What Is Roll Roofing Used For: Applications and Benefits in Residential and Commercial Roofing
Roll roofing is a versatile and cost-effective roofing material commonly used in both residential and commercial construction. It is designed for easy installation, durability, and weather resistance, making it a popular choice for specific roofing needs. This article explores the primary uses of roll roofing, its advantages, and why it remains a practical option for many property owners.
| Application | Description | Common Use |
|---|---|---|
| Low-Slope Roofs | Ideal for roofs with gentle slopes where traditional shingles may not perform well | Residential and commercial buildings |
| Secondary Roofing | Used as an underlayer beneath other roofing materials for added waterproofing | Various building types |
| Sheds and Outbuildings | Provides a simple, weather-resistant roofing solution for smaller structures | Garages, sheds, and temporary buildings |
| Temporary Roofing | Offers a quick and cost-effective roofing option during construction or repairs | Construction sites and emergency repairs |
Overview of Roll Roofing
Roll roofing is a type of roofing material sold in long rolls, typically 3 feet wide and up to 33 feet long. It is made from asphalt-saturated organic felt or fiberglass mats coated with mineral granules. This design allows for easy transportation and installation, especially on low-pitched roofs where conventional shingles may be impractical. Roll roofing is favored because it balances affordability with functional weather protection.
Primary Uses of Roll Roofing
Low-Slope and Flat Roofs
Roll roofing is most commonly used on low-slope or flat roofs where traditional asphalt shingles might not shed water effectively. Because roll roofing comes in continuous sheets, it provides a nearly seamless surface, reducing the risk of water infiltration on roofs with less than 3:12 pitch.
Sheds, Garages, and Outbuildings
For smaller structures like sheds, garages, and other outbuildings, roll roofing offers a straightforward installation process. Its affordability and weather resistance make it an attractive roofing system for these types of buildings, where aesthetic considerations are often less critical.
Underlayment for Roofing Systems
In many instances, roll roofing acts as a secondary roofing material or underlayment beneath tile, metal, or other roofing types. It adds an extra waterproofing layer to protect the building’s structure, especially in areas prone to heavy rainfall or snow accumulation.
Temporary and Emergency Roofing Solutions
Roll roofing serves as a reliable temporary roofing option during construction or emergency repairs. The ease of installation allows property owners or contractors to quickly seal damaged areas and protect the interior from weather exposure while planning permanent repairs.
Advantages of Using Roll Roofing
- Cost-Effectiveness: Roll roofing is considerably cheaper than most traditional roofing materials, which benefits homeowners and businesses with budget constraints.
- Ease of Installation: Its roll format allows for quicker installation, often reducing labor costs and project timelines.
- Lightweight: The material puts less structural stress on buildings, ideal for older or less robust structures.
- Water Resistance: When properly installed, roll roofing provides effective protection against rain, snow, and wind.
- Maintenance Simplicity: Repairs are easy with patching materials readily available, supporting long-term cost savings.
Limitations and Considerations When Choosing Roll Roofing
While roll roofing has many benefits, it’s important to consider its limitations. It is generally less durable than high-end roofing materials like metal, slate, or architectural shingles. The typical lifespan ranges from 5 to 10 years, which is relatively short for permanent roofing solutions.
Additionally, roll roofing is usually not recommended for roofs with steep slopes or those requiring high aesthetic value. Its appearance is often considered less visually appealing, which may impact curb appeal for residential properties.
Ideal Roofing Scenarios for Roll Roofing
| Scenario | Reason | Example |
|---|---|---|
| Budget Constraints | Provides affordable roofing without sacrificing waterproofing | Low-income housing, rental properties |
| Supplemental Waterproofing | Functions effectively as a secondary layer | Under tile or metal roofs in wet climates |
| Quick Fix or Temporary Roof | Easy installation for fast coverage | Post-storm repairs or construction phase |
| Low-Traffic Roofs | Less frequent maintenance and use | Sheds, storage units, or greenhouses |
Roll Roofing Installation Basics
Installation of roll roofing is straightforward but requires attention to detail for optimum results. The roof surface must be clean, dry, and smooth before application. The material is rolled out horizontally, overlapped, and secured with roofing nails or adhesive. Mineral granule surfaces should face up to protect against UV rays and weather.
Proper sealing of seams and edges is essential to prevent water infiltration. Many roofers recommend additional waterproof underlayment or flashing to improve durability, especially in climates subject to extreme weather conditions.
Maintenance Tips for Roll Roofing
- Regular Inspections: Check for tears, blisters, or loose sections especially after storms or heavy winds.
- Prompt Repairs: Address small issues immediately using patch kits to avoid water damage.
- Keep Surface Clear: Remove debris that can retain moisture or cause damage.
- Re-Seal Edges: Apply roofing cement or sealant at exposed edges annually for added protection.
Summary
Roll roofing serves as a practical, economical option for low-slope roofs, sheds, temporary structures, and as a secondary roofing layer. It balances simplicity, water resistance, and cost-effectiveness, making it ideal for many building types where long-term durability and aesthetics are secondary concerns. While it requires regular maintenance and has a limited lifespan compared to premium roofing materials, its ease of installation and affordability continue to make it a favorable choice.
