Attic insulation can last 80 to 100 years, although it loses its energy efficiency benefits over time. The professional advice of certified attic specialists is to update it every 15 years to ensure that it continues to function properly. Rodents love attics because they're protected from the elements, making them warm and dry, they're protected from predators, and they have lots of great materials for nesting, in the form of insulation or stored belongings. If you notice mold growing on the insulation material of the attic or on surrounding surfaces, such as the structure surrounding the roof plane, you will definitely need to consider removing and replacing the attic insulation.
Removing the old insulation from the attic before adding a new one will facilitate the proper installation of the new insulation materials, ensuring that they are distributed evenly and are effective in keeping the house warm in winter and cool in summer. Some of the most popular types of insulation for attics are fiberglass blocks, loose filler cellulose, and aerosol foam. What you may not know is that if you have a leaking roof, you probably need to change your attic insulation as well. Proper attic insulation can help keep your home cool in summer and warm in winter, and minimize drafts and noise pollution.
Aerosol foam insulation can reach these spaces and fill them, creating an airtight seal that helps keep the attic space warm in winter and cool in summer.

However, the insulation of fiberglass blocks can begin to fall off after 15 to 20 years, so if the insulation was installed in blocks more than a decade ago, it might be time for a home energy inspection or audit. In general, it's a good idea to check your attic insulation every 5 to 10 years to ensure it's still in good condition.
Leaving the old insulation in place will mean that you will continue to benefit from it, and at the same time, you will have an additional layer of insulation on top. Limit access to the area and ask a person trained and certified to work with asbestos attic insulation to professionally inspect the insulation, which may be contaminated. From a house with too many drafts to increasingly increasing energy bills, don't hesitate to look out for these top signs that attic insulation may need to be replaced. In the case of homes with insufficient or damaged insulation, replacing attic insulation can restore energy efficiency and comfort.
Similarly, if your attic is poorly ventilated, heat and humidity can cause the insulation to deteriorate.
