Roll Roofing
Introduction to Roll Roofing
What Is Roll Roofing?
Roll roofing, often referred to as rolled roofing, is one of the simplest and most cost-effective roofing materials available today. It’s a mineral-surfaced roofing product that comes in rolls—hence the name—and is designed primarily for low-slope or flat roofs. Made from the same materials as asphalt shingles, roll roofing is composed of an organic or fiberglass mat that’s saturated with asphalt and topped with mineral granules. This makes it water-resistant and suitable for outdoor exposure.
One roll typically covers about 100 square feet and comes in widths of 36 inches. It’s easy to transport, simple to store, and can be applied quickly, even by DIY enthusiasts with basic tools. That’s why it’s become a go-to option for sheds, garages, porches, and low-slope roofs that don’t require the same aesthetic appeal or longevity as other roofing types.
So why is roll roofing still so popular in an age dominated by architectural shingles and high-end materials like metal and slate? It’s all about simplicity and affordability. When you need a quick fix or a temporary roof that doesn’t break the bank, roll roofing steps up to the plate.
History and Evolution of Roll Roofing
Roll roofing has been around since the late 19th century, evolving alongside the development of asphalt shingles. In the early days, roofing materials were expensive and labor-intensive, so manufacturers developed roll roofing as a low-cost, mass-produced alternative.
Originally, these products were less durable and mainly used in emergency repairs. Over time, with improvements in asphalt technology and the introduction of reinforced mats, roll roofing has become a more reliable option. Today’s versions include rubberized and polymer-modified options that greatly increase flexibility and resistance to weather extremes.
Interestingly, roll roofing’s usage hasn’t declined despite newer technologies. In fact, it's become more popular in niche applications—especially for small outbuildings, temporary roofing, and DIY-friendly projects. While it's not typically used for residential main roofs anymore, roll roofing still plays a key role in the roofing industry.
Types of Roll Roofing Materials
Asphalt Roll Roofing
Asphalt roll roofing is the most common and budget-friendly type. It's essentially a large sheet of asphalt shingles without the individual tabs. Typically made from organic felt or fiberglass that’s been saturated with asphalt, it's then coated with mineral granules to resist UV damage.
This type is easy to cut and install using roofing cement or nails. However, it's also the least durable, often lasting only 5–10 years depending on the climate and installation quality. It’s a solid choice for tool sheds, temporary shelters, or where aesthetics aren’t a major concern.
The affordability and accessibility of asphalt roll roofing make it a favorite among DIYers and budget-conscious homeowners. Still, for more demanding applications, you may want to consider upgraded types.
Mineral-Surfaced Roofing (MSR)
MSR is basically an umbrella term for asphalt-based roll roofing that’s surfaced with mineral granules. These granules provide a protective barrier against the sun’s UV rays and add a bit of durability.
You’ll find MSR in both smooth and granular varieties. The granular type is better for areas exposed to more weathering, while smooth MSR is typically used under other roofing materials or for temporary fixes. This makes it a bit more versatile than standard asphalt rolls.
MSR is also available in a few different colors—though mostly in neutral tones like gray, black, and brown. It’s not winning any style awards, but it’s functional, and sometimes that’s all you need.
Rubber and EPDM Roll Roofing
If you're looking for something a bit more advanced, rubber roll roofing might be your best bet. EPDM (ethylene propylene diene monomer) is a synthetic rubber that’s extremely durable and flexible, even in cold temperatures.
EPDM roll roofing comes in large, seamless sheets that are glued or mechanically fastened to the roof surface. It’s known for resisting leaks and standing up to harsh weather, including UV exposure, wind, and even hail.
While it’s more expensive than asphalt-based products, its long life (up to 20 years or more) can actually make it a more economical choice in the long run. Plus, its flexibility makes it perfect for roofs with multiple penetrations like vents or skylights.
