People often focus on particular home features, causing them to neglect other important components, particularly in roofing systems. Insulation is one crucial aspect of a good roofing system, but it’s also one of the most overlooked.
Continue reading to learn more about the significance of proper insulation to your roofing system.
Understanding Roof and Attic Insulation
Although roof and attic insulation are sometimes used interchangeably, they are distinct from each other. Roof insulation is either expanding foam or cellulose made from recycled paper and is put directly beneath the roof deck. On the other hand, attic insulation is installed on or beneath the attic floor and, in addition to the two insulation materials already mentioned, can be made of blanket or loosely applied fiberglass.
Roof insulation slows down thermal transmission between the roof and the outdoors, reducing radiant heat absorption in the summer and preventing ice-dam formation in the winter. Attic insulation, in contrast, slows down thermal transfer between the indoor spaces and the attic, preventing heat from escaping into the attic and reducing heat loss during the winter.
The Benefits of Proper Insulation
- Extends your roofing system’s life. Roofers say warping and other issues brought on by trapped heat can be avoided with attic insulation and adequate roof ventilation. Moreover, mold can grow in warm, humid environments and spread covertly to other areas in the house.
- Protects the roof from ice dams. Without adequate insulation, heat from the inside of your home leaks into the attic, making the roof excessively warm. Furthermore, the snow and ice on the roof surface may thaw and then refreeze along the eaves and gutters, which can be a problem during the colder months.
- Reduces heating and cooling costs. Attic insulation is a barrier between your living spaces and the attic, slowing down thermal transmission between these two areas in your home. This makes your interior easier to heat or cool, reducing the strain on your HVAC system.
