When it comes to choosing the right roofing system for your home or commercial property, the decision can be overwhelming. There are several roofing options available, but two of the most common choices are membrane roofing and traditional roofing. Both have their advantages and disadvantages, but which one is better for your needs?
In this blog post, we’ll break down the key differences between membrane roofing and traditional roofing, so you can make an informed decision. Whether you’re in Medford, OR, or nearby areas like Ashland, Central Point, Eagle Point, Grants Pass, or Roseburg, this guide will help you determine which roofing system is best suited for your building.
What is Membrane Roofing?
Membrane roofing is a modern roofing system typically used for flat or low-slope roofs. It consists of a continuous layer of material, such as TPO (thermoplastic olefin), EPDM (ethylene propylene diene monomer), or PVC (polyvinyl chloride), which forms a waterproof membrane that covers the entire roof. This type of roofing is most commonly seen in commercial buildings but is becoming increasingly popular in residential properties with flat or low-pitched roofs.
Membrane roofing is known for its durability, energy efficiency, and ease of installation. It provides a seamless barrier against water infiltration, which makes it ideal for preventing leaks and water damage.
What is Traditional Roofing?
Traditional roofing, on the other hand, refers to more conventional roofing systems, such as asphalt shingles, wood shakes, or tile roofing. These materials have been used for centuries and remain the most common roofing choice for both residential and commercial buildings. Traditional roofs are typically pitched, which allows rainwater to flow off naturally.
Asphalt shingles are the most popular form of traditional roofing in residential properties, while wood shakes and tile roofing are often used for aesthetic purposes or in areas with specific weather conditions. Traditional roofing is known for its versatility, wide variety of material options, and classic aesthetic appeal.
Membrane Roofing vs. Traditional Roofing: Key Differences
1. Installation Process
One of the key differences between membrane roofing and traditional roofing is the installation process. Membrane roofing is installed as a single layer of material that is either adhered, mechanically attached, or ballasted to the roof’s surface. The installation process is typically faster and requires fewer materials than traditional roofing.
In contrast, traditional roofing often requires multiple layers, such as underlayment, shingles, and additional sealants. This can make the installation process more time-consuming and labor-intensive, particularly for roofing systems like wood shakes or tile roofs.
Winner: Membrane roofing tends to have a quicker, less complex installation process, which may save you both time and money.
2. Durability and Lifespan
Both membrane roofing and traditional roofing are durable, but they have different lifespans and performance characteristics.
Membrane roofing is known for its long-lasting durability. Materials like EPDM and TPO can last anywhere from 20 to 50 years, depending on the climate and the level of maintenance. Membrane roofs are highly resistant to weather elements, UV radiation, and water, making them ideal for areas with harsh conditions or frequent rainfall.
On the other hand, traditional roofing systems also have impressive durability, but their lifespans tend to be shorter than that of membrane roofs. Asphalt shingles, for instance, typically last 15 to 25 years, while tile and wood shake roofs can last much longer—up to 50 years or more—depending on maintenance and the quality of the materials.
Winner: Membrane roofing wins in terms of consistent durability and lower maintenance. However, tile and wood shake roofing can last longer if well-maintained.
3. Energy Efficiency
Membrane roofing systems offer excellent energy efficiency, particularly TPO and PVC membranes, which reflect sunlight and reduce heat absorption. This reflective property helps keep the building cooler, reducing the need for air conditioning in warm climates. As a result, you can save money on cooling costs and make your building more energy-efficient.
Traditional roofing systems, particularly asphalt shingles, tend to absorb heat, which can raise the internal temperature of the building. While reflective asphalt shingles are available, they are generally not as effective as membrane roofs at keeping temperatures down. Tile roofs, however, are a good alternative, as they have natural insulating properties and can help keep buildings cool in hot climates.
Winner: Membrane roofing systems like TPO and PVC offer superior energy efficiency in warmer climates.
4. Waterproofing and Leak Prevention
When it comes to waterproofing, membrane roofing offers an advantage. Because it’s installed as a continuous, seamless layer, membrane roofing prevents water from seeping through gaps or joints, which is a common issue with traditional roofing systems. The lack of seams makes membrane roofing particularly effective at preventing leaks, especially in flat or low-slope roofs.
In contrast, traditional roofing systems often rely on overlapping materials, such as shingles or tiles, which can create potential weak points where water can infiltrate. While modern roofing materials like asphalt shingles and tiles are designed to be waterproof, they can still be vulnerable to leaks, especially as they age and the materials start to deteriorate.
Winner: Membrane roofing, with its seamless construction, provides superior waterproofing and leak prevention.
5. Cost
Cost is a critical factor when choosing between membrane roofing and traditional roofing.
Membrane roofing is generally more expensive to install than traditional roofing systems, mainly because of the materials used and the expertise required for installation. However, due to its durability and low maintenance, it can offer significant long-term savings, particularly in terms of repair and replacement costs.
Traditional roofing systems, such as asphalt shingles, are generally less expensive to install upfront. They are often a more affordable option for homeowners with budget constraints. However, because they tend to require more frequent repairs or replacements, the long-term costs can add up.
Winner: Traditional roofing is more affordable upfront, but membrane roofing can save money over time due to its lower maintenance needs and longer lifespan.
Pros and Cons of Membrane Roofing and Traditional Roofing
Membrane Roofing Pros:
- Superior waterproofing and leak prevention
- Longer lifespan (20-50 years)
- Better energy efficiency in warmer climates
- Quicker and easier installation
- Minimal maintenance
Membrane Roofing Cons:
- Higher upfront cost
- Not as widely available in residential markets
- Limited aesthetic variety
Traditional Roofing Pros:
- Lower upfront cost
- Wide variety of materials and styles (asphalt, wood, tile)
- Long-lasting if well-maintained (up to 50 years for some materials)
- Classic aesthetic appeal
Traditional Roofing Cons:
- Requires more maintenance and repairs over time
- Less energy-efficient, especially in hot climates
- Can be more vulnerable to leaks, especially as the roof ages
Conclusion
Both membrane roofing and traditional roofing have their advantages, and the choice ultimately depends on your specific needs and budget. If you are looking for a low-maintenance, durable, and energy-efficient option, especially for flat or low-slope roofs, membrane roofing is the way to go. However, if aesthetic appeal and a more affordable upfront cost are more important, traditional roofing may be a better choice.
