Absolutely fantastic build and for those commenting that its like an 80s build when compared to modern methods....well can i suggest that they watch plenty youtube vids showing horrendous issues with modern methods. The breather membrane is current and long lasting so while its dangling into the gutter it will last a long time say 15 to 20 yrs and after that if does rot then that part section can easily be replaced by slightly lifting the bottom tiles and sticking more membrane or even a drip tray if you like. Well done you've got a new subscriber here. Having worked on building sites for many years, I can assure people that theres a lot of uneducated and even criminals doing awful standard work just for the money. They dont take pride in the work that they do. I was accused more than once about being pleased with my work. In fact one awful ex boss who often put me down was caught thieving materials and accused of show boating only when the customer was on site!!!

Love it. Bout a house a year ago, didn't realize it was guna be so much of a doer-uper. One of the last things I'd like to do is replace the conservatory roof. I was thinking of going for a OSB boar and liquid rubber system on top. Your video has given me food for thought. Thanks for putting this vid together. Very helpful. Dan 👍👏👏👏

You need to double up the timbers for the velux Windows mate

[@aaanton11]

Thats an interesting point, with my calculations the amount of joists I used and the thickness and the length, pitch of the roof I have more than enough support for the weight of the tiles and 1m of ice if we have a really bad winter 🥶 Thanks for the great comments👍🏻👍🏻🛠

[@labbo5591]

Should have doubled those joists either side of the velux opennings!!! This is why we have building regs to prevent people buying dangerous bodge jobs!!!🤯🤯🤯🤯

[@edthompson9337]

You cut way too much out on the birds mouth cut (front cut out over door), maximum 1/3 depth of rafter, you effectively reduced the size of timber you used!

[@aaanton11]

I needed the extra cut to get the pitch right, don't worry I fixed with extra screws right through the thicker sections for extra strength Thanks for the great comments👍🏻👍🏻🛠

[@edthompson9337]

@@aaanton11 Additional fixings would make no difference, the underside of the rafter is not bearing on the timber wallplate therefore reducing it's strength. That along with not doubling up the rafters either side of the roof windows means it would not comply with UK building regs. It's a good effort for an amateur but ultimately flawed.

[@AlexGnok]

exactly what I thought when watching this - so much thickness of the rafter is wasted. You almost reduced the rafter to something like 2x3. Amount of fixings doesn't matter as timber can just split

[@mikebarry229]

@@edthompson9337 In this case the single rafters were probably JUST about OK, but 100% that degree of notching is not permitted, and additional screws wouldn't generally be accepted, instead multi nail joist hangers could have been fitted to provide the additional bearing required.

[@daves4026]

Aren’t the side spars to the Velux windows supposed to be doubled up and the tops and bottoms as well?

[@aaanton11]

Depend on how thick the joists are, Thanks for the great comments👍🏻👍🏻🛠

[@mikebarry229]

As a general rule of thumb yes, doubles are often required each side. A simple way to look at it is the rafter size required without rooflights. If your roof needed 145x47 rafters at 400c/c's then yes you would need doubles each side (because you need to make up for the rafters being removed where the rooflight is). In this case it looks the span is about 2.8m and 120x47 C24 rafters at 400mm centers would have been adequate as rafters, but those would definitely have needed doubles around the roof light. 145x47 rafters in C24 grade being slightly deeper (and therefore stronger) would probably work as singles in this particular case, JUST. Very often doubles aren't needed top and bottom as the spans are so short (unless you have an extremely wide roof light). Contrary to some suggestions here, this work requires Building Regulation approval so the Building control surveyor will make sure that appropriate rafter and trimmer sizes are used. Building control surveyors will typically ask for doubles (at least initially) regardless of whether it is actually needed structurally as it is a good habit to get into.

[@johnbrown3471]

The pitch can be as low as 11degrees with certain makes of tiles. This is not so that rain water rolls down but to ensure water cannot blow back up the tiles.

[@aaanton11]

[@KingstonHomeMaintenance]

What degree pitch did you say? 17⁰ For that span if approx 3150mm you would need a rise of 963mm at the wall, which is nearly 13 course of bricks. Have you also notified building regs, as the conservatory is no longer and seems for to be akin of an extension plus that new roof construction has to be passed. Looks like about 8 course or 600mm.

[@aaanton11]

Yes all is inspected and the pitch is correct, Thanks for the great information👍🏻👍🏻🛠

[@davidowen1074]

Get rid of the trim and put dry verge on there 👍

[@worldofrandometry6912]

Just had my house re-roofed and they put sheets of OSB on the rafters, then the membrane, lathes and tiles. Maybe the OSB sheets are a local regulation. Good job anyway!

[@aaanton11]

It depends what was underneath, Thanks for the great comments👍🏻👍🏻🛠

[@mikebarry229]

Not a requirement in the England and Wales, in fact you wouldn't be allowed to do it like that as the membrane would be pinched between the lathes and OSB, trapping any water that got through the tiles. If you wanted to use OSB under the membrane you would need to add vertical battens in line with the joists on top of the OSB, then drape the breathable membrane over those battens, then fix the lathes over that. Alternatively the vertical battens can go over the membrane, but not as good in my opinion.

[@worldofrandometry6912]

@@mikebarry229 Yes, there are battens under the lathes. The original roof (built in 1975) had sheets of what looked like plasterboard on the rafters with felt over the top of that. All new roofs around here now have OSB sheeting.

[@mzd9219]

That's absolutely amazing and exactly what I need to do as well. Would you be willing to share any regs regarding roof replacement on existing conservatory (pitch, hight etc) thank you

[@aaanton11]

This roof had planning permission so the height wasn't an issue, Thanks for the great comments👍🏻👍🏻🛠

[@mikebarry229]

A conservatory of this size is exempt under the building regulations, but as soon as you put a solid roof on those exemptions no longer apply. Its a bit of a grey area but most Building Control bodies will allow the roof to be changed to solid so long as all the original external doors and windows remain between the house and former conservatory. A roof like this adds considerable weight and the council would be within their rights to ask for better foundations if the existing ones weren't adequate. A lot of companies that specialise on this type of work put lightweight roofs on instead that look like tiles or slate but don't add much extra weight over what was originally there. Another thing to bear in mind is how the roof will be insulated. 145mm deep rafters are not deep enough to get the required amount of insulation between (and leave a gap over) so additional insulation will be required under the rafters as well. Regarding pitch that is down to the tiles used and the minimum pitch for any rooflights. Some concrete tiles go as low as 10 degrees. Many tiles of the style shown here can go as low as 17.5 degrees unless they are sand faced (couldn't make out from the video clearly if these were) in which case the minimum pitch is usually around 25 degrees. It is a pain but all such tiles now have to be fixed at least once and two fixings around the perimeter. Planning permission is usually not required if the conservatory/extension is under 3m deep (or 4m if detached house) and certain other requirements are met around eaves and ridge heights. Check the Planning Portal for more info)

Windows wont weigh more than roof covering so cant see why you'd double up timber? Cutting a rafter to fit window of course need to strengthen but not for new roof with plenty supports.
