Vents or existing flashings?

Door Conversions

I notice a few similar looking flashings close to the ridge. Are they for venting or simply an existing flashing you had to work around?

I believe the vents you are referring to are exhaust vents for attic ventilation. These particular vents are O'hagin vents (I attached a picture for reference). There are many ways to ventilate an attic, but each way will naturally have a "best application." For this particular homeowner, the vents we suggested were passive, using natural convection (heat and moisture rising) by pulling air in from under the overhang, and required no wind assistance.

Get a decent de-humidifier/air purifier... Run it for a few hours each day (placed on hall/landing for example) and it will clear up. Also, get a humidity monitor/sensor and keep an eye on things... Also, do you have a decent extractor fan in your bathroom? We had mold and fitting a decent extractor in bathroom plus getting a decent dehumidier/air purifier sorted it out (note our damp only started after an upgrade to windows, also note we have vents in walls too, they didnt help!)

Hi @J Lo no we haven’t bothered (yet). Generally its been fine. There’s no escaping the fact the long feed does create a bit of unavoidable condensation but it’s nothing major and easily manageable with some workaround measures. I got some cooker hood filters and cut them to size to lay on top of the cooker hood to trap the grease and smells more. i also fold a piece of kitchen paper into a square and put that underneath the motor of the fan so if there are any drips through where the motor unit is screwed together (that is the main culprit!) its well absorbed. The filter lasts about 3 months before I change it. The kitchen paper I change every couple of weeks and just to stress its a tiny greasy drip each time that dries up. I just change it for cleanliness when I check it and wipe the side of the fans, as I would anyway even without that issue. The way I see it is it’s still a much better set up than relying on a recirculating hood that doesn’t take the smells or grease outside at all. So the very minor condensation issue is a small price to pay. I was a bit obsessed with it when I posted on here but don’t give it too much thought now… until you posted and reminded me haha! I would suggest though if you have the option you may as well do what you can now while the dirty work is going on for peace of mind. Whatever your builder says there will defnitely be a little condensation whatever the set up, unless you have a really powerful fan or the extra fan on the chimney - its just physics and gravity that can’t be avoided. Either way you want to get it sorted now in my view rather than later as you probably won’t get round to it, as has been the case with us. That said, like I say it’s not a major issue if you have the same results as us. Only thing a few people have said is that over time it will cause the fan to fail but I haven’t noticed any problems yet so all good so far touch wood

Hi Maria, I have replied to your message aswell. This diagram may assist .. the blue pipes are the under floor heating. ..however this is not gospel as they are a few ways to do this.. your builder / architect should be able to advise further. Also we (BORA) dont do a BORA simple.. i think you are after a BORA Pure.
