How to Felt a Shed Roof: An Essential Guide

Felt roofing is a popular choice for shed owners due to its durability, cost-effectiveness and ease of installation. Roofing felt acts as a protective barrier, shielding your shed roof from weather damage and extending its lifespan. You might consider felting your shed roof if you notice worn-out patches, leaks or simply wish to refresh the shed’s appearance.

Choosing the right felt and installing it correctly ensures your shed remains weatherproof and structurally sound. Roofing felt is available in several types, such as traditional bitumen, polyester-based and self-adhesive options, each providing varying levels of protection and ease of use.

Tools and Materials You’ll Need to Felt a Shed Roof

Equipping yourself with the right tools and materials is key to a successful roofing felt installation. Here are some of the items you’ll need:

  • Roofing felt: Available in various types including traditional bitumen, polyester-based, and self-adhesive options.

  • Measuring tape: For accurate calculations of the felt size required.

  • Hammer: Needed if you're securing the felt with nails.

  • Utility knife: Essential for precise cutting of the felt.

  • Adhesives: Useful if you're opting for a nail-free installation; they provide a strong, lasting bond.

  • Brush or roller: Helps apply adhesive evenly for a smoother, more consistent finish.

  • Safety gear: Don’t forget gloves and goggles to protect yourself during installation.

Preparing Your Shed Roof for Felting

Properly preparing your shed roof is an important step before installing roofing felt, as it ensures a smooth application and extends the life of your roofing materials.

1. Clean the roof surface: Remove all debris, dirt and any remnants of old materials to ensure proper adhesion.

2. Inspect for damage: Check for loose boards, protruding nails, or structural weaknesses and make necessary repairs before moving on.

3. Measure the roof accurately: Use a measuring tape to determine the exact amount of felt needed, factoring in extra for overlaps.

4. Account for overlaps: Always allow additional felt for overlapping edges to ensure effective water protection.

Don't forget: A clean and dry roof surface is crucial for successful felt installation. Accurate measurements help ensure full coverage without gaps.

How to Install Roofing Felt on a Shed

Installing roofing felt on a shed is a straightforward process. However, if you’d prefer to leave it to the building professionals, hiring a roofer is the best way to help ensure a durable and weather-tight finish.

1. Measure your shed roof: Ensure you have enough roofing felt, allowing extra for necessary overlaps.

2. Cut the felt to size: Unroll and trim the felt, making sure it extends slightly beyond the edges of the roof for added weatherproofing.

3. Lay the first strip of felt: Start at the eaves (bottom edge) and work upwards, overlapping each new layer by at least 5 cm to prevent water ingress.

4. Secure the felt: Use either nails or adhesive. For nails, start from the centre and work outward to remove air bubbles. Use galvanised nails to prevent rust. For adhesive, apply an even coat and press the felt down firmly.

5. Fold and secure the edges: Tuck the felt over the roof edges and fasten it securely underneath the fascia or roofline.

6. Inspect the finished roof: Check that all felt is properly attached and overlaps are sealed to ensure full coverage and protection.

7. Maintain regularly: Inspect your shed roof every few months to catch and address any issues early, helping to extend its lifespan and weather resistance.

Techniques for Laying Felt on Different Types of Shed Roofs

Different types of shed roofs require varied approaches when it comes to laying roofing felt. The techniques you use can significantly affect the durability and weatherproofing of your shed. Choosing the right method helps ensure that your shed remains protected from environmental elements, extending the roof's lifespan.

How to Felt a Pent Shed Roof

A pent shed roof, characterised by its single slope, poses unique challenges when felting.

To start, measure your roofing felt to fit the sloped structure accurately. The angle requires precise cutting to prevent water pooling at the low edge. Begin by laying the felt from the lowest point, working your way up, ensuring overlaps are secure to maintain effective drainage.

Use an adhesive to hold the felt in place, especially on the peak where wind exposure is higher. Add an extra layer of felt at the lowest edge for improved water resistance.

