose has many other advantages as a roofing insulation. It is an excellent pest repellent and offers natural sound proofing.

Recycled denim is another, newer form of insulation. Unlike cellulose, it is available in large, easy to install rolls, rather than having to be blown in. This type of insulation is exceptional at holding heat and it also provides sound absorption. The downside, again, is that it must be treated with boric acid to repel bugs, rodents, and fire.

Soy insulation is becoming increasingly popular for its hardiness and for the fact that is is directly derived from nature. It is manufactured from soy bean oil and must be sprayed into the underside of the roof. It expands upon contact to fill cracks, crevices and other imperfections, and then it hardens there. Soy insulation is naturally flame resistant and boasts a very long lifespan; it will continue to work as long as the home stands.

Sheep’s wool also works well as insulation and is another nature-made product. It is, in fact, arguably the best insulator. However, it also carries the highest price tag which is why it is not often requested for roof repair in Irving, TX. That being said, however, sheep’s wool is naturally fire retardant and it also repels moisture, which means it won’t be harmed in the time that it takes to hire a professional for roof leak repair. The wool won’t irritate the lungs of those installing it like some of the other varieties of insulation and is highly eco-friendly, as it requires very little energy to produce, boasts a long life, and is fully recyclable.
