Attic insulation in Phoenix, where July highs average 106.5°F.

That 106.5°F figure is the average July high at Sky Harbor. Readings vary across the Valley, but your attic still sits right under a hot roof. If your home is one of the 41.6% in the city built before 1980, its insulation may be thin. We measure first, then quote.

Why the attic

What your attic is up against

Heat from a sunbaked roof works its way down into the rooms below. Insulation slows that flow, and its R-value tells you how well: the higher, the better. Maricopa County sits in IECC climate zone 2B, hot and dry, and ENERGY STAR's attic targets for zone 2 are below.

Blown-in insulation being added to an attic

R49 for a bare attic

An attic with no insulation at all should get R49, per ENERGY STAR's zone 2 guide. That's our target when we find a bare attic.

R38 on top of what's there

Got 3 to 4 inches up there already? ENERGY STAR suggests adding R38 on top. Blown-in loose-fill can add that depth without tearing anything out.

Your options

Three ways to insulate an attic

Blown-in loose-fill tops up an existing attic, batts fit open framing, and spray foam seals the roof deck. Our batt and blown-in page and spray foam page go deeper on each one.

  • Blown-in loose-fill attic top-ups
  • CertainTeed and Owens Corning batts
  • Johns Manville mineral wool batts
  • Open-cell spray foam
  • Closed-cell spray foam
  • Batts for new framing

Local programs

Rebates and programs for Phoenix attics

SRP or APS?

Your address decides which utility serves you, SRP or APS. Only SRP customers can use SRP's rebates, so check your bill first.

SRP's attic rebate

On SRP, a residential customer may qualify to have up to 75% of the cost covered, with a $600 cap. We verified those terms on srpnet.com in October 2026. Rebates can change, so we recheck before you sign.

City weatherization help

Phoenix runs a free Weatherization Assistance Program for income-qualified owners and renters. For a household of four, the income limit is $66,000. Attic insulation and ventilation make its list, along with air sealing and HVAC work.

Historic homes

Willo homes date from 1910 to 1950, and Encanto-Palmcroft homes from 1920 to 1952. Attics that old may hold little insulation, so we measure what's really there.

FAQs: Phoenix Insulation

Attic insulation questions

Which type of insulation should go in my attic?

It depends on the attic. Blown-in loose-fill is the simple way to top up an existing floor. Open-cell foam runs about R-3.6 per inch and closed-cell about R-6, and both seal air leaks. Fiberglass batts, at about R-2.9 to R-3.8 per inch, suit open framing.

I rent. Can I get help with attic insulation?

Possibly. The city's Weatherization Assistance Program serves income-qualified renters as well as owners, and attic insulation is on its list. It's free if you qualify. You apply through the city, and the program is separate from any job we quote.

What should I do before you come out?

Find your attic hatch and clear a path to it. Have a recent power bill handy so we can see your utility. If you know your home's build year, tell us; age hints at what we'll find.

Do you serve every part of the city?

Yes. We take attic jobs in all 15 urban villages, from Maryvale and Encanto to Camelback East, Deer Valley, Desert View and Ahwatukee Foothills. Our office is in Estrella Village.

Do you insulate new homes and commercial buildings too?

Yes. Builders get batts in walls and ceilings, blown-in or foam in the attic, and a detailed bid within 48 hours of sending plans. For commercial spaces, see our commercial insulation page.

Is there an energy code for attic insulation here?

Arizona has no statewide energy code. Instead, each city picks an edition of the IECC and may tweak it, Phoenix included. New work follows the edition the city enforces. For an existing attic, we use ENERGY STAR's zone 2 guidance as the target.
