How To Install Wood Stove Pipe Through Metal Roof

The chimney is one of the final elements of installing a wood-burning stove in your home. To ventilate your home and allow your stove to perform correctly, it will need to protrude through the attic and roof safely. This can be more difficult if your roof is made of metal.

Ensure proper ventilation, and ensure it’s safely exiting through the attic and your roof. Working with a metal roof is more difficult, but you are here. Cut a hole in the metal roof, apply flash, and secure the pipe to install a wood stove pipe.

Method To Install Wood Stove Pipes Through Metal Roof:

It’s critical to consult with your local authorities before beginning any chimney installation project. Because chimneys frequently require particular height clearance, it’s crucial to be cautious.

  • Pipe Flashing:

The weatherproofing of a chimney’s base is accomplished via flashing. It usually comprises thin, impermeable pieces of material that prevent water from leaking around the chimney, keeping the structure dry and free of mold.

A metal roof’s flashing is frequently constructed of metal. A chimney pipe boot is a different style of flashing. These are better suited to tiny, round chimneys and could be suitable for a stove chimney with a metal roof.

You can buy a fitting boot for your chimney pipe instead of cutting flashing materials yourself.

Steps To Install Wood Stove Pipe:

You must first analyze the position of a chimney for a wood stove on a metal roof. Mark the middle of the chimney on the ceiling, where it will be connected to the stove. Mark the middle of the chimney by drilling a tiny hole here.

  • Adjust The Position Of Stove:

Place the woodstove where you plan to install it if you haven’t already. If it’s already installed, you’ll be ahead of the game, and your task will be easier. Use one part of the chimney pipe as a guide at the stove connection.

  • Mark The Positions:

Mark the center of the pipe on the roof’s sheathing plywood using a plumb bob from the ceiling. Drill a pilot hole through the metal roofing where you made your mark. This is done to create a physical hole in the core of the chimney.

  • Mark The Chimney Hole Diameter:

The next step will be simple if you have access to a drawing compass. Take it and measure the outside diameter of the chimney hole. This should be done on the metal roof’s outside surface. Always keep an eye out for the manufacturer’s standards and any applicable building codes.

At least two inches of space between the pipe’s surface and the surrounding material is normal. When the chimney is used, having it too close can provide a fire hazard.

  • Use Jigsaw To Cut The Hole:

Use a combination blade on your jigsaw to cut a hole in the roof and the plywood. Place the flashing over the hole you just created. Move the flashing down a few inches and use a pencil to draw a line to the top of the edge.

Before moving on to the next step, cut across the flashing where you set the line using sharp snips.

  • Insert Pipe Flashing:

You can now place the top edge of the flashing under the roofing and roofing paper after cutting a line. It should cover the chimney pipe hole completely. Raise the roof slightly to apply a bead of exterior grade caulking.

This should extend above the flashing’s surface where the roof ends. Rep, this time is pressing down under the base’s perimeter edge to adhere to the flashing.

Obtain the chimney’s instructions and properly assemble it. Insert the chimney, including the flashing’s collar, through the roof hole after it’s finished. Place the bottom of the chimney on the flange of the woodstove.

Wrap Up:

When you have a wood stove, having a double-wall pipe is necessary. A single-walled pipe will heat up and ignite the surroundings around it. You can spread the heat out more by utilizing at least two pipes, which prevents the pipes from becoming too hot to cause a fire.

Finally, follow the instructions guide guidelines to install the chimney cap. Fill each side of the flashing with a little amount of caulk. To keep moisture or water out of the collar, wrap it around any gaps.
