Your Guide to Flat Roof Replacements

Whether for a residential or commercial structure, flat roof replacements are a critical part of protecting your property. This is especially true in Florida, where rainstorms and hurricanes can pose a serious threat to old, damaged flat roofs. But do you know about all of the flat roofing options in Florida?

We’re here to make sure that you do. PITCH Roofing was founded by experts with more than 60 years of experience in the roofing industry. Based right here in Pinellas County, nobody knows Florida roofing like we do. Let us prove it to you as we walk you through everything you need to know about Florida flat roof replacements!

Flat Roof Replacement Materials

Flat Roof Replacement Materials

In some ways, all flat roof materials work in the same way. Whereas sloped roofing materials (like shingles or tiles) only have to minimally protect against water since it moves freely off of sloped roofs, flat roofs have to have superior water protection to compensate for slower drainage.

This is also why you have to be careful with who you choose to do your flat roof replacement. A properly installed flat roof isn’t completely flat; it just has a very low slope. If your installers don’t carefully ensure that your roof is angled to help move water off, your flat roof could develop issues with water pooling. This can lead to issues with leaks, weathering, and pests.

But while all flat roofs serve the same goal, they come in many different materials. To get you ready for your flat roof replacement, let’s talk about some of the different ways that Pitch can get you a high-quality flat roof.

Modified Bitumen

Modified bitumen, or mod bit, is one of the most popular flat roofing options in Florida. This asphalt-based roofing material combines water-resistant rubber and fiberglass reinforcement to effectively protect your structure against the Florida elements. Thanks to its wide range of applications, mod bit is a common choice for both homes and commercial properties.

Part of what makes it so versatile is its tensile strength. Unlike some other low-slope roofing materials, mod bit resists puncture damage from storm debris and foot traffic. This means you don’t have to worry about branches falling in a storm and creating weak points in your roof! Thanks to this quality protection, mod bit roofs average around 20 years of life.

Modified bitumen flat roofs are generally black. This can help cover dirt and staining over the years, which is great if you own a commercial property where parts of the roof are visible from the interior of the building. On the other hand, this darker coloration also attracts more heat, so it can make your AC system work a bit harder in the summer months.

TPO

TPO, thermoplastic polyolefin, is a low-slope roofing membrane. In other words, it’s a single-ply roofing material that heat-adheres to your roof. This rubberized roof then creates a waterproof barrier to keep your roof decking dry and secure.

Invented in the 90s, TPO roofs are estimated to live for 20-30 years Since this is a relatively new roofing material, though, experts aren’t 100% sure exactly how long the average TPO roof lasts. It’s safe to expect a long life though, since its rubberized composition allows it to easily expand and contract with the sun’s heat, which prevents premature weathering.

Unlike mod bit, TPO is usually white. That means that your TPO roof will help reflect UV rays away from your structure and lower your energy bill. This can help offset flat roof installation costs and make TPO roofing more budget-friendly.

The Cost of a Flat Roof Replacement in Florida

The Cost of a Flat Roof Replacement in Florida

Now that you know the different types of flat roof replacements, let’s talk about how much they cost. For almost every roof replacement, price is a significant factor. But it’s important to balance a roof’s value alongside its installation costs.

With that in mind, let’s talk about how much each of these flat roofing materials could cost you in Florida!

  • Mod Bit: This is a very budget-friendly roofing material. At four to eight dollars per square foot, flat roofs don’t get more affordable than mod bit. On a 2,000-square-foot roof, that puts the modified bitumen cost range between $8,000 and $16,000.
  • TPO: This rubberized roofing material costs between four and 10 dollars per square foot, making it roughly equitable to modified bitumen. On that same 2,000-square-foot roof, your flat roof replacement costs would fall between $8,000 and $20,000.

Ranges like this are helpful guidelines, but you’ll need more information to plan a low-slope roof replacement. To find out exactly how much your new low-slope roof will cost, you need to start collecting roofing estimates.
