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.

Here’s a comprehensive guide on safely installing a wood stove pipe through the roof, enriched with expert insights and personal experiences.

Understanding the Difference: Stovepipe vs. Chimney Pipe

Stovepipes connect the stove to the ceiling or wall, while chimney pipes extend from there through the roof.

Stovepipe Types:

  • Single-Wall: Requires at least 18 inches of clearance from combustible materials.
  • Double-Wall: Has stainless steel inner and black outer walls with insulation, needing only 6 inches of clearance.

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.

  2. Assemble the Chimney Pipe: Connect the chimney pipe sections, ensuring proper alignment. Secure them with screws.
  3. Flashing and Sealing: Install flashing around the chimney where it exits the roof to prevent leaks. Use silicone or other sealants to ensure a watertight seal.

Expert Tips For Installation

From my experience installing wood stove chimneys, precise measurements and high-quality materials for flashing and sealing are crucial. Double-checking the alignment of the chimney sections and securing them tightly is essential for safe and efficient operation. Always perform a thorough safety check before the first use to identify potential issues.

Additional Tips

  1. Regular Maintenance: Regular inspections and maintenance by a professional roofer can help identify and fix potential problems early.
  2. Consistent Brand Use: Ensure all parts, including additional chimney pipe sections, are from the same brand to avoid compatibility issues.
