Fitting A Silicone Roof Flashing

In this article and the video below, we’ll guide you through each step to fitting a silicone roof flashing. This guide is part of our series of short videos that will show you how to install a small wood burning stove into a van, a shepherd’s hut, a tiny home or an RV – any vehicle really that has a metal roof!

Fitting a silicone roof flashing is a great way to install your flue system into a shepherd’s hut, a van or a tiny home, as the malleable aluminium edge of the flashing can be formed to fit the contoured metal profile of your roof. Your shepherd’s hut or tiny home might have a roof that’s made of wriggly tin, and our silicone roof flashings by DEKS are perfect for the job! You can also get them in a round or square shape to suit your preference.

To learn more about fitting a silicone roof flashing, you can watch our instructional video below, or you can follow our step-by-step guide, which is explained in this article.

Step 1 – Mark Out The Hole In Your Roof For Your Silicone Roof Flashing

First, you will need to cut the hole in the metal roof itself. A great way to do this is to use your trim plate as a guide – you can cut a hole which matches the internal hole of the trim plate, as this is just a bit larger than the diameter of the flue pipe.

This method is perfect for working out how big the hole in your roof will need to be, and it ensures a tight fit for your twin wall flue pipes. It’s also worth noting that you will need to maintain at least 50mm of space from your twin wall flue pipes to any combustible materials, such as wood. If your roof has a curve in it, then the hole will be slightly elliptical. An oval/elliptical trim plate can still be used a useful guide for marking out this initial hole!

Step 2 – Open The Fixing Kit And Cut The Silicone Roof Flashing To Size

You will also find that our silicone roof flashings come with a fixing kit, which includes:

  • A tube of silicone.
  • Some self-tapping fixings/tech screws.
  • Some plastic caps to go on top of the fixings.

After placing your flashing over the hole, you will need to trim the flashing down to the correct size. We strongly recommend that you do not cut the flashing downwards, as this could potentially make a run. Instead, it’s best if you use a Stanley knife to cut a ring off the top of your flashing to make it the right size.

Step 3 – Mark Out The Positioning Of The Tech Screws. Apply Silicone Underneath The Roof Flashing And Fix It Into Place.

You can then mark the outer edge into sixteenths, which is where you’re going to apply your 16 self-tapping fixings. Next, you can lift up your flashing and apply a zig-zag bead of silicone under the edge of the flashing. You can then carefully push the silicone flashing over your twin wall flue pipe, ensuring that there’s a tight fit. The flashing will stick to your roof, and the malleable edge forms nicely around the contoured profile of your metal roof. Fitting the silicone roof flashing is a fantastic choice if your roof is made out of wriggly tin, for example.

Step 4 – Fix The Self-Tapping Screws And Caps Into Place

You won’t need to drill any holes for the screws, as they will self-tap into the roofing material. To fix them into place, you will just need a good cordless screwdriver with an 8mm bit on the end!

To ensure that the silicone roof flashing is fitted evenly, it’s a good idea to put the tech screws in the order of a 12 o’clock, 6 o’clock, 9 o’clock and then a 3 o’clock positioning. You can then gradually fill in the segments as you go around until all of the screws have been put in, before adding the plastic cover tops.

To fix the caps into place you can add some silicone on top of the heads of the fixings before applying the plastic caps, or alternatively, you can put a spot of silicone inside the cap of the plastic covers and then push them onto the self-tapping screws. If you have any silicone left over after fitting your silicone roof flashing, then you could apply an extra bead of silicone around the top of the flashing for some added weather protection.

Step 5 – Fit Your Remaining Flue Parts

You can also add a storm collar to your flue system, as this will prevent the silicone roof flashing from UV degradation. If you don’t like the orange colour of the flashing, then you can always spray it black. If your roof is at an angle, then you can trim the tangent off of the storm collar itself – again, you could also apply a bead of silicone around the top of the storm collar for some extra weather protection.

