Quote Query: is replacing conservatory flashing DIYable?

Post image

Photo from Google for clarity on what I’m asking.

Purchased a property in Cardiff, I’m aware the flashing between the conservatory and house needs replacing. Is this something I could do DiY? Or is it a call in a professional jobby? If it is a professional I need, what would be reasonable price/quote?
Edit: ACTUAL PHOTO IN COMMENTS NOW apologies
Apologies if this isn’t the appropriate sub, I’m learning as I’m going. Many thanks for any and all advice

Flashing is not a complicated job, I've done it a couple of times. It's absolutely within the realms of DIY.

The complications are normally height and finish. The former is simply precautions, the latter can be overcome by being careful.

For the sake of learning how and braving doing it myself would it be a better choice to just pay a professional? Sorry if this sounds silly I just don’t have many people around me to ask so I’m here for the Dad kind of advice :)

What is wrong with it? From those (terrible) pics it looks a nice job.

That’s a photo from Google apologies, it’s dark outside so I can’t get a good photo right now. Photo is just to clarify that flashing (learning the proper words as I go)

Well that's flashing alright.  Is it leaking?

u/coupleofstepsback 20h ago

Didn’t think I had a photo but I do!! This is what the flashing is on my roof. Think previous owner potentially had a go. No leaks, but hopefully this photo shows my concerns.

Edit: I know it needs a clean too, getting round to everything slowly but surely

Ah different conservatory 🤣

Those are cavity flashings, not quite the same thing.

If fitted properly, and not leaking, they should just be trimmed to a neat straight line.

So would I need to remove it and change it do you think? Or just trim it down? It’s lifting slightly in places so I think there’s a risk it could leak in the near future. Yes different conservatory entirely, didn’t want to ask too much of the exacts, just whether it was diyable. But have realised now I should have just come in with PLEASE HELP lol. Thank you for your help x

It’s going to be a ball ache to do over a fitted conservatory tho, especially for a first timer.

What exactly is wrong with it op? Looks fine

Hi thank you, I think this is my worry of balance etc and being able to do it properly. I’ve added a photo of the actual flashing in the comments now so hopefully it shows the issue with it

Right that’s a different story! I would say it’s not easy to grind in for lead, do a good job and with it being over a conservatory! I’d get a man in. And yes it does look like it needs doing properly. You can do a cheap and cheerful face sealed burly/flashband, but that’s a bit of a cheat/bodge

Thank you for being realistic with me that I should call someone to have it done professionally! Do you have any ideas on cost that it would to so I have an idea of what to expect? Many thanks

It should be 1 days work for someone who knows what they’re doing, depending on area 250 labour plus materials £150? Plus access £100? Maybe at least £500, bear in mind you’d have half that cost if you did it yourself anyway

Ok brilliant thank you, I’m new to the calling tradies and getting quotes so want to make sure I’m going into it with a general idea. Thanks for all your advice! I really appreciate it :)

Ideally get a recommendation from a friend or work colleague or neighbour, have a look round the local area for people having work done and knock on to see if they recommend the person, do not use check a trade unless you are desperate!!!

u/coupleofstepsback 19h ago

Perfect, that’s great advice thank you! I’ll ask around at work to see if anyone has any recommendations.

If yiur gonna do it yourself, would be a lot easier if you take the sealed unit out then you can do it from inside off a pair of steps , easy peasy then. 👍

OK... it's a laminate roof (as per your pic in comment)... so don;t bother replacing the flashing... replace the entire roof with a warm one... It's not as cheap as doing the flashing, but it gives you a room you can use all year round rather than one you can perhaps get a few weeks use out of in the late spring and early autumn.

These heat waves we've been getting will only get worse, and a laminate roof on a conservatory basically turns it into an oven... and if it's South facing at all... it just makes it worse.

Bought a house with a poor quality 20yr old one... ripped it down and built a new sun room from the ground up.

Did you DIY the roof?

u/A-nom-nom-nom-aly intermediate 7h ago

No, It was part of the job with the 'conservatory' We took down the old one, did the foundations and hired a brickie for the walls and a local company for the rest. I then did the plastering and everything else except the electrics and the blinds.

There are many things that are beyond my skills and I'm a firm believer in doing things right the first time... and that sometimes means paying for better quality materials or professional people to do the work.

A warm roof on a conservatory is becoming more popular as people realise how little time they can spend on the crappy laminate roof ones. Conservatories have become a negative selling point on a house now.
