Mastering the proper techniques ensures your roofing felt won’t lift or let moisture in over time. Even if you’re new to DIY roofing, following clear steps and using the right materials will help you achieve a professional look without frustration.
In this guide on how to fold felt roof corners, we’ll walk you through every part of the process. You’ll also find a detailed list of the tools and materials you need, common questions answered, and expert tips so that your project stands the test of time.
Why is Proper Roofing Felt Installation Important?
Proper roofing felt installation is crucial to ensuring the longevity and durability of your roof. Roofing felt acts as a protective barrier between the roof deck and the elements, preventing water penetration that could lead to rot, mold, or structural damage. It provides an added layer of defense against extreme weather conditions, such as heavy rain, wind, or snow, reducing the risk of leaks.
Additionally, well-installed roofing felt helps insulate your home by improving energy efficiency and can extend the lifespan of the shingles or final roof covering. Without proper installation, the roof may be more prone to premature wear and costly repairs, making this step an essential part of any roofing project.

8 Simple Step-By-Step Guidelines on How to Fold Felt Roof Corners
Step 1: Prepare the Surface
Before starting, thoroughly clean the roof surface by removing all dust, debris, and previous roofing material. This is crucial, as a clean base ensures the new felt will adhere properly and last longer. Check for any nails, splinters, or sectional damage that may affect the installation.
Once the area is clean, dry, and smooth, use the measuring tape to gauge the needs of each corner. Having proper measurements will prevent mistakes once you begin cutting and folding the felt. It’s also recommended to wear gloves and goggles for safety.
Step 2: Measure and Cut the Felt
Carefully measure the length and width of the roof’s main sections and corners. Mark the felt with chalk or a pencil, adding a few extra inches to each measurement to allow for overlap and proper coverage.
Using a utility knife or sharp scissors, cut the felt according to your markings. Double-check your cuts to ensure accuracy, as crooked or short pieces may leave gaps or create weak points in the protection against water.
Step 3: Attach the Main Felt Sections
Lay the main felt sections onto the roof, starting from the bottom edge and working upwards to ensure proper water runoff. Apply adhesive or secure the felt with roofing nails every 6-8 inches along the edges to prevent wind uplift.
Smooth the felt out as you go, pressing out air bubbles or wrinkles so the material lies flat. Proper adhesion now will provide a sturdy base as you move on to folding the corners.
Step 4: Mark and Cut Corner Sections
At each corner, mark the felt where it will need to fold over the edges. Use your chalk to draw clean, straight lines that will serve as guides for your cuts. Make sure your cuts are straight and don’t overcut, since excess cutting can cause leaks later.
Once marked, make careful cuts from the edge toward the roof, stopping just before the corner itself. This will allow the felt to bend neatly around the edges without bunching or tearing.
Step 5: Begin Folding the First Corner
Raise the felt flap created by your cut and gently fold it over the edge of the roof. Work slowly to ease out any wrinkles or bubbles, and ensure the felt sits flush with both the horizontal and vertical surfaces of the corner.
Use your hand or a flat tool to press firmly along all folds. Secure the flap in place temporarily with a nail or a dab of adhesive until all adjustments are complete, then fix it permanently.
Step 6: Align and Overlap the Second Flap
Bring the adjacent felt section over the first flap at the corner, creating an overlapping seam. The overlap should be at least 2–3 inches for maximum protection from weather and water ingress.
Press the overlapping layers firmly together, using adhesive or nails as needed to hold them in place. Carefully smooth down the area to remove any air pockets, which could weaken the seal if left.
Step 7: Secure the Corners with Nails or Adhesive
Go over all folded and overlapped areas to check for gaps or loose edges. Apply felt adhesive generously beneath any loose sections, then press down again to bond the materials together. If using nails, space them a few inches apart along the seams.
It’s important to pay attention to the very tip of the corner where multiple layers meet. Use additional adhesive or a small patch of felt if necessary to reinforce this area and stop water from seeping in.
Step 8: Inspect and Finish the Job
Once all the corners are folded and secured, do a final inspection. Look for loose edges, exposed nails, or gaps where water could enter. Add extra adhesive or nail in additional spots as needed for peace of mind.
Allow all adhesives to dry or cure according to the manufacturer’s instructions before exposing the roof to weather. This ensures maximum durability and performance from your finished felt corners.
Following these steps on how to fold felt roof corners properly can help ensure a secure and watertight roof. It may take some extra time and effort, but proper corner folding is essential for the overall integrity of your roof.
Additional Tips
Work in Ideal Weather Conditions
Avoid working on your roof during extreme weather conditions, such as heavy rain or strong winds. Dry and calm weather ensures better adhesion and reduces the risk of accidents.
Use Quality Materials
Invest in high-quality roofing felt and adhesive to ensure the best possible outcome. Cheaper materials may compromise the durability and longevity of your roof.
Always Measure Twice
Double-check your measurements before making any cuts. This helps minimize material waste and ensures a precise fit for your felt roofing.
Wear Safety Gear
Always wear appropriate safety equipment, including non-slip shoes and a harness if working at height, to reduce the risk of injury.
Inspect Regularly
Periodically inspect your roof for signs of wear, damage, or potential leaks, and address them promptly to prevent long-term issues.
Frequently Asked Questions
Q1: What Is the Best Tool for Cutting Roofing Felt?
A sharp utility knife is generally considered the best tool for cutting roofing felt cleanly and safely. It allows you to make precise adjustments to the felt’s size and shape. Always use a straightedge or a ruler for extra accuracy when marking and cutting, as jagged edges can weaken the fold or let in moisture. Wearing protective gloves is also recommended to avoid cuts.
Q2: How Can I Make Sure My Felt Corners Are Watertight?
Thorough adhesion and strategic overlapping are key to watertight corners. Be sure to apply adhesive under every fold, especially where pieces overlap, and press each layer down firmly. Pay special attention to the very tip of each corner, as this is the most vulnerable spot for leaks. Checking your work closely and using extra patches if needed will enhance long-term weather resistance.
Q3: Should I Use Nails or Adhesive for Roof Felt?
Both nails and adhesives are commonly used, but your choice depends on roof type and personal preference. Adhesive creates a nearly seamless bond and is especially effective against wind and rain. Nails work well for quick securing, particularly around edges where wind uplift is a concern. Combining both often yields the best results, leveraging each method’s strengths.
Q4: Can I Fold Felt Roof Corners Alone or Should I Get Help?
While it’s possible to fold felt corners on your own, having another person to help can make the process much easier and safer. An extra set of hands is especially handy for holding the felt taut and making sure overlaps are exact. Solo work requires more patience and care, but can still be done successfully with proper tools and preparation. Teamwork, though, usually means smoother installation and fewer mistakes.
Conclusion
Folding felt roof corners might seem challenging at first, but with the right preparation, detailed steps, and reliable materials, the process becomes manageable for any DIY enthusiast. Taking your time with each fold and overlap ensures that your roof will be secure and watertight for years to come.
