Great video, excellent presentation. Love the music too. I’m a over the hill woman trying to tackle DIY projects by myself. Thanks for the clear explanations and speaking audibly.
I have just discovered this series of videos and you (Ali) should be very proud of what you have achieved. A great, simple to understand and realistic set of videos. Well done 👍
Thank you! I am looking forward to watching more of this series in preparation for redoing my flat roof. Nearly 50, female, btw. I appreciate your tips on how to do things efficiently as a solo worker.
I’m. 62 female stated building the shed/garden room when my husband died just to prove to myself it’s all possible. Best investment was a block and tackle, I have both a rope one and a chain one. Both were around the £100 mark. New but as with all things you may be able to find the engine block one second hand . The other investment is a sheet carrier, it a trolly for sheet material, I found that it’s not so much strength that holds me back but my height and therefore reach, lifting sheet a is possible but carrying it even with Ali’s rope trick was impossible as I didn’t have a long enough body! Good luck Gabrielle, go for it girl.
I'm a big fan of Keith's been watching him a bit now, but it as also been very interested in your video's too Ali can't wait to see the next video of the build, Oh and course Keith's video's as well you young guy's make it really interesting for us pensioner's take care now.
Your video was clearly what I was looking for as I am getting to within 90 days of low pitch roof construction of private residence..here in s.central fla..vapor barrier explained..I am now going to spend the necessary $ at home depot for you much appreciated works you presented
Nice to see someone doing things well without adding all the jargon, great explanation of your method, good method too, this is how I do a warm flat roof also.
You should deserve a medal for this amazing works. Surely this knowledge and experience after years of headaches of fixing idiotic roofers who doesn’t have a clue! Well done and keep the hard work
Keith sent me here too - had a great time watching the back-episodes and always looking forward to the next. Great work, especially since you're doing most of it solo.
Keep up the videos ali! Im doing a slight extension and new roof to my garage next month but will involve stud walls and 9x2 roofing so this has helped!
You may want to consider a suggestion. To save the problem with matching up the board size with the joist spacing I use tongue and groove OSB. It gives a stronger structure even If a space it 2mm to allow for thermal expansion.
Brilliant again Ali, loved it. It’s great to see the transformation after each episode. Really enjoying this, so keep up the good work and congratulations on the subs !! Regards Paul
Awesome build ! Great video ! Tnxs for sharing ! I've almost finished my build and while finishing the roof I picked up some ideas of your construction.
Ali, i'm 28. Coming to the end of a year of a full house renovation top to bottom and finally getting to move my workshop to the house. Currently have a very old and tired prefab garage that i'm replacing the asbestos roof with a full timber flat roof and it's been a bit of an engineering feat. I'm about to kick off and watching this series if quick succession has really helped reaffirm the plan I have is both correct (and safe) as well as realistic so I just wanted to drop you a quick thank you and say great work on both the build and the videos.
I've just watched the series up to here Ali, I am so impressed. It's not just clips of you sawing wood and hammering nails, it's you sharing your research on building regs, insulating tables, advice on lumber buying and much more. Not only that, your production... sound, camera and editing etc is top notch. So I thought I would make this comment -I know you didn't make channel for the money, but rather to share you experience to help others and lets be frank it's always great to have an appreciative audience for feed back and advice. Anyway, the comment is this - Are you aware that Amazon is scouting for good quality videos (they already have a few TH-cam channels on Amazon Prime) such as your series? I don't know how much of a return you'll get monitory wise, but if you get a wider audience, whats the harm? Make a few enquires, mean while, I'm off to join Ep 11, again, thanks for sharing 👍
Thanks for your comments Gordon! I've tried to make the videos as good as I can but still a bit embarrassed by the earlier videos heheh. I highly doubt Amazon Prime would want this series but hey, I'll check it out! Thanks for the tip 👍
@@G1V3Y Haha enjoy. You can take solace that they took a lot lot longer to make than they do to watch! I'm up to Part 16 and then there are a couple of 'extra' ones clarifying some topics I saw people having problems with :)
Ali Dymock That’s good to know that your dedicated and still putting in the hard work and effort and putting these so far great videos out and I’m a younger viewer only 16 so I’ll need to wait a while before I’m able to build something like this on my own sadly can’t wait for the day I could build something like this. And sorry for any spelling mistakes and grammar I’m dyslexic so isn’t the best
@@G1V3Y I've always thought that for a teenager to gain their own space and then have somewhere to live in their early 20s when saving for a house deposit, a garden room in your parents' house is ideal
Great videos. I'm planning a similar build and have found your videos invaluable, they have given me the confidence that I can complete my planned build. Looking forward to the next video.
