-
The advantages and disadvantages of asphalt roll roofing
-
Practical advice, real-world usage, and when to call a professional
What Is Roll Roofing?
Roll roofing comes in long strips—typically 36 inches wide by up to 100 feet long. It’s made of asphalt-saturated felt topped with mineral granules, making asphalt roll roofing a thinner and more flexible alternative to traditional shingles. It’s especially suited for flat roof or very low-slope surfaces where other roofing types may not perform well.
Installation is straightforward: roll it out, fasten it down, and overlap the seams. Ensuring proper seam sealing and good drainage is essential to maintain leak protection.
Common Roll Roofing Types:
-
Asphalt Roll Roofing – Affordable and pliable for simple projects
-
Mineral-Surfaced Roofing – More durable with an additional protective granular layer
-
Saturated Felt Roll Roofing – Often used as an underlayment or temporary cover
-
Rubber Roll Roofing – Eco-friendly and ideal for flat rooftops
Advantages of Roll Roofing
1. Economical Solution
Cost-effectiveness is the biggest advantage. Roll roofing materials are far less expensive than shingles, metal, or tile—and labor costs are lower too, especially for DIY installations.
2. Fast Installation
You can install this roofing quickly on flat or low-slope surfaces using only basic tools. No need for specialized equipment or roofing crews.
3. Lightweight
Because it’s lighter than shingle, metal, or tile roofing, it’s ideal for older structures or buildings that can’t support heavy loads.
4. Tailored for Flat Roofs
Specifically designed for roll roofing for flat roof projects, it offers fewer seams (less leakage risk) and easier installation than shingles.
5. Perfect for Temporary or Secondary Structures
If you need a low-cost option for non-residential buildings or rental spaces, roll roofing is a practical choice.
Limitations of Roll Roofing
1. Shorter Lifespan
Typically, roll roofing lasts 5–8 years, making it less durable than shingles or metal (which can last decades).
2. Lower Durability
Its thin composition makes it vulnerable to wind uplift, hail damage, UV degradation, and punctures from foot traffic or debris.
3. Minimal Aesthetic Appeal
Limited design and color options make it more suitable for utility buildings than homes requiring visual appeal.
4. Not Suitable for Sloped Roofs
Not engineered for steeper angles—water runoff isn’t handled as well as it is on shingled roofs.
5. Greater Leak Potential
If seams are not sealed properly or water pools, roll roofing can degrade and eventually leak over time.
Is Roll Roofing Right for You?
Best Scenarios:
-
Flat or low-slope structures like sheds or utility buildings
-
Projects with tight budget or short-term needs
-
DIY installs where speed and cost control matter more than long-term durability
When to Consider Alternatives:
-
If you’re looking for long-term performance and curb appeal
-
In areas with severe weather (wind, heavy rain, hail)
-
On main living spaces where aesthetics and durability are priorities
Answers to Common Roll Roofing Questions
What’s the main difference between asphalt roll roofing and shingles?
Roll roofing is less expensive and easier to install, but it has a shorter lifespan and lacks the refined look of shingles.
Can I install roll roofing myself?
Yes—but proper drain setup and careful sealing of seams are critical to avoid leaks.
How long should I expect roll roofing to last?
Approximately 5–8 years, depending on exposure to sun and weather.
Is roll roofing waterproof on flat roofs?
It can be—if installed correctly and well-sealed. However, it’s more vulnerable than more robust systems like rubber membranes or TPO.
Installation Best Practices
-
Only use on low-slope or flat surfaces.
-
Ensure proper drainage to avoid standing water.
-
Overlap sheets by at least 2 inches and seal seams with roofing cement or tape.
-
Minimize foot traffic to prevent punctures.
-
Plan inspection or replacement around year 5–8.
Alternatives to Consider
-
Architectural Shingles – Last 15–30 years, offer better aesthetics
-
Rubber Roofing (EPDM / TPO) – Excellent waterproofing and durability for flat roofs
-
Metal Roofing – Long-lasting, low-maintenance, high upfront cost
Final Thoughts
If you’re seeking a budget-friendly, easy-to-install roofing option for a secondary or outbuilding, roll roofing, particularly asphalt roll roofing, may be ideal. It’s especially effective for flat roof applications. However, for primary residences or structures requiring long-term durability and curb appeal, better alternatives exist.
