If you’re looking for an affordable, easy-to-install roofing material, rolled roofing might just be your answer. Whether you’re a DIY enthusiast trying to finish a shed or a contractor looking for an efficient solution for a low-slope roof, rolled roofing is a practical choice worth exploring.
This blog will guide you through everything you need to know about rolled roofing, from its benefits and options to step-by-step installation tips. By the end of this article, you’ll not only understand its benefits but feel confident tackling your own rolled roofing installation project.
What is Rolled Roofing?
Rolled roofing is a mineral-surfaced, asphalt-based roofing material sold in long rolls. It’s an efficient alternative to traditional shingles, particularly for low-slope roofs or small projects. Typically, rolls are about 36 inches wide and 33 feet long, which translates to 100 square feet of coverage per roll. This makes it super convenient for quick installations.
You’ll often find rolled roofing used on sheds, garages, or porch roofs—notable for areas that don’t require a fancy architectural finish but do need durable protection from the elements.
Rolled Roofing vs. Traditional Shingles
Here’s a quick rundown on the differences between rolled roofing and traditional shingles:
- Cost: Rolled roofing is typically cheaper, making it an attractive choice for cost-conscious homeowners.
- Installation: Unlike shingles, which require precise layering, rolled roofing can often be installed in just a few hours. This is perfect for DIY roofing projects.
- Durability: While a shingle roof may last 25–30 years, rolled roofing has a shorter lifespan of roughly 5–10 years, depending on the material and maintenance.
The Benefits of Rolled Roofing
1. Cost-Effectiveness
If you’re on a budget, rolled roofing is one of the most affordable roofing materials you can buy. Not only are the materials inexpensive, but installation costs are minimal, particularly if you’re doing it yourself.
2. Ease of Installation
Want to try your hand at DIY roofing? Rolled roofing is an excellent material for beginners, given its simple installation process. With basic tools, some guidance, and a bit of patience, homeowners with a knack for DIY can complete a project in just one day.
3. Versatility
While rolled roofing isn’t suitable for steeply pitched roofs, it works wonders on low-slope residential roofs and outbuildings. For small spaces like patios, sheds, or barns, it’s a practical and convenient option.
Types of Rolled Roofing
Before purchasing, you’ll need to decide which type of rolled roofing best suits your project.
1. Saturated Felt Roofing
This basic asphalt-soaked material is mostly used as underlayment but can also serve as rolled roofing for temporary, low-budget installations.
2. Modified Bitumen Roofing
A durable alternative, modified bitumen roofing includes polymer additives to improve flexibility and resistance. It’s ideal for areas exposed to extreme weather conditions.
3. Rubber Rolled Roofing
Made of EPDM rubber, this type comes in wide rolls offering great coverage with excellent waterproofing. It’s a common choice for sheds and flat roofs.
4. Mineral-Surfaced Roofing
This is the most popular type of rolled roofing, often used for DIY projects. It’s thin, lightweight, and has a mineral coating that helps it withstand rain and UV exposure.
A Step-by-Step Guide to Rolled Roofing Installation
Now that you’re familiar with the basics, here’s how to install rolled roofing like a pro.
Step 1: Gather Your Tools and Materials
Before you start, make sure you have everything you’ll need for the project:
- Rolled roofing material
- Roofing nails or adhesive
- Utility knife
- Measuring tape
- Roofing underlayment (optional for added protection)
- Ladder and safety harness
Step 2: Prepare the Roof Surface
Begin by cleaning the roof surface thoroughly. Remove any dirt, debris, or old roofing materials. A flat and clean surface is crucial to ensure the rolled roofing adheres properly.
If your roof is on the lower end of the slope spectrum, consider laying down roofing underlayment first for added waterproofing.
Step 3: Measure and Cut the Roofing Material
Measure your roof area carefully to cut the rolled roofing to the necessary length. Remember to leave a 1-inch overhang on the edges and be precise to avoid wastage or misalignment.
Step 4: Install the Roll
If you’re using adhesive:
- Apply a layer of roofing cement to the prepared roof surface.
- Roll out the roofing material over this layer, pressing it in place as you move along to secure adhesion.
If you’re using nails:
- Lay the roofing material flat and tack it into place with roofing nails, leaving a few inches between each nail.
- Overlap the next layer by about 4–6 inches to ensure waterproofing, repeating this process until your roof is fully covered.
Step 5: Seal the Edges
Seal all the edges and overlaps with roofing cement to keep water from seeping underneath. Pay particular attention to seams and corners.
Step 6: Inspect Your Work
Make sure the rolls are properly aligned with no gaps or loose nails. Secure any loose edges, and ensure the surface is smooth.
Common Mistakes to Avoid with DIY Roofing
Even with a material as simple as rolled roofing, there are potential pitfalls. Here’s how to avoid them:
- Skipping the Surface Prep: A dirty or uneven roof can lead to peeling and leaks.
- Incorrect Overlaps: Remember that overlaps of less than 4 inches can compromise waterproofing integrity.
- Ignoring Safety Gear: Always use proper safety equipment, especially when working on higher roofs.
How Long Does Rolled Roofing Last?
While rolled roofing is affordable and straightforward to install, it generally has a shorter lifespan than shingles. With proper maintenance, you can expect it to last around 5–10 years. Be sure to perform regular inspections and fix any minor issues before they turn into costly repairs.
Is Rolled Roofing the Right Choice for You?
Rolled roofing is perfect for certain projects, thanks to its low cost and straightforward installation process. It’s especially ideal for small spaces like sheds, garages, or low-slope roofs. However, it may not be the best long-term solution for homeowners seeking maximum durability and aesthetic appeal.
