Bit confused on how I'm supposed to re-felt shed roof.

The additional nails down from the peak will be to stop wind going in and lifting the felt.

If you are planning on having some t felt over the top you would do the additional nails at the top as the piece of felt capping/covering the peak tends to be more susceptible to being blown off aswell.

Unless you live in an exposed location, like a Scottish island or Cape Wrath, then provided the edges of the sheet over the ridge (the 'peak') are properly secured/sealed then the wind isn't going to get in and lift the felt. (this applies to all the edges, not just the ridge)

And if the location is an exposed one where the wind might do something like this then roofing felt is a poor choice of material - plastic coated steel would be a much better option.

I've never bothered with felt adhesive, nails have always been sufficient. The felt tends to stick to the roof boards anyway after a couple of years. This hot weather makes the job much easier as the felt is more flexible and tends to seal round the nails better.

I wasn't really for an EPMD job. I get that it's better & all but having seen videos & knowing where I'm at with it all I had decided to go the felt route, even if I'd need to replace it down the line vs not in the case of the rubber.

Although since it's been raised, how thick actually is that rubber? (I'm thinking cats claws... Which have wrecked part of the front of the shed).

Thanks for your input. I was wondering how wind could be a problem if it was all nailed down but you explain it well & there's plenty of air gaps for wind to get inside the shed.

Regards the adhesive - would you just do the felt overlaps & perhaps nails or would you adhesive elsewhere too?

The shed is a DIY build, not pre-built. The roofing is not ply or OSB, it's more like 5x1 or 6x1 treated timber.

Or at least that's what it is from the inside looking up. Maybe once I pull the felt off I'll see a thin sheet nailed to these 1" timbers I just mentioned.

What I'm getting at is I don't want to buy a 5ltr tin if I just need a 1ltr tin for overlaps.

Sure - use Big Phil's. He's got the gist 😁

Not an exposed area. Not the Scottish Highlands.

I can access the front & 1 side from the ground but the other side is blocked off by a fence panel wall & the neighbours shed on the other side of that wall (so I can only access roofing area from above here) and the rear of the shed is blocked off by the house at the backs huge bush.

EPDM or felt is your choice really. But I'd re-felted my shed roof three times (roughly once every five years) and didn't want to keep on doing it!

Although since it's been raised, how thick actually is that rubber? (I'm thinking cats claws... Which have wrecked part of the front of the shed).

About 3mm, 1/8". I'd be more certain of it resisting cats claws than I would roofing felt. It's also grippy enough that you can walk on it quite comfortably, so (unlike your shed front and my fence panels) cats don't need to claw it.

Definitely overlaps and under them. Few extra big spots elsewhere will do no harm too.

Thanks for the feedback.

I'm still going the felt route. Maybe in years to come I'll go the rubber way but this job has been put off for about 2 years now. I procrastinate heavily on a good day & even moreso when it's over something I'm not entirely confident in. I don't want to start throwing rubber roofing in the mix when I've spent time looking at felt & feel like I could maybe tackle it. I'll end up just not doing the job for yet another year & then grumbling about all the water getting in in 6 months time.

But I'll not be against rubber next time round.

Ideally we need a bigger shed anyway. This one is simply too small for what we need to store.

So, just a normal shed.

I had one of those years ago, got it 'free' with a house I bought.

It had a dip in the middle, front to back, and felt wouldn't sit properly, so felted it side to side with the overlap sheet in the middle.

Lasted me ten years, gave it 'free' when I sold the house.

You've now got me curious as to what an abnormal shed is.

Materials ordered last night. That hurt. :(

Probably overspent but if I was going to spend any more time questioning my questions then again it wouldn't get done so I said sod it & just bought stuff.

Treat yourself to the better felt. Wickes & B&Q do a Super Shed Felt. It is significantly better than the really chep stuff.
