Keeping your home energy-efficient would be an enormous challenge without insulation.
Attic insulation is made from cellulose, mineral wool or both materials combined together. It prevents conditioned air from escaping and keeps outdoor temperatures from infiltrating your space and affecting your indoor comfort.
Unfortunately, for some homeowners, attic insulation is the least important feature of their roofing system. But if you ask a professional roofer, attic insulation should also be a priority because it can help extend your roof’s lifespan. Continue reading to learn the four benefits of attic insulation.
1. Reduced Risk of Leaks
Leaks that infiltrate your asphalt shingles and underlayment can cause extensive damage. These often start small, with moisture gradually eroding the roofing material. Without frequent roof maintenance, small leaks will worsen over time. Proper attic insulation provides additional protection from leaks and water-related damage, contributing to a longer roof lifespan. If your roof is not adequately insulated and it develops cracks or gaps, this could put your home at risk of significant damage.
2. Stronger Rafters
The rafters on your roof prop up the entire structure, holding your asphalt shingles or clay tiles in place. Insulation protects rafters and reduces the possibility of cracks and damage from extreme temperature changes. Wood rafters expand and contract when the temperature fluctuates, and an insulated attic can reduce the effects of temperature fluctuations.
3. Ice Dam Prevention
Ice dams form when water on the warmer parts of the roof melts, and then refreezes when the snowmelt reaches the colder spots. A well-insulated attic prevents ice dams by ensuring your roof maintains a consistent temperature.
4. Improved Energy Efficiency
The most important benefit of insulation is reducing the temperature lost or absorbed through the building materials. This is accomplished by retaining indoor temperatures and preventing outdoor temperatures from affecting your space — which allows your HVAC system to work more efficiently. Many homes with attic insulation report lower utility bills per month after installation.
