Flat roofs reduce construction costs, create additional outdoor space, and withstand direct heat, but they also require proper drainage, especially after a storm. Based on the landscape and the ever-changing Utah climate, many homeowners opt for a flat roof to strike a balance between durability and versatility.
Join M&M Gutters and Exteriors as we examine the pros and cons of flat roofs to understand what makes them so popular.
What Is a Flat Roof?
A flat roof is a horizontal surface with a low-pitch roofing style that maximizes the usable space of your home. It’s a modern roofing design and is easy to install.
Types of Flat Roofs
Why use a flat roof? Before we answer that, understanding that not all flat roofs are created equal will help you know if this is the best roof for your home. Here are some of the most common types of flat roofs to consider for your Utah home.
BUR (Built-Up-Roof):
BURs are a classic choice commonly seen in commercial buildings. It is constructed with layers of asphalt reinforced with ply sheets for durability and weather resistance
EDPM
Ethylene Propylene Diene Monomer, or EPDM, is a synthetic rubber membrane often chosen for residential properties for its versatility and cost-effectiveness.
PVC
Polyvinyl Chloride, or PVC, is very durable and resistant to chemicals and harsh weather. This single-ply membrane is popular in both residential and commercial properties.
TPO
Thermoplastic Olefin, or TPO, is commonly used for commercial roofing due to its energy-efficient property to reduce cooling costs.
Spray-On Coating
This innovation involves spraying a layer of foam or coating directly on the roof. It is versatile, making it applicable to various structures.
Modified Bitumen
This type combines asphalt with modifiers for added flexibility and strength. Its high resistance and durability make it ideal for properties in high-traffic areas.
These flexible flat roof options have their unique flat roof advantages. It is important to know what they offer and the pros and cons of flat roofs to make an informed decision for your home.
Pros of Flat Roofs
More homes are embracing the clean lines and modern appeal of flat roofs, but there are more practical benefits of flat roofs than just aesthetics. Knowing these benefits of flat roofs will help you understand what makes them popular.
Energy Efficiency
Energy efficiency is one of the main advantages of flat roofs, particularly in maintaining the temperature inside your home, thanks to their small surface area and materials, allowing for less heat loss.
Affordability
The simplicity of a flat roof reduces the need for materials, making it a cost-effective roofing alternative to pitched roofs.
Easy to Clean
Another reason to choose a flat roof is that they are easy to maintain. Their flat surface makes cleaning and inspection easier.
Cheaper Repair Costs
The ease of access on flat roofs also results in cheaper repair costs. Also, their minimal space means fewer materials are needed for repairs and maintenance.
Usable Space
Flat roofs also provide a flexible space for any home. You can transform this flat surface into a rooftop garden, lounge, fire pit, or even a project area.
Easier Installation of Solar Panels and Equipment
Another benefit of a flat roof is its level surface, which provides a hassle-free installation of equipment such as solar panels and HVAC.
Flat roofs have more to offer than just a modern look. They provide practical efficiency and functionality that will help you maintain your home.
Modern Design
Flat roofs create a modern, sleek appearance that enhances the curb appeal and resale value of your home.
Cons of Flat Roofs
Like any roofing solution, there are also disadvantages of flat roofs. To help you make the best decision, we will also let you know what are the disadvantages of a flat roof.
Blistering and Crackings
Over time, your roof’s prolonged exposure to the sun and weather can lead to blistering and cracking. This can weaken durability and compromise its integrity.
Impact Damage
The level surface of flat roofs, while providing convenience and practicality, is prone to direct impact from hail or falling debris. While the likelihood of these can vary, it is still a factor to remember when making your choice.
Less Insulation
Flat roofs have less insulation compared to pitched roofs due to limited space and the absence of an attic.
Disintegrating Panels
Some roofing materials can disintegrate or deteriorate over time. Familiarity with your materials will help you understand and determine their limitations.
Unreliable in Cold Weather
Flat roofs may not be the best option for areas with harsh winter conditions, such as Logan or Park City, as snow accumulates on their surface, potentially resulting in leaks or structural issues.
Potential for Leaks
Flat roofs have a higher risk of leaks since water doesn’t run off your roof naturally like it does with a sloped roof. Over time, even small amounts of water can lead to costly repairs if not addressed properly.
Drainage Issues
The level surface of a flat roof can also cause water to accumulate, causing poor drainage. Getting an experienced flat roof installer to design and maintain your roof is important to avoid this issue.
Maintenance Issues and Early Replacement
Like any roofing, flat roofs require regular maintenance, which is the key to their longevity.
Weight Concerns
Any heavy roofing features, such as a rooftop garden or equipment, can affect the structural integrity of your flat roof.
Short Lifespan
Flat roofs typically only last up to 30 years, whereas pitched roofs can last up to 50 years.
Traditional Roofs Are More Stylish
Some homeowners find sloped roofs more architecturally stylish. Flat roofs are functional but do not provide that same visual appeal.
While there are practical benefits of flat roofs, it is also important to know the pros and cons of flat roofs to make the best decision for your home. Are flat roofs better? Or do the disadvantages of flat roofs outweigh the benefits?
What Is the Life Expectancy of a Flat Roof?
The lifespan of a flat roof can range from 15 to 30 years, depending on the quality of materials, the climate in your area, and the level of care you provide for your roof.
Are Flat Roofs Hard to Insure?
Flat roofs are more difficult but not impossible to insure. Many insurance companies view flat roofs as a higher risk due to water leaks and damage; however, maintaining proper drainage can help lower your insurance costs.
What Are the Disadvantages of a Flat Roof?
Flat roofs have less natural insulation than pitched roofs and require more maintenance to remove snow, debris, and water to keep your home protected.
Are Flat Roofs Worth It?
Yes, flat roofs are generally worth the investment. With a flat roof, you can save money, add more outdoor space, and enhance the aesthetic appeal of your home.
Is a Flat Roof a Good Choice for Utah Homes?
For those in Utah, where the sun paints the skies with vibrant hues and the weather swings between seasons, a flat roof has been a popular choice among homeowners. The advantages of flat roofs align perfectly with the conditions of Utah living, particularly in high-snow areas such as Park City and Logan, as well as in warmer regions like Moab and St. George.
Aside from the functional benefits of flat roofs, the leveled surface provides several options that every Utah homeowner will enjoy as it complements Utah’s love for the outdoors. The roof becomes more than just a shelter. It serves as an extension of the living space; whether it becomes a rooftop garden or a relaxation area, it will allow you to embrace the surroundings that Utah has to offer. Aside from this, the surface also allows for easy installation and maintenance of solar panels, perfect for the abundant sunshine in Utah.
If you are looking for a roofing solution that provides you with functionality, practicality, longevity, and, most of all, the enjoyment of and appreciation for your Utah neighborhood, then a flat roof is the best option for you.
