I would like to build a bungalow on my property.
I am pondering on the shape of the roof.
A single pitched roof is nothing like a flat roof, but with a slightly sloped roof to allow water to drain better.
In the past, there were almost always problems with flat roofs and their leaks after a few years. How does today's single-pitch roof design differ from a hip roof? Is a hip roof always safer than a single-pitch roof in terms of leaks after 20 or 30 years? Or have mono-pitch roofs become so watertight that they no longer have any disadvantages compared to hipped roofs?
A single pitch roof is different from a flat roof. The addition has a higher ridge on the outside, allowing light to enter through the windows on the first or second floor. A sloping roof allows for a slope greater than 4 or 8 degrees (<- flat roof).
Due to the described windows, the monoshield house looks more modern than a conventional hip roof.
The design of a single-pitch roof is different from a hip roof.
So what do you want? A single pitched roof or a flat roof?
The roof has to match the house, there is no particular type of roof for the style of country home.
With a lean-to roof, the orientation is more important for any PV you might want (depending on the actual angle of the roof).
Theoretically, you could use all sides of a hipped roof with a flat roof pitch up to 25°.
The ugliest of all roofs.... Always looks like bad asymmetrical 80's inspired postmodern architecture.
In my opinion, the risk of leaks (all other things being equal) is related to the pitch of the roof.
So, whether it's a single pitch or a hip roof, 25° is better (against leaks) than 15°.
In the end, it doesn't matter whether the roof is flat, single-pitch, hip or gable. All modern roofs remain watertight for a very, very long time if done judiciously.
Whether it's a single-pitch or hipped roof, the limit for additional waterproofing is a 22° pitch for most types of shingles. Below this level, additional waterproofing is required. In this case, the slope of a tile roof can be at least 7 °. Below that is a special sealed flat roof.
According to an architect in my family (but also retired), flat roofs are ALWAYS problematic, and she would NEVER build a flat roof.
From my office, I can see our neighbor's roof (a flat roof bungalow built around 1980) where there is always water on the roof. Even if it has been dry for 2 days. Last summer he covered the roof with new asphalt sheets.
