How a Modified Bitumen Roof Holds Up in Florida

How a Modified Bitumen Roof Holds Up in Florida

Modified bitumen is a special type of rubberized asphalt. This is what makes it such a good roofing material for Florida structures — the asphalt is durable and hardy, whereas the rubber improves water resistance and allows the roof to expand and contract with the sun’s heat. This flexibility goes a long way in protecting your roof and preventing premature aging.

In Florida, modified bitumen lasts about 20 years on average. Your roof’s lifespan could be as short as 15 years if you get unlucky, though. Over the course of your roof’s life, it’s common for it to need minor repairs every now and again. That’s why it’s important to keep up with proper flat roof maintenance, especially annual roof inspections.

Even following the best practices, though, there is a chance that your modified bitumen roof will need repairs. Florida’s weather is just too harsh on roofs to expect anything else. To help give you a better idea of how this happens and what it could mean for your home, let’s talk about how modified bitumen roofs in Florida get damaged.

Causes of Modified Bitumen Roof Damage

People tend to think of hurricanes as the things that damage roofs in Florida. While they certainly don’t help, there are plenty of factors damaging your roof every single day. The summer’s UV rays and humidity alone can leave your roof vulnerable to damage. If you find yourself needing modified bitumen roof repair services, it could be due to any of the following causes:

  • Foot Traffic: If you have a commercial structure, you may have chosen modified bitumen because it creates a walkable surface. While you can safely walk on modified bitumen, this will cause wear and tear that gradually weakens your roofing materials and can allow water into your roof.
  • UV Damage: If you notice cracks or splits in your modified bitumen, it’s probably due to UV damage. Over time, the sun’s rays cause your membrane to split and rupture. This is a common cause of leaking flat roofs.
  • Roof Punctures: Modified bitumen is generally resistant to punctures. However, dropping a sharp tool on your roof can create a hole in your roof membrane, as can storm debris thrown at high speeds by hurricane-force winds. These penetrations create opportunities for leaks and rot to enter your roof.
  • Pooling Water: If your roof can’t quickly remove water, it can start to eat away at your roof membrane. This issue is usually due to poor installation or wear and tear over the years.

As you can see, there are many ways for a modified bitumen roof to sustain damage in Florida. Regardless of the cause, though, the most important thing is to act quickly. Roof damage spreads quickly, especially where water is concerned. The best way to prevent damage and keep your roof repair costs low is to call in the professionals as soon as you notice a problem!

How Florida’s Top Roofers Handle Modified Bitumen Roof Repairs

How Florida’s Top Roofers Handle Modified Bitumen Roof Repairs

Because modified bitumen is such a popular roofing material, we’ve completed countless modified bitumen roof repair jobs across the state. With PITCH, we tailor each repair to the unique roof that we’re working on. That said, there is a lot of overlap when it comes to modified bitumen roof repair.

Often, a repair can be as simple as just patching up a damaged section of your roof membrane. This process involves applying a new section of modified bitumen over the old, damaged section and tightly sealing it to ensure that it’s flush with the rest of your roofing system. If you’re lucky and act quickly, you won’t need anything more than this simple roof repair.

However, not all mod bit repair jobs are that simple or easy. If water has had time to penetrate into your roofing system, the entire situation becomes a lot more complicated. That’s because your modified bitumen sits on top of wooden decking. When this decking gets damaged, it can threaten your roof’s structural integrity. To replace damaged decking, roofers will need to tear off and re-install part of your roof, which is a much more expensive and time-intensive repair.

Even for minor roof repairs, though, it’s usually not a good idea to repair your own roof. For one thing, you risk violating your warranties. It’s also just a good idea to leave roof repairs in the hands of professionals. While DIY roof repairs can save you money up front, you’ll end up paying a lot more if your patch isn’t 100% secure. If you’re concerned about roof repair costs, the best thing you can do is get a roofing quote.
