Roof sarking peeling off?

A homeowner asked, “is this roof sarking peeling off?”

I’ve installed a lot of sarking!

You need to apply the special shiny silver insulation tape that is sold especially for taping reflective foil laminate. It’s called sarking (or sisalation paper).

It is sticky and most importantly reflective, long-lasting and it maintains the integrity of your sarking layer.

Here is a photo of the tape we use. It won’t break down or delaminate, it sticks to wet surfaces, is stickier than cloth duct tape, and withstands a broad range of temperatures from -30% to 100%.

Is it just a matter of taping the edges? Do I need to put anything on the inner part too to stick them up?

You just smooth the bottom layer over the top layer and run the tape longways along the edge of the overlap, so it goes half on each side.

You could hold it in place with a couple of little sections of tape but replace them when you get to that bit with the tape roll.

Once the edges are taped and securely in place you can run another line of tape to offset each side to widen the taped join.

Bare hands are best as the tape sticks very strongly to silicone gloves!


What might be the reason that this happens to sarking?

It looks like it wasn’t taped in the first place. It’s important on a metal roof as the taping ensures the condensation doesn’t drip on the ceiling, and it has benefits for tiled roofs too, e.g. drafts and radiant heat as sarking is high thermal and drastically reduces heat getting into your roof void.

Sarking is now mandatory in building. Installation of sarking has been a standard practise since 1996.

Do you need Sarking Installation?

AllCoast is very experienced at installing sarking.

Sarking installation typically includes:

  • Lifting roof tiles from the battens and stacking them across the roof
  • The battens are then removed and de-nailed ready for refitting
  • Damaged battens are replaced
  • The sarking AllCoast supplies is a heavy-duty poly roof sark, this is run across the rafters lengthways creating a permanent barrier under the roof tiles
  • After the sarking is installed, the battens are nailed back onto the rafter
  • Valley seal is installed to all valleys
  • Roof tiles are relayed using the new spring tile clips causing less issues
  • Broken tiles are replaced as necessary

The work outlined above comes with a 5-year leak free warranty. Sarking has also a high thermal quality and will dramatically reduces heat in the roof void.

Wayne and his expert roofing team are the ideal trades team. From the initial call for a quote to the follow up after the job was complete Wayne and AllCoast roofing were a delight to deal with. The quote was not the cheapest or the most expensive but the finished product I have no doubt is the best possible. Our roof was checked over, an accurate assessment made, and value-for money quote provided. Then the very thorough cleaning, repointing and renovation work, and finally painting were all carried out by their respective tradesmen in a thorough and professional way. After dealing with a few other trades for other services I can honestly say AllCoast roofing is the best in the business! Thank you Wayne and team, I love my updated roof!
