Tamlyn Galvanized Roll Flashing — Versatile Water Shed Solution for Roof Junctions
The Tamlyn Galvanized Roll Flashing is engineered for contractors who need a reliable, field-adaptable flashing material for roof junctions and general water management applications. Available in Builder (Bldr), Standard (STD), or 26-gauge galvanized (26 Ga GZD) material, this roll flashing provides improved water shed at critical transition points on the roof. It is also well-suited for jobsite forming of special trim items, making it a versatile addition to any roofing or building envelope package.
Unlike pre-formed flashing that limits jobsite adaptability, roll flashing gives the installer the flexibility to cut and form to precise dimensions on the fly. Painted roll options are also available in standard stock colors — contact for sizing and pricing. This flexibility, combined with the corrosion resistance of galvanized steel, makes the RF1050 a durable and cost-effective choice for professionals managing water intrusion at roof transitions.
Key Features & Benefits
Galvanized Steel Construction
Available in Bldr, STD, or 26 Ga GZD material, the galvanized finish provides corrosion resistance essential for long-term performance at exterior roof junctions. Contractors can specify the gauge that best matches their project requirements and local code compliance needs.
Jobsite Formability
Roll format allows on-site cutting and forming to custom lengths and profiles, eliminating the need to pre-order specific flashing shapes. This reduces material waste and jobsite delays when non-standard trim or transition details are required.
Multiple Width Options
Available in 4", 6", 8", 10", and 12" widths, giving installers the right coverage for a range of roof junction types and water management scenarios. Selecting the appropriate width ensures adequate overlap and water shed at each transition point.
Painted Color Availability
For projects requiring color-matched flashing, painted roll stock is available in standard colors: Almond (AM), Brown (BR), Black (BK), Charcoal (CB), and White (WH). Special order colors are also available — contact Tamlyn for pricing and lead times. This is especially useful for exposed trim applications where aesthetics matter alongside function.
Versatile Application Scope
While primarily designed for roof junction water management, the RF1050 is suitable for many other locations on the roof and can be used to form special trim items on the jobsite. This multi-use capability reduces the number of SKUs a contractor needs to stock for a typical roofing project.
Standard Roll Length for Coverage Efficiency
The 50-foot roll length (RF1050) provides substantial linear coverage per roll, reducing the number of splices and transitions needed during installation. Consistent roll dimensions make estimating material quantities straightforward for project planning.
Common Applications
Roof Junction Water Shedding
The primary application for the RF1050 is forming improved water shed at roof junctions — eaves, rakes, valleys, and wall-to-roof transitions. Properly installed galvanized roll flashing at these points diverts water away from vulnerable penetrations and transitions.
Eave and Drip Edge Flashing
Roll flashing can be cut and formed into drip edge profiles at eaves, providing a cost-effective alternative to pre-formed components when custom dimensions are required or material is already on-site.
Sidewall and Headwall Flashing
At sidewall and headwall intersections where a roof plane meets a vertical wall, roll flashing provides the step flashing or continuous flashing needed to prevent water infiltration behind cladding and into the wall assembly.
Valley Flashing
Cut to width and applied in valleys, galvanized roll flashing handles the concentrated water flow at roof valley intersections, protecting the deck and underlayment from long-term moisture exposure.
Jobsite Trim Forming
Contractors can use roll flashing material in a hand or portable brake to form custom trim profiles on-site, reducing dependency on pre-ordered fabricated pieces when project conditions change.
Chimney and Penetration Flashing
Roll flashing can be cut and shaped for base, counter, and step flashing around chimneys, skylights, and roof penetrations where standard pre-formed pieces do not fit the specific configuration.
General Roof Water Management
Beyond specific junction types, roll flashing is used wherever a continuous galvanized metal barrier is needed to redirect water flow and protect underlying structural components from moisture intrusion.

Frequently Asked Questions
Q: What is the difference between Builder (Bldr), Standard (STD), and 26 Ga GZD material options?
A: Builder grade is typically used for standard residential applications where economy is the priority. STD (Standard) offers consistent quality for both residential and light commercial work. 26 Ga GZD is a heavier-gauge galvanized option that provides increased rigidity and corrosion resistance, suited for more demanding applications or when the flashing will be formed into structural trim profiles.
Q: Can the RF1050 be used for applications other than roofing?
A: Yes. While primarily designed for roof junction water management, the RF1050 is also used for jobsite forming of special trim items and can be applied at many other locations on a building envelope where a formed metal water barrier is needed.
Q: Are painted roll flashing options available in all widths?
A: Painted roll flashing is available — call Tamlyn directly at 1-800-334-1676 for current width availability and pricing, as painted stock options may differ from standard galvanized inventory.
Q: How do I specify a color when ordering painted roll flashing?
A: When ordering painted roll, specify the stock color code: AM for Almond, BR for Brown, BK for Black, CB for Charcoal, or WH for White. Colors outside these standard options are Special Order — contact Tamlyn for availability and lead time.
Q: Can this roll flashing be formed on a standard portable brake?
A: Yes. The galvanized roll flashing is designed to be field-formed using standard hand brakes or portable jobsite brakes, allowing contractors to create custom profiles and trim shapes as needed during installation.
Q: Where can I download the product catalog page for the RF series?
A: The catalog page is available as a PDF download directly from Tamlyn at: https://www.tamlyn.com/PDF/conventional-flashing-catalog-pages/RF.pdf