Modified Bitumen Roll Roofing
Modified bitumen is like asphalt roofing with a superhero upgrade. It’s enhanced with rubber or plastic polymers to give it better elasticity and durability. These rolls often come in layers that are applied using heat (torch-down method) or adhesives, making them more water-resistant and longer-lasting.
Modified bitumen roofing can last up to 20 years and offers better protection against harsh elements. It’s particularly suitable for commercial buildings or residential flat roofs where durability and performance matter more than cost.
If you’re not afraid of a more complex installation process—or are hiring a pro—modified bitumen is a top-tier roll roofing option.
Pros and Cons of Roll Roofing
Advantages of Roll Roofing
Let’s start with the good stuff. Roll roofing is:
Affordable – It’s one of the cheapest roofing materials on the market.
Quick to Install – With minimal tools and skills, you can get a roof covered in just a few hours.
Lightweight – Easier to transport and manage, especially for small-scale projects.
Low Maintenance – While not the most durable, it requires very little upkeep.
Great for Outbuildings – Ideal for non-critical structures like sheds and barns.
For homeowners on a tight budget or with urgent roofing needs, roll roofing offers a straightforward solution without a steep learning curve. It’s also a solid short-term fix if you’re planning to upgrade your roof in the near future.
Disadvantages and Limitations
Of course, it’s not all sunshine and rainbows. Roll roofing also comes with its fair share of drawbacks:
Short Lifespan – Most products only last 5 to 10 years.
Limited Aesthetic Appeal – It's not exactly beautiful; if curb appeal matters, this isn’t your best bet.
Not Ideal for Steep Roofs – Roll roofing is mainly designed for low-slope surfaces.
Seam Issues – Over time, seams can open and allow water in if not sealed properly.
Temperature Sensitivity – Some materials can become brittle in cold weather or soft in extreme heat.
In short, roll roofing is best viewed as a practical solution, not a long-term investment—especially if you live in an area with extreme weather conditions.
When to Use Roll Roofing
Ideal Applications for Roll Roofing
Roll roofing is like the Swiss Army knife of roofing materials when it comes to specific use cases. It shines in scenarios such as:
Garden Sheds and Storage Buildings
Garages and Workshops
Porches and Covered Patios
Dog Houses and Animal Shelters
Temporary Structures or Emergency Repairs
It’s also an excellent underlayment for other types of roofing, such as metal or shingles, adding an extra layer of moisture protection. If you're planning a short-term roofing solution or have a structure that doesn’t require an architectural finish, roll roofing fits the bill perfectly.
Climate and Environmental Considerations
Roll roofing performs best in mild climates where temperature swings are minimal. In hot climates, the material can soften and become prone to blistering. In cold regions, it may crack or shrink over time if not installed correctly.
If you’re in a storm-prone area, you'll want to reinforce the edges and seams with additional adhesive or sealants. Also, keep in mind that UV exposure is a big enemy of roll roofing—especially cheaper varieties. So installing it in shaded or partially covered areas can extend its life.
Cost of Roll Roofing
Material Cost Breakdown
The cost of roll roofing varies depending on the type, brand, and thickness. Here’s a general breakdown:
Type of Roll RoofingPrice per Roll (100 sq. ft.)Asphalt Roll Roofing$30 – $50Mineral-Surfaced Roofing$40 – $60Rubber/EPDM Roofing$80 – $150Modified Bitumen Roofing$100 – $200
These are ballpark figures, but they give you a good sense of how much you might spend depending on your roofing needs.
Installation Cost and Budgeting Tips
If you’re going the DIY route, you can expect minimal costs beyond the material itself. You’ll need tools like a utility knife, roofing nails, and sealant—maybe $50–$100 for everything.
Hiring a professional? Labor will add $1–$2 per square foot, meaning your total cost could range from $200–$400 for a 100-square-foot area.
Budgeting Tips:
Buy in bulk for bigger projects.
Look for end-of-season sales at home improvement stores.
Use coupons or contractor discounts when available.
