Flat Roofs: Pros and Cons

Whether designing a new house or considering a roof replacement, flat roofs come with many unique characteristics that make them a popular choice for many homeowners and builders. Below, we’ve outlined the pros and cons of flat roofs.

The Pros of Flat Roofs in Arizona


Flat roofs tend to have a lower installation cost compared to pitched ones. They require fewer materials and are easier to install, making them more cost-effective.

Energy Efficient

Flat roofs from TPO or EPDM are energy efficient, long-lasting, and lightweight. In addition, they help reduce heat absorption in hot months, so you can rely less on air conditioning, reducing your carbon footprint and monthly expenses.

Space Saving Design

Flat roofs provide more efficient use of square footage because most don’t require additional attic or loft space. This extra space can be used for storage, insulation, or outdoor living space.

The Cons of Flat Roofs in Arizona

Inadequate Drainage

Flat roofs require careful upkeep to avoid water, snow, and debris buildup, which can lead to leaks and damage. Routine inspections and maintenance are essential for a longer roof lifespan.

Not Suited For All Climates

A flat roof may not be suitable for areas with heavy snowfall. The weight of accumulated snow can lead to structural issues or collapse. Carefully consider your location and weather before opting for a flat roof.

Aesthetic Appeal

When considering a flat roof for your home, consider how it may affect its aesthetic appeal and resale value. Flat roofs are more modern and minimalist than pitched roofs, which could reduce your home’s saleability.

Pitched Roofs: Pros and Cons

Pitched roofs are a classic choice for many homes and remain one of the most popular roofing choices for residential homes. However, there are some pros and cons you should consider for this type of roof:

The Pros of Pitched Roofs in Arizona

Aesthetics and Versatility

Pitched roofs are popular for their aesthetic appeal, with various styles, materials, and colors available. It can add a touch of elegance to the exterior of your home. Furthermore, its sloping design offers extra space beneath the roof, which can be used for an attic or vaulted ceilings for additional storage or living space.

Durability and Longevity

Pitched roofs are advantageous for their durability and long lifespan. They rapidly drain water and debris, preventing damage and saving homeowners money in the long run. Some materials like metal or slate can last up to 50 years with good maintenance.


Pitched roofs can provide improved insulation, creating a protective barrier against extreme temperatures and helping to keep energy costs down. They also offer additional attic space for extra insulation.

The Cons of Pitched Roofs

Initial Cost

One of the most significant disadvantages of pitched roofs is their initial cost and installation complexity. Depending on the materials chosen, a pitched roof can be more expensive than a flat roof.

More Challenging to Maintain

Pitched roofs require more challenging maintenance compared to flat roofs. Sloped surfaces can be difficult to access and may need professional help for roof repairs or replacement.

Limited Roof Space

While pitched roofs can offer additional interior space, they provide less flexibility for exterior roof usage. Homeowners looking to install solar panels, rooftop gardens, or other roof additions may find it more challenging to do so on a pitched roof than on a flat roof.

Which Type of Roof is Best For Your Arizona Home?

In the sunny state of Arizona, homeowners can choose between flat and pitched roofs. While flat roofs boast resilience to harsh weather and contribute to reduced energy expenses, they tend to have a shorter lifespan and demand extra care.

On the other hand, pitched roofs offer superior elemental protection, efficient water drainage during heavy downpours, and enjoy a longer life thanks to minimal debris build-up and water pooling.

Depending on where you live, both options could be suitable for your home. By considering all of the pros and cons of a flat and pitched roof, you can decide which type suits your Arizona home.
