Despite the name, flat roofs aren’t completely flat. They actually have a bit of a slope (about 1/8 inch per foot) to allow rainwater and ice melt to drain. Flat roofs are usually made from a two-ply watertight membrane covering that stretches over the entire roof.

This type of roof is common in commercial buildings, but are also used in modern minimalist and Southwest-style homes. Flat roofs provide space for solar panels, an outdoor recreation area, a rooftop garden, or even a pool.

Here are some other benefits of a flat roof:

• Easier access for homeowners and professional roofers
• Leaks are easier to find and patch than those on a sloped roof
• Made of durable materials that are resistant to punctures and rips
• Less expensive than pitched roofs
• Provides easy-to-access space for cooling and heating systems
• Helps reduce heating costs during winter

Though flat roofs are good-looking and are well-suited to certain architectural designs, they are generally susceptible to the effects of sunlight, wind, water, and temperature changes. During inclement weather, water can collect on the surface of the roof and cause leaks and extensive water damage. This is why regular inspection and maintenance are necessary if your home has a flat roof.
