Shasta White shingles are an Owens Corning asphalt shingle color, a neutral white with a light gray undertone, made in three shingle families: Supreme (3-tab), Oakridge (laminated) and TruDefinition Duration COOL. Since January 2025 the 3-tab version is made for only one Owens Corning plant service area, centered on Irving, Texas, while the Oakridge and Duration COOL versions keep active Cool Roof Rating Council (CRRC) ratings of 29 to 30 SRI after three years of weathering.
The name causes mix-ups. CRRC also lists “Shasta White” as a painted metal finish from PPG (Duranar ULTRA-Cool, CRRC 0810-0040-018) and Berridge (CRRC 0870-0028), each rated SRI 63. Those are metal panel coatings, not shingles, and every figure on this page refers to the Owens Corning asphalt shingle.
Shasta White shingles: key numbers at a glance
The five facts most buyers search for are which lines carry Shasta White, where the 3-tab is still made, how reflective it is, which California rule it must beat and what a bundle costs. Each row below comes from an Owens Corning data sheet dated 2025 or 2026, the CRRC directory export of October 28, 2026, or a dated supplier listing.

Which Owens Corning lines make Shasta White shingles?
Owens Corning prints Shasta White in three current data sheets: the Supreme 3-tab sheet (Pub. 10013324-P, February 2026), the TruDefinition Duration COOL sheet (Pub. 10021534-O, September 2026) and the COOL Roof Collection sheet (Pub. 10019919-U, August 2026), which also shows Shasta White as an Oakridge color. The standard TruDefinition Duration sheet (Pub. 10024201-E, August 2026) does not show a Shasta White swatch.
The three lines differ far more than the color does. A Supreme shingle is a single-layer 12 x 36 in 3-tab with a 60 mph wind warranty, while Oakridge and Duration COOL are laminated 13-1/4 x 39-3/8 in shingles with 110 mph or higher wind warranties, per the spec tables on the Supreme, Oakridge and Duration COOL product pages.
| Spec | Supreme (3-tab) | Oakridge (laminated) | TruDefinition Duration COOL | Source |
|---|---|---|---|---|
| Size and exposure | 12 x 36 in, 5 in exposure | 13-1/4 x 39-3/8 in, 5-5/8 in | 13-1/4 x 39-3/8 in, 5-5/8 in | OC data sheets |

Is Shasta White discontinued? Status by line and region
Shasta White is not discontinued everywhere, but each version has shrunk. An Owens Corning letter dated January 15, 2025 ended Supreme sales in seven plant service areas (Brookville IN, Denver CO, Kearny NJ, Medina OH, Minneapolis MN, Portland OR and Summit IL) and left Shasta White only in the Irving, TX column of the five remaining areas. The supplier Mueller posts a copy of that letter.
The February 2026 Supreme data sheet matches the letter: its color chart marks Shasta White only in service area 10, which the sheet’s map draws over Texas, Oklahoma and New Mexico. Onyx Black, Estate Gray, Driftwood and Desert Tan are marked in all five areas (2, 3, 6, 8 and 10). For the standard Duration line, the Rhode Island contractor Seaberg Construction reported in 2023 that Shasta White was one of four Duration colors cut, alongside Amber, Quarry Gray and Desert Tan.
| Version | Status found October 2026 | Evidence |
|---|---|---|
| Supreme 3-tab Shasta White | Made for service area 10 (Irving, TX) only | OC letter Jan 15, 2025; Supreme sheet Feb 2026; CRRC 0890-0044 “Supreme Shasta White IRV” |
| Supreme at Home Depot (model SA12, Internet #205655950; AR model PM12, #205655940) | Both listings read “currently unavailable” in Google’s index | Home Depot listing text, Oct 29, 2026 |
| Oakridge Shasta White | Active CRRC rating; listed as an Oakridge color in the Aug 2026 COOL Roof Collection sheet; regional | CRRC 0890-0002; Pub. 10019919-U |
| TruDefinition Duration COOL Shasta White | Active; shown on the Sept 2026 Duration COOL sheet | CRRC 0890-0008; Pub. 10021534-O |
| Standard TruDefinition Duration (AR) Shasta White | Dropped from the Duration palette (cut reported 2023); no swatch on the Aug 2026 sheet; one supplier still listed AR bundles in Oct 2026 | Seaberg Construction 2023; Pub. 10024201-E; McCoy’s listing Oct 2026 |
Owens Corning’s product pages filter colors by ZIP code, and its shingle selector asks for a location before it shows a palette. A supplier in Dallas may stock all three versions while one in Denver stocks none, so ask the yard for the plant code printed on the bundle wrapper before you plan a roof around this color.
