Waterproofing Your Roof Deck With A TPO Membrane: Pros, Cons, And Costs

Key Takeaways:

  • Your roof is vulnerable to leaks and damages, and waterproofing is an excellent way of protecting it.
  • A TPO membrane is a synthetic rubber that protects the roof from the elements.
  • The membrane creates a physical barrier between the elements and the roof deck.
  • TPO membrane installation costs depend on the kind of roof and the method applied.
  • TPO requires specialized installation techniques only used by professional roofers.

Property owners are always looking for ways to increase the value of their homes, and one way to do that is by waterproofing your roof deck. A TPO membrane can be a great way to do that, but there are some Pros and Cons to consider before you make a decision. Let’s take a look at the costs involved also.

What Is a TPO Membrane?

A TPO membrane is a synthetic rubber used as a waterproofing barrier. TPO membranes are often used on commercial and industrial rooftops because they effectively waterproof the roof deck.

How Does It Work?

TPO membranes create a physical barrier between the roof deck and the elements. When installed correctly, a TPO membrane will completely seal off the roof deck from water, wind, and UV rays. This helps to extend the roof’s life by protecting it from deterioration caused by exposure to the elements. 

The Benefits of TPO Membranes

  1. Hot-welded seam technology – TPO roofs are constructed using hot-welded seams, which makes repairs easy. Not to mention, the hot-welding process creates a watertight seal virtually impervious to leaks.
  2. UV and chemical-resistant – TPO roofs are also resistant to UV rays and chemicals, which means they’ll last longer and require less maintenance than other roofs.
  3. Damage-resistant – TPO roofs are also damage-resistant. This is because they’re made from a rigid, synthetic material. So, a TPO roof may be a good option if you live in an area with severe weather conditions.
  4. Durability and longevity – TPO roofs are incredibly durable and can last decades with proper care and maintenance. Many manufacturers offer 20-year or even lifetime warranties on their products.
  5. You can install a membrane over a concrete surface or plywood – Unlike other roofing materials, TPO membranes can be installed directly over a concrete surface or plywood. This makes them ideal for retrofit applications.

The Cons of TPO

  1. They’re costly. TPO roofs can cost up to twice as much as traditional asphalt roofs.
  2. The installation process is very complex and requires specialized training and equipment. You’ll need to hire a professional roofing contractor to install your TPO roof, which can add even more to the cost.
  3. TPO roofs require regular maintenance. You’ll need to regularly inspect your roof for any wear and tear and schedule professional roofing services to repair any damage.
  4. If your TPO roof is damaged, it can be challenging and expensive. This is because the membrane is heat welded together, which makes it challenging to access the damaged area without damaging the surrounding membrane. As a result, you may need to replace the entire roof, which can be costly.

The Cost of Installing a TPO Membrane

Before you break out the credit card and start shopping for materials, you’ll need to know how much this project will cost. To help you budget accordingly, we’ve put together a short guide on installing a TPO membrane to waterproof your roof deck.

Materials Costs

The first thing you’ll need to factor in is the costs of materials. For a standard-size roof deck (around 250 square feet), you can expect to spend anywhere from $6.50 to $8.00 per square foot installed. If your roof deck is on the larger side (500 square feet or more), you may get a discount from your contractor, bringing your costs down to closer to $6.00 per square foot.

Labor Costs

In addition to materials, you’ll also need to factor in labor costs. For a typical roof deck, you can expect to pay your contractor around $9.00 to $11.00 per square foot installed. This includes both the cost of labor and overhead expenses like insurance and licenses.

Why it’s Important to Waterproof Your Roof Deck

While there’s no denying the significance of a TPO membrane, the need for waterproofing the roof deck is enough to convince property owners to revamp their roofs. Water and storm damage can leave behind leaks that can damage the property, and weatherproofing the deck is your chance to secure your roofing structure. Here’s why it’s essential to weatherproof the roof deck.

1. Leaks

Leaks can cause all sorts of damage to your home, from ruined carpets and furniture to mold and mildew. Not to mention, they’re just plain annoying. No one wants to be constantly mopping up water every time it rains.

2. Interior Damage

Leaks can damage your home’s interior, specifically ceilings, and walls. If water seeps through cracks or gaps in your roof deck, it can cause stains and discoloration on your ceiling or walls. In extreme cases, leaks can even cause structural damage to your home. So don’t risk it – get your roof deck waterproofed!

3. Structural Damage

Speaking of structural damage, did you know that waterproofing your roof deck can also help prevent it? That’s right – if water gets into the pores of the concrete or other porous materials, it can cause the material to expand and crack. Over time, this can weaken the structure of your home and lead to costly repairs. Waterproofing is a barrier to prevent water from seeping into these materials and causing damage.

4. Mold

Mold spores are everywhere – in the air, on surfaces, etc. When mold spores come into contact with moisture, they can multiply quickly. And once mold starts growing in your home, getting rid of it can be very difficult (and expensive). So why take the risk? Waterproofing your roof deck will help create a barrier against mold growth.

So, there you have all the reasons for waterproofing your roof deck with a TPO membrane in North Port.
