Introduction: Rubber Roofing vs. Felt Roofing
Choosing the right roofing material is a crucial decision for any homeowner, impacting both the aesthetic appeal and the longevity of your property. This comparison guide will delve into two popular options: rubber roofing and felt roofing, examining their key features, costs, and lifespans to help you make an informed choice. We’ll explore the advantages and disadvantages of each to clarify which might be the best fit for your specific needs and budget.
Rubber roofing, also known as EPDM (ethylene propylene diene monomer) roofing, is a synthetic rubber membrane that’s highly durable and resistant to extreme weather conditions. Felt roofing, conversely, is a more traditional roofing material composed of layers of asphalt-saturated felt paper, often topped with a granular surface for protection. While both offer protection from the elements, their composition, installation, and long-term performance differ significantly.
Initial Costs of Rubber and Felt Roofing
The initial cost of roofing materials is a major factor influencing homeowners’ decisions. Rubber roofing typically has a higher upfront cost compared to felt roofing. The price difference stems from the material itself, as rubber membranes are more expensive to produce than felt. Furthermore, the installation process for rubber roofing often requires more specialized labor, further increasing the overall expense. A typical 1000 sq ft rubber roof installation might cost between $8,000 and $15,000, while a felt roof installation for the same area could range from $3,000 to $7,000, depending on factors like location, labor costs, and the complexity of the roof structure. These figures are estimates and can vary considerably. For example, a simple, low-pitched roof will generally cost less than a complex, multi-layered roof.
Lifespan Expectations of Rubber and Felt Roofing
The longevity of a roof is paramount. Rubber roofing systems are renowned for their exceptional durability and can last for 30 to 50 years or even longer with proper maintenance. This extended lifespan often outweighs the higher initial investment. In contrast, felt roofing has a considerably shorter lifespan, typically ranging from 10 to 20 years, depending on climate and maintenance. Factors such as intense sun exposure, heavy rainfall, and extreme temperature fluctuations can significantly reduce the lifespan of a felt roof. A well-maintained felt roof might reach the upper end of this range, but regular inspections and repairs are essential to prolong its life.
Material Properties
Understanding the material properties of rubber and felt roofing is crucial for assessing their durability and longevity. These properties directly impact the roofing system’s lifespan and its ability to withstand various environmental stressors. This section will compare the durability and longevity of both materials, considering their resistance to weather conditions and UV degradation.
Durability and Longevity of Rubber Roofing
Rubber roofing, typically EPDM (ethylene propylene diene monomer) or TPO (thermoplastic polyolefin), exhibits excellent durability due to its inherent flexibility and resistance to stretching. This allows it to accommodate thermal expansion and contraction, minimizing the risk of cracking or tearing, even under significant temperature fluctuations. Its resistance to punctures and tears also contributes to its long lifespan. In areas with heavy snowfall, the flexibility of rubber roofing prevents damage from ice dams and snow loads. Furthermore, rubber roofing is highly resistant to many chemicals and pollutants found in the environment, further enhancing its longevity. A well-maintained rubber roof can easily last 30-50 years, sometimes even longer, depending on the quality of installation and the specific climate. For example, a rubber roof installed in a relatively mild climate with minimal exposure to extreme weather conditions might last closer to the upper end of that range.
Durability and Longevity of Felt Roofing
Felt roofing, also known as asphalt roofing, is significantly less durable than rubber roofing. Its lifespan is heavily influenced by climate conditions, primarily exposure to sunlight, moisture, and temperature fluctuations. In regions with intense sunlight, the asphalt in felt roofing can become brittle and crack, reducing its lifespan. Prolonged exposure to moisture can lead to degradation and the growth of mold or algae, further compromising the roof’s integrity. While advancements in felt roofing technology have improved its durability, the expected lifespan is generally much shorter than that of rubber roofing, typically ranging from 15 to 20 years. A felt roof in a harsh desert climate might only last 10-15 years, whereas one in a milder, less sunny climate could approach the upper end of the range.
UV Degradation Resistance
Both rubber and felt roofing are susceptible to UV degradation, but to varying degrees. Felt roofing, with its asphalt composition, is particularly vulnerable to UV rays, which can cause the asphalt to dry out, crack, and become brittle. This leads to a significant reduction in the roof’s lifespan and increased risk of leaks. Rubber roofing, on the other hand, possesses considerably better UV resistance due to the inherent properties of the rubber materials. While some degradation can still occur over time, it’s significantly less pronounced than in felt roofing. The addition of UV stabilizers during the manufacturing process further enhances the UV resistance of many rubber roofing materials. Therefore, rubber roofing generally maintains its structural integrity and waterproofing capabilities for a longer period under prolonged sun exposure compared to felt roofing.
