What Roll Roofing Is Used For: Applications, Benefits, and Considerations
Roll roofing is a versatile and cost-effective roofing material widely used in residential and commercial construction. It offers a simple installation process and serves as a practical solution for certain types of roofing projects. Understanding what roll roofing is used for can help property owners and builders select the right roofing option for their specific needs.
| Feature | Description |
|---|---|
| Primary Uses | Low-slope roofs, sheds, garages, and temporary roofing |
| Benefits | Cost-effective, easy to install, good moisture protection |
| Material Types | Asphalt-saturated felt, modified bitumen, fiber base |
| Typical Lifespan | 5 to 10 years, depending on quality and environment |
| Installation | Rolls are rolled out and fastened with nails or adhesive |
Overview of Roll Roofing
Roll roofing consists of long sheets of roofing material that come in rolls, usually 36 inches wide and 33 feet long. It typically features a base of felt or fiberglass reinforced with asphalt and coated with granules for weather resistance. This roofing is popular for its affordability and fast installation compared to traditional shingles or tile.
Common Uses of Roll Roofing
Low-Slope and Flat Roofs
Roll roofing is most commonly used on low-slope or flat roofs where traditional shingles are not ideal. It provides sufficient waterproofing and protects simple roof structures like patios, carports, and small residential extensions.
Sheds and Outbuildings
Due to its ease of installation and cost-efficiency, roll roofing is frequently applied to smaller structures like storage sheds, workshops, and garages, especially when a durable, weather-resistant roof is needed quickly.
Temporary or Emergency Roofing
In scenarios requiring quick sheltering or patching damaged roofs, roll roofing serves as a temporary solution, shielding from rain and moisture until permanent repairs or replacements are performed.
Underlayment for Other Roofing Systems
Sometimes roll roofing is used as an underlayment beneath metal roofing or tile roofs, offering an additional moisture barrier layer.
Advantages of Roll Roofing
- Cost-Effective: Roll roofing is significantly cheaper than other roofing materials, making it ideal for budget-conscious projects.
- Easy Installation: Its lightweight and flexible nature allows for quick installation without specialized tools or contractors.
- Water-Resistant: Asphalt overlays and granules provide good protection from rain, reducing leaks on suitably pitched roofs.
- Low Maintenance: Requires minimal upkeep compared to complex roofing systems if installed correctly.
- Lightweight: Does not add substantial weight to structures, suitable for older buildings with limited load capacity.
Material Types and Quality Variations
There are several types of roll roofing materials, each suited for different needs:
| Material Type | Characteristics | Typical Applications |
|---|---|---|
| Asphalt-Saturated Felt | Traditional, inexpensive, good moisture resistance but less durable | Temporary or low-budget low-slope roofs |
| Modified Bitumen | Reinforced with polymers for greater flexibility and durability | More permanent roofing projects requiring UV and weather resistance |
| Fiberglass Base Roll | Stronger base material, better fire resistance | Commercial roofing and flat roofs with higher lifespan expectations |
Limitations and Considerations
While roll roofing is practical, it has some limitations that influence its suitability:
- Lifespan: Generally shorter (5-10 years) than traditional shingles or metal roofs.
- Appearance: Less aesthetically pleasing, often unsuitable for high-end homes or architectural designs.
- Slope Requirements: Best used on roofs with minimal slope – steep roofs require other materials.
- Durability: Can be prone to cracking, tearing, or drying out in extreme weather conditions.
Installation Process for Roll Roofing
The installation involves:
- Cleaning and preparing the roof surface.
- Rolling out the roofing material across the roof area.
- Smoothing out wrinkles and securing edges with roofing nails or adhesive.
- Applying overlapping seams for water-tightness.
- Adding finishing materials like cap strips or sealants as needed.
Proper installation is crucial for maximizing roll roofing lifespan and performance. Inadequate fastening or poor surface preparation leads to leaks and damage.
When to Choose Roll Roofing Over Other Options
Roll roofing makes sense when:
- Budget constraints are tight but roofing protection is needed.
- Coverage is needed on secondary or less visible structures.
- Quick installation for temporary or emergency roofing solutions.
- Roof shape and slope suit roll roofing design.
For residential homes with aesthetic or longevity priorities, traditional shingles, metal roofing, or tiles may be preferable. However, roll roofing remains a valuable choice for many practical applications due to its affordability and ease of use.
