Timberline Slate vs Pewter Gray
Two good shingles. One right for you.
When to choose Timberline Slate.
- Your siding is white, cream or sage and you want the roof to lean slightly green rather than flat gray.
- The house sits under tree cover, where a green cast reads as intentional instead of dirty.
- You want a mid gray that still shows granule variation from the street.
- You are matching an existing roof section that already reads green gray.
- You prefer the roof to recede rather than frame the elevation.
When to choose Pewter Gray.
- You want the safest gray in the GAF range, with no color cast to clash with future siding.
- The siding is blue, gray or red brick, where a green cast fights the wall.
- You are selling and want the roof to read neutral to the widest set of buyers.
- You want a slightly darker gray that holds its value under direct Florida sun.
- You are matching trim or hardware that is already cool toned.