Installation Process
The installation process for both rubber and felt roofing systems significantly impacts the overall cost and longevity of the roof. Understanding the complexities and time requirements for each is crucial for informed decision-making.

Rubber Roofing Installation
Rubber roofing, typically EPDM (ethylene propylene diene monomer) or TPO (thermoplastic polyolefin), is installed using a relatively straightforward process. The process generally involves cleaning the roof surface, applying adhesive (for some systems), and carefully laying out the rubber membrane. Seams are then sealed using specialized tape or adhesive. Proper flashing around chimneys, vents, and other penetrations is crucial for preventing leaks.
Tools commonly used include utility knives, measuring tapes, rollers, and adhesive applicators. Specialized tools might be needed for complex roofing designs. Experienced installers can complete the process efficiently, paying close attention to detail to ensure a watertight seal.
Felt Roofing Installation
Felt roofing, often asphalt-saturated felt, requires a more layered approach. Multiple layers of felt are applied, each overlapping the previous one to create a water-resistant barrier. Each layer is typically secured with nails or staples. This process is labor-intensive and requires careful attention to overlapping and sealing to prevent water penetration. Similar to rubber roofing, proper flashing around penetrations is essential.
Tools needed include hammers, roofing nails or staples, a utility knife, and potentially a roofing cement for added sealing. The installation process is generally more time-consuming and requires a higher level of skill to ensure proper overlapping and sealing of each layer.
Installation Time and Complexity Comparison
The following table compares the installation time, complexity, and required skill level for rubber and felt roofing. These are estimates and can vary based on roof size, complexity, and installer experience.

Over the lifespan of the roof, rubber roofing generally proves to be more cost-effective in terms of maintenance. While the initial cost of rubber roofing might be higher than felt roofing, the reduced frequency of repairs and lower cost of minor maintenance often result in significant long-term savings. For example, a homeowner might spend $50-$100 annually on cleaning and minor repairs for rubber roofing, while felt roofing could require $100-$300 or more annually, depending on the climate and the roof’s condition. In cases of major damage, the repair costs for felt roofing can be considerably higher than those for rubber roofing due to the more extensive nature of the repairs often needed. Therefore, while the initial investment may be different, the cumulative maintenance cost over 20-30 years often favors rubber roofing.
Environmental Impact
Choosing between rubber and felt roofing involves considering the environmental implications throughout the product lifecycle, from material sourcing and manufacturing to disposal and recycling. Both options have inherent environmental costs and benefits, and the optimal choice depends on various factors, including specific product composition and regional recycling infrastructure.
The environmental impact of rubber and felt roofing materials differs significantly. Rubber roofing, often made from recycled tires or synthetic rubber, can incorporate reclaimed materials, reducing the demand for virgin resources. However, the manufacturing process of synthetic rubber can be energy-intensive and generate emissions. Felt roofing, traditionally made from asphalt and fiberglass, relies heavily on fossil fuels during production. The asphalt component contributes to greenhouse gas emissions, while the fiberglass manufacturing process can involve the release of harmful substances.
Manufacturing Processes and Emissions
The manufacturing processes for both rubber and felt roofing materials contribute to their overall environmental impact. Rubber roofing, while potentially utilizing recycled materials, still requires energy for processing and manufacturing. The production of synthetic rubber, in particular, can generate volatile organic compounds (VOCs) and other air pollutants. Felt roofing, being heavily reliant on asphalt and fiberglass, presents a greater challenge. Asphalt production is known to release significant greenhouse gases, including carbon dioxide and methane. Fiberglass manufacturing also involves energy consumption and potential emissions of harmful substances. A life cycle assessment (LCA) comparing specific products would provide a more precise comparison of these emissions. For example, an LCA might reveal that a particular rubber roofing product with a high recycled content has a lower carbon footprint than a specific felt roofing product.
Recyclability and End-of-Life Options
The recyclability and end-of-life options for rubber and felt roofing differ considerably. Rubber roofing, particularly those made from recycled materials, may have greater potential for recycling or repurposing at the end of their lifespan. Some manufacturers offer take-back programs or work with recycling facilities to process old roofing membranes. However, the recycling infrastructure for rubber roofing is still developing, and not all rubber roofing materials are readily recyclable. Felt roofing presents more significant challenges in terms of recycling. The composite nature of asphalt and fiberglass makes separation and recycling difficult. Landfilling is often the default end-of-life option for felt roofing, contributing to waste accumulation. However, some advancements are being made in utilizing recycled asphalt in road construction.
