K&M Sheet Metal manufactures custom metal chimney caps, chase covers, chimney pots and decorative shrouds for homeowners and contractors. Choose an established design in the size your project requires, or send us drawings for a custom fabrication review.
Our range includes copper and stainless steel, along with Kynar-finished aluminum and steel in colors. From a simple multi-flue cap to an ornamental Crown or Royal design, the right selection brings together appearance, weather protection, fit and access for maintenance.
A chimney cap, chase cover, pot and shroud are not interchangeable. Start with the part of the chimney you need to cover, then confirm the configuration with your chimney professional.
A roofed cap covers one or more flues within a larger assembly. K&M’s CC100-series designs typically have an open base, screened sides and a roof above the flue area. Side-mount versions fit around the chimney; top-mount versions sit on its upper surface.
A chase cover is a metal cover over the top of the chimney chase, with openings and collars where specified for the pipes passing through it. It covers the chase surface; it does not replace the termination cap required for the chimney or vent system.
Pots create an individual architectural feature above a chimney or chase cover. Shrouds provide a decorative enclosure around visible terminations. Select the design only after confirming the clearances and compatibility required by the underlying system.
The roof shape changes the appearance, overall height and available access. Compare the drawings and options for each model before choosing a size.
Simple Multi Flue Flat Roof Chimney Cap (CC100) has a low-profile roof with a cross break to shed water. The Basic Multi Flue Chimney Cap (CC108) offers a box-style roof. Both listings describe removable roofs and top- or side-mount options.
The Hip and Ridge Chimney Cap (CC103) features a peaked standing-seam roof for a traditional appearance. Review the roof-pitch, screen-height and mount selections to coordinate the cap with your chimney.
The Concave Roof Chimney Cap / Shroud (CC101) uses curved roof panels for a sweeping profile. It is offered with a removable roof as a cap or without that roof as a decorative shroud.
The Crown (CC113) and Royal (CC107) add more elaborate architectural detailing. These designs offer cap and roofless shroud configurations; confirm which version your installation needs.
The Bell Roof Multi Flue Chimney Cap (CC110) combines curved roof surfaces with a removable upper cover. Its listing specifies minimum dimensions for cleaning access, so check this detail before ordering a smaller configuration.
The Cathedral (CC106) adds another sculpted roof option. The range also includes gable, Roman gable, barrel and covered-wagon styles. Use the product grid above and the drawings below to compare profiles.
The Chimney Chase Cover (CC200) is made to your dimensions, with a cross-broken top and downturned sides. Order the required openings and collars, or discuss a blank configuration with your installer. Larger covers may require multiple sheets joined with a pipe-lock seam.
For a cover with pipe openings, provide a dimensioned plan showing every opening’s shape, size and location. Identify the drawing orientation and whether dimensions refer to the pipe or the finished opening. Your installer should confirm the required storm collars, terminations and connection details.
A chase cover may also be part of an assembly with a pot or decorative shroud. Confirm all components separately rather than assuming a chase cover is included with another product.
Our pot designs include the Hard Hat (CC300), Lighthouse (CC301), Octagonal (CC302) and Knight (CC303). The Octagonal offers standard and large versions; the Knight offers regular and wide versions. Mounting and material choices vary by model.
For a decorative enclosure, compare the Standard Shroud (CC114) and Curved Shroud (CC115), as well as the roofless versions of selected cap designs. A shroud conceals components visually; it is not a replacement for an approved vent termination.
Confirm system compatibility before ordering: Factory-built chimneys and gas or other appliance vents have specific termination and clearance requirements. Have your installer verify that the proposed cap, pot or shroud is permitted by the system manufacturer. Do not remove or enclose a required termination simply because a decorative cover fits around it.
Consider the appearance you want, the exposure at your property and the materials available for the selected design. A finish color describes appearance; it does not identify the metal underneath.
Choose copper for a natural metal finish that changes as it weathers. Many models offer 16-ounce and 20-ounce copper. These numbers describe sheet weight per square foot, not the total weight of the cap. Weathering color and timing vary with exposure.
Many listings specify 24-gauge 304 stainless steel with a 2B mill finish. Selected chimney pots also offer powder-coated stainless steel. For coastal or other demanding exposure, discuss the alloy and available alternatives with K&M before ordering.
