- Full roof structure build tutorial. We use 5x2 c16 for these roofs as height is everything as you know. If its more than 3mtr span we double up on the timbers. Ive built this alone today whilst trying to do you a video to show how its constructed, so please excuse the poor camera work. Thanks for watching

Love the upside down roof hangers tip , wish I had thought of that when making my carport
This needs to be said. Thank you for taking the time to do these vids mate. When I'm building my man hut /grow room these vids will be useful as.
Grow room 🤣
william griffin if I can do it with pallets I'm sure as I can do it properly with a little help form your vids mate👍🏻
That's a solid roof, you could save money and make your own timber beams for over those wide door ways. Laminate two 5" by 2" with a rip of 1/2" plywood in the middle, 👍😁🔨🇮🇪
My hat goes off to you mate all on your own still managed to film 🥳
Appreciate the time you take to make these videos. Full of detail and explained simply. Keep it up 👍🏻
Great job Liam .... you make it look so easy and brilliantly described .... you're getting me motivated to do my own garden room 😊👍
absolute brill, im just starting a build 16ft x 10ft and was unsure about the overhanging roof, this has helped 110$, very informative. Thank you
Great video and your opening with the white board is a real help to give us an overview of the project. 👍 Thanks for taking the time to film.
Brilliant illustration on the video will and good way of getting over constructing a rake wall by setting out to the lowest height with that extra bit of timber filling the void. Regards Pat
Enjoyed the slower pace and higher detail in this one. Thought I was in for a rollercoaster when I seen you had released a vid over 3 mins long, but no. Nice and chill. Cheers mate.

Decent, finished the back wall today and should be ready with this by the end of tomorrow! Such good info, thanks
ive watched so many of these types of vidoes and i have to say yours is the best. no nonsense and straight to the point. great quality builds too. ( im an Construction Manager )
How would i calculate what size of roof joints i need to use for 8 m long x 3.5m wide with 400 spacing
@@staceycook5067 6x2 joists (150mm x 50mm) will span 3.5 metres at 400mm centres but if you are restricted by overall height then you can use 5x2 doubled up ( gets very expensive that way considering your practically using twice the timber)
This is by far your best video. MasterClass in how to do a flat roof. I’m going to copy this step by step in the next two weeks doing my own shed. Cheers again. Love from Ireland 🇮🇪
Did you do your shed?
@@pofrani I did actually. The dance studio is up and running!!!
Have never built anything in my life but have watched all your videos probably 6 times over and am at the roof stage of a 4m x 5 m man cave build messed up once or twice but buzzing how well things are going so far would not have even attempted to do this without watching your step by step videos that you made using basic tools hat of to you for taking the time out to teach others and always having a smile on your face thanks!!
PS thanks my missus thinks I am great?? Not bad for a dumb scaffolder?? Appreciate what I have done thanks to your knowledge 😊
How did it turn out?
Can't tell you how useful this video is mate. Gonna watch through all of em now
great video - I am now fully addicted to your build projects
Glad you enjoy it!
Another amazingly informative video, that thankfully breaks down your longer start-to-finish video I've watched numerous times. It gives intricate tips that I wouldn't have considered before, such as striking the string line between roof joists, rather than measuring. I'm hoping to start my garden office in a few weeks, maybe I'll make some vids to show how I've used many of your techniques.
I’m going to build myself a garden room and this has really helped me. Thank you
King of the garden rooms strikes again with another informative tutorial and filming it solo . Top man.
Great video. I didn't realise you did all that additional strengthening on the sides of the roof overhang. 👍
Hi Liam - Started by build today, rods are in!
Shoes and floor joists arrive Monday... Its harder than your team make it look - especially asa 1 man crew..
I've watched a few other providers, one of them wrapped the bare stud walls in membrane - no OSB at all and even rested the floor joists on a few old bricks, unevenly stacked - cowboys....
GEAT video. Need a camera crew!!!! Great instructions and overly informative. 10/10. Proper helpful!!!!!
Good to see you back and with a smile. Great information on that roof. Keep up the good work
That was one video that I’ve wanted to see. Thanks Liam for another detailed build 🙏👏
Excellent video as always. Thanks for sharing.
