Chimney cladding protects the chimney

A chimney cladding forms a protective shell around the existing chimney head. It withstands the constantly changing weather conditions and visually enhances the roof. We show which materials are suitable for chimney cladding, how they can be installed, and what costs consumers can expect. 

New chimney cladding: materials at a glance

The chimney head protrudes from the roof and is exposed to the constantly changing weather conditions year after year. If its surface loses its protective function, moisture could penetrate the structure and cause expensive consequential damage. To avoid this, consumers have to install a new chimney cladding every now and then. In addition to technical reasons, this can of course also be necessary when roofers re-cover the roof. In this case, you can clad the chimney to match the look of the new roof cladding.

Regardless of the reason why the work is necessary, different materials come into question. Typical are:

  • Plaster
  • Fiber cement panels
  • plastic
  • stainless steel
  • clinker
  • slate
  • zinc
  • copper

Important: When it comes to the design of the chimney cladding, the materials described can be assembled on the chimney by hand. Prefabricated inverted heads, which are simply pulled over the existing chimney on-site, offer an alternative. For a precisely fitting shape, experts have to carefully consider the dimensions of the chimney heads and the angle of inclination of the roofs.

Install the chimney cladding step by step

Once the right material is known, craftsmen can install the cladding on the chimney. The work steps can be summarized in five points:

  • Eliminate damage
  • Mount the substructure
  • Attach the cladding
  • Adjust the roofing
  • Cover the chimney at the top

1. Repair damage to the chimney

If the existing chimney has visible damage, the first step is to professionally Furnace Repair Scarborough it. A chimney sweeper can take a close look at the components and provide important information.

2. The assembly of the substructure

In the next step, craftsmen can attach the substructure. This essentially consists of a frame made of roof battens with cladding made of shuttering boards or OSB panels. While the panels are protected from moisture penetration with bitumen, any moisture that has fallen in can still escape through the air gap between the chimney and the chimney cladding. It is important to know that the roof battens of the substructure for prefabricated chimneys may only be screwed into themselves. Tradespeople can also drill holes in traditional brick chimneys.

3. Fit the chimney cladding  

Now craftsmen can assemble the required materials on the substructure according to the manufacturer’s specifications. While you usually screw panels together, sheets have to be cut to fit and connected to one another with appropriate folds.

4. Adjust the roofing and put it on  

The next step is to adapt the roof covering to the new dimensions of the chimney cladding and to apply it professionally. It is important that neither snow nor rain can get into the building via the chimney.

5. Complete the chimney cladding at the top

Finally, the chimney mouth must also be professionally covered from above. Sheets or matching concrete rings come into question.
