6 of the Most Common Signs Your Attic Needs New Insulation

Being a homeowner is a massive benefit because it’s where you can relax without worrying about anything else. However, it’s also a responsibility because you must make living conditions as comfortable as possible. Naturally, this applies to every aspect of your home, such as insulation.

Insulation is necessary for any home because it works as a barrier between warm and cold air. In short, it prevents your house from getting too cold or too hot. Of course, this also applies to your attic because it’s where the temperature can get extreme. Your attic can sustain heavy damage, which attracts mould or pests. For this reason, homeowners must know the different signs their attic’s insulation needs a rework, such as:

#1 – Energy Inefficiency

Energy is vital to a homeowner because it can impact his utility bills. If your home is energy efficient, you’ll save a lot of money in the long run. With that said, you need to know when your insulation is deteriorating. If your home is poorly insulated, your energy bills will be higher than usual.

Higher energy bills are a problem because they can affect your household budget. However, you should also know that energy efficiency can affect your air quality. If you want to ensure your attic is insulated, you must also think about energy efficiency.

#2 – Obvious Signs of Damage

Another reason why you should inspect attic insulation is because of its durability. If your insulation is deteriorating, you’ll likely notice it because of its condition. A good indicator that you should check your attic’s insulation is because of the following signs:

  • Cracks in the ceiling
  • Moisture
  • Cave-ins
  • Water leakage

Most of these problems are noticeable if you carefully inspect your attic’s insulation. If you see any of these signs, you should schedule an inspection as soon as possible.

#3 – Roof Icicles

If your roof is leaking, poor attic insulation can be the culprit. If there’s a roof leak, you can expect icicles to form in your attic. This is because of the ice dam effect. Icicles are dangerous because they can fall onto you or your family members. Once you see icicles in your attic, you should schedule an inspection immediately.

#4 – Mold and Mildew Growth

Mould and mildew growth is a significant problem for your attic insulation. This is because it can leave stains on your attic’s insulation. Mould and mildew growth also attract pests such as rodents, so you might also need a pest inspection.

You should schedule an inspection immediately if you notice mould and mildew growth. You’ll also want to eliminate these conditions so that it doesn’t spread to other areas of your home.

#5 – Deteriorating Seals

The seals are a barrier between cold and warm air, so you should ensure it’s functional. If the seals aren’t secure, they may not prevent cold air from entering your home.

This can lead to temperature changes. In addition, it can also lead to moisture problems. If you have moisture problems, then you have to address the source of the moisture. If you notice leaking, you should repair any leakages so that moisture won’t develop in your attic.

#6 – Drafty Areas

Another sign of poor attic insulation is drafts or breezes. Drafts and breezes are noticeable because it’s unusually cold. You should inspect your attic carefully to see if it’s drafty or breezy. This is because attic insulation can deteriorate if it’s left untreated.

Beyond that, drafty areas can also lead to energy loss, so you should ensure it’s adequately insulated. If you notice any drafts or breezes, you should have your attic inspected immediately.


Functional attic insulation is important because it can affect your energy bills and comfort. If your home is under-insulated, you’ll have to spend more energy or be uncomfortable at home. All that matters is finding the suitable material to ensure that your attic, and by extension, your home, will be well-insulated.