Many cap designs offer 0.032-inch aluminum or 24-gauge Galvalume steel with a Kynar-based painted finish. Available colors include options such as black, bronze and Copper Penny. Confirm the base metal, finish and color on your selected model.
Freedom Gray, lead-coated copper and Galvalume Plus are additional options on many models. Some other materials require a custom quote. Not every material, thickness or finish is offered for every design.
A side-mount cap has a vertical skirt that extends down around the chimney’s outside edge. The skirt provides the side attachment area. Its height and the base dimensions are model-specific, and the fit must allow the cap to slip over the actual chimney dimensions.
A top-mount cap sits on the chimney top without the same wraparound skirt. It can be useful when a smaller footprint or an irregular chimney makes side mounting impractical. Confirm a suitable mounting surface and sufficient coverage around all flues.
Have a qualified installer select the attachment and weatherproofing method for the chimney’s construction and condition. Mounting choices for chase covers and pots differ from those for multi-flue caps; use the instructions for the actual product.
For a custom quote, include your measurements, material and finish, quantity, photos or sketches, delivery ZIP code and requested schedule. K&M’s made-to-order caps and chase covers are not returnable, so resolve uncertain dimensions before placing the order.
Many K&M roofed caps have removable roofs or access covers. Check the opening size and removal method for your chosen design, especially on smaller caps. Your chimney professional should be able to reach the flues and inspect the assembly after installation.
A new cap does not replace repairs to damaged masonry, flashing or a leaking chase cover. If you are addressing an existing leak or draft problem, have the cause assessed before selecting a replacement.
K&M serves contractors and homeowners locally in North Carolina and across the United States. Production time depends on the design, material, size and current schedule. Confirm the estimate for your selected configuration and allow additional time for transit.
Many chimney caps require a protective crate and freight delivery. Plan for unloading and review the receiving requirements before the shipment arrives.

Colored Materials: The first thing to consider is whether something in colors is desired. If so, that narrows choices down to either Kynar Aluminum or Kynar Galvalume (steel). Kynar-based PVDF are coatings formulated to resist sun and weather damage.
Top Mount: A top mount chimney cap is ideally used on irregular shape chimneys, those with out of square corners or made out of stones for example. It can also be used when a cap smaller than the chimney itself is desired (which also makes it less costly), or simply if its visually preferred; when the vertical side skirt portion present on side mount caps is not a desired feature.
Side Mount: An outside mount chimney cap features a vertical mounting skirt covering part of the side of the chimney, usually around 3.5".
This is the ideal way to mount a chimney cap in most instances, as it covers the whole top of the chimney, protecting it against the weather.
Side mounting is ideal in most situations if possible.
Top Mount: Typically, a top mounted cap will be attached with construction adhesive. It can also be attached via tapcons, screws or anchors, however, this is normally not desirable as it is
something that would need to be waterproofed.
It can also be either soldered to an existing
chase cover if present, or attached via zip screws, rivets, or even the
aforementioned screws, anchors or tapcons.
Side Mount: This most common version of our caps can be mounted via screws, masonry pins, anchors or tapcons. Unlike a top mount cap, this is to be mounted from the side,
through the vertical side portion of the chimney cap base (a.k.a. skirt) which can be easily drilled. It can however, also be mounted via construction adhesive, using the underside of the horizontal portion of the base like a top mount cap.
This is only typically done because its quicker/easier, or in order not to see the side mounted fastener. This method is not as common.
Although installation is considered simple and straight forward, we recommend that it be done by a professional.
FAQs
Find practical answers about selecting, measuring, ordering and maintaining a custom chimney top.
A roofed chimney cap helps limit rain, debris and animal entry while allowing exhaust to escape through the designed openings. Protection depends on the cap design, screen, fit and installation. A cap does not repair damaged masonry or flashing, and ordinary expanded-metal screening is not insect-proof.
No. Masonry chimneys, factory-built chimneys and appliance vents have different termination requirements. Choose a cap or termination appropriate for the actual system. Have a chimney professional confirm whether a decorative cap, pot or shroud is suitable before ordering.
A roofed cap sits above the flue area and has openings for exhaust. A chase cover closes the top surface of a chimney chase around the pipes passing through it. A chase cover does not replace the termination required at the end of a chimney or vent pipe; some installations use both components.
