In part 2 I fit the lower deck layer and then build the curbs/upstands that the roof lights will sit on, before fitting the vapour membrane, insulation, top deck and fascia.
Hey Del, I left England in February 1978 because of these cold early morning starts in the UK - Snow, frost, cold wind and rain, I couldn't stand it, I hated it, I can still remember the ice cold feeling in my hands. I'm now in Melbourne Australia and you can' t beat it ! Apart from the Pub's of course, I hate Aussie Pub's
Hi Alan🖐Sounds amazing bud🤩The pub culture is not what it was when you left, and people just don't go in them as much nowadays😩Thanks for your comment 😎 Cheers Del
Again you teach a lot....I loved the idea of shimming up the center area behind the up stands so the don't pool water...SOOOOO many lads wouldn't bother with that detail I'd venture to guess. Great attention to detail..
Thanks for your great comment Brendan🤗Packing up a little behind the upstands is only a small detail, but as you say, helps prevent pooling which is not good for this type of roof covering👍Cheers Del
You're not wrong Mat, and you always think, 'it's only a little flat roof' and always is more involved than you think🤔Thanks for watching and your comment 😎 Cheers Del
I hope so too Trevor 🙏 The UK's construction workforce is getting older, and in need of keen, motivated youngsters👍Thanks for your comment 😎 Cheers Del
Back at it full on . Working at that speed means you had no time to freeze. Well done . Just remember once your watertight. Inside work. Cold hands warm heart. Take care
Hi Tim🖐I was only down to do the roof on this one bud, but I have been outside over the last week and the weather has been very kind🤞Thanks for watching🤩Cheers
Fantastic work as per usual big man, you can clearly see you have payed attention to detail very nicely done, planned and executed to perfection. 🔥🔥👍👍🤜🤜
Built a warm roof this week that is having a corniche style lantern, the roofer requested that we remove the upstands to make it easier to apply the rubber so that he doesn't need to join it. Never before been asked to build a roof around the roof covering. Lovely job there mate👍
Great attention to detail as usual. Even down to the 1 degree cut on the bottom of the dwarf walls. 2nd fix quality on 1st fix there Del. True of all your jobs is the planning and thought that goes into them. The considered methodical way that you work. The end result is then a testament to the pride you take in your work. I have never been as good a Carpenter as you. But have always worked with a phrase in my mind. Would I be happy with this work/product. If someone was doing it for me. Consequently I have pulled a few things apart over the years because the answer in my head was no. The photo of the end result looked great. It looked like a hot pitch mineral finish. Are they still doing that. Or is there a cold lay version now. That was another job I used to do back in the UK. I would have done the hot pitch work after building it. That would have been a 4 layer system all poured. Perforated layer. Thin layer. Thick layer. Then mineral layer. With a lot of mineral drip work. All the fronts done overhand with a hot mop. Jack of all master of none.
Hi Dave🖐Just like you, my default position on my work is, would I be happy if I was doing it for myself🤔I was also surprised to see this roof done with a the 3 layer, torch on felt system, but it comes with a 25 year guarantee, so it must be much better stuff than when I started 36 years ago, when its was exactly as you describe😮thanks for watching bud, and your great comment😎Cheers
@@thetallcarpenter Torch on. That makes sense. Couldn't see the safety police letting people run around with hot pitch anymore. Pitch pot fires were fairly common. And burns to the operatives also common. The odd house succumbed in the process. We used to watch the smoke. White good. Brown, here she goes. Torch on still looks the part.
