The answer to 'difference between flat roof' is that flat roofs and pitched roofs have distinct features, benefits, and use cases. Flat roofs are horizontal or nearly horizontal, with a slight slope to allow for water drainage. They are commonly used on commercial buildings, multi-unit residential structures, and some modern homes. Pitched roofs, on the other hand, have a steeper slope and are more common on single-family homes. They are better suited for shedding water and snow, and can provide additional living or storage space in the attic.
In terms of costs, flat roofs are generally less expensive to install than pitched roofs, as they require fewer materials and labor. However, they may have higher maintenance costs over time, as they are more susceptible to pooling water and leaks. Pitched roofs, while more expensive upfront, can have a longer lifespan and require less maintenance in the long run.
