When the stove pipe goes up through the roof, the hole around it has to stay dry for years, not just for the first rain. A cracked or loose boot is how water finds the ceiling. Choosing the best stove pipe boots is a small job that keeps the roof tight around the pipe: silicone or EPDM flashing that stretches over the pipe and screws down to the metal. This guide compares four stove pipe boots by what their listings actually state: pipe size, temperature rating, base shape and what comes in the box.

Specifications are manufacturer rated, collected 23 October 2026. Two listings state a warranty with a term, the Sobalai with 2 Years and the Fasteners Plus with a 35-year warranty, and none names a safety standard, so all four score zero for safety.
The best stove pipe boots for a metal roof
How we scored them
Each boot is scored on performance, build, value, safety and warranty, using only what the listing publishes. The weights are on the site’s How We Pick page.
| Product | Woodlot Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Fasteners Plus #7 | 9.8 | 32 | 21 | 21 | n/a | 5 |
| Sobalai #3 Red | 9.6 | 29 | 20 | 20 | n/a | 3 |
| Aothotop #7 | 9.6 | 30 | 20 | 20 | n/a | 0 |
| VIVIDA #6 Gray | 9.5 | 28 | 19 | 19 | n/a | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score. Safety counts only for powered gear or where the listing states safety features; where it does not apply, the score is taken over the remaining 90 points.
Buying guide: choosing a stove pipe boot
Pipe size
Boots are sold by number, and the number is a size range, not a pipe diameter: the #3 here fits pipe OD from 1/4″ to 5 3/4″, the #6 fits 5″ to 9″, and the #7 fits 5-1/2″ to 11-1/2″ on the Fasteners Plus or 6″ to 11″ on the Aothotop. Measure the outside diameter of your pipe and pick the number whose range covers it. The Sobalai and Aothotop listings have marked cut lines on the cone so you can trim to the pipe size, and the VIVIDA warns against over-tightening the screws.
Round or square base
Three of the four boots here have square bases and one, the VIVIDA, has a round base. The VIVIDA listing recommends a square base when the roof pitch is greater than 10/12, and the Aothotop listing says its boot fits 10/12 to 12/12 slopes. A flexible metal base that can be molded to the roofing ribs matters on corrugated metal, which all four listings describe.
Temperature rating
Heat is the point of these boots, so read the rating, not the color. The Sobalai and Aothotop list a maximum of 500°F and a minimum of -100°F, the Fasteners Plus lists 437°F continuous and 500°F intermittent, and the VIVIDA lists -165.2℉~446℉. Stay inside the listed range: the VIVIDA listing says the boot will not perform properly when the temperature exceeds it.
What is in the box
A boot without screws is a trip to the store, so check the kit. The Fasteners Plus #7 ships as a complete kit with sealant, 45 stitch screws and a magnetic nutsetter, the Sobalai #3 brings 50 roofing screws and two hex sockets, the VIVIDA #6 includes 25 screws and an 8mm hex socket, and the Aothotop #7 includes roofing screws and a hex socket.
Wear eye protection and gloves for cutting, splitting and handling, follow every tool's manual, install stoves to code, and have the chimney inspected and cleaned every year. See EPA Burn Wise and NFPA heating safety. Read our Safety Disclaimer.
Around the Woodpile
- Match the boot number to the pipe outside diameter: #3 for 1/4″ to 5 3/4″, #6 for 5″ to 9″, #7 for 5-1/2″ to 11-1/2″ or 6″ to 11″.
- On roof pitches greater than 10/12, the VIVIDA listing recommends a square base, which three of these four boots have.
- Stay within the listed temperature range: 500°F maximum on the Sobalai and Aothotop, 437°F continuous on the Fasteners Plus, 446℉ top on the VIVIDA.
- Do not over-tighten the screws, per the VIVIDA listing: snug is enough to seal the base to the roof.
Frequently Asked Questions
What size pipe boot do I need?
Measure the outside diameter of the pipe and pick the boot number whose range covers it: #3 for 1/4″ to 5 3/4″, #6 for 5″ to 9″, #7 for 5-1/2″ to 11-1/2″ or 6″ to 11″. The Sobalai and Aothotop listings mark cut lines on the cone so you can trim to your pipe.
Do stove pipe boots work on steep roofs?
For steep pitches the listings point to square bases: the VIVIDA listing recommends a square base when the pitch is greater than 10/12, and the Aothotop listing says its boot fits 10/12 to 12/12 slopes. Three of the four boots here have square bases.
What temperature can a silicone pipe boot take?
Per the listings, the Sobalai and Aothotop take up to 500°F, the Fasteners Plus takes 437°F continuous and 500°F intermittent, and the VIVIDA is rated -165.2℉~446℉. Do not run them past the listed maximum: the listings say performance falls off outside the range.
Do I need sealant with a pipe boot?
The Fasteners Plus #7 ships as a complete install kit that includes sealant, 45 stitch screws and a magnetic nutsetter. The other three listings describe screws and hex sockets but no sealant, so read the box contents before you climb up.
How do you install a stove pipe boot?
The listings describe a simple job: confirm the pipe outside diameter, cut the cone at the marked ring that matches it, slide the boot over the pipe, and screw the flexible base to the metal roof with the included screws. The Sobalai listing says the job takes about five minutes, and the VIVIDA warns not to over-tighten the screws.
