How To Poke A Hole In A Metal Roof

I was asked a question yesterday about the fire place (Dickinson Stove) and how I was able to get it in place with a metal roof. These types vents take place long before I was able to install the fire place. I will go back and talk about the process of preparing the hole for the stove. First we identified where the stove would be placed.
We then cut a hole appropriate for the shaft in the roof liner and cut out the hole in the plywood. We then covered a large 2ft x 2ft space with the same Butel tape we used around the windows and doors. Heavy Duty and very water proof. I then drilled a hole through the whole mess. We figured out where the hole would be in the metal roof and where the "fireplace chimney would be placed. Our big concern with the hardware that was provided was there was no upstream prevention plate to stop water draining down the roof from seeping in. So Stet built it with aluminum stripes I bought from home depot.

 You can see the Cardboard template that Stet used for the Chimney. I learned very quickly the "cardboard" cutout can prove invaluable to form fitting.

Add a robust amount of silicone and well you have a very water tight enclosure. We used treated 2x6 for the wood structure. It would be good to note at this point that none of this structure will ever touch anything hot from the stove. The exhaust vent from the Dickinson is two pipes in one. A center pipe vents the hot exhaust out, and the surrounding pipe vents air in for combustion. This is the way the stove works and why I have one in my boat. They don't suck air out of the space. This is a good thing in a "tiny house" or "mobile cottage".
 The almost finished product. I covered it in plastic for travel and then later wrapped it in Cedar tongue in grove to make it look like the house.

The finished product is a looking good with the bell unit that comes with the Dickinson Stove. It appears to be functioning perfectly.

Now a week since install, it is all working well.


  1. Thank you so much for putting this together! It will be really helpful for me.

  2. Mr. Boatman,
    I have been following your blog for quite a while and I really enjoy it. I think your "mobile cottage" is the best design and build of any I have seen, not to mention beautiful. If I ever build one, my goal would be an exact duplicate. It's perfect. Thank you for sharing it with everyone.
    Best regards

  3. Bill,
    Thanks for the comments. My best encouragement to you would be to dream big and know that you can build your OWN mobile cottage!

  4. That’s the advantage of having a metal roof: You can cut a hole in it anytime you want, like if you want to install a chimney, for example. Your idea of placing aluminum stripes on the roof is brilliant. That will definitely prevent the water raining down on the roof from seeping in and causing structural damage. Job well done!

  5. And I can confidently say through the 17 inches of rain so far in Portland this year, I have NO leaking issues at all.

  6. @ Zboatman. It’s great that you haven’t experienced any water leakage with your metal roof. You must be very proud that you’ve chosen metal roof for your home. Anyway, we are also using this metal roof in our home, and it has been serving us for almost 10 years. Plus, we haven’t experienced any water leakage as well. In fact, it still looks new and sturdy despite the many extreme weather conditions that had passed by.

  7. Reading this is like watching a demonstration on how to create your own fireplace connected to the roofing area. This will also serve as DIY steps to some who find it difficult to deal with their metal roofing, as well as with their chimneys. I believe that this setup will last for more years to come because of the precise execution of plans, along with high-quality materials that were used.

  10. You are right, Son Lakhani. Metal roofing offers a lot of advantages and uses. Aside from its durability, this type of roofing is like a canvas that waits for your artistic modifications and more. I’d say that the outcome of this project is pretty neat – it’s a proof of precise work and well-executed plans.