How to Felt a Shed Roof Without Nails

If you prefer not to use nails, there are effective adhesive options for securing felt. Opt for a high-quality roofing adhesive designed to withstand various weather conditions. Begin by ensuring that the roof is clean, dry and free of any debris or old felt.

Apply the adhesive evenly across the roof's surface, carefully pressing the felt into place for a firm hold. Special attention should be given to corners and edges to avoid lifting. The adhesive method not only provides a neat finish but also reduces the potential for leaks. Allow sufficient drying time for the adhesive to set properly, usually around 24 hours.

How to Re-Felt a Shed Roof: Renewal and Maintenance

How to felt shed roof 3

Over time, even felted shed roofs require renewal due to wear and tear. Re-felting a shed roof is a cost-effective way to extend its lifespan, protecting your valuable belongings from the elements.

1. Inspect the existing roof felt: Look for signs of damage such as leaks, cracks, or visible wear.

2. Remove the old felt: Carefully strip away the existing felt and dispose of it responsibly.

3. Check the roof structure: While the old felt is removed, inspect for rotting wood, loose boards or structural damage. Make necessary repairs before proceeding.

4. Measure the roof: Accurately measure the surface area, allowing extra for overlaps to ensure full coverage and water resistance.

5. Cut the new felt: Trim the felt according to your measurements, ensuring it extends slightly beyond the roof edges for better protection.

6. Apply the new felt: Begin at the eaves and work upwards, overlapping each layer by at least 5 cm to prevent water ingress.

7. Secure the felt: Choose your method. If using nails, select galvanised nails for durability and rust resistance. For adhesive, apply evenly to ensure a clean, nail-free finish.

8. Final check: Ensure all layers are secure and overlaps are tight for maximum protection.

Note: Before or after re-felting, a thorough roof clean can help extend its longevity. Moss, algae and built-up debris can compromise waterproofing. Check out our roof cleaning cost guide for more information.

Roofing a shed with felt can present several challenges, including wrinkling, tear resistance, adhesion issues and moisture protection. To overcome these:

  1. Wrinkling: Ensure the felt is laid out on a flat surface for a few hours before application to relax it. Carefully unroll and lay the felt to avoid creases.

  2. Tear Resistance: Use a high-quality, durable felt and handle it gently during installation to prevent tears. Consider using reinforced felt for added strength.

  3. Adhesion Issues: Apply adhesive or nails securely at regular intervals. Make sure surfaces are clean and dry before application to prevent lifting.

  4. Moisture Protection: Use a waterproof adhesive under the felt and overlap the edges generously to ensure water runoff, preventing leakage and ingress.

Outhouse shed roofs

Anonymous user 25/06/2026 - 7.56 AM

Hi I have a 1940’s old terrace house, put the back are 2 old coal and toilet sheds. They have reinforced concrete roofs, there are steps up and was previously covered in decking. They started to leak so I removed decking and looks like old torch on felt underneath that’s disintegrated. I want to continue to use this area and maybe lay some artificial grass on top what would be the best option. I’ve had recommendations for a grp roof, some say 11mm osb on top and some say 18mm osb to stop movement and cracking the grp. Considering it will be fixed to a solid concrete base will 11mm suffice?

Hi everyone and thank you for reading this. I have a terraced Victorian house which needs a roof replacement. Company A: - inspected roof and loft space, sent me videos to comment; noticed water ingress in the loft - offered to keep existing tiles to keep price down - new membranes, battens, eaves support trays, repair of current chimney lead work, dry ridge, bonding gutters -25years guarantee -25% deposit, rest when works are complete Company B: - much quicker visit, did not go up the loft but went all the way up to the chimney via outside, took photos for own reference - offered new tiles and all of the above plus uPVC soffit and fascia, new lead flashing around the chimney and new concrete ridge tiles, new cement flaunching to the chimney and repoint - 20 years guarantee - 25% deposit, 25% half way through, rest when works are finished They both quoted the same price and both companies have glowing reviews. Which one would I be better off using? Or none of the two sounds ok to you? Thank you so much. South East.
