Best roof forEl Paso heat
The best roof for El Paso heat is a light-colored, cool-rated surface that reflects sun and sheds the heat it absorbs, such as a white roof coating or cool-pigment painted metal. A dark roof can reach 150 F or more in summer sun, and a cool roof can stay more than 50 F cooler.1
Reflect the sun,shed the heat
A cool roof does two jobs, and El Paso needs both. El Paso sees 116.8 days a year at 90 F or more, so a roof spends months absorbing sun.2
Solar reflectance is the share of the sun's energy a roof bounces back, on a scale of 0 to 1. Thermal emittance is how well the roof gives off the heat it did absorb. The Solar Reflectance Index (SRI) combines the two, with standard black at 0 and standard white at 100.3
The material alone doesn't settle it. The Cool Roof Rating Council (CRRC) says SRI values can vary greatly within one material type, and its three-year ranges overlap.3
| Material | 3-year SRI range | What decides where one lands |
|---|---|---|
| Clay and concrete tile | 4 to 91 | The color and surface of the tile |
| Asphalt shingles | 14 to 34 | Cool-color granules versus standard ones |
| Factory-coated metal | 20 to 90 | The paint and its pigments |

Rule of thumb. Pick by the rated number for the exact product and color, not by the material's name.
Shingles, metal,and coatings
Shingles gain a little
Cool-color shingles are a modest step up, not a white roof. Asphalt shingles start at a solar reflectance of 0.20 to 0.30, or SRI 16 to 32 when new.4 IKO says its Cambridge Cool Colors Plus line has an SRI of 20 or greater, and sells it only in select U.S. markets.5
Metal depends on the finish
Bare Galvalume reflects well but gives heat back poorly, because its thermal emittance is very low. Painted metal with cool pigments can reach an emittance of 0.90.1 A lighter painted finish on metal roofing is the one to look for.
White coatings reflect most, then fade
Liquid coatings on low-slope roofs rate the highest of any type, from SRI 71 to 114 new.4 White coatings lose ground quickly, though. A reflectance of 0.85 to 0.90 drops to 0.60 to 0.70 after the first year, a loss of 25 to 30 percent.6
Dirt drives much of that loss, so aged ratings matter more than new ones. Recoating on schedule is normal upkeep that the owner pays for, and the lifetime warranty from Lifetime Roofing covers our workmanship.
Check the ratingbefore you buy
The CRRC Rated Products Directory lists each product's initial and aged reflectance and emittance. Look up the aged numbers, since CRRC tests products new and again after three years outdoors.3
Cool roofs also don't replace insulation, and their benefit inside the house varies. The EPA says that in homes with air conditioning, cool roofs can cut peak cooling demand by 11 to 27 percent. In homes without it, they can lower the top indoor temperature by 2.2 to 5.9 F.7
If your house runs a swamp cooler, the roof matters for another reason, because the cooler's base is a leak point. The swamp cooler roof leaks guide covers that.
A light roof color can also need approval in a historic district. The historic district roofing guide explains the review.

El Paso Electric'scool roof incentive
As of November 1, 2026, El Paso Electric lists a cool roof incentive of up to $0.06 a square foot, about $120 on a 2,000 square foot roof. The program guidelines say it runs through December 31, 2026, or until funding runs out.8
The limits are real. The home must be a single-family home of one to four units that gets El Paso Electric service, and the existing roof must be a standard medium or dark color.8
- The product must be CRRC-rated: initial reflectance 0.65 and three-year 0.50 on a low-slope roof, or 0.25 and 0.15 on a steeper one.8
- Only coatings over conditioned space count, so areas over garages and porches are out.9
- Paperwork is due within 45 days of the invoice date, with before and after roof photos and a copy of the invoice.8
- The amount depends on insulation, slope, product rating, and roof size, and terms can change without notice.8
El Paso Electric's pages disagree on which cooling systems qualify. One page allows evaporative cooling, and the income-qualified page lists only refrigerated air.9 Call CLEAResult at (915) 255-4300 before you buy.
Lifetime Roofing doesn't claim that any roof it installs qualifies. Check the product's CRRC rating against the numbers above, and ask the program first.
Questions people askabout roofs and heat
Do cool shingles work in El Paso?
A little. Cool-color shingles reflect more than standard ones, but asphalt rates only SRI 16 to 32 new. Lifetime Roofing installs IKO shingles, and IKO sells its Cool Colors Plus line, SRI 20 or greater, in select U.S. markets only.
Is a metal roof a cool roof?
Only with the right finish. Bare Galvalume gives heat back poorly, while painted metal with cool pigments can reach an emittance of 0.90. Lifetime Roofing installs metal roofing, and the finish decides how it performs.
Do white roof coatings stay white?
Not fully. A white coating loses 25 to 30 percent of its reflectance in the first year. Recoating on schedule is normal upkeep, and the owner pays for it. Lifetime Roofing's warranty covers our workmanship.
Does El Paso Electric pay for a cool roof?
Up to $0.06 a square foot. The program runs through December 31, 2026, or until funds run out, with limits on home, roof color, and product rating. Call CLEAResult at (915) 255-4300. Lifetime Roofing claims no product qualifies.
