Flat roofs may evoke images of commercial structures like shopping malls or hospitals. Yet, they're popular in residential designs too. Homeowners seeking unique architectural styles. Or if you need rooftop space for decks or mechanical equipment.

Jacksonville homes can feature several types of flat roofs, including:

  • Built-up roofing (BUR)
  • Modified bitumen roofing (Mod-bit)
  • Single-ply membrane roofing (TPO, PVC, EPDM)
  • Spray polyurethane foam (SPF) roofs
  • Green or vegetative roofs
  • Metal roofs
  • Liquid Applied Roofing
  • Coating Systems

The best choice depends on local climate conditions, architectural design, and budgetary constraints.

Which Flat Roof Works Best in Coastal Regions like Jacksonville?

Jacksonville's coastal environment necessitates a robust flat roofing system. One that can withstand high winds, heavy rains, UV exposure, and the corrosive effects of saltwater.

A few worthy contenders include:

  • TPO Membrane: These flexible roofing systems resist UV damage. Which makes them a good choice for areas with strong sunlight.
  • Modified Bitumen (Mod-bit): Known for its long-lasting durability and resistance to water and wind damage. These roofs are popular choices for Jacksonville's coastal homes.
  • Metal Roofs: With exceptional durability and resistance to corrosion caused by salt air. Metal roofs offer a long-term solution for coastal living. 
  • Built-Up Roof (BUR): Consisting of alternating layers of asphalt and reinforcement. These roofs provide a formidable barrier against water and wind damage.

Consult a local flat roofing contractor who understands Jacksonville's specific weather patterns. By doing so, you'll get the best roofing solution for your home.

Mod-Bit Roofing is a Viable Option for Jacksonville Homes

Modified bitumen (mod-bit) roofs are common for commercial and industrial buildings. But they're also suitable for residential homes in Jacksonville. Widely used on Jacksonville homes too.

The key benefits of mod-bit roofs include:

  • Durability: Composed of a blend of asphalt and rubber-like materials. Mod-bit roofs offer excellent resistance to water and wind damage.
  • Longevity: Mod-bit roofs generally outlast traditional asphalt shingles.
  • Ease of Installation: Mod-bit roofs are easy for an experienced roofer to install. Which makes them a cost-effective choice for homeowners.

Mod-bit roofs also offer a wider range of colors to match your home's exterior. Sometimes a flat roof is not necessarily flat. So, having the ability to select a color can help your home's curb appeal.

What's the Cost of a Mod-Bit Roof for a Jacksonville Home?

 

Several factors influence the cost of a mod-bit roof. The main factors include the roof size, materials used, complexity of installation, and your home's location. As a rough estimate, a mod-bit roof may cost between $5 to $9 per square foot installed. For an accurate quote, we recommend you get two to three local flat roofing estimates.

 

Is TPO Roofing Suitable for Jacksonville Homes?

TPO (Thermoplastic Olefin) roofing is one of the most popular flat roofing materials. Many Jacksonville homeowners have TPO roof systems on their homes.

Here are the reasons:

  • Durability: TPO roofing resists UV, ozone, and chemical damage. Which makes it suitable for Jacksonville's sun-drenched environment.
  • Energy Efficiency: By reflecting the sun's rays, TPO roofing can reduce cooling costs.
  • Waterproofing: TPO roofs are heat-welded at the seams to create a robust, waterproof seal.
  • Flexibility: TPO roofs are easy to work with. This allows a roofer to shape and mold the membrane. Making it easy to stop water intrusion in hard places. This helps reduce the installation costs.

How Much Does a TPO Roof Cost for a Jacksonville Home?

 

The cost of a TPO roof can range from $6 to $12 per square foot installed. It varies depending on your roof's size, the materials used, the complexity of the installation, and your home's location. Remember, these are ballpark figures, and actual costs may vary. TPO may be more expensive than traditional roofing materials but it last longer too.

Decoding Flat Roof Options: TPO vs. Mod-bit for Your Florida Home

 

In the world of flat roofing, there is a plethora of material options at your disposal. Yet, when it comes to residential applications in Florida. Especially considering the coastal weather.
