Tamlyn FS Series Steel Step Shingles — Pre-Cut Flashing for Chimneys and Skylights
The Tamlyn FS series Steel Step Shingles are multi-purpose metal flashing components designed for use in chimney flashing, skylight flashing, and a range of other step-flashing applications. Engineered for roofing and construction professionals, these step shingles eliminate the time-consuming task of cutting standard 10-foot flashing pieces down to shorter, usable lengths on the job site. They are furnished in pre-cut, user-friendly pieces that are ready to install directly from the bundle, supporting faster project completion and reduced material waste.
Unlike standard long-length flashing stock that requires field cutting, the Tamlyn FS step shingles arrive pre-cut to specified dimensions, saving valuable labor time and reducing the risk of inconsistent cuts. Manufactured in 32-gauge galvanized steel, with factory-painted color options available as special orders, these shingles offer the flexibility to match project specifications without special fabrication work on site.
Key Features & Benefits
Pre-Cut for Job-Site Efficiency
Each piece is pre-cut to the specified length, eliminating the need to cut 10-foot flashing rolls or strips in the field. This reduces labor time, minimizes measurement errors, and keeps projects on schedule.
32-Gauge Galvanized Steel
All FS step shingles are manufactured in 32-gauge galvanized steel, providing the corrosion resistance needed for concealed step-flashing details while remaining easy to bend and weave with roofing courses in the field.
Factory-Painted Color Options
For painted applications, stock colors include Almond (AM), Brown (BR), Black (BK), Charcoal (CB), and White (WH). This allows visible flashing installations to blend with roofing and exterior finishes without requiring field painting or custom fabrication.
Sold in Bundles of 100 Pieces
The listed price is per 100-piece bundle, not per individual shingle. Bundled in quantities of 100 pieces, these step shingles are packaged for commercial and production-scale roofing work. Bulk packaging reduces per-unit cost and simplifies inventory management on multi-unit or large-scale projects.
Special Order Sizing Available
Beyond the standard stocked sizes (FS447, FS448, FS4410, FS557, FS6610, FS6612), other dimensions can be ordered as special order items. This makes the FS series adaptable to non-standard flashing details without requiring custom shop fabrication.
User-Friendly Handling
The step shingle form factor is designed for ease of handling and installation, allowing installers to work efficiently on roof slopes and around penetrations without awkward manipulation of long flashing strips.
Common Applications
Chimney Flashing
Step shingles are a standard component of chimney flashing systems, integrating with counter flashing to create a watertight seal at the intersection of the chimney and roof plane. The pre-cut format simplifies installation in this high-detail area.
Skylight Flashing
The FS series is explicitly designed for skylight flashing applications, where consistent step dimensions are critical to achieving proper water management around the skylight curb and adjacent roofing courses.
Roof-to-Wall Step Flashing
Wherever a sloped roof plane meets a vertical wall — such as at dormers, additions, or adjacent wall cladding — step shingles provide the repeating flashing layer integrated between each shingle course to prevent water infiltration.
Penetration Flashing Details
Step shingles can be adapted to other roof penetrations where a stepped flashing approach is required, providing a versatile solution for multiple flashing conditions on the same roof.
New Construction Roofing
On new construction projects, pre-cut step shingles allow roofing crews to maintain production pace by eliminating field cutting during initial installation.
Re-Roofing and Replacement Flashing
When replacing deteriorated flashing on existing structures, the standardized pre-cut sizes match common roofing dimensions, allowing for direct replacement without custom cutting.

Frequently Asked Questions
Q: Are these step shingles sold individually or in bulk?
A: They are sold in bundles of 100 pieces. Individual piece sales are not offered for standard stock sizes.
Q: What material grades are available, and how do I choose?
A: All FS step shingles are 32-gauge galvanized steel, which balances easy field forming with the corrosion resistance needed for concealed step-flashing details.
Q: Can I order custom sizes not shown in the standard lineup?
A: Yes. Tamlyn offers other sizes as special order items. Contact Tamlyn at 1-800-334-1676 to request non-standard dimensions.
Q: How do I specify a painted finish when ordering?
A: Append the color code to the item ID when ordering. Stock painted colors are: AM (Almond), BR (Brown), BK (Black), CB (Charcoil), WH (White). Colors outside these five are considered special order and will have extended lead times.
Q: What is the advantage of pre-cut step shingles over cutting from 10-foot flashing stock?
A: Pre-cut pieces eliminate field measuring and cutting, reducing labor time and the risk of inconsistent dimensions. On large roofing jobs with many flashing courses, this translates to meaningful time savings and more uniform installation quality.
Q: Are these compatible with both new construction and re-roofing applications?
A: Yes. The standardized dimensions of the FS series make them suitable for both new construction and replacement flashing on existing structures where standard shingle exposures are used.