Great video 👍🏻 only thing I would say is if you want to use GRP you want to use a 18mm P5 t&g flooring board as the top layer. 22mm if it’s a balcony. This eliminates the need for bandaging the osb boards on the joints prior to laying the chop strand matt. I would also use a 225mm double thread screw so they countersink into the boards. It’s nice to see people take care installing the vapour barrier too as this sometimes gets overlooked on sites. Keep up the good work Ali
Great advice here and I agree (I think I mention going with T&G for the roof in Part 16), i just did the best I could at the time with the knowledge I had. I think have thermal break helix screws would have been a good idea too. What thickness of OSB would you recommend for joists spaced 600mm apart - 22mm or will 18mm still suffice if it's not designed to be walked on after installation?
@@AliDymock if the area was used for any foot traffic it should be 22mm. A OSB board has a larger span of 600mm for joist where the P5 is 450mm. Personally I always do joists at 400mm centres anyway as it’s more suitable for plaster boarding on the inside ceiling and strengthening the roof to avoid the joists sagging over time causing pooling on the roof. Doing a warm roof is always a stronger option anyway so span gaps do not matter as much on the top layer providing the sub deck has been installed to the correctly to board specifications. When installing P5 boards for GRP you install them upside on the top layer. This makes the lower joint tight but leaves a 1-2mm gap on the top side allowing GRP resin to penetrate the joint to locking the boards together and creating a great key for the roof. Like I said before keep up the good work your videos are very helpful to people who may need help installing these roofs the right way. I see way to many times on what happens to poorly installed or incorrectly insulated roofs ! It’s very frustrating and costly to the customers. Thanks for taking the time to make the vids. 😁
Everything you have done in your videos I have done plenty of times before. Some I do slightly differently but what I found to be the best thing you did and something I haven't seen elsewhere, was to list plenty of UK regs and also the differences in styles or techniques. I have actually given your videos to a couple of clients and told them to watch as you explain this stuff in a easy to understand format and it saves me going through it with them :) It is also interesting to see your results with minimum / cheap tools rather than having the entire tool shop like the Americans tend to have. I look forward to seeing it finished although I don wonder what you will tackle (or have already tackled) next?
Wow that's great, I hope it's of use to your clients. I guess the most 'useful' video to look at options is Part 9. There's so many methods of building a garden room but I think the majority of my build will suit a novice. It's hard to know which order to do things but you'll find out soon enough which is the next task I took on 😉
Excellent - nice to have a variety of viewers! It's a good idea, once the project is done I'll do another playlist on setting up the workshop. I'm definitely thinking along the lines of french cleats for a lot of my tools :)
Another incredibly informative episode - I'm gripped :-) If I'm ever lucky enough to take on a project like this I'll be using this series as my step by step guide. Thanks for sharing such valuable knowledge and know how :-)
I don’t normally comment on things but thanks for all the help I’m thinking of building one for the kids and you’ve got the best videos I’ve found when’s the rest coming 👍🏼
Excellent series of videos mate hats off to you, I'm currently having a Buy v's Build debate with myself and this gives me a lot of food for thought :)
It's a tough choice for sure. I would say that if you enjoy the thought of building your own and generally doing DIY/using your hands then take it on, you'll get a better end product. If you value your time for other pursuits and have the money go for the buy. Hopefully these videos tell you all you need to know to build or ask the right questions if buying 👍
@@AliDymock I love the idea of building one and wish I'd started this process at the beginning of lockdown, hindsight is a wonderful thing. I don't think I could build one cheaper than I can buy one bizarrely and that's like for like spec wise, I'd want to upgrade a few things so all adds up 😏
nice vid! just to point out never cut the vapour barrier like you did. You must overlap over the insulation. Where you had the wood on top and the insulation in the middle you should of overlapped the wood back onto the insulation and taped it on. Then put in osb on top. Then around the edge put in the membrane if needed or upvc.
I vapour barriered across the roof joists before laying the sub deck, so I could glue the kingspan to the sub deck, then used 18mm Osb t&g boards, again glued to the insulation. So no need for the long screws or thermal bridge.
awesome Ali! Suggestion for your channel.. there’s so many that cover projects that are unique and creative but be great to see practical projects in the house.. just a thought. Great work.. tough foundation dig on mine.. found an out building under the soil at the back of my garden.. so getting to the subsoil has been a right pain but now it’s mortaring the blocks!
