Custom Sheet Metal Fabrication for Roofing & Exterior Details
Properly fabricated flashing, trim, panels, and transitions are some of the most important details on a roofing system. Ja-Mar Roofing & Sheet Metal supports residential and commercial roofing projects with custom sheet metal fabricated through our in-house facility in Central Texas.
Our sheet metal capabilities allow us to build project-specific pieces rather than relying only on off-the-shelf components. That becomes especially useful on complex roofs, standing seam systems, specialty flashing, architectural details, commercial properties, and buildings where standard trim simply does not fit the conditions.
Why In-House Sheet Metal Fabrication Matters
Roofing and exterior metal work often comes down to details that must fit the building in front of you. Having fabrication capabilities in-house gives our team more flexibility when a project calls for custom dimensions, unusual transitions, specialty metals, or details that need to coordinate with the roof and wall systems.
Custom Sheet Metal for Roofing & Architectural Applications
Ja-Mar’s fabrication work supports both residential and commercial roofing projects. The exact metal, profile, dimensions, attachment, and finish depend on the building and application.
Standing Seam Roof Panels
Metal coil can be formed into standing seam roofing panels in project-specific profiles. Panels, clips, flashings, and trim must work together as a complete roof system rather than as isolated pieces.
Roof Flashing
Custom flashing helps manage water where roofs meet walls, chimneys, curbs, penetrations, valleys, edges, and other transitions. These details are often among the most important parts of a watertight roof assembly.
Chimney Caps
A properly designed chimney cap can help reduce rain and animal entry while allowing the chimney to vent as intended. The appropriate cap depends on the chimney, flue, dimensions, and project requirements.
Custom Trim & Architectural Metal
Our sheet metal work can include copings, fascia, edge metal, transitions, wall details, custom trim, and other fabricated components needed to finish roofing and exterior metal projects.
Standing Seam Metal Roofing Fabricated for the Project
Ja-Mar Roofing & Sheet Metal has extensive experience with mechanically seamed and other standing seam metal roofing systems used throughout Central Texas. These systems use formed metal panels with raised seams and concealed attachment points to create a clean architectural roof surface.
Panel profile, seam height, clip design, substrate, roof slope, wind exposure, panel length, finish, and flashing details can vary from one system to another. Our fabrication capability allows the roofing and sheet metal portions of the project to be planned together.

Chimney Caps & Custom Roof Flashing
Chimney Caps
Chimney caps sit over the top of a chimney or flue assembly and can help limit rain, debris, and animal entry while preserving proper exhaust flow. Some designs may also incorporate spark-arresting features when required for the specific chimney system.
Because chimneys vary in shape, size, flue arrangement, masonry condition, and roof geometry, custom fabrication can be useful when an off-the-shelf cap does not fit the structure well.
Flashing
Flashing is formed material installed at roof transitions and openings to direct water away from vulnerable areas. It is commonly used around chimneys, walls, valleys, penetrations, curbs, edges, and places where different roof or exterior materials meet.
Good flashing is not just about the metal itself. Shape, laps, integration with underlayment, sealant placement, attachment, drainage, and the surrounding roof system all affect how well the detail performs.

Custom Sheet Metal Fabrication FAQs
Answers to common questions about custom roof flashing, chimney caps, standing seam panels, architectural metal, and in-house fabrication.
What roofing components can be custom fabricated from sheet metal?
Depending on the project, custom sheet metal can include standing seam roof panels, flashing, trim, copings, edge metal, chimney caps, transitions, fascia, roof-to-wall details, and other fabricated pieces needed to complete the roof or exterior system.
Why use custom flashing instead of standard off-the-shelf pieces?
Standard flashing works well when the dimensions and detail match the product. Custom fabrication becomes useful when a roof has unusual geometry, nonstandard dimensions, specialty materials, complex transitions, or an architectural detail that needs to fit the building more precisely.
Does Ja-Mar fabricate standing seam metal roof panels?
Yes. Ja-Mar Roofing & Sheet Metal has in-house panel-forming and sheet metal fabrication capabilities that support standing seam metal roofing projects. The panel profile and system details depend on the project requirements.
Can custom sheet metal be used on commercial buildings?
Yes. Custom sheet metal is commonly used on commercial roofing projects for copings, flashing, edge metal, penetrations, roof-to-wall transitions, standing seam systems, architectural features, and other project-specific details.
Can Ja-Mar fabricate copper roofing and flashing details?
Yes. Copper can be used for certain custom flashing, chimney, architectural, and roofing details when it is appropriate for the project design and surrounding materials.
Have a Roofing Project That Needs Custom Sheet Metal?
Ja-Mar Roofing & Sheet Metal can evaluate the roof or exterior detail, determine what needs to be fabricated, and coordinate custom sheet metal with the rest of the project.
