Attic insulation in Mesa, for SRP and city utility homes alike
A Mesa attic from the 1970s or 1980s has spent decades under the summer sun. We measure what's up there, then build it up toward what ENERGY STAR suggests for this climate. If your bill comes from SRP rather than the city, you may qualify for SRP's attic rebate.
By mid-afternoon in a Mesa July, the sun has been on your roof for hours, and the attic below is holding that heat. Insulation on the attic floor slows it on its way into your rooms. That's what R-value rates: the higher the number, the slower heat gets through. Maricopa County sits in IECC climate zone 2B, which is hot and dry, and ENERGY STAR sets its attic advice by zone.
Empty attic: aim for R49
If the attic floor is bare, ENERGY STAR's target for climate zone 2 is R49. We can get there with blown-in loose-fill.
Some insulation: add R38
Already have 3 to 4 inches? Then ENERGY STAR's advice is to lay R38 over what's there. We check the depth in several spots, since it can vary across one attic.
Our crews put in blown-in loose-fill, fiberglass batts, mineral wool batts, open-cell foam and closed-cell foam. Each suits a different space. The batt and blown-in page covers top-ups and new framing, and the spray foam page covers roof decks.

For SRP residential customers, the attic rebate may cover up to 75% of the job's cost, with a $600 ceiling. That's from srpnet.com, checked in October 2026. Read the current page yourself before you count on the money.
City power near downtown
Near Downtown Mesa, the City of Mesa runs its own electric utility. SRP's rebates are only for SRP customers, so a home on city power can't use SRP's attic rebate. Check the logo on your bill.
Older homes, older attics
Mesa's median home was built in 1989, and 29.0% of homes here went up before 1980. An attic that old may hold less than ENERGY STAR suggests today, so we measure before we quote.
A long, hot summer
Sky Harbor, the Phoenix station, averages 111 days a year at 100°F or above and 21 at 110°F or above. Temperatures vary across the Valley, but Mesa shares the same hot-dry climate zone.

FAQs: Mesa Insulation
Attic insulation questions from Mesa
How much insulation is in my attic now?
Take the depth in inches and multiply it by the material's R-value per inch. Each inch of blown fiberglass is worth roughly R-2.2 to R-2.7, and each inch of fiberglass batt roughly R-2.9 to R-3.8. A few inches of either falls well short of R49. At your free quote, we measure in several spots and show you the gap.
Does the target change between Dobson Ranch and Superstition Springs?
No. ENERGY STAR sets attic targets by climate zone, and all of Maricopa County is in zone 2. What changes from house to house is the starting point: how much insulation is up there now and what shape it's in. So every Mesa quote starts with a look in the attic.
My power comes from the City of Mesa. Can I get a rebate?
Not from SRP. Its attic rebate is only for SRP residential customers, and some homes near downtown buy power from the city's utility instead. Ask your utility what it offers. Either way, we'll quote the job and show you the R-value you're adding.
Which type should I pick: blown-in, batts or foam?
In an existing attic, blown-in loose-fill can spread across the floor and around wires and joists. Batts belong in open framing, and spray foam goes on roof decks or in unvented attics. For details, see blown-in and batts or open-cell and closed-cell foam.
