Has anyone used EPDM rubber for a shed roof?

I have a 10'x8' apex shed, with a tongue and groove board roof that I really need to get sorted as I temp fixed it using breathabale roofing membrane, but I noticed some leaks after the storm we had recently and I have some expensive tools in there I'd hate to get ruined. Just wondering if anyone has roofed their shed with EPDM and if they have any input, tips and a good place to buy it.

Also wondering if i'll have to buy some ply/OSB to fix over the T&G roof, or would it be ok to adhere the rubber to the T&G? I'm thinking the movement in the timber might affect the rubber, or will it just expand and contract with the timber?

If I use water based adhesive, will i need a small pot of contact adhesive as well for edges?

From a quick look around on ebay it looks like I could get a sheet of 3.5m x 3m 1.2mm EPDM and a tub of water based adhesive for around £100, which seems pretty good if it will last 20 years.

Thanks
 
If it's only a temp solution just use a tarp sheet - strap it down well - The roof on my shed is T&G and I had to do a quick fix 10 yrs ago (quality felt) when bought this place - It's still water tight- If it did go I would certainly put Ply sheets on first then that metal profile roofing on top although good quality felt would do.
One thing to watch for is a dip in roof end to end - mine is at least 10 ft long and it didn't have a center truss so jacked it up and made one in situ.
 
The roofing membrane worked fine on the other side and lasted a good few years without leaking. It's lasted so long its actually covered in moss! The other side I did recently started leaking after the first storm, so I'm guessing it was because I stapled it on as I didnt have any felt nails.

I'm thinking of going for this as it has the EPDM and tub of water based adhesive and a tub of contact adhesive. I was hoping someone might know a bit about it as I have no idea what brands are any good, or if they're all pretty much the same thing.

Is it worth the hassle when good shed felt can last 15+ years and only takes a couple of hours to replace?

From the videos I have watched, it looks like it would be less hassle to fit than roofing felt. I'll have a look into decent roofing felt and see how it compares in price. I just want something that I can fit and forget about for 10+ years.

Hi Mark,



I did my Home gym 2 years ago, its really easy to do make sure the woods fine underneath and flat, mine was a new log cabin so was very flat.

Ive used felt for years but after using this rubber will not go back, i am about to start a shed cocktail bar by extending my other shed i will remove the roof and install a flat roof and yet again install the epdm on it, its a job you will do and never worry about leaks again :)

I did not bother with any trims i used the wood to do that saved about £200 on my job as you can just about see on the picture.

I got my last rubber from rubber4roofs and will order from them again.

Good luck

That looks really nice.
I need to do the same with other halfs gym as well. Wind managed to get under the felt last year and tore a bit off. I rescued it and nailde it back then used a roof sealant to waterproof. I am planning to do some roof insulation this year. Going to add probably 50mm of solid to the top, then cover that with a thin ply to screw through into the main roof. Over that a EPDM rubber I think.
 
I built my new summerhouse/shed a couple of years ago and used the supplied felt however, it immediately started leaking, so ripped it all off and fitted an EPDM roof. Did it by myself so it was pretty straight forward.

It was applied directly to the t&g roof boards. If I remember correctly, as you apply, you apply the glue to both the roof board and the rubber and then roller it down. I then finished the edges by screwing the trim boards on. Been absolutely perfect and would use again.

I bought from Permaroof and it was around £125 for the rubber and adhesive. https://www.permaroof.co.uk/

To anyone felting a roof "Do not use staples" They used them on my new summerhouse and on first winter water leaked in -This is because staples do not have round head nails have and this allows water to run down staple legs and into wood T&G - The reason they use staples is the roof timber is only 9 or 10 mm and felt nail is 11mm - If you have a choice - spec at least 12mm T&G for your roof covering and use nails..
 
Thanks guys, I have applied for a free sample/info pack from Permaroof. I'll also check out rubber4roofs, which I think sell the same EPDM as the link I posted from ebay.

It's good to know that you can go directly onto the T&G, that saves having to buy ply as well.

Thanks

The insulation is definitely a good move, I added it to floor and roof and in all honesty I have used the heater for no more than a hour in about a year, once them weights are being thrown around I end up opening the door and sometimes the side window to keep cool. After 5 mins it's toast warm in the really bad cold spells then the workout keeps me going and I turn it off :)
