How to Measure a Custom Flashing Profile in Reno
To measure a custom flashing profile, draw the end view and record every leg, bend angle, hem, return, and open edge. State whether each controlling number is an inside or outside dimension. Then add piece lengths, quantities, material, gauge, finish, and the location where the flashing will be used.
How do you draw the end profile?
Imagine cutting across the short direction of the piece and looking at the cut end. Start at one edge and trace the metal through every bend to the other edge. Put a dimension on each straight leg. Mark bends that are not 90 degrees and identify open hems, closed hems, hooks, kick-outs, or returns.
Use arrows that land on the faces being measured. Material thickness and bend radius mean an inside dimension is not interchangeable with an outside dimension. If the part fits over a curb, wall, or another piece, show that mating condition and identify the clearance that matters.
What if the angle is hard to measure?
For roofing trim, provide the verified roof pitch and a section showing where the piece sits. For an existing angled part, an intact physical sample may be more useful than an angle guessed from a phone photo. Label the sample with its location, orientation, and visible face.
Do not copy a crushed or distorted section without noting the damage. If only part of the sample still holds its original shape, mark the reliable area and provide field measurements for the rest.
Which order details go beyond the profile?
The profile controls the cross-section, but the shop also needs finished piece lengths and quantities. Assign a mark to each profile and use that mark on the plan or schedule. Include material type, thickness or gauge, coating, color code, and finish. If the flashing meets a roofing or siding panel, identify the exact manufacturer and profile.

- Plan location and installer approval
Frequently asked questions
Is a cardboard template useful?
It can explain an unusual angle or intersection, but add dimensions and orientation marks. Confirm with the shop whether the template is suitable before relying on it for fabrication.
Can I measure from a photo?
Use photos for context, not final scale. Perspective changes apparent lengths and angles. A direct sketch, verified measurements, or a sound sample is more dependable.
Who should approve the profile?
The contractor or installer responsible for fit and installation should review the field dimensions and approve the final profile before fabrication.