Great job Del. A lot of work gone into this roof. Do you ever sandwich 2no 75x44s together and ply face instead of a single 150x44 perimeter upstands. Saves using a 200mm long fixing. The extra work behind the glazed panels to create a run off fall is often neglected. First class workmanship 👍
Hi Sean🖐I wouldn't say I have a set method for doing flat roofs as they are all different and I don't do many😶but if I needed to, yes, I'd happily fix 2 75mm timbers together to get the right make up👊That's for another great comment bud😎Cheers Del
Del great video , I’m writing this from my hospital bed after being on a roof just like that , slipping /tripping not sure which and going through the skylight opening , all happened in the blink of an eye . I’m not posting to criticise, just to say to everyone be aware , I have been cutting up roofs for 40 years and am confident in my abilities on timber , I did not expect to be taking a trip in an ambulance when I pulled on my tool belt in the morning . Brilliant video as usual
Hi Chris🖐 Sorry to hear you're in hospital bud, and you're right to point out that years of experience and the feeling of sure-footedness it brings, is still no guarantee against having an accident😬and those rooflight openings were a potential accident. Thanks for watching and hope you mend quickly🤞Cheers
@@thetallcarpenter thanks Del , and I meant the comment in the right way , we have to look out for each other , i shall treat myself to a new pencil when I get back to work 😀
Similar to what ime doing only ours are lanterns so we build them of the joists, we are having to build the upstands with 6x2 to satisfy the new regs to accommodate the insulation needed now,on the front we just plant a piece of 9x2 ripped down to the height for an upstand to fix the facia to.
Hi Andy🖐Yeah, these upstanding will need installation in-between the studs and Celotex over the front/inside🙄Thanks for watching fella and have a good week👍Cheers
I've tried several times to train youngsters but they just messed me about and spent most of the time looking at their phones😩 I've given up with trying to pass on my knowledge that way, which is why I'm posting videos on RU-vid👍Thanks for your comment 😎 Cheers Del
No real reason to do that way round, other than it's easier to construct and fit the curb/rooflight frames off the OSB deck rather than the open joists👍Thanks for watching 😎 Cheers Del
Hi have you got any pictures of the finished roof? i'd like to see the detail where the flat roof passes the pitched roof, does the flat roof protrude above the pitched roof? Cheers, great videos by the way
Hi Sean🖐 I haven't got any pictures of that detail unfortunately, but the roofer basically made a lead saddle and dressed it over where the 2 roofs met👍 It looked a lot better than I thought it would👌Cheers Del
6x2 or other size (depends on insulation thickness) upstand should be fixed all around perimeter on the of 18mm OSB - best T&G. Vapour control layer should go on the OSB and up on upstands inside. Insulation - Kingspan TR27 or other suitable for warm roofs cut tight and then mechanically fixed with thermally broken screws. DO NOT USE ANOTHER LAYER OF OSB ON TOP - IT WILL ROT! Finish with a final layer of waterproof membrane like EPDM, Sarnafil direct on insulation. Bitumen based waterproofing systems will require suitable underlayers.
Hi Del, did you have to use the 200mm long screws to secure the 150mm timber in front of the celotex ? It looked a great job at the end, and the builder got his money worths out of you on this one 👏 👏👏
Hi Kevin🖐Yes, I used 200mm screws to fix down the 150mm timbers into the toe end detail of the joists👍It worked really well actually👊Thanks for watching as always bud🤩Cheers
Hey Del, I'm doing my first flat roof. Do you know if the kerb edges are necessary for EPDM Resitrix? Not sure whether should I use it around the perimeter only where the roof meets the masonry or around the skylight upstand as well. Any thoughts would be much appreciated. Thanks!
Hi there🖐I'm sure about the exact build up and use of edgings for the Resitrix system as I've never used it😬Sorry I can't be of much help on this one😔Thanks for watching 😎
Hi Clint🖐I would go for the Paslode🤔It's only a little more but is a little lighter and more agile in tight spaces especially when skew/toe nailing studs, rafters and noggins. The Fischer does seem more reliable though, and it never misfiresd once during the freezing temperatures🥶 (that's comparing it to the IM350+ not the i series, newer Paslode👍). Cheers
another excellent video del..why the 5 deg is it because the flat roof pitch is 5 or do u make the upstand 5 degrees regardless of the roof pitch ..cheers
@@thetallcarpenter just spent weeks chipping and stripping 11 layers of felt and bitumen off a roof. Seems sad to disrespect great carpentry with an awful top layer. What were they thinking?
