New workshop roof advice

[Fletchmeister]

Afternoon all

I'm stuck with a roofing problem and was hoping someone could offer some much needed advice.

I have recently moved house and a part of my house choice was made by the fact it has a 16ft sq workshop in the garden with solid concrete base as side extension.

Anyway cut a long story, the felt roof is worn out and there are leaks between the main roof and the side extension which has corrugated metal roofing.

I want a new roof quality but don't like felt roofs really so was looking at coroline bituminous roofing sheets with all the extras, wondered if anyone has used this or can offer best advice on a new roof don't really want to spend over £700 for it.

Any advice would be helpful

Cheers
Fletch

If the roof is pitched sufficiently and strong enough, I have to say there is little in cost if you are handy enough to using concrete tile rather than other corrugated products.

A decent membrane, treated battens and good tiles and the job will last 100 years.

I don't know what's best, but I've got a pretty good handle on what's worst.

Avoid metal roofs at all costs. I've got a metal roof on my garage and whenever there's a frost it just drips condensation on the inside.

Tiled roof everytime. Do it right, do it once. I've got a full pack of Sandtoft Doubles going spare.


Edit: just seen you're in Norfolk too. So my tiles might be of use.

I agree about a proper roof but bare in mind tiles are heavy so make sure the structure is substantial enough to handle tiles and a steep enough pitch for the tile you'd choose.

I've redone my garage roof in my mum's garden in May. I replaced the corrugated cement fibre panels, coroline corrugated sheets. It didn't take long to do, just used a drill and a jigsaw (a circular saw would be much better). No noticeable leaks or damage from the awful weather that we had just been through.

Have you considered using clear plastic panels instead? I realised this after fitting the coreline roof, as you would get free/better lighting during the day.

FYI, I got my panels from these guy's ebay store (http://www.roofingsuperstore.co.uk/product/coroline-corrugated-bitumen-black-roof-sheet-2m-x-950mm-pack-of-15.html ), but they don't sell via ebay anymore.

Hi all thanks for all the replys appreciate it as nice to get mixed views.

The roofing superstore was where I got my quote was around £700 for all the coroline and extra fittings with a clear panel for light.

I have never really considered tiles to be honest probably as weight and fact I have never fitted anything like that put me off but If it gave the best long lasting roof I'm all for it.

Bigbaddad where abouts are you?

I have just moved to Norfolk from reading

Presume the Felt is on Ply or OBS. If the wood is still in good order you could look at EPDM rubber which can be had for under £9/m2.

Keeps its characteristics in cold and hot, not degraded by sunlight, one piece so less chances of leaks. I have it on my kitchen extension flat roof.

[Specialone]

Out of interest, whats the meterage of the roof?
My flat roofer guy i use for jobs does it for £30 per metre, thats 2-3 layers and that will last 10 -15years minimum.

Picture of workshop would do wonders for your needed advice ;)

I'm over at King's Lynn. Done a few pitched, tiled roofs in my time. Nothing to it really.

Right there are a couple of pics one from the front and one from the rear as the rear lets you see the side section a little better.

To be honest the wood under the felt I believe is knackered it's sagging a little in places.

Ahh kings Lynn nice and local to me then

[dizzyblonde]

WOW thats a BIG man shed :D

Dunno what use it is, but my new one has been boarded out with 20mm tongue and groove boards(actually think a bit thicker, I know the walls are that thick) you can stand on it!

[Specialone]

I'm guessing from my experience, but that structure doesn't look like it's got a cat in hells chance of taking a tiled roof, it only looks like approx 12 degree pitch so your choice of tile would be limited to.

If you have to structure for a tiled roof, then buy 30-40 square metres of tiles @£8 a metre, under felt, under cloaking, lathe etc, you wont do that for £700 I'm afraid.

have used coroline corrugated sheets or similar in the past and they are crap,after a few years they sag and resemble corrugated cardboard,looking at you shed i would say stick with felt,but go for the proper thick stuff not the cheap b&q stuff that aint any thicker then paper,(felt is sold by weight & rolls are 10 meters long,so atleast 20kg rolls pos upto 38kg rolls )and if the t&g is past it replace with 18mm ply,if done well with the right mineral felt it will last 20 years

[timwilky]

Have to agree board and felt on that.

google rubber roofs and EPDM.

Should help you.

[Fletchmeister]

Morning all

I'm going to look into the rubber roofing idea this morning when I get moment at work.

Probably best to replace the roofs wood as well to be on the safe side.

I'm pretty fond of the rubber roof idea will need to get a price on that for whole roof

[Fletchmeister]

Well liking the look of this rubber but wow I think it would need a budget re-think.lol especially when the misses wants the house done

[NTECUK]

Best go for new osb as rubber last a fair old time.

[Fletchmeister]

Anyone know the cheapest place to get rubber roofing and all the bits needed?

Looking like I need 70sq metres so certainly not going to be cheap using EPDM but should be worth it in the long run.

[Airwolf]

by chace have you look at the cost for fibre glass.

my father in law git it done for his flat roof,, as it is stronger and lasts a lot longer

[suzukigt380paul]

its a shed roof just cover it with felt, its cheap, and on a roof with a pitch it will last up to 20 years,if you want to spend 3 or 4 times as much go for the rubber option, but i think its a bit over kill for a garden shed,and if you go for the felt option it will only take a few hours on a sunny day to complete

[Fletchmeister]

The words the evil words, just a shed he says just a shed never that's a kings castle just missing the gate.

Nah I get what your saying with my current car bills coming through I should go with something reasonable cost wise jus want it to last and not be doing it again couple of years down the line