Super helpful as I’m about to build my own 5x3m workshop. Had been trying to think about how I might attach my roof joists and hadn’t considered using joist hangers upside down! Genius, I’m also a fan of overkill where it makes sense. Cheers!
love over engineering! lets me sleep at night!
I'm just about to do my own shed and all your videos have been really helpful, your work is top draw. Thanks for the videos 👏 👏
Watched loads of your videos and still enjoying and learning new tips - thanks - top job!
Cracking video Liam. Lots of detail. Well present. Thanks.
Cheers for this. I'd be really interested to see up close how you detail the corners of the single ply membrane and fix the edge trim & guttering. Maybe you've covered that already in a previous episode but I must have missed it. 👍
Just found your channel last week currently watching all your videos back.. Great content keep it coming. 👍🏻👍🏻👍🏻
Hi Liam I’m about to do this roof tomorrow. Ive done the wall the past few days from watching your videos. The shed is 14ft by 11ft
Quickest way ever to do walls and plywood. Wish me luck for the people of Ireland!!🇮🇪
You’ll smash it mate 🇮🇪
@@thegardenroomguru didn’t go according plan Liam. I put the rafters in at 400 gaps but left my sheets of plywood for the roof i have to cut now. Think from the video you put them in 400 gaps to suit the insulation. I only noticed it towards the end of the rafters been finished!! No big deal to cut the Plywood.
saving this for spring, need to scrap the current summer kitchen roof, the guy who built it was an idiot
Brilliant! Love watching you and you explain it so well.
Brilliant videos, always! Really enjoy watching them.
Saving this. Love the video, thanks, super helpful
I’m so grateful to you for all this excellent advice - I owe you a beer!
Lovely jubbly. Good day's work on your own!
Class, great information,thanks fella!
Fantastic video 👌
Yahoo, a UK vid. Full of the nitty gritty we need to know and see, where the roof is the star and not the wannabe TV presenter.
Yet another great video explaining things. Could you possibly do a video on how to work out the best way to position the 8'x4' OSB boards & T&G roof boards you use on the roof. Thanks
Boarding out is the next one mate. Should be on the end link 👌
Awesome, thank you for the reply
Beautifully over engineered; just how I like to do things 👍🏾
Thank you for making these videos. They have helped me greatly in making a shed and now I am working on a covered deck.
My question for you is my structure is 3.658m x 4.877m ) 12 feet by 16 feet)
In your video you mention briefly that if the span is over 3 m I would have to double up the joists.
Can you expand on this please.
Thank you,

Its nice work, only thing I'd of done different is done 3 noggings, one center then the center off those. You'll be supprised how much that with slag over the years with just the 2, it's a big roof.
Hi, I'm a keen diyer and have just made a 6x6m garden room with 8x2" rafters. I've only put in 2 rows of noggins in, do you think I should add another row in between these two. I've used 18 mm osb for the roof decking and covered with grp fibreglass.
If it’s 6mtrs x 6mtrs you definitely want another 2 rows I’d say 👌
@@vjd8574 generally every 1m you should really have a nogging because it's such a large span. Takes abit more time but doesn't cost much more. Better safe than sorry. Last thing you want is in 5/10years time water pooling because the roof dipped.
Great job . I'm hoping to sort my masonary roof out ASAP.
3.4m death amd 3.3m width it has a single potch (not truly check but will ) of about 15° shitty tin corrugated . No insulation .(although I did initially follow a roofers advice if fixing some below roof sheets deeming useless).
So thinking new joists (original 4x2 were laid flat side meaning less strength. There's an rsj as additional support central perpendicular to joists .
Joists are rotten..so thinking osb 15mm sheathing entire roof section over new 4x4 400 centres as the rsj will give it extra support ..then membrane (gor that already) and reppace metal sheets maybe some additional insulation pir underside leaving air gaps ?. Ty in advance
Nice work btw neat
Excellent work 👌🏼
Fantastic mate. Another great video. How do we go about purchasing the generic plans? 5 x 3 would be perfect for me please.
Nice video with good information. I have a double size garage (5.2 x 6m) in brick that I am going to put a sloping flat roof on. The tiled roof was ready to collapse so I removed it but kept the brick work, with some remedial work. Can you comment on the roof plans for this size, keeping to the standard height of 2.5m. Thanks in advance Stuart.