Hi Andy🖐The Fischer hasn't missed a SINGLE shot bud, but I definitely it a bit bulky/awkward to get into tight spaces, and I'd like it to sink nails a bit further in when skew nailing🤔It's cold weather performance is excellent👊Cheers Del
Hi Carlos🖐I marked the position of the joists on the brickwork of the main house and also at the outer edges, and then pinged a chalkline between these two points to give me the position of each joist👍Cheers Del
Nice to see a vapour barrier being used! Does T look like 150mm insulation added to the skylight upstands though? Warm roof’s definitely the way to go if you got the build height available.
Hi there🖐Its doesn't look like the curb is 150mm above the finished roof because the tilt fillet was 100mm x 100mm and the roof lights have a big skirt on them🤔I had to double check it myself when I saw it finished😵In my opinion, you must use a vapour barrier of you can get in a world of pain with sweating if moist air can get in from underneath😩Thanks for your comment and for watching😎Cheers Del
nice job . i am confused from watching the previous video where you applied the furring strips was that to make the roof flat .i understand you raise it slightly behind the lanterns but does the roof have a pitch and say if it did have a pitch could you build you lantern up-stands at 90. hope i am making sense , thanks for sharing
Hi David🖐As Rodger said below, the firings I cut formed a 1:40 fall or about 1.4 degree pitch. Cutting the bottom of the curb studs at 1.4 degrees means the they will be plumb and at 90 degrees to the underside of the joists👍Thanks for your comment😎Cheers Del
According to my builder because he is using the brand unilin 1500mm celotex insulation, he doesn’t need a vapour barrier under the insulation on a warm flat roof. Is this true?
Hi Tay🖐I have heard of people not using a vapour barrier, and instead relying on the rigid insulations silver foil layer🤔As long as its an approved spec and prevents the upwards passage of moisture, it will be fine👍Cheers Del
@TigerK94 Hi there. To be fair to your builders, you should really be asking them if you have concerns about the make up of the roof they have done for you🤔 I know from conversation with my Building Control Officer, that the foil on PIR insulation CAN act as a vapour barrier👍
@thetallcarpenter unfortunately my builder told me to go find out rather than help me understand. Building Controls officer also doesn't know and ask I find out if its correct and get manufacturer details .. not sure its my job to do that but its my house so I'm trying to get the information which I'm finding difficult to find /understand
Leaves a horrible detail at either end where it meets with existing roof. I am not a big fan of roof windows they are really heavy to get onto roof. You can't fit the same insulation or airflow as roof and the plasterboard finishes up against the glass on internal side. I fit a upvc corner strip but looks crap and hard to paint to. Be interested to know your thoughts or ideas.
@Paul Lindsay I agree with all you've said Paul🤔 The also condensate like mad which is why the roof covering MUST come up and over onto the top of the curb. Even if you get a nice idea to finish off the plasterboard at the top, you can still see its reflection in the glass for below😶 I'm my opinion, if you're going to have roof lights, I'd go for much bigger ones, and probably lantern type👍
@@thetallcarpenter agree 100% I don't understand why the frame isn't wider so the thermo board meets the frame instead of glass terrible design. I like the warm roof great way of top insulation.
Del sorry to be a pain. I’m going slightly off topic here. You’ve got a Makita palm router. I’m after some guide bushes for mine and I’m after some advise. Have you any suggestions to a decent starter kit as I’m only at DIY level not a pro. Any input would be greatly received. Diesel👍
@@darrenbethell3171 I bought the plunge base as you can fit different size collars in it, but I also bought a screw in brass guide bush to use with the trimmer base, but didn't like the fact the blade couldn't be easily raised out of the cut when completed and risked snagging the work😬
I’ve also got the plunge Base as well there’s just so many to choose from. Like I said I really need to get something bought as I’ve got plenty of Projects coming up that’s going to be using a lot of jigs for the router.
