How it shifts
Stonegate Gray is the kind of gray you choose when you want the roof to recede and the rest of the house to lead. Not quite black, not quite slate. It is a confident, anchored color that absorbs the eye instead of bouncing it. On a south-facing Florida elevation it reads cool and slightly blue. On a north-facing roof in shade it pulls toward true black.
The profile
The granule blend uses a base of charcoal granules with smaller portions of true black and storm-gray accents to keep the surface from going dead flat. In direct midday sun the texture catches enough light to show the dimensional shadow line that gives Belmont its premium feel.
Where it belongs
Works well with crisp white trim, warm wood accents, and natural stone. Slightly cooler than the brown family, so it tends to pair better with blue, sage, and gray sidings than with yellow or peach.

About Stonegate Gray.
Questions homeowners ask before they commit. Answered without sales spin.
A confident, slightly cool dark gray. It reads close to black in shade and as a clean slate in direct sunlight. The granule blend has a faint cool undertone that keeps it from looking flat. On a Florida elevation with strong overhead light, expect the surface to brighten visibly compared to a cloudy day.
Minimally. CertainTeed's ceramic granule coating is engineered to hold color for 25 plus years in Florida UV. Expect a barely-visible shift toward a slightly warmer tone over the first 5 years, then stability. The full warranty covers premature fading.

In direct overhead sun it brightens to a clear charcoal with visible dimensional shadow lines. On cloudy days it reads almost black and recedes visually, which flatters most siding colors underneath. At sunset the granule blend shows its warmth.
Slightly, compared to a white or light-gray roof. In Florida, a mid-dark roof adds approximately 5 to 10 degrees Fahrenheit to attic temperatures during peak summer. Proper attic ventilation and a modern radiant barrier reduce the actual cooling-load impact to less than 20 dollars per month in most homes.
Very similar in daylight. The gray-family SKUs across CertainTeed, GAF, CertainTeed, IKO, and Owens Corning sit within a small tonal window. Subtle differences in granule blend (some lean cool blue, others lean warm slate) become visible only side by side. Use the Compare tab to see direct hex deltas.
Generally yes. CertainTeed's algae-resistance package uses copper- or zinc-infused granules that inhibit the most common Florida algae strain (Gloeocapsa magma). Expect clean performance for the warranty window with normal cleaning; in heavy-shade or low-airflow installations occasional soft-wash maintenance helps.