Great video very helpful
Hi would single 7x2 work on a span of 4 meters. Enjoying your videos great work
Did you find the answer to this, as I have a 4 metre span to do also, thanks?
Check span tables. Ali dymock has them on his website and in his garden room videos.
Hi mate,
Would it please be possible to have plans for a 3m square shed roof?
Great channel,
Regards
John.
Nice video like it
I am so tempted to start a project like that but unfortunately, I know my limits. Keep making such videos and one day I will. Just wondering when you say 25 mls ( is that 2.5 cm for every meter?). I don't know if I can change my garage roof like that. Brilliant work Mate.
Mate, I’m not here to sell to you, join the Facebook group, home builders building brilliant builds, get the base right, the rest is 🕺🕺
great watch pal
Good job. I'd be careful with the Radio playing in the background, you might get copyrighted for the songs playing.
👀😬didn’t even think 🤔 is that a real thing??
@@thegardenroomguru Yes it is, you are considered to be broadcasting for entertainment and require a licence, so I would mute the music while filming. :)
Amazing job
Thank you for your advise.
I need to build a shed adyacente to my house.
Please how to install tha beams fix to the wall how to seat the roof supports to install he first beam.
There will be an inclination of 75cm.
Thank you
Thank you so much mate!!
Top video, nice and clear advice!
I'm planning a similar size workshop for my Mrs although in block. Just wondering, do I need to level the ends of the rafters where the facias go, or is a 25mm per meter drop so slight it won't show? Cheers.
You won’t see it mate
@@thegardenroomguru thanks, less maths to do, hooray!
@nostalgicplastic4323 😂a few have asked this before on my Facebook group mate, it’s like 2 or 3 degrees, never notice it 👌
brilliant job how do you get the noggins in a straight row im doing something similar i have done one before but used hangers for the noggins I don't want to stagger them 😊
chalk line mate, or fire a straight edge up and mark all the roof timbers
ok thanks mate I must of been drunk I ment to say I done this with decking used joist hangers to get them all in a row you don't have them did you drill in from the sides because you can't nail or screw from behind each one 🤔🤔
How do you do a roof where you have limited space at the back and want no soffits ? Is is possible. Great vids.. Very useful
Thanks for the video. 10.35 how will this block sit on the timber? Your rafters are angled, so there will be a gap between this block and the stud below. How will it float, just on two screws?
its nailed into the 5x2 that goes on next as per the video mate
@@thegardenroomguru cheers
Liam, love the detailed videos. Hoping to start a project like this. Would you have a materials list for a 5x3m build??
Yes mate, there’s 13 different size options on the website and a 5x3 is one of them
Good
Useful and clear
Good stuff! I'm looking at cladding options for the back and side of my build that wont be seen, could you recommend any sheet materials I could use instead of feather edge. Keep up the good videos.
Thanks for the great video.
Does the perpendicular small joists for side overhang needs joist hanger or using just screws are fine.
Thanks
Can anyone give an answer, making a horizontal roof with 5 x 30 cm wood boards / joists (30 cm being vertically) would the boards in 5 meters length bend from it's own weight and snow ? And what is the max spacing allowed between boards, is 70 cm enough ?
Do your side walls have a slope at the top to follow the roof or do you fill this slope in afterwards, once the roof is on?
I.e. side walls are built straight and level at the top.
side walls are level mate, fill the gaps after which intern supports the side overhang
Great video! Explain everything really clearly and easy to understand. One thing I don't quite get though is where the first ceiling joist goes in relation to the wall. Does it run directly on top or are you bringing it in a bit? If so, by how much? Cheers
Bit hard to explain with our an image, but your side wall internally is flush with the outside of the 1st joist, so if you looked up from inside you would see the full underside of the joist, if that makes sense
Thanks for all the videos you post! I'd love to see another video of the cladding being installed, particularly on the side walls where there is the pitch of the roof to contend with, do you cut the top of the vertical cladding to the angle of the roof and measure each plank? Also, do you cover that detail with a trim? i.e. where the top of the cladding meets the soffits. Thanks
Gary Dixon ok, so we used to cut each piece individually with a degree angle on the top, measured to length........ then I thought, wtf, cut them square, over sized, 20mm bead to the top to cover small gap, multi tool bottom level, looks 100% 👌
@@thegardenroomguru thanks, makes sense. Top man.👍
Brilliant videos, can't get enough of them. Are your side walls the same height as back wall? Or are they rake walls? Thanks
Fab and informative video, thx. Two questions, 1) if your roof joists were long enough, would you have used upside-down hangers at the rear as well as the front? 2) Would liked to have seen how you add the noggins... Obviously nailed from the side right?