Yeh I think that will be the general direction of the channel, creating things and doing projects that I need doing whether that's furniture or renovating. Thanks for the idea. Cool! Just think-it's a great workout and you're being productive at the same time! Worth taking your time over the blocks, probably the most important part of the project!
another informative video. I have to admit i didn’t really understand youtube until i started watching your channel. I was of the opinion that it was all about funny animals, people watching people play video games or kids opening stuff. This series has been really informative, along with some of the other channels you recommended. thank you for the series. On the back of them, like one of the other posts, my foundation blocks are down and timber floor about to be constructed. The remaining question. warm or cold roof. Just can’t decide. Thanks Ali
haha I guess you'd be right but there's a plethora of other stuff out there. You might like April Wilkerson's channel-she's recently done a series on building a humungous workshop in Texas. Warm/cold roof is a toughy, you'll need to decide before you start the walls though!
One tip is to use stainless steel screws on top. I built a roof a few years back where the water got in. I didn’t notice until much later and all the screws rusted out and were a nightmare to remove
Cheers. In retrospect I reckon it could have been a bit better but I'm pretty happy with it. Yup, for an extension that seems to be the norm - usually bang a 25mm board on top of a 100mm one it seems. For a non b regs garden room - 100mm seems to be more than good enough. Law of diminishing returns means the cost for the extra 20/25mm doesn't get you an awful lot extra thermal resistance, plus adds another 25mm to the height!
@@postman445 The law of diminishing returns comes in to play. Between 80 and 100mm a difference of 0.04W/m2.K but between 100 and 120mm 0.03W/m2.K. It's very toasty in winter and more than enough for a garden room.
@@postman445 The U value is proportional to the thickness of insulation you use as well as thickness of the decking material; plus the type of insulation material; as they all differ in their respective Lamda value or resistivity! But it would a lot less than having 120mm of insulation!
It is only a warm roof if there is no decking on top of the insulation. The waterproofing membrane must be directly on top of the insulation, if not the decking is cold and not warm. Even some building inspectors don't know this.
Ali thank you ! Your videos have given me the confidence to build my own garden office. I'm currently well into my project and each of your clips have been an invaluable source of reference to guide me throughout. When is part 11 being posted ?????
Don't be mugged off people. 1000 gauge polythene is the same whether it is green, black or any other colour. The manufacturers will charge much more if it is called "vapour " barrier and is coloured green. It is the exact same product as the black.
What is the thinnest insulation you could get away with and it still keep the dew point above where it needs to be? I'm building a garden room that has to be 2.5m max so I want to go as low profile as possible. Thanks
I think even 25mm will do quite a bit, 50mm is a nice depth for warmth. If you're really struggling with height I'd go with a cold roof and go thick - 100mm+
@@AliDymock Thank you for taking the time to reply, it's most appreciated. I can get away with 50mm yes that would be okay. Yes the cold roof option is still on the table I just don't want to mess it up by not having sufficient ventilation and the warm roof seems a bit more foolproof ha. Thanks again.
@@GoExperimental the ventilation is pretty easy, depending on what you are planning, I’ve just done a cold roof on a 3x5m workshop, left overhangs on all four sides, although really front to back is the most important. I then clad the soffits of the overhangs with recycled pallet wood (although you could use any sort of wood) and left a couple of mm between them to allow airflow above the insulation :) Good luck with your project
Just been watching video where you are putting on the top osb. Is it necessary to you the long nails if you are laying/finishing with rubber roofing. Cheers
Thanks for another great video. We are building a cabin in our garden (for us to live in whilst we do our house renovation) and trying to do as much ourselves. We have got a builder to do the main construction. The builder has done a cold roof, but not put OSB boards on top. He has a membrane directly above the joists (where the insulation will be), the battens, then our metal roofing will go on top of that. Im a little confused as I thought you would always have boards on top of the roof, but I guess this way you solve the issue of ventilation/allowing vapour to escape? For peace of mind can you confirm you dont need OSB boards on top? Thanks so much!
Ithink this is what Ive been looking for. Thanks a lot. So it doesnt mess up your stats this isnt lilly its her Ddad I don't know how to change it . Like the tips especially the string to nail into rafters
Great series. Im taking the plunge myself. Quick q - in your design video it says you'll use plywood, but you went for OSB. Did you work out that OSB was strong enough etc?
Thanks for much useful advice! I'm wondering about finishing my roof with corrugated iron or similar - I'm guessing I could waterproof the top deck with a membrane of some kind and then fasten the corrugated iron to it - would that work?
It's clear you're not a pro (we have set methods common to us all but you do things a little differently) but having said, that, you are most definitely a natural! With over 33 years experience of carpentry and joinery behind me, I am utterly impressed and have learned from you! Thank you!

Surprisingly the UK sets the standard and all others follow suit. I learnt this at college whilst doing plumbing.
