Rolled Roofing Material Types: A Comprehensive Guide for American Homeowners
Rolled roofing remains a popular and cost-effective solution for many homeowners and businesses across the United States. Known for its ease of installation and affordability, rolled roofing is ideal for low-slope roofs. This guide covers the most common rolled roofing material types, highlighting their benefits, applications, and key characteristics to help property owners make informed decisions.

| Modified Bitumen | Enhanced elasticity, UV resistant, durable | Flat roofs, commercial buildings | 10-20 years |
| Rubberized Asphalt | Flexible, highly waterproof, withstands temperature changes | Roofs exposed to harsh climates | 15+ years |
| Metal Coil Roofing Rolls | Durable, lightweight, corrosion-resistant | Industrial and residential low-pitch roofs | 20-40 years |
| Plastic and PVC Rolled Roofing | UV resistant, fire-resistant, easy maintenance | Commercial buildings with flat roofs | 15-30 years |
Common Types of Rolled Roofing Materials
Rolled roofing materials are designed primarily for flat or low-sloping roofs and generally come in large rolls for easy transportation and installation. Each type offers unique properties that suit different environments and budgets.
Asphalt-Based Rolled Roofing
One of the most common rolled roofing options, asphalt-based rolled roofing is composed of asphalt-saturated felt or fiberglass mats. It is coated with mineral granules to improve durability and resistance to weather. This material is popular because it is cost-efficient and straightforward to install, making it ideal for temporary or budget-conscious roofing projects.
Its lifespan ranges from 5 to 10 years, depending on climate and maintenance. Asphalt rolled roofing is best suited for small structures such as sheds, garages, and low-slope residential roofs.
Modified Bitumen Rolled Roofing
Modified bitumen roofing is an advancement of traditional asphalt roofing, incorporating modifiers like SBS (styrene-butadiene-styrene) or APP (atactic polypropylene) to create a material that’s more elastic, UV resistant, and weather tolerant. This flexibility helps resist cracking in colder climates and heat deformation during summer.
Modified bitumen is widely used on commercial and residential roofs with low slopes due to its higher durability and enhanced weatherproof qualities. It typically lasts between 10 and 20 years and can be adhered using heat or cold self-adhering methods.
Rubberized Asphalt Rolled Roofing
This type includes additional rubber polymers to asphalt, which confers superior elasticity and sealing capabilities. Rubberized asphalt rolled roofing is particularly effective at accommodating roof movement, sealing around joints and fasteners, and providing waterproof protection.
Its high flexibility makes it suitable for roofs experiencing frequent temperature fluctuations, such as in northern states. Typical durability is around 15 years or more, making it an excellent mid-range option for residential applications.
Metal Coil Roofing Rolls
Metal coil roofing is made from rolls of thin metal sheets, usually steel or aluminum, coated with rust-resistant finishes. It combines durability with lightweight properties, making it a superior rolled roofing alternative.
Metal roofing coils are often used for industrial buildings, agricultural structures, and homes requiring long-lasting protection. They provide excellent resistance to wind, hail, and fire, with a lifespan ranging from 20 to 40 years. Additionally, metal roofing is recyclable and environmentally friendly.
Plastic and PVC Rolled Roofing
Plastic-based rolled roofing materials, including PVC (polyvinyl chloride), are designed for durability and ease of maintenance. They are naturally UV resistant, fire-retardant, and waterproof, making them popular on commercial flat roofs.
Though more expensive than traditional asphalt rolls, PVC roofing offers a good balance of longevity (15-30 years) and performance. They also tend to have a reflective surface, which can improve energy efficiency by reducing heat absorption.
Factors to Consider When Choosing Rolled Roofing Materials
Choosing the right rolled roofing material depends on several factors including climate, roof slope, budget, and intended longevity. Below are key aspects to evaluate:
- Climate and Weather Resistance: Roofs in harsh climates need materials that can handle UV rays, freeze-thaw cycles, and heavy rainfall.
