Single Storey Extension Stage 7 Cont. What comes next?

In this video I explain why I left the velux openings until this stage, I'll complete the ladder frame ready for brickwork cut ups and go through the complete 'how to' when it comes to setting out your lath for tile gauging

[@PaulRansonArt]

Brilliant video. You explain how to set out a job to perfection. Not many builders take the care you do with your jobs. Thank you.

[@Who.IS.my.daddy.]

I’m a carpenter by trade but I’ve never done a roof, always worked internally abd 2nd fix (bar in college 20 years ago!). Just about to start the pitched roof on my own extension and this has been a fantastic reminder/education. Thanks 🙏

I always run my wall plates through to the outside skin , then you have something to fix your barge board to . Love the videos that you both do you can see that you like the banter which is what keeps us builders sane . 😅👍🏻

[@Mr_A_Builders]

Hi Lee. If Im honest which we always are on the channel that was the first and last time I won’t run it all the way through it was a complete pain in the arse to fit my ladder frame rafter on my own without it there. Thanks for watching mate have a good week

Me too Always open to new ideas

[@oldtimer43]

I have to say I am really enjoying your videos, I just wish I was still making similar ones but I have run out of projects and my wife tells me I am too old to start another lol. I did build a 40 sq m extension to my bungalow single headedly 4 years ago at the age of 75 including hand digging 130 ton of soil/clay/concrete etc so I can't complain. I did make a video if anyone is interested or thinks they are too old to start such a thing. Anyway keep up the good work

[@Mr_A_Builders]

Cheers Michael I’m glad your enjoying our content and hope we can continue to keep you entertained.

[@Simon350S]

Have to say, I was brought to your channel by KZbin pushing your wonky patio/retaining wall video, and my initial thoughts were that you were a bit of a cowboy. I’ve watched this build progress and I’ve more and more come to realise that your standards are actually really high and I’m enjoying them. Completing a self build currently and building it to engineering rather than builder tolerances as it seemed finding someone to take the project on to a good standard was next to impossible after a proper dodgy cowboy starting it off so badly, along with countless bad experiences in other properties over the years.... Anyway, keep it up, really enjoying this now and the attention to detail is ticking all my boxes. 👍

[@duncanblanchard334]

Very interesting, but as a non builder person I’m wondering how strong the fixings are connecting the rafters to the house wall plate, is it only nails holding them in place. I’m not criticising but it just doesn’t seem strong enough to me to take the weight. Thanks for making this video 👍.

How are you fixing the wall plate onto the wall? Chemfix resin? Great video keep up the good work 👍

Quality How wide should you leave for velux/Dakea/key light

Have you boltod your double rafters were your velux are going and have you staggered nail them also

I'm about at this stage with my lean to extension roof. I have to construct a ladder at each end and made note that yo said you would use 120 x 6 screws. Are these screws special in any way? I have a supply of 100 x 6 stainless screws. The noggins will only be 200mm long for technical reasons. If you could reply I would greatly appreciate it. Thank you Have enjoyed watching your progress. Paul

[@Mr_A_Builders]

Hi Paul glad you enjoyed it. Can’t remember the exact reason for the 120mm screws if I’m honest. 😁 What you need to make sure is that once it’s all fixed together that the brick work is built up around it and supports it properly unless when the weight of the tiles go on it it can drop. 👍🏻

[@Yorkshirelad58]

@@Mr_A_Builders OK, I'm constructing ladders now. It will be a warm roof with zinc folded seam work above the insulation. I'm sure it won't weigh anything like tiles so I reckon I'm fine doing as I suggested. I have learned and been reassured massively by watching your progress. Thank you and your team. 👍

[@paulgilliland2992]

Mr A . Would you mind talking about budgeting costs for a similar sized build? I know people don’t like talking prices but it might help someone think before deciding to move forward with a major investment like this.

[@denty32]

Hi, why did you only put the ladder frame to one side????

[@Mr_A_Builders]

Morning Steve, hope you're well. It's easier to watch that explanation in another video of this series than it is to explain here. Apologies for the non answer answer!

[@amazing451]

Hi Rich and some great info on how to set out the laths in the video. The line your pointing to at 18.31 on the video, am I right in saying that this is the top edge of a lath and not a tile. Also at 8.07 on the video did you say where the kneeler's going, what did you mean by that?