Nice to see someone doing things well without adding all the jargon, great explanation of your method, good method too, this is how I do a warm flat roof also.
One word mate “fantastic “
Watching this for some ideas fir reroofing my modelling shed 😊
Finally!
Waiting for next part was worse than waiting for another episode of Game of Thrones!
Great job Ali
I know, I'm super slow! My plan is to finish this series before GRRM finishes The Winds Of Winter though! 😋
Thanks for the latest update Ali. looking forward to seeing the next episodes and the eventual woodworking projects. Glad to see the new boots!
Haha the boots were well needed. Got them for my birthday. I'm looking forward to doing some proper woodworking too!
You should deserve a medal for this amazing works. Surely this knowledge and experience after years of headaches of fixing idiotic roofers who doesn’t have a clue! Well done and keep the hard work

Loving the series - can’t wait for the next instalment. Thanks Ali
You're very welcome Kevin, glad you enjoyed them :)
Amazing I have literallyonly just finished watching the previous video and was gutted that I had to wait for the next one. Brilliant!!
I subbed after finding you through my efforts of soundproofing. You gave me the confidence to undertake the project! Thanks!

Very good, detailed and informative video! Thanks a lot from Holland.
You're welcome, from England.
Just have the concrete slab laid for my garden room, will be following your videos closely from this point
Very detailed and nicely presented
Coming along very nicely and loved the top tip on carrying 8x4 sheets looking forward to watching part 11 another big thumbs up:)
Thank you Ali, You helped me build my dream. I have a static caravan with an extension. I used this series to help me. LOVE YOUT WORK MAN! RESPECT
Great video series.
works well and good qualitiful shed building guild
Cannot wait for your next video, using these as a template for building something smaller in my own back garden.
Ola amigo great content I’m about to attempt doing a a gym in my garden and I start learn a lot from you
I will be doing my self
Go for it!
Great job Ali. Thanks for sharing your experience.
Keep up the videos ali! Im doing a slight extension and new roof to my garage next month but will involve stud walls and 9x2 roofing so this has helped!
Great series, really helped me in my build, thanks
what an excellent video series, very well detailed and explained, thanks ali, will be building mine soon
Insulate the edges before OSB work I always find is best practice. good to see its not just any old plastic you are slapping down there.
I need to do a flat roof on a block extension great video
Great Video!! I love it!
You may want to consider a suggestion. To save the problem with matching up the board size with the joist spacing I use tongue and groove OSB. It gives a stronger structure even If a space it 2mm to allow for thermal expansion.

haha, I know. It's pretty much there, I'm just waiting on something first! Sorry!
I vapour barriered across the roof joists before laying the sub deck, so I could glue the kingspan to the sub deck, then used 18mm Osb t&g boards, again glued to the insulation.
So no need for the long screws or thermal bridge.
Nice! What kind of glue did you use Lee?
@@AliDymock I used Illbruck CT704 contact adhesive

Spirit level 😂
Ali brilliant video but not sure about music 😂👍🇬🇧 Great work.
heheh fair enough!
I know this video is some what out of date... BUT YOUR A BEAST to do the work by yourself. !!!! I APPLAUD !!!
Ha, thanks. Anyone can do it though!
I've watched these sssoooo many times it's a wonder I haven't squed the figures😁
Part 11 please! good job!
awesome Ali! Suggestion for your channel.. there’s so many that cover projects that are unique and creative but be great to see practical projects in the house.. just a thought. Great work.. tough foundation dig on mine.. found an out building under the soil at the back of my garden.. so getting to the subsoil has been a right pain but now it’s mortaring the blocks!
Yeh I think that will be the general direction of the channel, creating things and doing projects that I need doing whether that's furniture or renovating. Thanks for the idea.
Cool! Just think-it's a great workout and you're being productive at the same time! Worth taking your time over the blocks, probably the most important part of the project!
another informative video.
I have to admit i didn’t really understand youtube until i started watching your channel. I was of the opinion that it was all about funny animals, people watching people play video games or kids opening stuff.
This series has been really informative, along with some of the other channels you recommended. thank you for the series.
On the back of them, like one of the other posts, my foundation blocks are down and timber floor about to be constructed.
The remaining question. warm or cold roof. Just can’t decide.
Thanks Ali
haha I guess you'd be right but there's a plethora of other stuff out there. You might like April Wilkerson's channel-she's recently done a series on building a humungous workshop in Texas.
Warm/cold roof is a toughy, you'll need to decide before you start the walls though!