Potential Environmental Benefits and Drawbacks
Rubber roofing can offer environmental benefits through the utilization of recycled materials, potentially reducing the demand for virgin resources and landfill waste. However, the energy intensity of synthetic rubber production and potential for emissions remain concerns. Felt roofing’s primary environmental drawback is its reliance on fossil fuels and the difficulty in recycling. The contribution to landfill waste and greenhouse gas emissions during manufacturing are significant. However, improvements in asphalt formulation and potential for recycled asphalt usage are mitigating some of these concerns. The overall environmental performance of each roofing type is highly dependent on the specific product composition, manufacturing processes, and end-of-life management practices.
Cost-Effectiveness
Choosing between rubber and felt roofing involves careful consideration of long-term costs. While initial material costs might favor felt, the overall expense over the roofing’s lifespan needs thorough evaluation. This includes not only the purchase price but also maintenance, repairs, and eventual replacement. Total cost of ownership provides a more comprehensive picture for informed decision-making.
The total cost of ownership (TCO) accounts for all expenses associated with a roofing system throughout its operational life. This encompasses the initial investment in materials and labor, ongoing maintenance requirements, potential repair costs, and the eventual replacement cost. For both rubber and felt roofing, these factors can significantly influence the overall financial impact.
Cost Comparison of Rubber and Felt Roofing

| Average Lifespan (years) | 30-50 | 10-15 |
| Annual Maintenance Cost (per square foot) | $0.10 – $0.50 | $0.25 – $1.00 |
| Repair Costs (estimated over lifespan) | Low (infrequent) | Moderate to High (more frequent) |
| Replacement Cost (per square foot) | $5 – $12 (after 30-50 years) | $2 – $5 (after 10-15 years) |
Example: Consider a 1000 square foot roof. The initial cost of rubber roofing might be $10,000 – $22,000 (materials and labor), while felt roofing could cost $7,000 – $15,000. However, over 30 years, the rubber roof will likely require less maintenance and fewer repairs than the felt roof, which would need replacement at least once during that period. The cumulative cost difference might favor rubber roofing despite its higher upfront investment.
Factors Affecting Total Cost of Ownership
Several factors influence the final cost of each roofing type. These variables should be carefully considered during the planning stage.
Material quality significantly impacts both initial and long-term costs. Higher-quality materials generally last longer, requiring less frequent maintenance and repairs, thus reducing the overall TCO. Similarly, the complexity of the roof structure and the experience of the installation crew influence labor costs. A steeper or more complex roof will require more labor and potentially increase the overall expense. Finally, geographical location affects material pricing and labor rates, influencing the total cost of ownership.
Aesthetics and Appearance
The aesthetic appeal of a roof is a crucial consideration in any home improvement project. Both rubber and felt roofing offer distinct visual characteristics that impact the overall look and feel of a building, influencing its curb appeal and architectural harmony. Understanding these differences is essential for making an informed decision.
Rubber roofing, while functional, presents a more modern and sleek aesthetic compared to felt roofing. Its smooth surface provides a clean, unblemished look, contributing to a contemporary feel.
Rubber Roofing Aesthetics
Rubber roofing offers a range of color options, typically in dark shades like black, brown, and dark gray, although some manufacturers offer lighter colors. These colors are generally consistent and uniform across the roof surface, creating a clean, modern look. The material itself is smooth, creating a visually unblemished surface, often preferred in contemporary and minimalist architectural styles. The absence of visible seams or textures, unlike felt roofing, contributes to this sleek appearance. For example, a low-sloped modern home with clean lines would benefit aesthetically from a rubber roofing system.
Felt Roofing Aesthetics
Felt roofing, in contrast, presents a more textured and less uniform appearance. The individual sheets of felt are visible, creating a slightly rougher surface texture. While often available in darker colors, the color may not be as consistently uniform as rubber roofing due to the overlapping sheets and potential for weathering variations. The visible seams and textures add a more traditional or rustic aesthetic. This type of roofing is often more suited to homes with more traditional architectural styles, where the texture might blend more harmoniously with other design elements. For instance, a Victorian-style home with intricate detailing might find felt roofing visually more compatible than a sleek rubber roofing system.
Suitability for Architectural Styles
The choice between rubber and felt roofing significantly impacts the overall aesthetic harmony of a building. Rubber roofing’s sleek, uniform appearance complements modern, minimalist, and contemporary architectural styles. Its clean lines and lack of visible texture create a visually cohesive look with modern homes that emphasize simplicity and geometric shapes. Conversely, felt roofing’s textured and slightly rougher surface is more suitable for traditional, rustic, and historical architectural styles.

