Why, seriously, do we put up with ineptitude at this scale? These things perish within 5 years MAX and literally no-one seems to replace them proactively as required. They fail without warning and leak into everything below, in literally the rainiest, wettest, clungiest, dampest country with the biggest mould problem on the globe as a direct result of insufficient weatherproofing. It's MADNESS how they still contruct flat roofs over something pitched. It's just laziness. I've had to gut out so many of these fuckers and corrugate over new carcassing timber because everything underneath was sodden and fucked

clown country. not a serious country

Frankly I've never understood how flat roofs can work at all. Even a slight angle would help immensely with shedding water, since no surface is perfectly flat and you'll always end up with low spots holding water. And it doesn't matter what you use to waterproof it, getting beaten on by the elements and thermal contraction/expansion is going to break it eventually.

>Frankly I've never understood how flat roofs can work at all.

Most flat roofs aren't completely flat. They have a few degrees of slope for exactly the reason you pointed out. It's close enough to call "flat", and comes with all same sealing/waterproofing problems that implies. It's sometimes nice for commercial purposes, where you can hide utilities (HVAC, especially) on the roof. If you don't have some specific reason to do it, though...it's kind of just worse than a normal, sloped roof.

You're too right. It doesn't work. It is sheer laziness. Literally tens of millions of homes, sheds and garages up and down this wet-as-fuck country has them. Felting is a meme. Felting to replace perished felt is genuinely the biggest cop-out. It's just kicking the can down the road. It's fucking lazy, and costs more money in the long run than just ripping, pitching with timber, reinforcing, sealing and corrugating. IDFGI. These scufties that built all these homes and buildings must have been dreaming of Spain or something

>Felted flat roof
just felt or with Hot Mop and gravel?

when I was clearing Home Inspections on SF Gay Area, I'd see shit like "recommend cracks showing on exposed Hot Mop be filled and additional gravel covering" on hot mops that were well over 30yrs old, and still likely good for another 20.

I'd just pour some of WTF "cold hot mop" shit out of a jug and dump some more gravel.

>>2935394
Just felt, none of that gay shit. UK buildings probably have the same shitty solutions available to it, but the lifetime for these is definitely not 20yrs with our rain and cold

>>2935317 (OP)
Bongland is a clusterfuck of weird and inconvenient engineering.

They use separate hot/cold water taps. They have never heard of detachable door hinges.
Worst of all they have house doors that lock without using the key. You just lift the handle and it locks the door. If you lock your front door the keys are still inside, you're fucked.

>>2935423
Having lived in Ireland (read:UK in effect) it's the same. You have to replace everything. Mixer taps. Replace all hinges. Fucking SPRAY insulation, son, SPRAY insulation. Lazy as FUCK. That being said, there's so much to do that you end up driving tonnes of value into your property (60-80pc of UK wealth is in property) by just fixing shitty engineering. Even the 'not a fixer-upper' benefits to the point that basic stuff adds like 20-25pc the home value, like loft, building shelves under the stairs, reskimming/sanding ceilings and walls

All of the self-locking doors I've seen don't even require you to lift the handle. You just close the door, and it's locked.
The bolt has a sloped edge and retracts back on a spring as you close it.
The do seem to be on the way out though. The lock assemblies usually look pretty old and I don't find them in newer builds.

>>2935317 (OP)
they are pitched, just very slightly
the reason is cost. flat roof goes on a garage; you aren't 'supposed' to put anything in there apart from your car (i.e. nothing that will get ruined by flat roof collapse) but of course people pick the cheap option and ignore the intended application.
anyway, flat roofs work perfectly well all the time and can last decades quite easily.

>pitching with timber
depends on planning permission
>>2935394
flat roofs now are edpm or similar, single sheet of rubber glued down with some 2 part. of course you will want a conversion and building control will tell you to do a warm roof and you will condense a load of moisture in your celotex and the roof will rot in 6 months precisely because the waterproof layer was waterproof.
>>2935423
no door lock exists where lifting the handle locks the door. a night latch locks itself when the door closes. a deadbolt will lock with the key. a euro style cylinder throws the latch with the handle but that action alone isn't irreversible.
>>2935424
can't believe people really take the time fucking around with mixer taps setting the temperature faffing around. just use freezing water to get a lather and then burn your skin off on the rinse when the boiler kicks in. if it bothers you that much get a thermostatic mixer at the basin so the hot is comfortable. mixers are fucking retarded and lame.
spray insulation lol ok yeah if a guy comes round your house offering to tar your drive and his wife tries to sell you heather maybe dont let him insulate your house too.
>>2935497
they are on the way out only really because of the rise in popularity of upvc doors which don't easily accept them. they are still quite popular for e.g. apartments where you don't need the full security of a deadbolt but still don't want people wandering in, and also the doors are wood because they are 'internal'

>>2935497
Can vouch for them still being on builds from 1970s through 2000s in varying boroughs in UK
>>2935509
>because of the rise in popularity of upvc doors
what you on about son it is the rise of composite doors that's begun getting rid of these - uPVC doors almost universally had that mechanism

>>2935509

negro what?

disagreed, hence the thread. Any surveyancing worth a damn will make provision to outline the potential for failure at any time

fuck the UK

>>2935530
You have to get permission to change the kings things

>>2935423
>Worst of all they have house doors that lock without using the key
These fucked me over so many times. Even if you leave them open some air or a nice neighbour will close them.

>>2935563
i've been getting fucked by the king's thing longer than you've been able to use an angle grinder

>>2935509
>The roof will rot in 6 months
And a flat roof won't? Doing a proper apexed roof, not like a nigger, will last orders of magnitude longer than a felted/EDPM flat roof.

For years, people did what was popular. That’s all it took. Take conservatories, for example. I don’t think there’s another country on the planet where these are still popular other than the UK and Ireland. Flat roofs were the same, the building trade popularised them in the 50s-70s for public buildings and commercial properties and it went from there. For years it was a case of every extension, every annex and every kitchen rework having a flat roof involved in some way

We are now into rendering and resin drives. Every single person I know with one of these, or both, has some drama down the line. It’s just fashion and if you avoid it you’ll do alright

>>2935509
>mixers are fucking retarded and lame
Do you guys shit outside as well just like those "new british" fellows?

>>2936027
Another fantastic example of where popular ≠ good. Moreso that popular = convenient for the people who know how to do it or can (barely) be fucked to do it. I just don't understand how anyone thought flat roofs were a bright idea in the most dismally rainy country

>>2935317 (OP)
Sounds like it should be coated shortly after install, and once that coating starts wearing after several years should be re-coated. In this way the felt is preserved.

>>2936544
This is never done. Brits and owners of flat roofs do not do this. On those tins, it says that this is a meme that won't actually fix lazy negligence which will cause more substantial leaking issues, or shite planning by not pitching the roof in any meanginful capacity and corrugating over it

>>2935326
>>2935317 (OP)
Because its SOVL

>>2935348
My store has a decently angled roof. They still mounted all the compressors and shit up there. They use these things called "stands" to keep them level. I wonder if this is a new technology that hasn't spread beyond my 60 year old store.