What color is Shasta White?
Owens Corning describes Shasta White as a “neutral white shingle with a light gray undertone” in its shingle poster store, which sells a printed Shasta White color poster for $16.95 (SKU 10020288, as listed October 2026). The distributor Cameron Ashley files the Duration version under the color family “Light Gray.”
CRRC’s color field splits the same way. The Oakridge, Duration COOL and Supreme/Classic listings are tagged “Bright White,” while the Irving-made Supreme listing (0890-0044) is tagged “Off-White, Gray.” The Asphalt Roofing Manufacturers Association (ARMA) notes that algae discoloration is most readily visible on light-colored roofs, so a white-and-gray blend like this one shows streaks sooner than Onyx Black or Driftwood.
The pairings below are editorial suggestions, not Owens Corning recommendations. Order a physical sample, since Owens Corning’s own color disclaimer says printed swatches vary and advises viewing an installed roof.
| House palette | How Shasta White reads against it | Editorial note |
|---|---|---|
| Navy, black or charcoal siding | Strong contrast; roof reads pale gray | White trim blends into the roof edge; black gutters frame it |
| White or cream siding | Low contrast; roof can look washed out | Darker fascia or gutters separate roof from walls |
| Red or brown brick | Warm brick against a cool gray-white | Gray mortar ties the two together better than tan mortar |
| Coastal blue or sage siding | Light, beach-cottage look | Shows algae fastest in humid coastal air; pick an AR version |
How reflective is Shasta White? CRRC ratings and Title 24
Shasta White reflects 25% to 28% of sunlight when new and 28% to 29% after three years outdoors, per the CRRC rated product export of October 28, 2026. The aged values sit above the initial ones, so the color holds its rating as it weathers. Owens Corning’s August 2026 COOL Roof Collection sheet prints the same aged SR and SRI for Oakridge (0.28, SRI 30) and Duration COOL (0.29, SRI 29).
| CRRC ID | Listed product | Initial SR | 3-yr SR | Initial / 3-yr emittance | Initial / 3-yr SRI |
|---|---|---|---|---|---|
| 0890-0001 | Classic Shasta White (alias Supreme) | 0.27 | 0.29 | 0.89 / 0.92 | 27 / 32 |
| 0890-0002 | Oakridge Shasta White | 0.26 | 0.28 | 0.90 / 0.91 | 27 / 30 |
| 0890-0008 | TruDefinition Duration Cool Shasta White (alias TruDefinition Duration) | 0.25 | 0.29 | 0.94 / 0.87 | 27 / 29 |
| 0890-0044 | Supreme Shasta White, IRV (Irving plant) | 0.28 | Not yet listed | 0.92 / not yet listed | 30 / not yet listed |
Source: CRRC Rated Products Directory daily export, October 28, 2026. Under California Energy Code Section 110.8(i), Exception 1, an asphalt shingle without a CRRC rating must assume an aged SR of 0.08 and emittance of 0.75, so the rating itself is what earns compliance.
Every rated Shasta White listing clears California’s steep-slope cool roof minimums. The CRRC chart of the 2025 Energy Code (effective January 1, 2026) sets the thresholds in the table below.
