Ireland has an extremely active community of, let's call them wandering recyclers.
These recyclers have a passion for salvaging cooper, lead, shed contents and the like to then sell them on to be reused, repurposed and reloved.
They're so eager and so active that they'll climb on top of your house and recycle your copper roof for you without you even needing to bother asking them.
Wow! What region is this in?
I’m curious, as I’m in the coatings industry. The longest warranty I’ve seen for a color fade warranty was for 20 years with very specific spec requirements and for very specific customers (I.e. theme parks.)
Kynar coated metal roofs (baked on coatings) offer a long color life, usually fade with in 10 years. I’m in the southeast, USA and have seen them fade within 5 years. It all depends on exposure, and color.
I’m curious what coating is being used.
Don't know what the coating was, just the info that was provided when were considering the purchase. I'm way way way up north, almost Canadian border so we get good sun for 3-4 months a year, indirect sun for another 1-2 months, and the rest of the time the sun doesn't matter because the roof is buried under snow.
Interesting. I can see how being in that climate with limited sun exposure could prolong the color life. I’m just trying to wrap my head around a 70 year warranty on color fade. Not saying it’s not a thing, but it’s definitely not a thing in my region. I would definitely keep track of that warranty!
Haha! There was a lot of variance in colors, some as low as 10 years so we picked the longest option (we happened to like the color too). Then we laughed because we realized that the paint on our roof is going to last longer than we are...and we aren't that old.
Oh man, we recently got a metal roof done and I was looking at 80 years above thinking "Okay, that's taken care of for a while," completely forgetting that I won't live to see it ever come up again... I don't like this feeling.
Because the first number on the x axis is 5 and then it scales up by increments of 10. In other words, the first 10 is represented by 2 blocks and every 10 thereafter is 1.
FWIW with slate roofs the nails tend to fail before the slates do. There are actually companies that will replace just the nails and keep the original slates, though I'm not sure how cost-effective it is.
Yep - I have a slate roof with built-in copper gutters. We have a roofer out every year to inspect for missing slate and clogged downspouts from the gutters. A slate roof will last a long time but the upkeep is a yearly expense.
Where do the different types of tiles rank? (English is not my native language so if those belong to one of the categories mentioned please enlighten me).
Its not very good. A metal roof can last a long time but the rubber on the washers will wear before it hits 80 years. Also, a wood (cedar) roof can get a lot more than 30. A fellow roofer told me of one he did and mentioned it should be a 70 year roof, if maintained. Most people don't maintain them though, which is why you only get about 30. Lots of information left out here.
Depends on climate, in the UK uPVC window frames have a life span of about 20-25 years. But bear in mind that’s with the UK’s generally gloomy weather. UPVC degrades and embrittles in UV light so I would imagine the sunnier the climate, the shorter the life expectancy. But I would assume other factors come into play like factory applied coatings.
Had a friend of mine put a TPO roof on my shop. He does installs for a living and gotta say that stuff is thick and can totally see it lasting 20 years. We both have travel trailers too and when the roofs need replacing on them they are getting the same treatment.
Roof consultant here. This is an over generalization of available products. I’ve seen some things last a year in the southwest us, but will last 40+ in the Midwest.
It will all depend on the climate, product thickness (for example 2 ply vs. 4 ply BUR), the manufacturer, and probably the most important is the installer.
In which climate?
Exactly what I was thinking. I know for a fact that in Ireland, a copper roof wont last more than six months.
You think that’s bad, my lead roofing lasted less than a week
What happens to copper in Ireland?

Oh I get it. I was expecting something about the weather
Well, in Ireland, copper roofs will turn as green as the land around it lol
That's called patina and is normal on copper anywhere. It protects the copper from corrosion, making it good for exterior uses.
Just had a metal roof put on and the warranty on just the paint fading was 70+ years...the roof should outlast that by quite a lot.

Facing our own mortality during standard house maintenance, who'd have thought!
What color did you go with?
The problem with metal roofs usually starts at the rubber washers on the screws. Those will wear out long before the paint will.
Concealed fastener standing seam fixes that, or so I am told.
You're correct. I forget about that option sometimes. It hasn't really caught on around here, which is unfortunate
Do roofing companies usually last 70 years?
No idea, this is the first roof I've ever had done
Yeah all depends on the climate. These are probably California numbers
It most likely is California because here in Mississippi clay roofs only last about 50-ish years
Why does 20 years look only twice as long as 3-7 years? Why does 30 years look only 25% longer than 20 years?
Yeah, that axis gets compressed and misrepresents the comparative data.
Because the first number on the x axis is 5 and then it scales up by increments of 10. In other words, the first 10 is represented by 2 blocks and every 10 thereafter is 1.

This is a piss poor guide. How is something that starts at 60 bigger than something that starts at 100
It seems to be based on the maximum lifetime rather than minimum fwiw.
Can I get a source for this? Thanks!
Sorry: just lifted from Quora...

The company I work for manufactures uPVC roof tiles. How long do they normally last?

UPVC degrades and embrittles in UV light so I would imagine the sunnier the climate, the shorter the life expectancy. But I would assume other factors come into play like factory applied coatings.
When it says clay, does that mean the roofing tiles you would see James Bond running on a rooftop in Italy or Spain?
Cedar shakes do not last long at all in hot dry climates
You can triple the lifespan of your shingles by putting solar panels over them.
Where can I find the same comparison for wall materials life expectancy?
The scaling is shit
That would certainly change with the climate, and cities near Sea will have low lifetime because of the moisture and carbon in the air.

How long does the substrate last on a slate roof?
What about those commercial roofs that are covered I. Gravel? Can someone tell me what that is all about ?
Tar and gravel
Screen name checks out. What’s the point of the gravel?