only use the joist hangers because I can't get a decent fix over the steel, if I can I spike the timbers into th wall head plate, ill do a fuller video on the next, had a bit of a mare, with the timbers being too short and being on my own
@@thegardenroomguru your fix was really interesting. I learned a great from it. You're a real craftsman.
If I wanted to build a shed that was 13ft x 14ft (so very nearly a large square) and have an attic in it, what size thickness wood lengths would you use to guarantee structural integrity across that much of an expanse? I mean the lengths that the attic floor would be on? Thanks
Hello nice video I am planning to build a 8 by 8 did you use 2 by 4 on the roof and joe long are they thx
3987 x 6112 what joist would you recommend, mancave set up . With slope
Cheers
Love this video!
I can’t wait for the generic plans to go up - looking for 6m x 3.5m with bifold doors, and a corner window 😇 is it a pain to put a skylight in?
Brilliant video, I’ve learnt a few things from this flat roof series, what size nails are you using for the frame? I noted you said 63mm for the osb to frame but I take it it’s like 90mm for the frame ones?
Hiya I'm doin a flat roof on my dad's house, it's 5m x 5m what size timber would I need and at what centers..many thanks matt
Hi Liam you said this was a 3x5m and that you ordered 3.6 m for roof instead of 4.2 I thought with a 300mm overhang either side 3.6 would be perfect am I missing something? I’m building to the same dimensions and had planned on 3.6 for roof now I’m unsure Thanks great videos and excellent workmanship
Subbed 👍
I'm buidling a garage (bricks) 6mx14m, flat warm roof. What is your advise about the timber I should use?
Boss video
Great video! Have you built the front frame higher to start or achieved the extra 75mm with just the running timber added on top?
Hi, great video, thanks. I’ve just built a breeze block shed and now adding the roof. I’m an amateur at this and going to try it out. Does the wood need to be treated timber or can I use standard Wickes studwork CLS 38x89x3000?
You used joist hangers upside down over the steel, but just nails on the joists over timber wall? Is there another option there without a nail gun? Any other type of strap? Twist straps?
What's the distance between the 2"x5" rafters please?
what size timber would you use to fo a roof on a building 6.5 metres by 3.8
Hi Liam, excellent work. Do you plumb cut the ends or just leave them to go with the pitch of the roof? Thanks
Great videos will , Am I right in saying if I stand off 2m from the boundary I can have a vaulted ceiling with a total max height of 4m.???? wanting to do maximum permitted size of 5m x 6m thanks bud.
Hi Liam, need help planning a 4-car carport, 6m x 12 metres, going to use C24 4x4 posts every 3m, 15 in all, right decision? 30mm drop per metre, front posts 2.9m, back sticks 2.72m. May use slats for the side to allow some wind through. 2 x 5 timbers enough?
Great job!! Ever done one with a skylight? Is it worth the effort??
How much would it roughly cost for a 5m by 3m, I’ve got a job coming up and need to price it up but don’t have a clue where to start
Why do you use deep roof beams rather than just a normal 2x4 size? These videos are mint!
What timbers shall I use for a 4.3m span ?
Looking at your roof system which I like you don't cut a birds mouth notch out for roof joists is this the best /easiest way
Liam, Great Videos, does the 300mm overhang include the cladding or is it 300mm from the OSB to the front of the facing board, what length is your spacer?
Such good videos, thanks. What steel do you use? 3mm Rectangle box? 50mm x 125mm? And why do you use that rather than Sister'd wooden joists? Less flex presumably for the doors to fix against?
160mm x 80mm x 5mm, Id use two 5x2's but I like the fact Im the only one using a steel and I know it'll never flex
What about a slope ? Or is it not needed ?
