What is Roof Insulation?
Roof insulation is defined as a board-type material that is usually of low to medium density and is made of cellular glass, foamed plastic, mineral fibers, wood fiberboard, lightweight concrete, or other materials, either of the sides of which can be faced with another material; it offers thermal protection in a roofing system.
It shields you from the sun, wind, snow, and rain as well as provides warmth and coolness depending on the season. Because of its critical role, adding insulation to your roof will help extend its life and performance, particularly during various seasonal changes.
Benefits and Importance of Roof Insulation
Here are a few reasons why you should insulate your home or property:
- Energy and Cost Savings – With effective insulation, you will save both money and energy. The roof is responsible for about 35% of a building’s heat loss. You save both when an effective insulation system is properly installed by the right professionals at your property.
- Provides an additional layer of protection – It can prevent long-term damage caused by moisture and ice dams.
- Lessens your carbon footprint – Among the most important energy-saving investments you can do in your home is to insulate your roof. According to studies, effective insulation reduces CO2 emissions, which aids in the fight against air pollution.
- Mold prevention – Insulation is the most effective tool for mold prevention. Because insulation regulates a building’s thermal conditions that have a direct impact on mold growth.
Moreover, It’s important to know that inadequate insulation is one of the leading causes of unbelievably high electric bills in most homes. Without adequate insulation, hot and cold air would then freely flow out of (and into) your home. This reduces your home’s energy efficiency, raising your heating and cooling bills. Aside from the cost, poor insulation can cause mold and mildew growth and reduces the value of your home.
Roof insulation is especially critical for a home’s energy efficiency; properly insulating your roof will save you more money than you thought. Roof insulation will lessen your energy consumption, meaning you are keeping money in the bank and protecting the environment by leaving behind a smaller carbon footprint. Roof exposure to rain, sun, and snow can damage and interfere with your house’s insulation and energy savings.
Key Considerations Before Installing Roofing Insulation
Roof insulation is becoming increasingly popular. Regardless of the type of roofing system you have, it can provide you with a number of long-term benefits. Here are some key considerations before getting started with your roof insulation.
Costs of Insulating material
Insulating materials can cost between $1700 and $2100, according to Home Advisor. The primary cost-influencing factors are as follows:
- Your insulation’s type and material
- Your attic’s house size
- Contractor Fee
Note: If you need to insulate around electrical boxes or wires, an electrician may be required as part of the process.
Choose Your Insulation Type and Material
There are a variety of materials readily available for roof insulation, some of which are relatively inexpensive and can be installed with or without the help of professionals. All of the insulation options available to homeowners can prevent thermal energy transmission from one area to another. The effectiveness of each type is dependent on the particular roof type, construction, or needs of your home. Here are the types of roof insulation available for you.
- Matting Insulation or Blanket Insulation
It is considered to be the most popular and easiest to install. These are typically supplied in foil-backed rolls or rafters and are held together by timber battens installed between the rafters or joists. Blanket insulation is typically made of mineral wool or glass wool but it can also be made of plastic fibers and natural fibers such as sheep’s wool and cotton.
- Foam Boards
These are rigid panels of insulating material that are cut and then installed. Polystyrene, polyurethane, and polyisocyanurate are the most common materials used to make foam boards.
- Radiant Barriers
According to studies, Radiant Barriers are the type of roof insulation that can easily absorb a lot of heat. They are much more effective in hot climates because they limit heat transfer through thermal radiation and they’re easily fastened to the rafters’ undersides.
- Blown-In Insulation
This type of insulation entails blowing cellulose mineral fibers into an empty space in the roof area. These require specialized skills and expertise, but they are also extremely quick to install and work well in spaces with limited access, such as the gaps between roof support beams.
- Spray Foam Insulation
Spray foam is made of polyurethane and sprayed as a liquid, slowly spreading and expanding to up to 100 times its initial volume. When it hardens, it forms an effective and powerful thermal and noise-insulating layer.
Know Which is Better for Your Roof Insulation: Inside or Outside?
Did you know that your roof can be insulated from the inside or the outside?
There are numerous advantages to insulating your roof from the outside. Aside from avoiding the need to empty your attic rooms, insulation from the outside does not reduce and doesn’t eat up your living space, and it reduces the chance of thermal bridges. If you are renovating or fixing up a facade or a roof, this is the best option for you. Among other advantages, this technique makes the frame visible from the attic.
On the other hand, Inside Insulation is a viable solution and highly effective in new construction. This method of roof insulation is perfect if you have not yet finished the attic and it allows you to maintain the roof covering system intact.
Insulation costs have risen substantially in the last five years, and insulation is now considered necessary by building codes in many states in the US. Insulation must now be installed in any new facility or building. So, given its importance in energy savings and inclusion in many building codes, Roofing Insulation is evidently more than just an option now.
So, make sure to have your roof inspected on a regular basis by professionals—this will keep you informed of any problems with your insulation, as well as any underlying problems with your roof, and its general health.