| Rule | Where it applies | Aged SR / emittance / SRI minimum | Shasta White (Oakridge 0.28 / SRI 30) |
|---|---|---|---|
| 150.2(b)1Ii, single-family re-roof, steep slope | Climate zones 4 and 8 to 15 | 0.20 / 0.75 / 16 | Passes |
| 150.1(c)11A, single-family new construction, steep slope | Climate zones 10 to 15 | 0.20 / 0.75 / 16 | Passes |
| 170.2(a)1A, multifamily new construction, steep slope | Zones 10, 11, 13 and 15 (stricter row) | 0.25 / 0.75 / 23 | Passes |
| LA County Green Building Standards Code and LA City Cool Roofs Ordinance | Los Angeles County and City | Aged SRI 20, per Owens Corning’s COOL sheet | Passes |
| Section 10-113 labeling | Any California job claiming cool roof compliance | Product label must show CRRC-rated values | Check the wrapper; the IRV Supreme listing had no aged value yet |
ENERGY STAR no longer certifies roofs. The program for roofing products ended June 1, 2022, according to CRRC and the ENERGY STAR roof products page, so an older brochure line saying Shasta White “meets ENERGY STAR” describes a program that has ended. The federal 25C home improvement credit, which stopped covering asphalt roofs after 2022, ended for property placed in service after December 31, 2025 under Public Law 119-21.
Our solar reflective shingles explainer compares SR, emittance and SRI across every brand’s cool line.
Shasta White vs other makers’ white shingles
Four other manufacturers list a white asphalt shingle in the October 28, 2026 CRRC export with a higher 3-year SRI than Oakridge Shasta White’s 30: TAMKO Heritage Premium Glacier White (34), Malarkey Dura-Seal Dove White (33), IKO Cambridge Super White (32) and Malarkey Highlander AR Dove White (31). No GAF asphalt shingle with “white” in its name appears in that export.
| Maker and color | Line(s) named in CRRC | CRRC ID | 3-yr SR | 3-yr SRI | Maker page |
|---|---|---|---|---|---|
| Owens Corning Shasta White | Oakridge | 0890-0002 | 0.28 | 30 | Owens Corning |
| TAMKO Glacier White | Heritage Premium (aliases Heritage, Heritage Woodgate, Heritage Vintage) | 0714-0037 | 0.32 | 34 | TAMKO Glacier White |
| TAMKO Glacier White | Elite Glass-Seal, Titan XT, StormFighter Flex | 0714-0040 | Initial 0.24 only | Initial 25 only | TAMKO |
| Malarkey Dove White | Dura-Seal | 0850-0013 | 0.28 | 33 | Malarkey Highlander |
| IKO Cambridge Super White | Cambridge (alias Marathon Ultra AR) | 1214-0001 | 0.29 | 32 | IKO Cambridge |
| Malarkey Dove White | Highlander AR | 0850-0022 | 0.27 | 31 | Malarkey |
| CertainTeed Mist White | Landmark Solaris | 0668-0071 | 0.28 | 29 | CertainTeed Landmark Solaris |
| CertainTeed Silver Birch | Landmark, Landmark PRO, NorthGate, Landmark Solaris, ClimateFlex | 0668-0072 | 0.27 | 27 | CertainTeed |
A CRRC listing proves a rating, not stock: the directory export carries a note that it is generated once per day and may differ from the live directory, and Malarkey’s Highlander page shows colors by location. The broader question of whether true bright-white asphalt shingles still exist is covered on our white roof shingles page.
Shasta White shingles price at Home Depot, Lowe’s and suppliers
Shasta White bundles listed between $34.99 and $56.99 in Google Shopping on October 28 and 29, 2026, depending on the line and on whether the bundle is the algae-resistant (AR) or COOL (non-AR) version.

Worked example: what a Shasta White roof costs
A 2,000 sq ft roof (20 squares) with a 10% waste allowance needs 22 squares of Shasta White, which is 66 bundles in any of the three lines. Shingles alone run about $2,309 in Supreme to $3,761 in Duration COOL at the October 2026 listed prices. This is a Roofing Brief estimate with the arithmetic shown.
| Step | Supreme ($34.99) | Duration AR ($46.99) | Oakridge Cool Non-AR ($47.99) | Duration COOL Non-AR ($56.99) |
|---|---|---|---|---|
| Roof area | 2,000 sq ft = 20 squares | |||
| Add 10% waste | 22 squares | |||
| Bundles (3 per square) | 66 bundles | |||
| Shingle material | 66 x $34.99 = $2,309.34 | 66 x $46.99 = $3,101.34 | 66 x $47.99 = $3,167.34 | 66 x $56.99 = $3,761.34 |
| Installed range, site baseline | $4 to $6/sq ft (3-tab) = $8,000 to $12,000 | $5 to $8/sq ft (architectural) = $10,000 to $16,000 | ||
The installed ranges apply the per square foot baselines in our 2026 roofing cost report to 2,000 sq ft. The color carries no published premium of its own; the line does, with a $13 gap per bundle between Supreme ($34.99) and Oakridge Cool ($47.99) in the listings above. Owens Corning’s 25-year Oakridge algae warranty also requires an Owens Corning Hip & Ridge product, so price the Shasta White ridge cap too. Our bundle estimating guide covers hips, valleys and starter counts.
