How it shifts
Onyx Black is the asphalt-shingle equivalent of matte black trim. It reads as a single decided line at the top of the house, with no granule shimmer or undertone competing for attention. Architects keep specifying it on contemporary builds for exactly that reason.
The profile
The granule blend is built on a deep carbon base with a faint slate accent that prevents the surface from going dead flat. Up close you can see the dimensional shadow line that gives the Duration profile its premium feel; from the street it reads as one solid color.
Where it belongs
Pairs cleanly with white, off-white, navy, deep green, sage, and warm wood siding. It is the safest color in the catalog if you have not committed to a paint palette yet.

About Onyx Black.
Questions homeowners ask before they commit. Answered without sales spin.
A true deep black with no visible blue, brown, or red undertone. In bright Florida sun it stays black; in shade it reads as pure shadow. The granule blend is a tight mix of carbon and charcoal granules that gives the surface dimensional texture without lifting the perceived color.
Yes, somewhat. A dark asphalt roof can raise attic temperatures by 5 to 15 degrees Fahrenheit at peak summer compared to a light gray. In Florida that translates to roughly 10 to 20 dollars per month in additional cooling cost on a typical 2,500 sq ft home if attic ventilation is adequate. Proper soffit-to-ridge ventilation and a modern radiant barrier under the deck close most of the gap.
Minimally. Owens Corning's ceramic granule coating is engineered to hold color for 25 plus years in Florida UV. Expect a subtle shift toward a slightly warmer tone over the first 5 years, then visual stability. The full warranty covers premature fading.

Across Owens Corning, GAF, CertainTeed, IKO, and Owens Corning, the true-black SKUs read nearly identical in daylight from street distance. The granule blend differs slightly (some have a hint of warm undertone, others stay cooler) but unless you place two roofs side by side most homeowners cannot tell them apart.
It can, but it is less traditional than a terracotta tile look. The black asphalt + cream-stucco combination reads as contemporary Mediterranean rather than historical. If you want the historical look, a multi-tone weathered-wood or warm brown reads closer.
Asphalt shingles in this family typically show their first granule loss (visible as small gritty deposits in gutters) at year 8 to 12. Color stability is excellent over the same window. Most Onyx Black roofs reach year 15 looking visually identical to year 1 unless the house had a serious algae or moss episode.
