How to felt a sloping roof
If you have a sloping roof that needs to be felted, you’ve come to the right place. Felting a sloping roof may seem like a daunting task, but with the right tools and techniques, you can do it yourself.
First, it’s essential to gather all the necessary tools and materials for the project. You’ll need roofing felt, nails, a hammer, a utility knife, and a ladder. It’s also a good idea to have someone assist you, especially when working on a sloping roof.
Once you have everything you need, start by cleaning the roof thoroughly. Remove any debris, moss, or loose shingles to ensure a clean surface. Next, measure the length and width of the roof to determine how much felt you’ll need. It’s always a good idea to buy extra, just in case.
Now it’s time to lay the roofing felt. Start at the bottom of the roof and secure the felt with nails, spacing them every few inches. Make sure to overlap each row of felt by a few inches to ensure proper water drainage. Keep working your way up the roof, securing the felt as you go.
Step-by-step guide to felting a sloping roof
Felting a sloping roof is a task that requires careful planning and precision. This step-by-step guide will take you through the process to ensure a successful roofing project.
Materials needed:
- Felt roll
- Roofing nails
- Hammer
- Roofing adhesive
- Roofing cement
- Utility knife
- Tape measure
- Chalk line
- Ladder
- Safety goggles

- Dust mask
Before you start:
Ensure that the roof is dry, clean, and free from any debris. It is advised to work on a warm and dry day for better adhesion.
Step 1: Measure and cut the felt
Start by measuring the length of the roof and cut the first piece of felt according to the measurement. Leave a few inches of extra felt on both sides for an overlap.
Step 2: Secure the first piece of felt
Begin at the bottom edge of the roof and secure the first piece of felt using roofing adhesive or nails with a small amount of roofing cement. Smooth out any wrinkles or bubbles as you go along.
Step 3: Add additional layers
Overlap the second piece of felt over the first, ensuring an even coverage. Secure it in place using roofing adhesive or nails with roofing cement. Repeat this process for all the necessary layers, overlapping them appropriately to ensure water drainage.
Step 4: Trim and finish
Once all the pieces of felt are secured, trim any excess felt using a utility knife. Apply roofing cement along the edges to provide added protection against wind and water. Check for any areas that may need extra sealing or patching.
Step 5: Inspect and maintain
Finally, carefully inspect the roof for any loose or lifted felt. Make necessary repairs and maintain the roof regularly to extend its lifespan.

Preparing the Roof
Before you begin the process of felting a sloping roof, it is important to properly prepare the roof to ensure a successful and long-lasting result.
Here are the steps to follow while preparing the roof for felting:
| Clean the Surface | Start by removing any debris, dirt, or loose materials from the roof surface. Use a brush or a broom to sweep away the debris, and a power washer can be used to remove any stubborn dirt or moss. Ensure that the surface is completely clean and free of any loose materials. |
| Repair Any Damage | Inspect the roof for any signs of damage, such as cracked or missing tiles, loose flashing, or damaged fascia boards. Repair or replace any damaged areas before proceeding with the felting process to ensure that the roof is in good condition. |
| Install Roof Ventilation | If your roof does not already have proper ventilation, consider installing roof vents to improve airflow and prevent condensation. Adequate ventilation is crucial for the overall health of the roof and can help to prevent issues such as rot and mold. |
| Apply a Roof Primer | Before felting, it is recommended to apply a roof primer to ensure better adhesion of the felt material. This will help to create a strong bond between the felt and the underlay, increasing the longevity of the roof’s waterproofing. |
| Create a Falls | Since you are dealing with a sloping roof, it is essential to create a proper falls or a slight slope to allow for proper water runoff. This can be achieved by using timber battens or furring strips as a base for the roof felt, allowing the water to flow toward the gutters. |
By thoroughly preparing the roof before felting, you can ensure that the process goes smoothly and that the result is a weatherproof and long-lasting roof covering.
Installing the underlay
Before applying the underlay, it is important to ensure that the sloping roof is clean and free from debris. Remove any loose nails or old roofing materials from the surface.
The underlay acts as a waterproof barrier and provides added insulation to the roof. It is typically made of bitumen or synthetic materials. Start by unrolling the underlay on one end of the roof and secure it in place with staples or roofing nails. Overlap each row by approximately 6 inches to ensure complete coverage.
When installing the underlay, make sure to maintain a slight slope towards the edges of the roof to allow for proper drainage. This helps to prevent water from pooling on the roof and causing damage. Use a level to ensure that the underlay is installed evenly and that there are no low spots where water can accumulate.
Step 1: Cut the felt
Measure the length of the roof and cut the underlay to the appropriate size using a utility knife. Make sure to leave an extra few inches on each end for overlapping purposes.
Step 2: Install the underlay
|
1. Start at one end of the roof and roll out the underlay, keeping it straight and aligned with the edge of the roof. |
4. Secure the underlay with staples or roofing nails approximately 6 inches apart, making sure to flatten any wrinkles or bubbles as you go along. |
|
2. Use a hammer or staple gun to secure the underlay in place, ensuring it is tight and wrinkle-free. Alternatively, you can use adhesive or a hot air torch to bond the underlay to the roof if applicable. |
5. Repeat the process for each additional row, overlapping the edges of the underlay by approximately 6 inches. |
|
3. Continue unrolling the underlay and securing it in place, working your way towards the opposite end of the roof. |
By following these steps and taking proper precautions, you can ensure that the underlay is properly installed on your sloping roof. This will provide a solid foundation for the rest of the roofing materials and help enhance the integrity and longevity of your roof.
Fitting the felt shingles
Once the roof has been prepared and the underlayment has been installed, it’s time to start fitting the felt shingles. Felt shingles are a popular choice for sloping roofs due to their durability and water-resistant properties. Here’s a step-by-step guide on how to fit felt shingles for a sloping roof:
1. Prepare the area
Before you start fitting the felt shingles, make sure the surface is clean and free from any debris. Remove any loose nails or debris from the previous roof covering to ensure a smooth and even surface.
2. Measure and mark the roof
Start by measuring the width of the roof and divide it by the width of the felt shingles to determine the number of rows you’ll need. Use a chalk line or a pencil to mark where each row of shingles will go. It’s important to ensure that the first row is aligned properly before starting to lay the shingles.
3. Start laying the shingles
Begin by positioning the first row of shingles along the bottom edge of the roof, aligning them with the marked lines. Use roofing nails to secure each shingle in place, making sure to leave a small gap between each shingle for expansion. Smooth out any wrinkles or bubbles in the felt shingles as you go along.
Continue fastening the shingles row by row, working your way towards the top of the roof. Make sure each row overlaps the previous row by at least 2 inches to ensure proper water drainage. Trim any excess shingles at the edges if necessary.
4. Finishing touches
Once all the shingles are in place, go back and inspect your work. Check for any loose or improperly secured shingles and fix them accordingly. Use a roofing sealant to secure the ridge line and any exposed nail heads. This will provide extra protection against water infiltration and strengthen the overall integrity of the roof.
Remember to consult the manufacturer’s instructions and guidelines for any specific details or requirements for the felt shingles you are using. With proper installation and regular maintenance, your felt shingle roof can provide many years of reliable protection against the elements.
Please note that the above instructions are general guidelines and may not be applicable to all roof types or specific situations. It is recommended to consult a professional roofer or follow the manufacturer’s instructions for your particular project.