Finally, you can attach your rain cap cowl and secure the locking band! A useful addition to your van flue kit is a closure cap, which is included in both of our van flue kits that we’ve designed. If you’re on the motorway or passing under some trees, for example, then you can easily replace your rain cap with a closure cap, to ensure that your flue system remains intact. When you’re parked up, you can easily switch them over again, or you can also add an extra length of flue to improve the draw of your flue system!

If you want to see how other people have installed our small wood burning stoves into their vehicle, make sure you check out our shepherd’s hut case studies, our tiny home case studies, our case studies for vehicles and RV’s or our horse box case studies!

If you’re installing a small wood burner into a van or a canal boat, then you might want to consider adding our gallery rail option to your small wood burning stove! This will enable you to safely retain any pots and pans or a kettle on your stovetop whilst you’re in transit. Your Hobbit stove or Hobbit SE can be fitted with a silver gallery rail or a brass gallery rail, and you can make full use of your stovetop and gallery rail by exiting your flue system from the rear of our small wood stove. We have designed a number of installation kits that exit from the back of our stove, or you can just purchase a rear exit kit if you already have the other flue parts that you need.

It’s also likely that you’ll be pretty tight on space when it comes to installing a small wood stove in a van, and our heat shield option for your stove halves the distances that you will need to maintain when installing your stove! You can read more about this option here.

Our Hobbit Stove Has Been Fitted!

"We had a Hobbit stove fitted this week by Alex Reay from Flues and Fires, and I just wanted to get in touch to say it is AMAZING and we love it! We have a lovely cast iron tiled fireplace which I was desperate not to lose when we installed a small wood burning stove, but until I found the Hobbit on Google, everyone told me it would be impossible to keep the fire surround. The Hobbit is perfect - not only does it fit very snugly, but it looks fantastic and the blue door complements the tiles very nicely. We are sitting enjoying a fire now and absolutely loving it! Thanks for creating such an amazing product."

The Best Stove Ever!

"It’s the best stove ever! It’s easy to light, very efficient, burns anthracite and stays in overnight (ours has been in for three weeks now). It even keeps a kettle of water at the ready for a cuppa! What more can I say, we love it! Just the thing to make our Yorkshire home cosy, and the cat loves it too!"

First Small Stove Installation

Was looking for a small stove for my first self-install. Found Mark very helpful. Knowledgeable, friendly service. Stove burns well and generates lots more heat than the previous open fire. What is not to like?

A Huge Thank You!

"Dear Mark and Gill, a huge thank you for designing and making the Hobbit stove! We had two different London-based fireplace companies tell us that we simply had to knock out the old cast iron and tile fireplace to fit in a woodburning stove, and that there was no other option! Then we found you online. We are delighted with our little Hobbit, which swallows up logs and kicks out a good amount of heat. Perfect for the winter! I will also be writing to the London-based fireplace companies to put the Hobbit on their radar. Best wishes."

The Little Hobbit Has Stepped Up To The Challenge!

"We just wanted to say how impressed and how much of a life saver our little Hobbit has been! It was fitted a few months ago in our holiday home in Rhu, Scotland, which is a large open plan conversion in a Victorian house. This weekend our boiler decided it was not going to play ball. The little Hobbit has stepped up to the challenge, providing heat to a very large area, about twenty eight foot by twenty four foot with a high ceiling of about eighteen foot, keeping the room reasonably warm, warm enough for us not to use cardigans!”

Our Pride And Joy!

"What a fantastic fireplace with the beautiful Hobbit stove. It fits perfectly into the small space and throws out a lot of heat. Here's a photo of our little stove, now our pride and joy and much admired by all who see and feel the warmth."

Fantastic!

"Just to bid you all a Happy New Year and to say how much we’re enjoying having our Hobbit stove! It was easy to fit with the help of your excellent ‘how to’ videos and we’re just awaiting our inspection by building control for the certification. The Hobbit has fitted neatly into the hearth vacated by the old gas back boiler (with a little cosmetic rendering) and never ceases to surprise us how much heat it can deliver to the point that the new condenser boiler is having an easy life, thereby saving us on gas bills too! Everyone loves having a ‘real fire’ in the living room."