Where white shingles stain, and how the AR and COOL versions differ
ARMA names Gloeocapsa magma as probably the most prevalent algae behind roof discoloration and says it is most widespread in the Gulf States and along the Northwest and Eastern Seaboards. On a white-and-gray shingle the brown-to-black streaks show years before they would on Onyx Black.
That makes the AR versus COOL split the biggest decision within Shasta White. Arbor’s October 2026 listings sell Oakridge Cool and Duration Cool Shasta White as “Non-AR,” and the Duration COOL data sheet lists no algae warranty, while the standard Oakridge sheet lists a 25-year StreakGuard algae warranty and Supreme a 10-year one offered regionally. The COOL version buys Title 24 paperwork; the AR version buys streak coverage.
| Stain on a Shasta White roof | Where it shows first | What to do |
|---|---|---|
| Algae (Gloeocapsa magma) | Shaded and north-facing slopes, below ridges | ARMA: household bleach and water, dwell at least 15 and no more than 20 minutes, gentle water rinse; avoid scrubbing, which loosens granules |
| Moss and lichen | Under overhanging trees, low-pitch areas | ARMA says to ask the shingle maker for moss removal advice; trim branches that shade the slope |
| Rust streaks | Below steel flashing, vents and dish mounts | Replace or coat the corroding part; bleach will not remove iron oxide |
| Granule loss | Valleys and drip lines under upper gutters | Dark asphalt shows through white granules; compare against the warranty’s granule terms |
ARMA says bleach cleaning is temporary and the discoloration may recur. Our asphalt shingle cleaning guide gives the mix ratios and safety steps, and algae streaks on roofs covers prevention.
How to match Shasta White for a repair
A repair on an older Shasta White 3-tab roof is the hardest case, because Supreme Shasta White has been made only for the Irving, TX service area since January 2025. New granules also look brighter than a 10-year-old roof in the same color, so expect some contrast on any patch larger than a few tabs.
- Identify the line. Measure one shingle: 12 x 36 in with three tabs and a 5 in exposure is Supreme or the older Classic; 13-1/4 x 39-3/8 in laminated with a 5-5/8 in exposure is Oakridge or Duration. A woven fabric strip at the nail line means Duration (SureNail).
- Check the attic or garage for leftover bundles. Wrappers carry the plant and lot code, and the Supreme installation instructions warn against mixing shingles from different lot numbers.
- Call a service area 10 supplier. Yards in Texas, Oklahoma or New Mexico, such as MG Building Materials at $34.99 a bundle (October 2026), may ship 3-tab Shasta White.
- Ask for the IRV production. CRRC lists the Irving-made Supreme Shasta White as 0890-0044, so bundles carrying that rating are the current production run.
- Consider another maker’s white 3-tab. CRRC lists Glacier White under TAMKO’s Elite Glass-Seal and Dove White under Malarkey’s Dura-Seal; confirm the size, because a 36 in shingle will not course with a 39-3/8 in metric shingle.
- Move matched shingles to the front. Pull weathered Shasta White from a rear slope for the visible repair and put the new bundles at the back.
- Nail to code. Section R905.2.6 of the 2021 IRC requires at least four fasteners per strip shingle, or the maker’s count where it is higher; Oakridge needs six nails plus Owens Corning starter for its 130 mph wind warranty.
When damage spans whole slopes rather than a few tabs, our shingle replacement guide sets repair versus re-roof thresholds, and the 3-tab shingles guide lists which makers still sell 3-tab lines.
Which Shasta White shingle should you pick?
