The answer to 'which is better flat roof or pitched roof' is that both flat and pitched roofs have their own advantages and the 'better' option depends on the specific needs and constraints of the homeowner. Flat roofs are generally less expensive to install and maintain, and can provide more usable rooftop space. However, they are more prone to leaks and ponding water, and may require more frequent repairs. Pitched roofs, on the other hand, are better at shedding water and snow, and can provide more attic space, but they are typically more expensive to install and maintain.
When deciding between a flat or pitched roof, homeowners should consider factors such as climate, budget, desired aesthetic, and the intended use of the rooftop space. In some cases, a hybrid approach with a low-slope or 'flat' roof that has a slight pitch may be a good compromise. Ultimately, it's best to consult with a professional roofing contractor who can evaluate your specific needs and recommend the best solution.
