How To Install Rolled Roofing On A Patio

Are you looking for an affordable and efficient way to protect your patio from the elements? Rolled roofing might be the solution you need.

This type of roofing material is easy to install, even if you have little experience in roofing projects. With a few tools and some basic knowledge, you can transform your patio into a safe and comfortable outdoor space that lasts for years.

In this article, we’ll guide you through the process of installing rolled roofing on your patio. We’ll cover everything from measuring and preparing the surface to cutting and installing the underlayment, laying down the rolled roofing itself, sealing the edges and seams, and adding finishing touches.

By following these steps carefully, you’ll be able to create a waterproof barrier that protects your patio from rain, snow, wind, and sunlight – all while ensuring that it looks great and functions as intended. So let’s get started!

Measure and Prepare Your Patio

Before you start laying down your new waterproof surface, take the time to properly measure and prepare your outdoor space for maximum durability and longevity.

Start by choosing a durable underlayment that will provide a solid base for your rolled roofing. You can choose from various options such as synthetic materials or traditional felt paper.

Next, properly level the patio surface to ensure that water does not pool on top of it, which could lead to damage over time. Any dips or low spots should be filled in with concrete patching compound or self-leveling cement.

Additionally, check the slope of the patio; it should have at least 2% slope away from any adjacent structures to ensure proper drainage.

Once you have chosen an appropriate underlayment and leveled the patio surface, you’re ready to cut and install it according to the manufacturer’s instructions. This step is critical for ensuring a smooth installation process and optimal performance of your rolled roofing system.

By taking these steps before installing rolled roofing on your patio, you’ll help increase its lifespan while also reducing future maintenance needs.

Cut and Install the Underlayment

Now it’s time to lay down the foundation for your new outdoor space by cutting and securing the protective layer underneath. This is where overlap techniques come into play, ensuring that no water seeps through your patio’s surface.

Begin by using necessary tools such as a utility knife or scissors to cut the underlayment into appropriate sizes according to the dimensions of your patio. It’s essential to leave at least six inches of extra material on each side of the underlayment, allowing you to overlap them securely.

Starting from one end, lay down the first piece of underlayment on top of your patio’s surface and secure it with roofing nails or staples every two feet along its edges. Ensure that you avoid creating any wrinkles in the material, which can lead to unwanted bumps in your final rolled roofing installation.

Remember always to be mindful of safety when working with sharp tools and equipment such as ladders while installing underlayment onto your patio.

Once you’ve finished laying down all pieces, use a broom or roller brush to smooth out any bumps or bubbles that may have formed during installation before moving onto rolling out your roofing sheets in our next step.

Install the Rolled Roofing

Get ready to transform your outdoor space with the next step – it’s time to lay down the finishing touches and protect your new area from any potential damage that may occur. Installing rolled roofing on a patio isn’t complicated, but it does require some effort and attention to detail.

To ensure that everything goes smoothly, make sure you’ve got all the necessary tools required such as roofing nails, a hammer, utility knife, chalk line, tin snips, and a measuring tape.

Here are some common mistakes to avoid when installing rolled roofing:

  • Don’t start in the middle of the roof. Always start at one end and work your way across.
  • Avoid cutting corners when it comes to underlayment. Make sure you’ve installed enough layers before moving onto the actual rolled roofing.
  • Don’t rush through this process. Take your time measuring each section and applying each layer carefully.
  • Don’t forget about safety! Wear sturdy shoes with good grip and use caution when walking on steeply pitched roofs.

Now that you have everything you need and know what mistakes to avoid, it’s time to install the rolled roofing. Begin by unrolling a section of roofing material along one side of the roof. Then use roofing nails (spaced about 6 inches apart) to secure it into place along both sides of the material strip.

Repeat this process until every inch of your patio is covered with rolled roofing.

As you finish up laying down your rolled roofing, remember that sealing all edges and seams is essential in ensuring water-tightness for years ahead without worrying about leaks or damage caused by rainwater seepage underneath vulnerable areas where gaps may exist between strips or around corners, etcetera.

Seal the Edges and Seams

Protect your hard work and investment by making sure every nook and cranny is sealed tight, preventing any potential water damage from ruining your outdoor oasis.

Start by applying adhesive to the edges of the rolled roofing, pressing down firmly to secure it in place. Make sure to overlap each row of roofing at least 2 inches to ensure complete coverage.

Once all the rows are in place, it’s time to seal the edges and seams with a high-quality sealant that can withstand harsh weather conditions. Choosing the right sealant is crucial for ensuring a long-lasting finish that won’t crack or peel over time.

Look for a product specifically designed for rolled roofing and apply it generously along all the edges and seams, using a caulk gun or trowel.

With the edges and seams properly sealed, you’re ready to move on to finishing touches like adding trim pieces or painting the roofing surface. But before you do, take one last look around your patio and make sure everything is perfectly aligned and secure.

With proper installation techniques and attention to detail, your rolled roofing should provide years of protection against even the toughest outdoor elements.

Finishing Touches

Trim the excess roofing material around the edges of your patio to give it a neat and tidy appearance. Use a sharp utility knife to carefully cut along the edges, taking care not to damage the underlying structure.

If your patio is prone to water damage, consider adding flashing and gutters to prevent water from seeping in and causing further damage.

Trim the Excess Roofing Material

Now it’s time to tidy up the edges of your new roof and make sure everything is looking sharp. Trim any excess roofing material that overhangs the edge of your patio. Use a utility knife to cut along the edge, making sure to use a straight edge or another tool as a guide for a clean, even cut.

If there are any gaps between the roofing material and the wall or other structures around your patio, you can fill them with alternative materials like caulk or sealant. This will help prevent water from seeping in and causing damage to your newly installed roof.

Additionally, make sure to perform regular maintenance on your rolled roofing by cleaning off any debris that may accumulate on top of it. Doing so will extend its lifespan and keep it looking great for years to come.

With all that finished, you’re almost done! The final step is adding flashing and gutters if needed, which we’ll cover in the next section.

Add Flashing and Gutters if Needed

Don’t forget to add the finishing touches to your new roof by incorporating flashing and gutters if necessary.

Proper drainage is crucial for any roofing project, especially on patios where water can accumulate easily. Gutters will direct the flow of water away from your patio and prevent any potential damage caused by standing water.

When it comes to flashing materials, there are a few options to consider. Aluminum is a popular choice because it’s lightweight and durable. Copper is another option that offers excellent corrosion resistance and can add a nice decorative touch.

Whichever material you choose, make sure it’s properly installed to ensure maximum protection against leaks and water damage.

Adding these finishing touches will not only improve the functionality of your patio roof but also increase its lifespan, giving you peace of mind for years to come.


Congratulations, you’ve successfully installed rolled roofing on your patio!

With the right materials and tools, this project can be completed in a day or two. Remember to take accurate measurements and properly prepare your patio before beginning installation.

Cutting and installing the underlayment is crucial for ensuring a strong base for the rolled roofing. When it comes to actually installing the rolled roofing, make sure to follow manufacturer instructions carefully. Take your time sealing edges and seams to prevent leaks.

Finally, add any finishing touches such as trim or flashing. Now you can sit back and enjoy your newly covered patio!