@Darren Bethell From memory I've got a 16mm guide bush for my hinge jig, and a 30mm one for something else that I can't remember🤯 The jig you want to use will usually tell you what size bush it needs, but failing that, if you're making your own jigs and guides, a 30mm bush gives you more flexibility for cutter choice👊
@Mac Smith What issues will arise from using screws to fix the top deck layer down through the insulation, through the bottom deck and into the joists?
@@TheToolnut Hi TN🖐Hope all is well with you🤞Yeah, I get that 'technically' the long screw canbact as a thermal bridge, but in reality, heat loss through the long screws would be almost unmeasurable 😉Cheers Del
Once you put timber deck over insulation it is no longer a warm roof . waterproofingg the should go over insulation simple .im wrong? check it out that roof will be full of moisture in a few years bollocked .take enough off so i know that roof will sweat like a pig . Warm roof --insullation above deck not above deck then cover it in osb !!! Take a look at warm roof construction see for yourselves
Looking for some advice anyone recommend me to treat new unglazed internal doors which treatment is the best and should I only treat the sides or the complete door ???
Hi There a hollow door and primed and ready to paint I live in a old cottage but I’ve been told to treat the ends to stop them from warping. And thank you for taking time to reply 👍
Hi Del, does the fascia go right to the top level with the top deck of Osb on the sides too? Or does it carry on to the tilt fillet on the sides? Thanks
Is the tilt fillet also called an aris rail? I can’t find it in wickes. Do you mind linking it so I can see what it looks like and what size did you use please Del 🤲🏼
@thetallcarpenter felt underlay should be laid on the insulation and the correct insulation for the underlay used. If it's torch on underlay, then a torch on board should be used like a power deck u. By putting the ply on top of the insulation, you have then used a 200mm screw and put a load of holes in the vcl, which is not the best way of doing things. Have a look at bauder, langley, icopal, and garland, all felt manufacturers, and not one is doing this. A lot of domestic flat roofs are being done like this now tho and it's not the best way. You should have used the ply to deck the roof out. Then the roofer would install a VCL glue down his insulation and then install one underlay and one cap sheet. You then have three independent waterproof layers as well.
@user-ol8jh6ji4u What problems do you see occurring due to the top layer of ply/osb being used and fixed down through the insulation and VCL, and why do you think that there is still so much information suggesting this detail🤔
@thetallcarpenter peppering the VCL with holes when it's not needed and losing a waterproof layer, extra and unnecessary weight load on the roof. The extra cost on plywood/OSB which isn't necessary. Metal screws as well may not help with any condensation issues down the line. Why the information is saying this on domestic properties only, is ridiculous. I'm thinking it's because builders doing the work are just using the 8ftx4ft foil back boards and thinking you can't install felt directly on them. (Which you can)
@@user-ol8jh6ji4u I am in full agreement with you that there are superior ways to construct a warm flat roof. In my experience, the build up method I showed in my video is not 'inferior' in terms of its ability to keep the room below both warm and dry for the life of the roof, but as you say, how a builder chooses to do a warm flat roof may not be the same as how a roofer does👍I appreciate your comments on this😎Cheers Del
I hear you Jo🤔but I get a lot of people contact me that are training/learning who say my explanations of what I'm doing are really helpful. Its always hard trying to strike a balance and knowing exactly what to show and/or say😬Thanks for watching though👍Cheers Del
Hi Del, thinking of the drip former. What size would you recommend I use? My warm flat roof is 8.5 x 4m and I am using 18mm ply, vcl,120mm insulation. All sitting above the joists which is on top of a single brick wall. It’s going to have a very tall Fascia.
The roof guys usually use 2x2 for the edge bead, which enables the roof covering to fall over the gutter👍And yes, flat roofs tend to have a tall fascia if you just sit the joists on top of the brickwork😬
