Rolled roofing is a popular, cost-effective solution for covering low-slope roofs, mainly on sheds, garages, and other small-scale structures. Offering easy installation and a variety of material options, rolled roofing provides an alternative to traditional shingles or tiles. This article explores different types of rolled roofing materials, their characteristics, and best use cases to help property owners make informed roofing decisions.
| Type of Rolled Roofing | Material Composition | Typical Uses | Durability | Cost Range |
|---|---|---|---|---|
| Asphalt Roll Roofing | Fiberglass or organic felt saturated with asphalt | Low-slope residential roofs, sheds | 5-10 years | Low |
| Modified Bitumen | Asphalt combined with modifiers like APP or SBS | Commercial buildings, low-slope roofs | 10-20 years | Moderate |
| Rubberized Asphalt | Asphalt with added rubber polymers | Roofs requiring enhanced flexibility and waterproofing | 15-25 years | Moderate to High |
| TPO and EPDM Roofing Membranes | Synthetic single-ply membranes | Commercial and residential flat roofs | 20-30 years | High |
| Aluminum or Metal-Coated Rolls | Metal sheets rolled out in long strips | Industrial roofing, agricultural buildings | 20-40 years | Moderate to High |
Asphalt Roll Roofing
Asphalt rolled roofing is the most widely used type due to its affordability and ease of installation. Made from organic or fiberglass felt saturated with asphalt, it provides a waterproof layer to protect roofs with gentle slopes. This material typically comes in 36-inch wide rolls, making it quick to lay down.
Asphalt rolled roofing offers adequate protection for low-traffic, steep-to-low slope roofs and temporary coverings. However, it tends to wear out in 5 to 10 years under harsh weather conditions, so it is best suited for smaller structures or as a budget-friendly option.
Modified Bitumen Rolled Roofing
Modified bitumen roofing enhances traditional asphalt roofing with synthetic polymers such as Atactic Polypropylene (APP) or Styrene-Butadiene-Styrene (SBS). These additives increase elasticity, UV resistance, and durability. Modified bitumen is typically installed in rolls and is often reinforced with polyester or fiberglass membranes.
This roofing type is common for commercial buildings and flat or low-slope residential roofs. It can last 10 to 20 years, providing puncture resistance and good waterproofing under extreme weather. Its flexibility makes it ideal for roofing surfaces with foot traffic or equipment installations.
Rubberized Asphalt Rolled Roofing
Rubberized asphalt roofing incorporates additional rubber polymers to increase flexibility and waterproofing benefits. It is especially useful in climates with significant thermal expansion and contraction.
This material is suitable for roofing surfaces that require extra flexibility and protection from water infiltration. Often featuring a smooth or granulated surface, rubberized asphalt roofing can last between 15 and 25 years. However, its cost tends to be higher compared to standard asphalt rolls.
Single-Ply Membrane Roofing: TPO and EPDM
Though typically available as sheets rather than rolls, Thermoplastic Olefin (TPO) and Ethylene Propylene Diene Monomer (EPDM) membranes are sometimes categorized under rolled roofing options due to their flexible, rollable nature. These synthetic materials offer enhanced UV resistance, longevity, and ease of installation.
TPO membranes reflect sunlight effectively, reducing heat buildup, making them a popular choice for flat commercial and residential rooftops. EPDM, a rubber-based product, is prized for its durability and water resistance. Both types last 20 to 30 years and come in large rolls that are heat-welded or glued to the rooftop.
Metal-Coated and Aluminum Rolled Roofing
Metal-coated rolls, including aluminum rolls, offer a more durable and weather-resistant option. These come in long strips that are rolled for transport convenience and applied directly on roofing substrates.
Metal rolled roofing is common in industrial, agricultural, and some residential applications, especially when longevity and strength are priorities. Aluminum rolls resist corrosion and can last 20 to 40 years. They are also valued for their fire resistance and minimal maintenance requirements.
Choosing the Right Rolled Roofing for Your Needs
Selecting the appropriate rolled roofing depends on factors like roof slope, climate, budget, and intended roof lifespan. While asphalt rolls are inexpensive and simple to install, they may not withstand heavy weather as well as modified bitumen or synthetic membranes.
- For budget-conscious homeowners with minor roofing needs, asphalt roll roofing remains a reliable choice.
- Commercial properties requiring enhanced durability should consider modified bitumen or synthetic membranes like TPO or EPDM.
- Metal or aluminum rolls offer long-lasting, low-maintenance coverage for larger or industrial roofs.
Maintenance and Longevity of Rolled Roofing
Proper upkeep can extend the lifespan of rolled roofing materials significantly. Regular inspections help identify issues such as tears, blistering, and pooling water, which can compromise the roof’s integrity.
Many rolled roofing materials benefit from routine cleaning of debris and application of protective coatings to enhance waterproofing and UV resistance. Maintenance is crucial, especially for asphalt-based roll roofing, which typically has shorter durability without care.
Environmental Considerations and Innovations in Rolled Roofing
Today’s rolled roofing products increasingly incorporate environmentally friendly features. Cool roofing technologies, such as reflective coatings used in TPO membranes, help reduce energy consumption by lowering building temperatures during summer.
Manufacturers are also advancing sustainable materials, using recycled content and reducing harmful emissions during the production and installation processes. These innovations improve the ecological footprint of rolled roofing and contribute to long-term cost savings.
