Felting a roof shed is a great way to add a protective layer and extend its lifespan. The process involves brushing the wool fibers to matt them together, creating a dense and water-resistant surface.
The type of wool used is crucial, as it needs to be able to withstand the elements. Merino wool is a popular choice due to its high density and crimped fibers, which make it ideal for felting.
To ensure a successful felting process, it's essential to use the right tools, such as a felting needle and a sponge brush. A felting needle is designed to help break down the wool fibers and create a dense mat.
Regular maintenance is key to keeping your felting in top condition.
Get Prepared
Before you start felting your shed roof, it's essential to pick a dry day with little wind and temperatures ideally above 41°F (5°C). This will ensure the felt adheres securely to the roof.
Measure and cut your felt carefully, adding about 5 cm on each edge for the overlaps and 7.5 cm to the gable ends. A standard-size shed usually requires three pieces, but always check your specific needs.
Roll out your felt at least 30 minutes before use to flatten it. This will make the installation process much smoother. Avoid laying it out on your lawn, as this can cause the turf to turn temporarily yellow.
Gather all the necessary tools and materials, including clout nails, to secure the felt. A secure shed is a must-have for any backyard.
Instructions: Installation
Installing the shed roof felt is a straightforward process that can be completed quickly. You can finish a small shed in about an hour, and it's even easier with a helper.
First, clean and prepare the roof by removing any old felting material, nails, or dirt to create a smooth and even surface. This is crucial for a successful installation.
To ensure a watertight seal, use an underlay or base layer when installing shed roof felt. This provides an additional protective barrier between the roof surface and the felt, enhancing its waterproofing capabilities.
Cut the roofing felt into the lengths you need to cover the roof from front to back, leaving about 10cm longer than the length of the shed. This will give you enough overlap to secure the felt properly.
Here's a step-by-step guide to installing your shed roof felt:
- Clean and prepare the roof - ensure the roof surface is clean and free from debris before starting the installation.
- Use an underlay or base layer when installing shed roof felt.
- Cut the roofing felt into the lengths you need to cover the roof from front to back.
- Place the first piece at one edge and tack the front and back.
- Work your way up the panel to the apex of your shed’s roof.
- Tack the felt down, spacing the tacks about 150mm apart along the edges and across any areas where the felt overlaps.
- Fold the felt along the edges of the shed and tack them in place.
- For the apex piece, cut a slit and fold the piece under and secure it with tacks.
- Cover the edges on all sides with barge boards, using standard nails.
- Finally, cut away any excess felt with a craft knife to ensure a tight and secure fit.
Tools and Materials
Having all the necessary tools and materials ready will make the felting process smoother and more efficient. A good place to start is with the right hammer, a claw hammer being the best option as it helps remove nails from old felting.
You'll also need a step ladder or scaffold tower to access the roof safely. A level, which can double as a straight edge, is essential for ensuring the felting is properly aligned.
A craft knife, also known as a utility knife or roofing knife, will come in handy for cutting the felt. A tape measure will help you measure the roof to determine the square meters and calculate the amount of roofing felt needed.
Add about 25% to your measurement to account for any irregularities or overlaps. A chalk line is a useful tool for creating straight and level guidelines on the roof surface.
You'll need roofing tacks, specifically galvanized steel clout nails, to secure the felt in place. Barge boards should be at least the same width as the shed's eaves, with a few cm extra being acceptable.
Other essential materials include shed roof felting, underlay or base layer, felt adhesive or sealant, and safety equipment such as safety gloves, safety glasses or goggles, and a dust mask.
Here's a list of the tools and materials you'll need:
- Claw hammer
- Step ladder or scaffold tower
- Level
- Craft knife (or utility knife or roofing knife)
- Tape measure
- Chalk line
- Roofing tacks (galvanized steel clout nails)
- Barge boards
- Shed roof felting

Best Practices
To ensure a successful felting project, it's essential to follow best practices. Use a sturdy backing material, such as plywood or oriented strand board (OSB), to prevent the felt from warping or bending.
Measure the roof shed carefully to determine the exact amount of felt needed, as a little extra can go a long way. This will also help prevent waste and save you money.
When applying the felt, start at the bottom edge and work your way up, using a notched trowel to spread the adhesive evenly and prevent air bubbles from forming.
Replacing Best Practices
Replacing shed roof felt can be a straightforward task if you follow the best practices. Clean and prepare the roof to ensure an even surface.
To create a watertight seal, properly overlap and seal each layer of felt by at least 2 inches, using adhesive or sealant at the edges and overlaps. This will prevent water from seeping underneath.
Safety should always be your top priority when installing felt on a shed roof. Use proper safety gear, such as gloves and safety glasses, to protect yourself from sharp objects or adhesives.
Use a stable and secure surface for installation, and avoid doing it during adverse weather conditions to prevent accidents and injuries.
Secure the felting with appropriate roofing nails, following manufacturer guidelines. This will prevent the felt from lifting or shifting during harsh weather conditions.
Trim the edges of the felt neatly and accurately with a sharp utility knife to ensure a clean and professional finish. This reduces the risk of potential damage caused by loose or frayed edges.
Invest in high-quality shed felt and underlay or base layer to ensure better durability and weather resistance. Quality materials provide long-lasting protection for your shed.
Here's a summary of the key best practices for replacing shed roof felt:
Work in dry conditions to ensure the adhesive and felting's effectiveness are not compromised. Wet or damp surfaces can lead to costly repairs and compromised protection.
Best Options
Professional-grade roofing felt is the best option for a shed roof. It's worth investing in this type of felt, as it will last for years.
Look for felt that has been reinforced with polyester for a superior, weather-foiling finish. This type of felt will provide a long-lasting result.
Cheaper, tissue-thin varieties of felt may seem like a cost-effective option, but they won't last as long as professional-grade felt. They're not worth the risk of having to replace them sooner rather than later.
Tidy Up
Securing the corners of your shed is just the first step in achieving a neat and organized space. Reattach the fascia boards by nailing them back in place.
Excess shed felt can make your shed look cluttered, so trim it to size using your knife.
Maintenance and Replacement
Regular inspections and proactive upkeep are vital to ensure the longevity of your shed roof felt replacement. Conduct routine inspections to check for any signs of wear, tears, or damage on the felt surface.
You should check the felt roof of your shed annually for leaks or any sign of wear and tear. Replace your shed's felt as soon as you see signs of damage, to prevent leaks.
