Find Your Trim Type
Select a trim type below to see geometry explanations, typical dimensions, material options, pricing signals, and a "draw it on Trimgy" guide. Every profile on this list can be drawn and ordered on Trimgy — including non-standard custom profiles not listed here.
Coping Cap
Caps the top of parapet walls and masonry walls to waterproof the wall crown. Mechanically attached to aluminum cleats and lapped at joints to allow thermal movement. Among the highest-value trim pieces on any commercial re-roofing project.
View Coping Cap →Drip Edge / Eave Drip
Directs water off the roof deck and away from the fascia at eaves and rakes. Standard profiles include Type C (L-style), Type D (T-style with positive drip nose), and Type F (wide-face for gutters). Custom profiles handle non-standard fascia heights and color matches.
View Drip Edge →Rake Trim / Gable Trim
Covers the exposed roofing edge at the gable end of a sloped roof, running from eave to ridge. Must be pitched at the correct roof angle to lay flat. Critical for preventing wind-driven rain from entering at the gable edge.
View Rake Trim →Gravel Stop / Roof Edge
Provides a finished edge and a vertical face at the perimeter of flat and low-slope roofs. Retains ballast on BUR and modified bitumen roofs, terminates membrane roofing at the edge, and creates the visual fascia line on commercial buildings.
View Gravel Stop →Counterflashing / Wall Flashing
Caps and seals the top edge of base flashing at walls, chimneys, and parapets. Typically embedded in masonry or inserted into a reglet slot, allowing the base flashing below to move independently with thermal changes.
View Counterflashing →Sidewall Flashing
L-shaped wall-to-roof flashing at the continuous junction of a sloped roof field and a vertical wall — beside parapets, mechanical room walls, and dormers. Fabricated in lapped sections with SMACNA-compliant geometry. Integrates with TPO, EPDM, modified bitumen, and steep-slope panel systems.
View Sidewall Flashing →Valley Flashing
Channels water at roof valleys where two slopes intersect. Open valleys use a visible W-profile or V-channel in metal; valley geometry and width are driven by roof pitch, drainage area, and rainfall intensity per SMACNA.
View Valley Flashing →Fascia Trim / Continuous Fascia
The vertical face trim at the lower eave edge covering rafter ends and the fascia board. Includes a hemmed bottom edge, a hidden back leg under the roofing, and an optional gutter hanger pocket. Common on light commercial and metal-building projects.
View Fascia Trim →Soffit Trim / Soffit Closure
Closes and finishes the underside of the roof overhang between the fascia and the wall. Includes receiver channels, J-channels, and closure panels. Critical for preventing pest entry and providing ventilation in unvented overhang designs.
View Soffit Trim →Jamb Trim / Window Trim
Vertical trim covering the gap between a window or door frame and the wall cladding. On metal buildings, jamb trim must match the wall panel depth. On commercial siding applications, it closes the exposed cut edge and weathers the rough opening.
View Jamb Trim →Lintel Flashing / Sill Pan
Head flashing above openings (lintel) and sill pan flashing at the base of windows and doors prevent water intrusion at the most vulnerable points of the building envelope. Sill pans require end dams — the most commonly missed detail.
View Lintel & Sill Pan →Cap Flashing / Through-Wall Flashing
Through-wall flashing is embedded in masonry walls to intercept and drain water that penetrates the outer wythe. Cap flashing laps the top of base flashing at parapets. Both are critical to masonry building envelope performance.
View Cap Flashing →Z-Flashing / Z-Bar
A Z-shaped profile that diverts water at horizontal transitions in wall cladding — above windows, at changes in cladding type, or at horizontal band boards. Simple geometry but critical placement: a missing Z-flashing is a guaranteed future leak.
View Z-Flashing →Reglet & Counterflashing System
The complete two-piece system used at parapet-to-roof and chimney-to-roof transitions. A reglet (surface-mount or saw-cut into masonry) receives a locked counterflashing. The combined system allows independent movement while maintaining a waterproof lap.
View Reglet System →Base Flashing / Curb Flashing
The primary waterproofing layer at roof-to-wall junctions and around curbs (HVAC equipment, skylights, hatches). Base flashing laps onto the roofing membrane and up the vertical surface, providing the first line of defense before counterflashing.
View Base Flashing →Expansion Joint Cover
Bridges the gap at structural expansion joints in roofs and walls while accommodating thermal movement. Must allow 1"–3" of movement in both directions without leaking. Profiles include bellows, saddle, and slide covers depending on joint width and movement range.

Trimgy's drawing engine is built around one idea: every trim profile is just a series of straight-line segments on a grid. That's true for a simple L-shaped drip edge and it's equally true for a complex 7-leg coping cap. Whatever the profile, the process is the same.
Draw the cross-section
Click point-to-point on a 1/4" precision grid to define each leg of your trim profile. Segment lengths snap to grid increments and display in inches as you draw.
Set material and footage
Choose aluminum thickness (.032", .040", .050", .063") or steel gauge (24 ga, 26 ga) and your required linear footage. Price updates instantly.
