Are you noticing your utility bills skyrocketing? Is your home too hot in the summer, and too chilly in winter? If your house isn’t as energy-efficient as you’d like, one of the main culprits may be right over your head—in your attic!
Roof insulation may be out of sight, but it shouldn’t be out of mind—because it plays an essential role in keeping your home cozy all year round. Here’s how to think about roof insulation and ensure that it’s performing at its best to keep your home comfortable and energy efficient.
Why Improving Your Roof Insulation Matters
Though you might not realize it, the insulation in your attic does a lot of work. Insulation reduces heat loss during the winter and lessens heat gain in the summer, so that your living spaces stay a steady, even temperature without driving up your energy bills.
In addition, roof insulation acts as a sound barrier, lessening noise intrusion from outdoors and keeping your home quiet and soothing. Proper insulation also helps your roofing system to function optimally. And it keeps your attic at a consistent temperature, which is better for anything you are storing up there.
6 Practical Steps for Boosting Roof Insulation
Adding to your roof’s energy-efficiency involves more than simply installing a layer of insulation. Here’s what you can do to make your insulation thorough and productive.
1. Assess your current needs.
Do a thorough walk-through of your attic to look for what you need. Are there spaces where insulation is too thin, or perhaps even missing? Is there an area that was simply never insulated when it was first built? If the lack of insulation is minor, you might be able to address that quickly and easily.
On the other hand, if you had a roof leak, roof damage, or a major pest infestation, you might be looking at the need to have insulation fully replaced. If insulation has retained moisture and is wet, it won’t work properly and should be removed and replaced to avoid mold growth.
2. Seal air leaks and address repairs.
New insulation can’t fully do its job if your roof has spots that create drafts. If you notice sunlight sneaking into your attic, that’s a sign of missing or damaged roof shingles which you’ll need to address. Pay close attention to areas around vents and chimneys—if you see gaps or cracks, you’ll want to replace caulking and/or add flashing.
3. Choose the right insulation material.
As you select new insulation, a general rule is to compare R-Values—a number which indicates how effective the insulation is at resisting heat flow and preventing energy loss. A higher R-Value means the insulation is better at keeping your heated and air-conditioned air inside your home, resulting in a more comfortable, energy-efficient living space in cold climates like ours.
Once you’ve looked at R-Value, you can also consider different types of insulation—such as fiberglass, cellulose, spray foam, mineral wool, and insulation boards. An expert team (like ours!) can guide you through your choices to help you make an informed decision.
4. Install insulation properly—ideally with professional assistance.
Though it might seem simple, installing insulation takes precision and expertise. This is because a number of factors can affect what type of insulation you use and how you place it. Your roof’s slope, design, and ventilation system should be taken into account. Building regulations and municipal codes must be complied with. Insulation needs to be cut to fit snugly, or blown evenly into place for consistent thickness. Proper safety equipment such as eyeglasses and masks should be worn. Experienced professionals (like us) will know exactly what is required to do the job right the first time.
5. Perform regular checkups and maintenance.
It’s tempting to think of installing insulation in the attic as a one-and-done activity. But just like any other area of your house, your attic should be regularly inspected to be sure everything is in proper working order. Once or twice a year, check your attic, the underside of your roof, and your insulation. Look for any signs of compromise or damage that ought to be fixed. If insulation looks thin, worn, damp, or ripped, it needs attention.
Keep an eye out for pest intrusion as well. If you see droppings, it’s a good bet that your insulation has been damaged—because pests like to dig through insulation to build nests and create pathways in and out of your roof, and this ruins your insulation’s ability to work properly. You’ll want to have the pests removed, and then re-insulate and make repairs to keep them out.
6. Consider other ways to ensure your roof’s energy-efficiency is thorough.
Insulation is a vital element in a roof’s efficiency—but it’s not the only one. Other factors can also help keep your home cozy throughout the year. Proper roof ventilation keeps your attic dry and free of mold and mildew—resisting moisture accumulation. Old roofing systems become less efficient as they wear down with age—so a roof replacement may be in order if your current one is past its prime. Installing dark shingles helps to retain heat, a handy factor in keeping homes warm in snowy Minneapolis-St. Paul winters. All these options can make your house more efficient, allowing your insulation to do its job.