A shroud is a decorative enclosure used to conceal visible chimney or vent terminations. K&M offers dedicated shroud designs and roofless versions of selected cap styles. Compatibility depends on the chimney system, required openings and clearances. Do not assume a decorative shroud is an approved replacement for an existing termination.
K&M offers multi-flue caps that span more than one flue. The footprint, flue positions, flue heights and required exhaust clearances must all be considered. Provide these details and have your installer confirm that the proposed arrangement is suitable for every flue and appliance involved.
K&M’s architectural multi-flue caps mount to the chimney structure rather than clamping directly onto individual flue tiles. Top-mount models can cover a smaller area than the full chimney where appropriate. Chimney pots offer a different appearance, but their mounting details must also be checked for the selected model.
There is no single best material for every project. Copper offers a natural weathering finish, stainless steel offers a mill-finish option on many models, and Kynar-finished aluminum or steel offers painted colors. Consider the design, local exposure and finish requirements. Material and thickness availability vary by model; discuss coastal conditions or other special exposure before ordering.
No. Copper Penny is a painted finish color offered on certain aluminum and steel products. A cap in that finish is not made from bare copper and will not develop a natural copper patina in the same way. Confirm both the base metal and the finish when comparing options.
Measure the intended mounting area, check whether it is square, and record the dimensions, locations and heights of all flues or terminations. Follow the drawing and ordering instructions for your selected model. For irregular chimneys, send a measured sketch or template information before ordering rather than relying on one width and length.
For applicable side-mount products, K&M’s order form lets you request an additional 1/4 inch on the length and width for fit. Follow that product’s instructions and clearly state whether your dimensions already include the allowance. Do not add it yourself and also ask K&M to add it again. Flue clearances and chase-cover opening allowances are separate details.
The required clearance depends on the chimney, appliance, termination and cap design. Screen height alone does not establish adequate clearance or exhaust opening area. Provide the height of the tallest flue or termination above the mounting surface, and have your chimney professional confirm the required space and openings before selecting the cap height.
Yes. Send a dimensioned plan showing the size, shape and location of every opening, along with the cover dimensions and required collar details. Identify the drawing orientation and whether measurements describe the pipe or the finished hole. Confirm opening allowances and any required storm collars or termination components before fabrication.
K&M can review custom fabrication and matching requests. Send clear photos, a dimensioned drawing or sketch, material and finish requirements, quantity and delivery location. Include the chimney-system information and mounting requirements so the request covers more than appearance alone.
Price depends on the design, size, material, finish, mounting configuration and selected options. Use the product configurator for available online pricing, or request a quote for dimensions and details outside the listed options. Shipping and installation should be considered separately when planning the project budget.
K&M’s custom chimney caps, chase covers and pots are made to order. The product listings identify custom-made items as nonreturnable. Confirm dimensions, options and estimated production time before purchasing, and allow separately for shipping time.
A side-mount cap fits over the outside of the chimney and has a vertical skirt for side attachment. A top-mount cap sits on the upper surface without that same wraparound skirt. The appropriate choice depends on the mounting surface, chimney shape and product design. Have your installer confirm the attachment and weatherproofing details.
Do not assume so. K&M’s standard architectural chimney caps are not sold as spark arrestors. Having a screen does not by itself establish compliance with spark-arrestor requirements. If your project requires one, have your chimney professional specify an appropriate component for the system and applicable requirements.
Only when the chimney or vent manufacturer permits the proposed arrangement. Have your installer verify the specific system, termination, shroud design, openings and clearances before ordering. Do not remove a required termination or assume that a custom metal enclosure is approved merely because it fits.
Many K&M models have removable roofs or access covers, but the method and available opening depend on the design and size. For example, the Bell Roof model has minimum dimensions for usable cleaning access. Review the individual listing and drawing with your chimney professional before ordering.
Not necessarily. Water may enter through damaged masonry, flashing, a chase cover or other connections, and draft problems can have several causes. Have the chimney inspected to identify the problem before choosing a cap as the solution. Keep the cap and its openings accessible for ongoing inspection and cleaning.
Many large caps require a crate and freight truck delivery. Shipping arrangements depend on the product size and destination. The receiver is responsible for unloading, so arrange suitable assistance or equipment and review K&M’s shipping and receiving information before delivery.
