How to Install Roll Roofing?
Roll roofing might not sound glamorous, but it’s a practical, budget-friendly solution for many roofing projects. Whether you’re a DIY enthusiast or a homeowner looking to save on roof repairs, roll roofing could be the answer. In this guide, we’ll walk you through everything you need to know about installing roll roofing, from preparation to the final touches.
What is Roll Roofing?
Roll roofing is a mineral-surfaced roofing material that’s sold in rolls. It’s typically used for low-slope roofs and is a popular choice for sheds, garages, and other outbuildings. Unlike traditional shingles, roll roofing is applied in long strips, making installation quick and straightforward.
Benefits of Roll Roofing
- Cost-effective: Roll roofing is one of the most affordable roofing options available.
- Easy to install: Its simplicity makes it a great choice for DIY projects.
- Quick application: You can cover a large area in a short amount of time.
- Versatile: Suitable for various types of buildings and structures.
Types of Roll Roofing
Asphalt Roll Roofing
This is the most common type of roll roofing, made from the same materials as asphalt shingles but in a rolled form. It’s durable and offers good protection against the elements.
Mineral Surface Roll Roofing
This type features a mineral granule surface that provides additional weather resistance and a bit of aesthetic appeal. It’s a step up from basic asphalt roll roofing.
Smooth Finish Roll Roofing
Smooth finish roll roofing is often used as a base layer or for temporary installations. It’s not as durable as the mineral surface variety but can be useful in certain situations.

Preparing for Installation
Safety Precautions
Before you start, ensure you have the necessary safety gear, such as gloves, safety glasses, and non-slip shoes. Working on a roof can be dangerous, so it’s crucial to take appropriate precautions.
Inspecting and Cleaning the Roof
Inspect your roof for any damage or debris. Clean the surface thoroughly to ensure proper adhesion of the roll roofing. Repair any holes or damaged areas before proceeding.
Measuring and Cutting Roll Roofing
Taking Accurate Measurements
Measure the length and width of your roof to determine how much roll roofing you’ll need. Add a bit extra to account for overlaps and trimming.
Cutting Techniques
Use a utility knife to cut the roll roofing to the required lengths. Cutting on a flat, stable surface will help you achieve straight, clean edges.
Installing the Roofing Underlayment
Importance of Underlayment
Underlayment adds an extra layer of protection against moisture and helps extend the life of your roofing. It’s especially important for low-slope roofs where water drainage might be slower.
Step-by-Step Installation
- Roll out the underlayment: Start at the lowest point of the roof and work your way up.
- Secure with nails or staples: Fasten the underlayment every 6-8 inches along the edges and seams.
- Overlap edges: Make sure to overlap each strip of underlayment by at least 4 inches to ensure complete coverage.
Laying Out the Roll Roofing
Starting Point
Begin at the lowest edge of the roof, usually the eaves. This will help ensure proper water runoff and prevent leaks.
Aligning the Rolls
Use a chalk line to mark straight lines on the roof. This will guide your placement and help keep the rolls aligned properly.
Nailing Down Roll Roofing
Proper Nailing Technique
Nail the roll roofing in place, starting from the center and working your way out to the edges. This helps eliminate wrinkles and bubbles.
Nail Spacing and Placement
Place nails about 6-8 inches apart along the edges and seams. Ensure the nails are flush with the surface but not so tight that they cut into the material.
Sealing the Edges and Overlaps
Importance of Sealing
Sealing is crucial to prevent water from seeping under the roofing material. Proper sealing ensures a longer lifespan and better performance of your roof.
Materials Used for Sealing
Use roofing cement or adhesive to seal the edges and overlaps. Apply a generous amount and spread it evenly with a trowel or brush.
Finishing Touches
Trimming Excess Material
Once all the rolls are in place, trim any excess material along the edges. This gives your roof a neat, finished look.
Inspecting the Final Installation
Check the entire roof for any missed spots, loose nails, or areas that need additional sealing. A thorough inspection ensures a job well done.
Common Mistakes to Avoid
Avoiding Wrinkles and Bubbles
Ensure the roll roofing is laid flat and smooth. Wrinkles and bubbles can lead to leaks and reduce the lifespan of your roof.
Ensuring Proper Drainage
Make sure the roofing slopes correctly to allow for proper water drainage. Poor drainage can cause water pooling and damage over time.
Maintenance Tips for Roll Roofing
Regular Inspections
Inspect your roof regularly, especially after severe weather. Look for signs of damage or wear and address them promptly.
Repairing Minor Damages
Use roofing cement to repair minor cracks or holes. Timely repairs can prevent more significant issues down the line.
Cost Considerations
Material Costs
Roll roofing is one of the most affordable roofing materials. Costs can vary depending on the type and quality you choose.
Labor Costs
If you’re hiring a professional, labor costs can add to your budget. However, the simplicity of roll roofing often makes it a cost-effective choice even with labor included.
Environmental Impact
Eco-Friendly Options
Some roll roofing materials are made from recycled materials, making them an eco-friendly choice.
Recycling Old Roofing Materials
When replacing your roof, consider recycling the old materials. Many recycling centers accept roofing materials, reducing landfill waste.
