How Much Does a Roof Insulation Cost?


Fiberglass batt insulation has been the preferred insulation material for new constructions for many years. However, homeowners are switching to better insulators that last longer. It’s worth upgrading to better insulation if your HVAC system is clogged up and you want a more comfortable house. You can save money on HVAC repairs and maintain your home’s comfort year round by updating your insulation.

The size and type of insulation that you choose will affect the cost of attic insulation. This cost is offset by the monthly energy savings. A good pitch or flat roofing insulation will typically save you 15-20% on your monthly utility bills. And, quality insulation can last decades before needing to be replaced. A professional roofer will inspect your roof and advise you when it is time to add insulation. You can also get an estimate of the cost of insulating your attic area.

Different types of insulation

It is best to seek professional advice when choosing the right insulation for your home. The decision will be influenced by your budget, your local weather, your space, and the roofing material. The most common types of insulation are:

Blown-in cellulose insulation

Cellulose insulation is made from recycled paper and wooden materials, which is a far better choice than traditional fiberglass batt insulation. When properly installed, blow-in cellulose insulation can reduce fire damage. It can become very compacted, so there is almost no oxygen, which can slow down the spread of flames. Your materials will cost you approximately $1.40 per square feet. However, this will vary depending on your material’s R-value. Because of the potential for allergic reactions, some people may need to choose a material that is more allergy-friendly.

Spray foam insulation

Spray roof insulation foam has become a very popular choice for insulation. It provides an excellent air- and moisture barrier and will not shift or fall once it is dried. Although this type of insulation is easy to install, it can be messy and more expensive. Spray foam can be inhaled and irritated by the skin. Protective gear is required. Spray foam can only be applied when it is sufficiently warm to cure. Spray foam is more expensive than other options. You can expect to pay 65 cents to $1.50 for each square foot. It will depend on whether the spray foam is closed-cell or open-cell. An experienced roofer can help you choose the right spray foam for your needs.

Insulation with rigid foam

Although the rigid foam insulation cost per square feet is lower, it is less effective at sealing any gaps. It can be placed underneath rafter boards to provide additional protection. Spray foam is preferred by many homeowners to fill the gaps. This allows for the best price-effectiveness ratio. Rigid foam is more labor-intensive and requires careful cutting. Rigid foam insulation is as low as 45 cents per square feet.

Radiant barrier

Radiant barriers can be used to absorb heat from your attic, which will help you save energy and protect your home from heat loss during winter. This insulation is worth the investment, as Florida enjoys sunny weather most of the year. Radiant barriers are best combined with traditional insulation to save money all year. This insulation type can be expected to cost up to 30c per square foot.
