When your roof is damaged or nearing the end of its lifespan, deciding how to repair or replace it can feel overwhelming. For many homeowners, the two biggest concerns are budget and speed. If you need a quick, affordable, and simple solution, you might have heard about roll roofing.

Although roll roofing has been used for decades, it’s less common than traditional asphalt shingles due to its specific applications and limitations. Using it on the wrong roof or pitch can lead to early leaks and costly repairs. But when applied appropriately, roll roofing can save you both time and money.

This blog will explain what roll roofing is, how it’s installed, when it’s the right choice, and what you can expect from it over time. You’ll also learn when it’s a practical short-term fix and when you might want to consider other roofing options.

What Exactly Is Roll Roofing?

Roll roofing, also called mineral-surfaced roll roofing (MSR), is a roofing material that comes in large sheets instead of individual shingles. Rolls are typically 36 inches wide and cover about 100 square feet each. The top layer features mineral granules to protect against the weather, while the base is a fiberglass mat impregnated with asphalt.

Although it looks similar to asphalt shingles, roll roofing is lighter and less durable. That’s why it’s commonly used for:

• Detached garages

• Sheds and workshops

• Barns and storage buildings

• Low-slope roofs

It’s generally not recommended for main residential roofs due to its shorter lifespan and limited aesthetic appeal.

How Is Roll Roofing Installed?

One of roll roofing’s biggest advantages is how easy it is to install. Unlike shingles, which are installed piece by piece, roll roofing is laid down in large, continuous strips. The typical installation process involves:

1. Preparing the Roof Surface: Cleaning and repairing the roof deck for a smooth base.

2. Adding Underlayment: Sometimes a roofing felt layer is applied to help prevent moisture.

3. Measuring and Cutting: Cutting the rolls to fit each section of the roof.

4. Laying the Rolls: Unrolling the material horizontally from the bottom up.

5. Securing the Roofing: Using nails or adhesive to fix it in place.

6. Sealing Seams: Applying tar or adhesive to overlapped seams to keep water out.

Because each roll covers a large area, installation is quick and can often be done by DIY enthusiasts, though professional installation ensures better durability and fewer leaks.

When Should You Choose Roll Roofing?

Roll roofing is best suited for certain situations:

• Low-Slope Roofs: Works well on roofs with gentle slopes (around 1:12).

• Temporary Repairs: Provides a quick fix until a full roof replacement is possible.

• Outbuildings: Ideal for sheds, barns, and other structures where looks are less important.

• Tight Budgets: A cost-effective option when upfront savings matter most.

It’s not ideal for steep roofs or homes where appearance and longevity are priorities.

What About the Cost?

Affordability is a key reason homeowners choose roll roofing:

• Materials: Typically cost less than half as much as asphalt shingles per square foot.

• Labor: Installation costs are lower and can be eliminated if you do it yourself.

• Short-Term Savings: Great for saving money now, but may require more frequent replacements.

In mild climates, roll roofing lasts about 5 to 8 years, but in hot, humid places like Florida, it may only last 3 to 5 years, potentially increasing your long-term expenses.

Performance in Humid Climates

In regions with intense sun, heat, and moisture, roll roofing faces challenges like:

• UV Damage: Sunlight can dry out and crack the material.

• Expansion and Contraction: Temperature changes cause the material to expand and contract, leading to splits.

• Water Exposure: High humidity and rain make proper sealing crucial to prevent leaks.

For these reasons, roll roofing in humid climates should be considered a temporary or emergency solution, not a permanent one.

How to Maintain Roll Roofing

To maximize the lifespan of your roll roofing, regular upkeep is essential:

• Inspect Twice a Year: Look for cracks, blisters, or loose seams, especially after storms.

• Remove Debris: Clear leaves and branches that can trap moisture.

• Reseal Seams: Apply roofing cement if edges start to lift.

• Limit Foot Traffic: Avoid walking on roll roofing to prevent damage.

• Address Small Repairs Quickly: Fix minor tears before they worsen.

Why Professional Roof Inspections Matter

Even with its simple installation, having a professional inspect your roof before adding roll roofing is wise. Inspectors can:

• Confirm your roof’s slope and structure are suitable.

• Detect any hidden water damage.

• Recommend the best installation method for your climate.

• Estimate the expected lifespan of the roll roofing on your roof.

This is especially important in areas prone to storms or extreme weather, where poor installation can cause costly problems.

Final Thoughts

Roll roofing can be a smart, budget-friendly option for certain cases, like outbuildings, low-slope roofs, or temporary repairs. However, it’s not the best choice for a permanent roof on your home, especially if you want something durable and visually appealing.

Consider both the short-term savings and potential long-term costs, and get a professional inspection to ensure your roofing investment is sound.
