Installing Wood Stove Pipe through Roof with Three Easy Steps

The wood-burning stove is suitable equipment to use during cold winter nights. Aside from providing cozy settings with the sound of a crackling fire, it is also able to save your wallet up to hundreds of dollars compared to other heating systems.

Now, if you have already bought it, the first and foremost step is to set it up. The following article will show you a guide on installing wood stove pipes through the roof safely.

Installing 8″ Wood Stove Pipe Through the Roof

Many people confuse and interchangeably use the terms ‘stovepipe’ and ‘chimney pipe’ even though both differ. A stovepipe is a pipe located inside the house that goes through the wall up to the ceiling. Meanwhile, the chimney is the pipe placed over it.

In short, the stovepipe connects the stove and the chimney. Therefore, the stove pipe and wood stove chimney installation processes are different.

Most black stove pipes are easily recognizable and should be complemented with appropriate roof flashing to ensure a watertight seal around the roof hole, because this color can resist extremely high temperatures. However, finding the lines designed in porcelain enamel shades to suit the stoves is also possible.

Stovepipes come in single wall and double-wall pipe types, the latter being more efficient in reducing the clearance needed from combustible materials and ensuring a tight fit at the top of the chimney. Typically, single-wall stove pipes must be distanced a minimum of 18” from any flammable furniture, ceiling, or wall – except if the combustible surface is coated with a protective layer or if the stovepipes have an extra 9” heat shield.

On the other hand, double wall stove pipes have an inner wall with stainless steel material and a black-colored outer wall. There’s a space between two layers that serve as the insulator. This type of stove pipe can be kept as near as 6” to flammable surfaces.

Here are three steps on installing wood stove pipe through the roof:

  1. Trim the stove pipe by using grinding or cutting tools such as tin shears. Skip this step if you use heavier gauge pipes, which usually come with adjustable slip joints.
  2. Once you have trimmed the pipe, seal 3 sheet metal screws on every joint and between every piece.
  3. Set the pipe between the chimney pipe and the stove and ensure the attachment is tight and rigid.

When installing the roof components for your wood stove pipe, it’s crucial to ensure that all parts are correctly aligned and securely fastened. This not only guarantees the efficiency of your wood stove but also enhances safety. Regular maintenance and inspection by a professional roofer can help identify any potential issues early on, ensuring the longevity and proper functioning of your wood stove system.

Once your stove pipe is installed, you’ll need a Class A chimney pipe, along with a storm collar that secures the chimney to prevent water ingress. For this pipe, the most cost-effective installation involves using a support box to guide it straight up to the ceiling, ensuring an insulated chimney for safety.

Make sure you stick to the same brand when connecting the chimney pipe with an additional line because going with a different pipe brand can be dangerous.