If I lived nearer I would have gladly helped you with the lifting as I always seem to work on my own so know how you feel.Tim
One tip is to use stainless steel screws on top. I built a roof a few years back where the water got in. I didn’t notice until much later and all the screws rusted out and were a nightmare to remove
Even though they're under a roofing membrane?
Ali Dymock absolutely. If the membrane fails or damp gets in somewhere else trying to remove rusted out screws is a PITA
You're the only person I've seen who actually does a warm deck correct! however the minimum thickness of insulation for a warm deck should be 120mm
Cheers. In retrospect I reckon it could have been a bit better but I'm pretty happy with it. Yup, for an extension that seems to be the norm - usually bang a 25mm board on top of a 100mm one it seems. For a non b regs garden room - 100mm seems to be more than good enough. Law of diminishing returns means the cost for the extra 20/25mm doesn't get you an awful lot extra thermal resistance, plus adds another 25mm to the height!
Ripper36068 how poor will the insulation be if 100mm is used instead of 120
@@postman445 The law of diminishing returns comes in to play. Between 80 and 100mm a difference of 0.04W/m2.K but between 100 and 120mm 0.03W/m2.K.
It's very toasty in winter and more than enough for a garden room.
@@postman445 The U value is proportional to the thickness of insulation you use as well as thickness of the decking material; plus the type of insulation material; as they all differ in their respective Lamda value or resistivity! But it would a lot less than having 120mm of insulation!
New boots!
Stagger seams in the kingspan also
It is only a warm roof if there is no decking on top of the insulation. The waterproofing membrane must be directly on top of the insulation, if not the decking is cold and not warm. Even some building inspectors don't know this.
Also vpc should lap up the sides of the insulation around perimeter
Good suggestion 👍
What about the furrings for the fall?
Nice one geezer :)
Ali thank you !
Your videos have given me the confidence to build my own garden office.
I'm currently well into my project and each of your clips have been an invaluable source of reference to guide me throughout.
When is part 11 being posted ?????
That's great :) Part 11- this week!
Don't be mugged off people. 1000 gauge polythene is the same whether it is green, black or any other colour. The manufacturers will charge much more if it is called "vapour " barrier and is coloured green. It is the exact same product as the black.
What is the thinnest insulation you could get away with and it still keep the dew point above where it needs to be? I'm building a garden room that has to be 2.5m max so I want to go as low profile as possible. Thanks
I think even 25mm will do quite a bit, 50mm is a nice depth for warmth. If you're really struggling with height I'd go with a cold roof and go thick - 100mm+
@@AliDymock Thank you for taking the time to reply, it's most appreciated. I can get away with 50mm yes that would be okay. Yes the cold roof option is still on the table I just don't want to mess it up by not having sufficient ventilation and the warm roof seems a bit more foolproof ha. Thanks again.
@@GoExperimental the ventilation is pretty easy, depending on what you are planning, I’ve just done a cold roof on a 3x5m workshop, left overhangs on all four sides, although really front to back is the most important. I then clad the soffits of the overhangs with recycled pallet wood (although you could use any sort of wood) and left a couple of mm between them to allow airflow above the insulation :)
Good luck with your project
@@matthewsaunby9056 Thanks for the advice, Matthew. I'll give it some more thought. Cheers
Go Experimental nn
Just been watching video where you are putting on the top osb. Is it necessary to you the long nails if you are laying/finishing with rubber roofing. Cheers
Would sips panels be a better option for a warm roof ?
Thanks for another great video. We are building a cabin in our garden (for us to live in whilst we do our house renovation) and trying to do as much ourselves. We have got a builder to do the main construction. The builder has done a cold roof, but not put OSB boards on top. He has a membrane directly above the joists (where the insulation will be), the battens, then our metal roofing will go on top of that. Im a little confused as I thought you would always have boards on top of the roof, but I guess this way you solve the issue of ventilation/allowing vapour to escape? For peace of mind can you confirm you dont need OSB boards on top? Thanks so much!
Ithink this is what Ive been looking for. Thanks a lot. So it doesnt mess up your stats this isnt lilly its her Ddad I don't know how to change it . Like the tips especially the string to nail into rafters
Lilly - tell your dad to get his own google account 😂
This guy is a dope!
you mean IS DOPE, surely!?
For me the last osb layer is not mandatory at all. Just add the metal sheets on top of the xps.
Great series. Im taking the plunge myself. Quick q - in your design video it says you'll use plywood, but you went for OSB. Did you work out that OSB was strong enough etc?
Thanks for much useful advice! I'm wondering about finishing my roof with corrugated iron or similar - I'm guessing I could waterproof the top deck with a membrane of some kind and then fasten the corrugated iron to it - would that work?
