Hi, my loft is the same, and we suffered from condensation in the winter and excessive heat in the summer. I have installed a total of 20 vents in my loft, 10 on the front and 10 on the back, and our loft has since been dry and considerablycolder in the summer.

I live in a newer property that has vents in the soffits and a dry ridge system. However, we still ended up with condensation and mould on the membrane, and it would appear that everyone else around us is in the same boat. I’ve just started to install these lap vents, but I wasn’t sure how to best place them. I’ve generally put two in each gap (one just up from the soffits, and another further up towards head height), then skipped a gap to do the next one. When completing the opposite side, I then did the same, but staggered them by one gap to prevent air coming in and going straight back out. My roof has three sides to it, so I’ll need about 35 vents at a cost of £90, but having 12 traditional tile vents was going to cost £900! Any help is welcome if I’ve not done this correctly. I’m going to re-do the loft hatch seal today.

Hi John, It sounds like you have installed them correctly. Not only do you require an airflow in the loft, but you need the air to circulate. By positioning them in alternate gaps between the rafters and not inline with the opposite side of the loft, you should achieve a dry loft. It sounds like you have installed them perfectly!

We have a property built in 1800s ,it has no plastic fascias, it has a breathable membrane and at the end of the loft space there is a metal vent . The loft is very small as it has been raised and the ceiling tongue and grooved to allow a bigger space in the room below. This means that where the roof begins is very close to the tongue and groove. Having been up on the lift for the first time I have noticed that fibreglass insulation is pushed down the thin gaps between the tongue and groom and membrane . The lift has a lot of condensation and damp. We have also had a couple of yellow looking water stains appear on the plaster board on two walls since winter arrived. Which I think is due to the insulation touching the membrane . I have had a local builder friend round and he has suggested replacing four of the roof tiles with vent tiles . Will this sort the issue?

Hi, firstly, if your property has a breathable membrane, then it's obviously been re-roofed at some point. Breathable membrane helps with condensation to a degree as it is semi permeable, but the key to reducing condensation is ventilation.

She had never had the issues with the watermarks on the walls. Prior to moving back in we replaced the wooden front door with a composite and the windows in the kitchen for double glazing. I also sealed the gaps In the tongue and groove ceiling and painted . I am thinking that this has contributed the damp problem in the loft space ? This is why I am hoping roof vents will help .

Hi, firstly, thanks for your comment. You need to install them on both sides of the roof, this allows air to enter and exit the loft/roof space. The other important thing is to not install the roof vents directly opposite each other. This creates a turbulent air flow through the loft/air space. If that helps, don't forget to give the video a thumbs up! Also they are on offer if you follow my linkamzn.to/3XXG0Rg

Really great video, well presented and almost exactly what I needed. I think it is the only video on youtube showing the staggered formation. I said almost as the only thing missing was how to stagger these felt lap vents on the other side of the roof space. Is it perpendicular to the staggered formation on the other side, but then again the middle might be straight opposite. Even the manthorpe's installation guide was not at all clear and did not mention staggering at all. I think Manthorpe's instructions said to put one at the eaves and one at the top, miss one rafter gap and do the same. On the opposite side they did not say anything and logically it should mean if on one side one has put them 1,3,5 on the other side 2,4,6 for example, but these are not staggered. Maybe an F1 wind tunnel experts are needed to calculate most optimal position, hahaha. Great video irrespective of my questions.

Hi, more molecules. Thanks for your comment and question! Firstly, by staggering the felt lap vents, it will create a varied air flow entering the loft. Now, on the opposite side of the loft, stagger the vents in a pattern that doesn't match the other side and put them as you say 1,3,5 and 2,4,6. You are trying to create a turbulent air flow within the loft and avoid the air entering and exiting too quickly. Hope that makes sense?

@@FixitwithFowler Many thanks indeed for the really quick reply. It makes sense to stagger them in a way that the air does not flow directly from one side to the other. I always thought that the air would flow along the membrane from the bottom to the top rather than towards the middle of the loft. I will have to see what staggered pattern I can achieve and if it removes the condensation problem in my loft. Many thanks again. I suspect if a pattern does not work, to modify it and see which one works.

Ok, so this video is designed to cure damp or heat in the loft by increasing ventilation. By increasing ventilation, you minimise any difference in temperature, which eliminates condensation and dampness. Normally, if damp is on an external wall, then i would suggest looking at the outside of the house for any tell tail signs of water ingress.

Didn’t work for us either. Bizarrely I found a solution, which improved the condensation problem. My loft was fully ventilated and was very cold. One day I decided to block some of the ventilation around the eaves and take out the plastic vents I fitted. Straight away the temperature in the loft increased and the condensation reduced. On very cold nights, I use a 240 W tubular heater to increase the temperature a little more and this pretty much stops the condensation. Of course a cost is involved here, but I estimate it to be less then £2 per day and I would happily pay much more to rid myself of the worry of condensation. I’m not saying this solution works for everyone, but it did work for me.

Hi, newer lofts have a breathable roofing membrane normally accompanied with vented eves and a vented ridge (top of roof space). Older lofts like the one in the video have none of that but some have vented sofits (outside near guttering) only if they have been retro fitted. These vents definitely help to create a vented loft space which will not only help with condensation in the winter but cool the loft in the summer.

Oh right! The vents are positioned on either side of the loft (slightly staggered and at different heights).

I have this problem with wet joists and a feeling of dampness in the loft of our Victorian semi. We had a re-roof 2 years ago using our old and new slate tiles, roof membrane etc. I installed 10 lap vents and this still hasn't solved the problem 3 weeks on. To be fair, it's been exceptionally cold with hardly any wind movement but a week ago we had a lot of wind and dry air. I would have thought that would have started the drying process but it seems to have got back to how it was, which I thought there would be no more build up of moisture due to the vents letting it escape. No leaks in the roof as such and all tiles look sound from outside. Feeling under the membrane in the worst areas the battens feel wet too. Should I fit more vents and give it longer ?

Hi Ian. Unfortunately, there are many different grades of roof membrane starting at £40 a roll up to £140 a roll for a fully breathable roofing membrane. Have you checked if the loft insulation is upto spec 300mm deep and clear of the eves? Also check if you have vented eves or sofits, as a new roof should have vented eves.
