Chimney Chase Cover Measurements for Truckee Homes
For a custom chimney chase cover, measure the outside chase width and depth in several places, locate every flue, record each flue's outside size and height, and document the siding, trim, and mounting edge. Add clear photos from multiple angles. The installer should verify all roof measurements before fabrication.
What exactly are you measuring?
A chase cover spans the framed chimney chase and turns down over its top edge. It is not the same as a small cap that attaches directly to one flue. Before requesting a quote, identify whether you need a full chase cover, a flue cap, or an assembly that includes both types of components.
Measure the outside width and depth at the top of the finished chase. Take each dimension near both ends rather than assuming the chase is square. Record the two diagonal measurements as a check. If they differ, the top is out of square and the fabricator needs to know before the cover is formed.
How should flues be located?
Every pipe or flue passing through the cover needs an opening in the right place. Draw a top view of the chase. Choose one finished corner as the reference, then dimension to the centerline of each flue in both directions. Record the outside diameter or outside width, not an estimated nominal size.
Measure how far each flue extends above the chase and note any storm collar, listed chimney component, or existing cap. Clear photos help identify the arrangement, but the chimney professional should confirm required openings, separations, clearances, and listed-system details. Fabrication dimensions do not establish code compliance.
Why do slope and edges matter in Truckee?
A chase cover should not be treated as a flat tray with holes. The top geometry, raised areas around penetrations, seams, and perimeter edges all affect how water and snowmelt leave the surface. Truckee homes also need project-specific review for snow exposure and roof access. The appropriate contractor or design professional should determine the required assembly for that building.
Document whether the cover turns down over wood, siding, stucco, stone, or existing metal trim. Measure the available vertical edge and show where fasteners can attach without interfering with other finishes. Note nearby roof slopes, crickets, walls, and anything that limits installation access.
What material and appearance details belong in the request?
State the preferred material and finish if the exterior design already sets them. The shop fabricates custom chimney work in copper, stainless, and galvanized metal. Include roof and trim colors when a visible finish needs to coordinate. If appearance matters from a particular side of the home, mark that side on the drawing.
Pro Form Metals fabricates in Reno for Truckee projects. Review the custom chimney caps service page, the Truckee service area page, and the Sierra chimney cap guide for additional planning context.

Frequently asked questions
Can ground-level photos replace roof measurements?
No. They can help start a discussion, but perspective hides exact size and location. A qualified person with safe roof access should verify the dimensions.
How much should the cover overhang?
That depends on the chase finish, edge detail, and mounting plan. Show the existing construction and have the fabricator and installer agree on the finished dimensions.
Who confirms chimney clearances and code requirements?
The chimney professional, contractor, and applicable project authority should confirm them. A fabricated cover must follow the approved system details.
