Roll on roof shingles provide a lightweight, affordable solution for protecting flat or low-slope roofs. This guide explains what roll-on shingles are, how they are installed, and when they are the right choice for a project. It covers materials, durability, maintenance, and cost to help homeowners decide if rolled roofing is suitable for their home’s needs.
What Are Roll On Roof Shingles?
Roll on roof shingles, also known as rolled roofing, are narrow sheets of asphalt-saturated material that come in rolls. They are designed for low-slope or flat roofs and provide a simple, cost-effective barrier against the elements. Unlike traditional asphalt shingles, roll-on shingles are installed in continuous lengths, with seam overlaps sealed by asphalt or adhesive tapes.
Materials And Options
Roll on roof shingles come in several varieties, with asphalt being the most common. Other options include modified bitumen and synthetic roll roofing, which may offer improved durability and UV resistance. Key considerations when choosing material include:
- Thickness and weight: Heavier rolls tend to resist wind uplift better but can be harder to handle.
- Adhesive or seam method: Some products rely on self-sealing asphalt, while others require additional seam tapes or hot asphalt.
- UV resistance: Higher UV stability extends service life in sunny climates.
- Flexibility in temperature: Cold-weather installation may require products formulated for low temperatures.
Installation Guide For Roll On Roof Shingles
Proper installation is essential for rolled roofing to perform as intended. The steps below outline a typical process for a flat or low-slope roof:
- Surface preparation: Clear debris, repair any bent or damaged decking, and ensure a clean, dry substrate. Use a compatible underlayment if recommended by the manufacturer.
- Roll alignment: Measure and snap reference chalk lines along the eaves and ridge to ensure straight rows and consistent overlaps.
- Unrolling and positioning: Unroll the material starting at the lowest edge. Align edges carefully to maintain even seams along the length.
- Seaming and attachment: Install using the recommended method—adhesive, self-adhesive tape, or hot asphalt. Overlap per product specifications to create a watertight seam.
- Edge details: Seal terminations at rake edges, penetrations, and transitions with compatible flashing and sealant to prevent leaks.
- Inspection: Check for gaps, loose edges, or bubbles and address promptly before curing or weather events.
Pros And Cons
Understanding the benefits and limitations helps determine if roll on roof shingles are appropriate for a project:
- Pros: Fast installation on small roofs or repairs; cost-effective per project; lightweight; suitable for low-slope surfaces.
- Cons: Generally shorter lifespan than higher-end shingles; more prone to wind uplift in windy climates; less durable against foot traffic and heavy hail; limited color and texture options compared to traditional shingles.
Maintenance, Repairs And Longevity
Roll on roof shingles require routine upkeep to maximize lifespan. Inspect after severe weather for punctures, cracks, or lifted edges. Promptly address any damage with patching materials or by replacing affected rolls. For extended longevity, perform periodic cleaning to remove organic growth and ensure gutters and downspouts are clear to prevent water backup that can seep under seams.

Cost And Where To Use
Cost is typically a key consideration for homeowners. Roll on roof shingles are among the most affordable roofing options when compared to traditional shingles or metal roofing. Costs vary based on material, climate, roof size, and labor. In general, rolled roofing is well suited for:
- Flat or low-slope residential roofs such as sheds, porches, and garages
- Budget-conscious renovations where a temporary or interim solution is acceptable
- Outbuildings or accessory structures where aesthetics are less critical than function
For homes with significant slope, high wind exposure, or long-term durability concerns, homeowners may prefer more robust systems such as architectural asphalt shingles or metal roofing. A professional assessment can help determine whether roll on roof shingles meet performance expectations for local weather patterns.
Comparison At A Glance
| Aspect | Roll On Roof Shingles | Traditional Asphalt Shingles |
|---|---|---|
| Best Uses | Flat or low-slope roofs, budget projects | Steep-sloped roofs, long-term durability |
| Installation Speed | Very fast for small areas | Moderate |
| Durability | Good for the price, shorter lifespan | High, long lifespan with proper maintenance |
| Wind Resistance | Lower in high-wind areas | Higher when installed correctly |
| Appearance Options | Limited | Variety of colors and textures |
Practical Tips For Consumers
To maximize effectiveness and value from roll on roof shingles, consider the following:
- Climate considerations: In areas with heavy rainfall and strong winds, assess wind uplift ratings and product warranties.
- Professional installation: While DIY is possible on small projects, improper sealing can lead to leaks. Hire a contractor with experience in roll roofing installation.
- Warranty and codes: Check manufacturer warranties and local building codes to ensure compliance and eligible coverage.
- Ventilation and insulation: Ensure the roof assembly is properly ventilated to minimize moisture buildup beneath rolled roofing.
Roll on roof shingles offer a practical, economical option for specific roofing scenarios, especially flat or low-slope surfaces where frame strength and weight limits are critical. By understanding materials, installation methods, and appropriate applications, homeowners can choose a solution that balances cost, speed, and performance.