The choice, therefore, should be carefully considered within the context of the existing building’s architectural style and design elements to ensure a visually pleasing and cohesive outcome.
Water Resistance and Leak Prevention
Choosing between rubber and felt roofing hinges significantly on their respective abilities to withstand water damage and prevent leaks. Both materials offer a degree of water resistance, but their mechanisms and effectiveness differ considerably. Understanding these differences is crucial for making an informed decision based on the specific needs of a roofing project.
Rubber roofing, typically EPDM (ethylene propylene diene monomer) or TPO (thermoplastic polyolefin), excels at water resistance due to its inherent properties. The material is highly impermeable, meaning water cannot easily penetrate its surface. Its seamless nature, often achieved through heat-welding or adhesive bonding, eliminates many potential points of leakage common in felt roofing systems. Furthermore, rubber membranes are highly elastic and can expand and contract with temperature fluctuations without cracking or losing their watertight seal, a crucial factor in preventing leaks over time.
Rubber Roofing Water Resistance Mechanisms
Rubber roofing’s resistance to water damage stems from its dense, non-porous structure. The polymer chains in EPDM and TPO create a tightly bound, continuous membrane that effectively repels water. This is unlike felt, which relies on multiple layers and saturation to achieve water resistance. Proper installation, including the use of appropriate adhesives and sealing techniques at seams and edges, further enhances the watertight integrity of a rubber roof. The flexibility of the material allows it to accommodate minor roof movement and expansion without compromising its waterproof seal.
Felt Roofing Water Resistance Mechanisms
Felt roofing, traditionally made from asphalt-saturated organic or fiberglass mats, achieves water resistance through a layered approach. Multiple layers of felt are applied, overlapping each other to create a barrier against water penetration. Asphalt saturation provides waterproofing properties, but it is susceptible to degradation over time due to UV exposure and weathering. The layers are further protected by a granular surfacing, such as gravel or mineral chips, which provides additional protection against UV damage and enhances the overall durability. However, even with multiple layers, the potential for water penetration exists at seams and overlaps, especially if the installation is not meticulous.
Comparison of Water Penetration Prevention
In terms of preventing water penetration, rubber roofing generally demonstrates superior performance compared to felt roofing. The seamless nature of rubber membranes minimizes potential leak points, while the inherent impermeability of the material provides a robust barrier against water. Felt roofing, while effective when properly installed, is more susceptible to leaks due to its layered structure and reliance on asphalt saturation, which can degrade over time. Consequently, rubber roofing often requires less maintenance and is associated with a longer lifespan, reducing the likelihood of costly repairs or replacements due to water damage.

Choosing a roofing material involves careful consideration of fire safety, as roofing systems are often exposed to external ignition sources. Both rubber and felt roofing materials present different levels of fire resistance and associated safety considerations. Understanding these differences is crucial for ensuring building compliance and occupant safety.
Rubber roofing, typically made from EPDM (ethylene propylene diene monomer) or TPO (thermoplastic polyolefin), generally exhibits better fire resistance than felt roofing. This is due to the inherent properties of the materials themselves. However, it’s important to note that no roofing material is completely fireproof.
Fire Resistance Properties of Rubber and Felt Roofing
Rubber roofing materials, like EPDM and TPO, possess a higher resistance to ignition and slower burning rate compared to felt roofing. They typically have a Class A fire rating according to many building codes, indicating superior fire resistance. Felt roofing, on the other hand, is highly flammable and typically receives lower fire ratings, often Class C. This difference stems from the composition of the materials: rubber roofing is a synthetic polymer, while felt roofing is composed of organic fibers that are easily combustible. The presence of asphalt saturation in felt roofing further contributes to its flammability.
Fire Safety Considerations
While rubber roofing offers better fire resistance, both types require careful installation to minimize fire risks. Proper ventilation in the attic space is crucial to prevent the buildup of flammable gases. Furthermore, nearby combustible materials should be kept at a safe distance from the roof. For felt roofing, additional fire safety measures, such as the application of fire-retardant treatments, may be necessary to meet local building codes. Regular inspections and maintenance are also important for both types of roofing to detect and address any potential fire hazards, such as damaged areas or accumulated debris.
Relevant Building Codes and Safety Regulations
Building codes and safety regulations regarding fire resistance vary by location. However, most jurisdictions mandate minimum fire resistance ratings for roofing materials based on factors like building occupancy and construction type. These regulations are often outlined in model building codes, such as the International Building Code (IBC), which many local jurisdictions adopt or adapt. Compliance with these codes is crucial to ensure the safety of the building and its occupants. Local fire departments and building inspectors can provide guidance on specific requirements and ensure proper installation.
