• Insulation Is Part Of An Energy Efficient Roof

  • insulation is part of an energy efficient roof

    The direct elements of a roofing system include things like shingles, tiles or metal, flashing, underlayments and downspouts. However, insulation also relates to your roof’s ability to perform as designed. Adequate insulation helps to reduce condensation, which minimizes the potential for moisture damage and future leaks. A well-insulated attic space also improves indoor comfort, and indoor air quality making your whole home more energy efficien.

    If you’re planning a major roof repair or replacement, consider replacing or upgrading your insulation at the same time. Together, these structural renovations will reduce heating and cooling loads on your HVAC, lowering overall utility spending.

    Upgrading Attic Insulation Improves Roof Function

    Here are some of the ways adequate attic insulation will make a difference in your roof’s function, making your home more energy efficient.

    Note: The term adequate insulation refers to insulation types and quantities as recommended by the US Department of Energy’s current insulation guidelines for your region.

    Adhere to energy.gov’s Zone 3 insulation R-Value guidelines

    The Bay Area falls under Zone 3. This means your home’s insulation R-values should be as follows:

    • Uninsulated Attic/crawl spaces: R30 to R60
    • Attics and crawl spaces with existing insulation with 3- to 4-inches of insulation: R-25 to R38
    • Floor: R19 – R25
    • Walls: R-5

    The higher the R-value, the better the insulation value. Higher R-values cost a bit more, but typically pay for themselves by way of energy savings. Your insulation contractor will evaluate your household occupancy and lifestyle, as well as your preferred thermostat settings throughout the year, to determine which R-values make the most sense for your home.

    Repairing or replacing a roof offers an ideal opportunity to assess your current insulation situation. A certified contractor can evaluate your house’s current R-value and recommend whether additional R-value is needed and appropriate types of insulation.

    Minimize moisture damage and future leaks

    There is an intimate relationship between your roofing materials and attic insulation. A well-designed roof protects a home from exterior moisture for decades at a time. However, it can’t protect itself from interior moisture damage (by way of condensation) without adequate insulation.

    So, assume you restore your roof, but neglect the attic and crawl space insulation. Now you have a situation where condensation can form on the interior roofing surfaces. Over time, these surfaces begin to warp and break down from a perpetually soggy state. Mold and mildew accelerate structural damage and – before you know it – you’re prone to leaks.

    Installing the right type and quantity of insulation provides a better, overall moisture barrier by preventing condensation and elevated humidity levels in the first place.

    Adequate insulation optimizes interior comfort

    Not surprisingly, your insulation does much when it comes to optimizing interior comfort, helping to stabilize temperatures, so they reflect your desired thermostat setting. While energy-efficient roofing materials are designed to minimize solar heat gain in the summer and optimize heat absorption in the winter – it’s up to your home’s insulation to regulate interior temperatures at the same time.

    The combination of a well-designed roof and upgraded insulation means less work for your HVAC to keep temperatures comfortable, and you’ll notice that via reduced energy spending.

    Improve interior air quality

    Because attic insulation minimizes moisture accumulation in attics and crawl spaces, it also regulates indoor humidity levels. The Bay Area’s proximity to the ocean, combined with cooler, rainier winters/springs, makes us especially prone to mold and mildew development without proper attention to sound structural design.

    Once you’ve updated the insulation under your roof, you’ll notice humidity levels begin to balance out, and this will improve your indoor air quality. Focusing on healthy indoor air quality is especially beneficial in households that suffer from chronic allergies or other respiratory conditions.

    Enjoy the benefits of an energy efficient home

    In an era where energy efficiency is a priority, complete roof systems and sound insulation are foundational to that goal. Your new roof, air sealed home and insulation work together to support what’s referred to as “whole-home energy efficiency.”

    This trifecta – roof, air sealing, insulation – is powerful because it:

    • Minimizes heat gain/loss from your home during peak seasons
    • Regulates interior humidity, further enhancing interior comfort
    • Reduces the load on your HVAC system, which reduces wear-and-tear, its energy consumption and overall maintenance/repair costs
    • Improves interior air quality
    • Reduces the need to use the HVAC system at all during the mild seasons of the year
    • Minimizes the risk of leaks or moisture damage that compromise your home’s structural integrity

    The combination of the above means whole-home energy efficiency, and that efficiency makes itself known in terms of utility savings and fewer repair needs over your home’s lifetime. That means more money in your pocket.