[@Mr_A_Builders]

Hi Kev. The lines I would have pointed to would have been top of lath and the kneeler is the tile kneeler feature we did to match the house but you’ll see that in the next episode where Adam builds it 👍🏻

[@Davidlouis3]

Should have took your wall plate further to hold and support ladder section, there’s a risk of sagging on the corner once tiled, and should have extended main wall beam to fix ladder section on to and put wall starter underneath

[@Mr_A_Builders]

Hi David. There’s a block at the bottom on the brickwork supporting the barge board rafter, it’s nailed and screwed into each noggin which has been built underneath when we completed the brickwork cut up and I can’t disagree with extending the bolted plate cos I have always done that but didn’t this time cos I thought I try this way to allow me to run the wall starter up further. However The plumb cut of it is sat on a piece of plate section and tight to the wall so I’m happy I’ll get no sag. Thanks for watching 👍🏻

[@steverobinson9221]

Why don't you use truss shoes on the rafters at the house end to help take the weight of just the nails

[@Mr_A_Builders]

Not necessary Steve. The only way the nails will fail is if the rafter was to push the main wall over first. I could understood the thought process if this was a floor because of the vertical loading but it’s different when there are pitches involved. This method has been used for more years than I’ve been alive so who am I to change it. Thanks for watching 👍🏻

[@JBSeymour]

Why are your velux trimmers plumb and not square to rafters? 🤔

[@Mr_A_Builders]

Good morning. In the instructions of a roof window the bottom trimmer should go plumb and the top one go level. This aids the air flow around the window. However I don’t put the top one level as explained in the plasterboarding video later on because it’s a struggle to get it insulated and boarded properly so I put the top one plumb as well and trim in around it later. Hope this answers your question have a good day 👍🏻

[@leeberry9666]

What about solid bridging?

[@susanpritchard6164]

How do you price an extension is it about 2700 a square metre these days

[@Mr_A_Builders]

I generally price on material costs at the time and then how long it takes me to do certain tasks. Once I’ve worked it all out I will then generally have a look at what the price per square should be and then see where my quote sits in that. However, there are a lot of variables dependant on what your doing and where your doing it so the £PSM doesn’t always work 👍🏻

[@TH-cl5be]

so do you have to put a lat + the thickness of a tile on the 1st row to keep the tiles at the same profile or not.?

Hi Tim. If you watch the next episode it’ll show you why we won’t be putting a ladder frame either side. However, a ladder frame is needed for a barge board but on the other side we are running tiles over the brickwork and cutting the bricks to the line of the roof. Thanks for watching 👍🏻

[@swiftness2774]

Still no top birds mouth........the whole wait of the roof is being supported by the fixings, probably plasloade nails with the shear strength of a chocolate tooth pick. Using marley pan tiles adds a massive amount of weight at a guess about 1200kg. Velux windows 120kg x3. 1560kg all sitting on 3 nails per rafter nice.....

[@swiftness2774]

Double that weight when snows.

[@Mr_A_Builders]

It's not though, is it. If you, you know, actually think about it.

[@Who.IS.my.daddy.]

It doesn’t quite work like that 😂 unless the new extension block work can physically move outwards, for the timbers to move DOWN they have to also move out due to the angle they’re cut at. If hey were a flat roof with no hangers yes this is a valid point, but as it’s pitched the timber can’t physically move downwards without lengthening, which makes it TIGHTER, helping the fixing rather than hindering.

[@Mr_A_Builders]

Good lordy roo we've found someone who gets it!!! Haha! Cheers man, hope you're well.

[@swiftness2774]

There is no tie beam people which means the weight of the roof wants to push away from the existing building. Hence the top birds mouth which prevents this. Put a tie beam in and you wouldn't need a top birds mouth.

[@johnwright5086]

[@robertscott961]

I would have put the top lath level with the end of the rafter , your going to have a 50-60mm gap at the top that the lead will eventually settle in to , you could fill it with mortar...

[@Mr_A_Builders]

Hi Rob. Your correct in your assumption of what is now 40mm above tile to the wall gap but I used 300mm lead to dress down and it also sits on top of the abutment ventilation. That’ll be covered in two episodes time. Thanks for watching 👍🏻

[@jordy798]

I would recommend a good breathable membrane here, too many people buying cheap membranes thinking it'll be ok if I have fascia vents then abutment vents st the top but then your roof windows block any ventilation above and below them. Tyvec, Klober or Cromar be good choice as they require no additional ventilation
