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:
Attic/crawl spaces: R30 to R60
and crawl spaces with existing insulation with 3- to 4-inches of insulation:
R-25 to R38
R19 – R25
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
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
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
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
Regulates interior humidity, further enhancing
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.