- Budget Constraints: Asphalt rolls are affordable but may require frequent replacements, whereas metal and modified bitumen offer longer service life at a higher upfront cost.
- Simplicity of Installation: Some rolled roofing comes with self-adhesive backing, while others require torching or professional installation.
- Maintenance Requirements: Materials like metal and PVC require less frequent upkeep compared to asphalt-based rolls.
- Environmental Impact: Metal roofs offer recyclability and energy-saving benefits that may appeal to eco-conscious homeowners.
Comparison Table of Rolled Roofing Types
| Material | Cost Range (per sq ft) | Installation Method | Typical Lifespan | Advantages | Disadvantages |
|---|---|---|---|---|---|
| Asphalt-Based | $0.70 – $1.50 | Self-adhered or nailed | 5-10 years | Low cost, easy to install | Short lifespan, less durable |
| Modified Bitumen | $3.00 – $5.00 | Heat applied or self-adhered | 10-20 years | Flexible, weather resistant | Requires professional installation |
| Rubberized Asphalt | $2.50 – $4.00 | Self-adhered | 15+ years | Highly flexible and waterproof | Moderate cost, limited color options |
| Metal Coil | $4.00 – $7.00 | Snapped/fastened to roof deck | 20-40 years | Durable, recyclable | Higher upfront cost, requires insulation |
| Plastic/PVC | $3.50 – $6.00 | Self-adhered or mechanically fastened | 15-30 years | UV resistant, fire retardant | Costly, potential for shrinking |
How to Install Rolled Roofing: Key Steps
Though installation methods vary slightly based on material type, the following general steps apply to most rolled roofing systems:
- Prepare the Roof Surface: Clean and repair the roof deck ensuring it is dry and smooth.
- Install Underlayment: Apply a moisture barrier or felt paper to improve waterproofing.
- Roll Out the Roofing Material: Begin at the lowest edge of the roof, rolling out in overlapping layers.
- Secure the Material: Fasten the edges with nails or use heat/self-adhesive methods as per material specification.
- Seal the Seams: Apply roofing cement or seam tape to ensure water tightness.
- Inspect and Maintain: Regularly check for cracks, lifting edges, or punctures and address repairs promptly.
Benefits of Rolled Roofing for American Homes
Rolled roofing presents several advantages that cater well to typical American residential structures, especially in suburban and rural areas:
- Affordability: It is less expensive compared to traditional shingle or tile roofing.
- Quick Installation: Roofing projects can be completed rapidly, minimizing labor costs.
- Lightweight: Reduced structural stress on buildings, important for older homes.
- Versatility: Available in various types adapted to different climates and roof designs.
- Temporary Solution: Ideal for quick fixes or secondary structures awaiting more extensive roofing projects.
Maintenance Tips for Prolonging Rolled Roof Life
Maintaining rolled roofing properly can significantly extend its lifespan and performance. Consider the following best practices:
- Regularly clean debris, leaves, and dirt to prevent moisture buildup.
- Inspect the roof after storms or strong winds for loose seams or punctures.
- Reapply roofing cement on seams and around flashing annually.
- Trim nearby tree branches to avoid damage from falling limbs or rub abrasion.
- Ensure gutters and downspouts are free-flowing to prevent water pooling.
Environmental Impact and Sustainability Considerations
Traditional asphalt rolled roofing is petroleum-based and has a limited environmental lifespan. However, newer materials such as metal and PVC rolls offer improved sustainability through longer lifespans, recyclability, and energy-efficient properties.
Homeowners interested in eco-friendliness should weigh the benefits of metal coil roofing or advanced polymer roofing options to reduce landfill waste and energy use.
Summary
Choosing the right rolled roofing material involves balancing cost, durability, climatic conditions, and installation preferences. Asphalt remains the budget-friendly choice, while modified bitumen and metal options provide longevity and resilience. Understanding these types equips homeowners and contractors with the knowledge to select a roofing system that meets both functional demands and financial plans effectively.
