The answer to 'flat roof vs' is that flat roofs and sloped roofs each have their own advantages and disadvantages. Flat roofs are generally more cost-effective to install, but they require more maintenance to prevent leaks and pooling water. Sloped roofs are more visually appealing and better at shedding water, but they are typically more expensive to install.
The best choice between a flat roof and a sloped roof will depend on your specific needs, budget, and the climate in your local area. Consulting with a professional roofing contractor can help you determine the most suitable option for your home.
