Installing felt paper or synthetic underlayment is an important step in any roof installation process. Whether you're replacing an existing roof or building a new one, proper underlayment installation is key to ensure your roof will last for years and protect your home from water damage. This guide will walk you through the process of installing felt paper or synthetic underlayment, step-by-step, so you can do it right the first time. The first step in installing felt paper or synthetic underlayment is to prepare the surface. Make sure that the surface is clean and free of debris, and apply a primer or sealer if necessary.
Once the surface is prepped, you can begin to install the felt paper or synthetic underlayment. Depending on the type of material you are using, you may need to cut it to size. When cutting, be sure to use shears or a sharp utility knife for a clean cut. Next, you will need to secure the felt paper or synthetic underlayment to the surface.
This can be done by using nails, staples, or adhesive. Be sure to use fasteners that are appropriate for the material you are using and follow the manufacturer’s instructions for installation. Once the felt paper or synthetic underlayment is installed, it’s time to install the roofing material. Depending on the type of material you are using, you may need to use additional fasteners or adhesive to secure it in place. Again, be sure to follow the manufacturer’s instructions for installation. When installing felt paper or synthetic underlayment, it is important to take your time and pay attention to detail.
Make sure all seams are sealed properly, and inspect your work periodically to ensure that everything is in place. If any issues arise during installation, address them immediately so they don’t become bigger problems down the road. Finally, be sure to clean up any debris that may have accumulated during installation. This will help prevent any unnecessary damage and ensure that your roof installation is successful.
Materials and Tools NeededBefore beginning your installation of felt paper or synthetic underlayment, make sure you have all of the materials and tools required for the job.

Step-by-Step Installation GuidePrepare the surfaceBefore installing felt paper or synthetic underlayment, the surface should be properly prepared.
This includes removing any debris or old roofing material, leveling the surface, and applying a primer. This will ensure that the new underlayment will adhere to the surface correctly.
Cut felt paper/synthetic underlayment (if necessary)If the felt paper or synthetic underlayment does not fit the exact dimensions of the roof, it will need to be cut to size. Use a utility knife to make precise cuts along straight lines.
Secure in place using fastenersFelt paper or synthetic underlayment should be secured in place with nails or screws. Make sure to use corrosion-resistant fasteners that are designed for the material you are installing.
It is also important to ensure that the fasteners are driven in at least ¼ inch below the surface of the felt paper/synthetic underlayment.
Install roofing materialOnce the felt paper or synthetic underlayment is in place and secured, it's time to install the roofing material. Begin at the eaves of the roof and work your way up, overlapping each course as you go. Make sure to use an appropriate adhesive between each course.
Seal all seamsAfter installing the roofing material, all seams should be sealed with an appropriate sealant. This will provide an extra layer of protection against moisture damage and leaks.
Inspect work periodicallyPeriodically inspect your work for any signs of wear or damage.
If any problems are found, they should be repaired as soon as possible.
Clean up debrisAfter completing the installation, clean up any debris that may have been created during the process. This will help ensure that your roof remains in good condition for years to come. Installing felt paper or synthetic underlayment is an important part of any roof installation. With proper preparation, materials, and tools, you can successfully complete this project with confidence. By following this step-by-step guide and taking your time, you can ensure that your roof installation is strong and long-lasting.
Whether you are installing a new roof or replacing an existing one, you can rely on felt paper or synthetic underlayment to provide your roof with the protection it needs for many years to come.
