I don't care much for shingles myself. I'd rather go with tin, the ultimate shed roof!

Are you talking about the "shed" roof style, or are you talking about roofs on sheds? Also, "what's up with X" is a pretty vague question, not sure what kind of reply or information you're looking for. Please clarify your question.

My roof is made of ceramic tiles, like God intended

Pretty mind boggling that the only thing between weather and the house is a miniscule layer of tar

The roofing structure around here is so complex this indeed looks like a shed in comparison, multiple layers of construction, made to hold up hundreds of years

>weather and the house is a miniscule layer of tar
I mean technically it's a couple layers of shingles at the very least and some ice and water dam under that, but ok, you can pretend whatever you want.

why are you replying to OP? you don't even know what he is asking or even wanting.

>>2979830
he is talking about american obsession with papering the roofs of their cardboard and glue houses with gritted felt.
he is of course incorrect, the rest of the civilised world does not use the same kind of tar paper felt for their roofs and dog houses as americans use for their houses, in stead of small sheets of tiles they prefer long rolls which means fewer joins and less chance of failure. also they are often 'glued' with either hot mop bitumenn or cold glued where the tar is mixed with solvent that flashes off as it goes off. so euro shed roofs are less prone to wind damage.

>>2979889
I've never seen anyone roof their house like in OP's picture.

I've had a roof that was asphalt shingle, and they put down a rolled out layer of tar paper or some other underlayment, and then the shingles.

and I have had a tiled roof replaced, and it is the same thing an underlayment, and then the tiles.

>>2979889
It's substantially cheaper to use asphalt shingles

>>2979891
costs half the price and lasts less than one fifth of the lifespan. your right its a no brainer.

Bro, are you really this ignorant of how shit works? Let's walk you through it like a fucking child. I'll even use crayons. Picture related.

Most houses are not built by the people that live in them. They are built by developers. No on can afford to pay to live in a place while also pay to have a place built.

Who pays for the roof when the house is built, the buyer or the developer? The fucking developer. They want to build it as quickly and cheaply as possible to maximize profits. They don't care about longevity because they ain't moving in. They only care about the profit because that is how companies work. Homes here are so fucking expensive that using higher quality materials only raises the costs, not the profits.

Other systems also take longer to install and require actual skill. That slows down construction on the neighborhood and means the company can't hire a bunch of fucking literate, illegal, alcoholics to knock the shit together. Everything is designed to go together fast using materials delivered that day to maximize profits. It is fucking stupid but this is the third world that we live in here in the States. Thank 50 years of shitty politicians running this country.

In my area metal roofs are cheaper and they take less time to install in most cases. The only time anyone uses shingles these days is if there are a bunch of angles and roof joints.

>>2979912
This is all true. And then when the 15-20 year lifespan of the cheap shingle roof is over the people living there can decide whether they want to upgrade their roof to something else or go back with shingles again... It's almost as if it makes the homes cheaper to purchase up front and then allows the new owners to weigh the options of upgrading when that time comes... Imagine that!

>>2979915
So basically all muricans buy houses with temporary roofs and are ok with it?

>>2979950
>So basically all muricans buy houses with temporary roofs and are ok with it?
Not all houses, but If they're mass produced cookie cutter housing then yeah they are more than likely getting the fastest cheapest option. Cuts the up-front cost of the house and gets them in a house a bit faster. Gives them time to save up and upgrade the roof when it needs it, or not. Their choice.

>>2979950
It costs 5k for a shingle roof and it'll last 20 years
Better than anything else

at which point my cheapass boomer dad started just buying a new tarp every year. repeat for 20 more years because why spend anything on maintenance of the once nice house you bought for $100k that now would sell for $1.5M?

minimum 30 years, and my old house the roof lasted 40 years.

>>2979950
all roofs are temporary.

>>2980396
If your die before your roof has to be changed, it's not temporary

>>2980396
>minimum 30 years, and my old house the roof lasted 40 years.
Really depends on the shingle quality and amount of wind and hail you get in your area too. Some quality shingles are definitely a 30 year roof.

Do metal roofs actually reflect IR pretty decently or is it a meme?

>>2979830
L shaped house. Gabled on the left and right of the _, but hipped on the top of the I, which is south-facing. Literally defeats the purpose of how gable vents function, by drawing cooler air from the non-sun facing gables and exhausting hot attic air from the one facing the sun. I also have ridgevents, but the soffit vents are only along the I part of the house so the right side of the _ got noticeably hotter than the rest of the house until I added a shit ton of extra insulation.

The hip is also where the fucking attic ladder is, so the slant significantly reduces attic storage space. Too expensive and annoying to fix because it's also where the electrical mast is attached.

Has anyone ever seen a butterfly style roof in the wild? Seems like a shit design...

>>2980512
I don't think it actually exists. Seems like a really stupid configuration as far as shedding water is concerned, while also being ugly as hell.

>>2980429
>Do metal roofs actually reflect IR pretty decently or is it a meme?
Depends what color the roof is. Having a metal roof painted black will absorb more IR than having a metal roof painted white. But that kind of works the same way with most roofs.

>>2980512
I seem to recall some airport using this design. I do remember seeing it on a house we did a teardown for years ago. Thing was straight out of the 60s, with a stone grotto and a completely fake grass lawn. I remember it because as we were surveying it my crewman said the only way it could get any better was if it had pink flamingos. Then we got to the back yard. Needless to say years of exposure to the elements does take the pink out of the plastic flamingo.

It's not too bad, in theory, by concentrating the rainwater into a channel you can control where that water exits off the roof and put a single big downspout or some other water feature below it, plus the more water that the channel carries the more likely that it will hit self-cleaning velocities like a sewer with only minimal pitch. The downside of course is that it needs extra waterproofing along the trough and that you'd probably still need to clean it periodically.

>>2980791
I've only ever seen them on carports out here... until a few years ago when an apartment complex in the area went up that used them. But wait, it goes worse. They aren't actually butterflys. They have a false butterfly facade that is only a few feet thick and then a normal flat roof. So, its only reason to exist is to make the building look ugly.

>>2979914
Where in America is metal cheaper than shingles? Even the most expensive asphalt shingles are more expensive than metal, unless it's some shitty 29ga exposed fastener ag panel.

I have a question about shed roofs (like the second one from the top & left in >>2979830).
how do I calculate the load this thing can sustain?
I live in an coastal area where it doesn't rain, it's humid but not hot (like, never. 25°C at most), and get no hurricanes, though there is the occasional . I want to put solar panels on top, and I'm wondering if a 9x5 garage would need additional support to the walls.
