Find the full series playlist here: Part 10 of a video series about how to self-build a timber-framed garden room office (aka tiny house) /wood workshop in the UK. This video covers how I built the warm roof. The purpose of this video series is to provide all the information required for viewers to build their own garden room rather than just a montage of the building work. It took me months of research to learn everything in these videos so I hope to save people time and money. The videos are a mix of theory and footage of the build including all the mistakes I made along the way. I am not a builder or tradesman, just a keen DIY-er with some basic tools. Everyone can do this! In the longer term, I hope to turn this channel into a community for garden room self-builders and to eventually evolve into a woodworking projects channel – the real purpose of my garden room! Garden room ideas: workshop, office, games room, cinema room, art studio, music studio, yoga retreat, spare bedroom, annexe or run a home business such as yoga classes or hair salon. 🌍My website – 📸Instagram – 💌 Email – Tools used: Rope Circular saw Impact driver: Hammer Tape measure: Pencil String line Ladders Tarpaulin Spirit level as a straight edge Sharpie pen Safety: gloves, eye-wear, ear protection, dust mask Materials used: 18mm OSB3 11mm OSB3 Screws 50mm Nails 50mm 100mm timber Polythene vapour barrier:—2-5-x-20m/p/153230 Polythene tape: PIR insulation 180mm slab nails: Rag ‘n’ Bone Brown youtube channel: Good websites to check prices for materials : Music: Video Rating: / 5 Related PostsGarden Room Workshop: Part 9.

    How much did all thins cost in the end? I’m going to build a wood shop myself and I’m trying to figure cost of all the materials. Thanks!

    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.

    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?

    I have you to thank for my summer house. Cheers

    Great video, thanks. Do you think 11mm osb top and bottom would have been sufficient, as opposed to 18mm and 11mm? Many thanks

    Ali – quick question for you. At 5:50 in this video why is it that these pieces of timber aren't flush? The top one looks like the 2×4 boundary holding the PIR in place, but what is the lower timer? Is it the fascia board? Thanks!

  • Alex Ramsay 2 months ago

    Great videos and really useful presentation, many thanks. One thing I'm not clear about, though – if I were to leave the roof joists exposed internally with ceiling, deck etc above them, how are the gaps between each joist above front and back walls filled in? Have I missed something obvious?

    This is brillient. Excellent details. Was 100mm insulation enough to get the Building Control certificate ? (I assume you applied for one)

    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.

    Brilliant !! well done, if i can just say never walk backwards on a roof.

  • Fishamble 2 months ago

    Love the videos. Thanks.
    Do you really need to leave a 3mm expansion gap for OSB?
    I'm a DIYer and decked out my attic for storage last year. Didnt think I would need to leave a gap.

    I know this video is old now but i was wondering if the slab nails gave you any issues with the rubber roof. I was thinking of using a spade drill bit to recess them but not sure if the nail head also sticks up. What are your thoughts?