The version to buy turns on two facts about the house: whether a California-style cool roof rule applies, and whether the roof sits in humid or shaded conditions where algae grows. The table maps each case to a product using the data sheet and CRRC values above.
| If your situation is | Pick | Why |
|---|---|---|
| California re-roof in climate zones 4 or 8 to 15 | Duration COOL or Oakridge Shasta White with the CRRC label on the bundle | Aged SR 0.28 to 0.29 beats the 0.20 minimum in 150.2(b)1Ii |
| Humid Gulf or Southeast lot, or a shaded north slope | Oakridge AR (HL12) Shasta White | 25-year StreakGuard algae warranty; the COOL sheet lists none |
| Hail-prone area wanting an insurance discount | Duration COOL Shasta White (Class 3), or a Class 4 shingle in another color | Oakridge lists no impact class; Duration COOL is UL 2218 and FM 4473 Class 3 |
| Patching an existing white 3-tab roof | Supreme Shasta White from a service area 10 supplier | Only remaining 3-tab Shasta White production (Irving, TX) |
| High-wind area needing 130 mph or more | Oakridge with 6 nails and OC starter, or Duration COOL with OC components | The 130 mph and 160 mph warranties require those components |
| You want the most reflective white asphalt shingle | Compare TAMKO Heritage Premium Glacier White (SRI 34) and Malarkey Dura-Seal Dove White (SRI 33) | Both rate above Shasta White’s 29 to 30 in CRRC |
| Outside service area 10 and set on a 3-tab | Another Supreme color or another maker’s white 3-tab | Supreme Shasta White is not made for your plant area |

Frequently asked questions
Is Shasta White discontinued?
Not everywhere. Owens Corning ended Supreme 3-tab sales in seven plant service areas on January 15, 2025 and kept Supreme Shasta White only in the Irving, Texas area. Oakridge and TruDefinition Duration COOL Shasta White still appear in Owens Corning’s August and September 2026 data sheets, though availability depends on ZIP code. The standard Duration palette dropped Shasta White, with the cut reported in 2023.
Does Home Depot sell Shasta White shingles?
Home Depot lists Oakridge Shasta White (model HK12, Internet #205655928) and Oakridge AR Shasta White (HL12, #205655918) at 32.8 sq ft per bundle. Its Supreme 3-tab listings, SA12 and PM12, showed as currently unavailable in October 2026. Stock varies by store, so check the model number in the app before driving over.
Is Shasta White a cool roof shingle?
Yes, for the rated versions. CRRC lists Oakridge Shasta White (0890-0002) at an aged solar reflectance of 0.28 and SRI 30, and Duration COOL Shasta White (0890-0008) at 0.29 and SRI 29. Both beat California’s steep-slope re-roof minimum of 0.20 aged reflectance or SRI 16 under Energy Code section 150.2(b)1Ii in climate zones 4 and 8 to 15.
Can you still buy white roof shingles?
Yes. Besides Owens Corning Shasta White, the October 28, 2026 CRRC export lists TAMKO Glacier White, Malarkey Dove White, IKO Cambridge Super White and CertainTeed Landmark Solaris Mist White, with 3-year SRI values from 29 to 34. A CRRC listing shows a rating, not local stock, so confirm with a supplier in your area.
Did Owens Corning discontinue 3-tab shingles?
Only in part. The January 15, 2025 Owens Corning letter stopped Supreme sales in Brookville IN, Denver, Kearny NJ, Medina OH, Minneapolis, Portland OR and Summit IL service areas. Supreme stayed in five areas, with Onyx Black, Estate Gray, Driftwood and Desert Tan in all five and Shasta White in Irving, Texas only.
What warranty comes with Shasta White shingles?
It depends on the line. Supreme carries a 25-year limited warranty, a 60 mph wind warranty and a regional 10-year algae warranty. Oakridge carries a Limited Lifetime warranty, 110 mph wind (130 mph with 6 nails and OC starter) and a 25-year algae warranty. Duration COOL carries a Limited Lifetime warranty and up to 160 mph wind, with no algae warranty listed.
Do Shasta White shingles show algae stains?
They show them sooner than dark colors. ARMA says algae discoloration is most visible on light-colored roofs and most widespread in the Gulf States and along the Northwest and Eastern Seaboards. If you build in those regions, choose an AR version such as Oakridge AR (HL12), which carries a 25-year StreakGuard algae warranty that requires an Owens Corning Hip and Ridge product.
