Flat vs. Pitched Residential Roof

Technically speaking, flat roofs are not completely flat. For rainwater to drain away, they typically have a pitch of a least a few degrees. In fact, any roof with a pitch of 10% or less is considered “flat.” Here’s a short rundown of the pros and cons to each roof system.

Pitched Roofs

• Pros: Preferred by most homeowners, a pitched roof gives a traditional feel to a home. It also drains water more efficiently. But, even though the water runs more easily off a pitched roof, you still need to make sure your roof system is designed to properly direct it away from the house.

• Cons: More difficult to clean and inspect, pitched roofs also come with a heftier price tag. If you plan to replace a flat roof with a pitched one, keep in mind that the new roof will place a greater burden on your home’s structure and foundation. 

Flat Roofs

• Pros: Easier to install, less expensive, and lower maintenance, flat roofs are also best for certain architectural styles. For example, historic modern design often features a flat roof to complement the natural landscape. Another advantage that's often overlooked? You can use the space to install heating and cooling units, turn it into a deck, or more easily install solar panels, a nice eco-friendly roofing option.

• Cons: Besides the obvious drainage disadvantage, leaky flat roofs can quickly damage ceiling, walls, and other wood structural elements. To mitigate this risk, a rubber membrane can be added.

The Verdict

When making up your mind, consider the materials to be used, the architectural style of your home, cost, routine roof maintenance, durability, and weather conditions. All these elements taken together will help you make an informed choice. If you still have questions, a professional Las Vegas roofing contractor like First Quality Roofing & Insulation can help.
