Professional Shed Re-Felting in Brentwood
Replacing worn or damaged shed felt is a regular maintenance job for property owners throughout Brentwood and the wider Essex area. Even correctly installed shed felt will wear out over time, particularly on roofs exposed to trees, strong sunlight or severe weather.
Once the felt splits or pulls away from the edges, rainwater can soak into the roof boards beneath. Early re-felting is usually less expensive than waiting until both the covering and boards require replacement.
We help customers in Brentwood request quotations for shed re-felting, boarding repairs and complete roof replacement. Complete one online enquiry and you may receive contact from up to four contractors serving Brentwood and nearby areas of Essex.
When Should Shed Felt Be Replaced in Brentwood?
Many homeowners only notice a problem once damp patches or drips appear inside the building.
Your shed roof may need re-felting if you notice:
- Visible damage across one or more roof sections.
- The covering pulling away from fascia boards and edge battens.
- Blisters, bubbles or raised areas.
- Gaps appearing where sheets of felt overlap.
- A covering that continues to leak despite previous work.
- Water marks or dark stains inside the shed.
- Roof decking that has started to rot.
- The protective finish becoming thin or patchy.
- Moss, leaves or debris collecting on the roof.
- Torn sections following bad weather.
What Shortens the Life of Shed Felt?
Several factors can shorten the lifespan of shed roofing felt.
- General wear and tear — the waterproof surface weakens as the material reaches the end of its useful life.
- UV and sunlight damage — repeated heating and cooling can make felt expand, contract and crack.
- Freezing and thawing — moisture in small cracks can freeze and widen them.
- Felt pulling away from the perimeter — poorly fixed edges can curl and loosen over time.
- Failed lap joints — incorrectly formed joints may open as the roof moves.
- Loss of adhesion — air or moisture below the covering can form raised areas that eventually split.
- Wind uplift — once one edge comes loose, damage can spread across the roof.
- Falling branches and debris — debris from nearby trees may damage the surface.
- Lack of maintenance — moss holds moisture against the roof and may grow into joints.
- Incorrect fitting — using the wrong product for the roof pitch can lead to leaks.
Types of Shed Roofing Felt Available in Brentwood
The right product will depend on the shed design, roof pitch and how exposed the property is.
Traditional Mineral Felt
Standard mineral felt is the most affordable and widely used option for garden sheds. The material should be installed over a dry, sound deck and secured carefully around the roof edges.
Upgraded Shed Roofing Felt
Heavy-duty felt is thicker and generally more resistant to splitting, UV exposure and temperature changes. Better-quality felt can provide stronger seams and improved resistance to wind uplift.
Cold-Applied Felt Systems
Self-adhesive felt provides a flame-free method of covering a timber shed roof. Careful positioning is needed to avoid trapped air, creases and poorly sealed laps.
Built-Up Felt Systems
Some larger sheds, garages and workshops may be suitable for torch-on felt installed by an experienced contractor. Timber sheds are not always suitable for flame application, so a cold-applied alternative may be recommended.
Layered Felt Installation
Some roofers install an underlay beneath the mineral cap sheet to create a more substantial waterproof system. The contractor should explain the products, fixing method and expected performance.
What Local Shed Roofers Can Do
Removing the Existing Felt
- Stripping brittle, torn or patched material.
- Preparing the boards for the replacement felt.
- Checking for hidden damp and rot.
- Cleaning the roof surface before installation.
- Leaving the site clear after completion.
Roof Board and Timber Replacement
The timber deck may appear sound from outside but become soft or rotten after years of water ingress.
- Renewing damaged sheet material beneath the felt.
- Replacing tongue-and-groove timber boards.
- Strengthening weakened roof timbers.
- Rebuilding low sections where water collects.
- Replacing rotten fascia boards and edge battens.
- Adjusting the deck to encourage drainage.
Installing a New Shed Roof Covering
A full re-cover involves replacing the felt across every roof section rather than patching isolated areas.
The contractor should use suitable lap widths, adhesive and fixings for the chosen product.
Localised Shed Re-Felting
Partial replacement may be possible when only one side or section has failed. The age and condition of the surrounding covering will affect whether this approach is worthwhile.
Securing New Shed Felt
- Finishing the felt neatly around the eaves and verges.
- Creating a clean drip edge.
- Renewing rotten battens before finishing the felt.
- Forming a watertight apex ridge.
- Finishing junctions with suitable adhesive and fixings.
- Preventing rainwater from tracking behind fascias.
Storm-Damaged Shed Felt Replacement
- Stripping material that has blown back.
- Reducing further water ingress after bad weather.
- Replacing boards damaged by falling branches.
- Replacing finishing components lost in high winds.
- Confirming that the structure remains stable.
Upgrading from Traditional Shed Felt
Traditional felt is not the only option for sheds and outbuildings.
Rubber Membrane Shed Roofs
EPDM is a flexible rubber membrane commonly used on flat and low-pitched shed roofs. The membrane is bonded to a smooth, dry deck and completed with purpose-made edge trims.
Replacing Felt with Corrugated Sheets
Corrugated bitumen sheets may suit pitched sheds, workshops and storage buildings. The roof frame may require additional support before installation.
Replacing Felt with Metal Panels
Metal roofing is commonly used on larger sheds, garages and workshops. Anti-condensation backing may be available for buildings affected by moisture.
Hard-Finish Flat Roofing
GRP forms a hard and seamless waterproof surface over a suitable timber deck. The roof deck must be stable and correctly prepared.
Shed Felt Replacement for Different Roofs
The service can be used for more than a basic wooden garden shed.
- Traditional double-slope sheds.
- Lean-to-style shed roofs.
- Flat-roofed storage sheds.
- Hobby rooms and work sheds.
- Timber garden rooms.
- Garden offices.
- Small outdoor storage units.
- Outdoor animal buildings.
- Detached garages and workshops.
- Utility buildings with flat roofs.

Frequently Asked Questions
How often does shed roof felt need replacing in Brentwood?
How long the covering lasts varies according to the product used and the conditions around the shed. A strong felt system may remain serviceable for ten to fifteen years or more in favourable conditions. Strong sunlight, trees, moss and wind exposure can shorten this lifespan.
Can new shed felt be installed over old felt?
Some roofers may over-felt a sound covering, although doing so can hide damage underneath. A clean and stable deck generally provides a more reliable base.
Can rotten roof boards be replaced during re-felting?
Yes, contractors can normally replace rotten plywood, OSB or timber boards as part of the job. The roofer should inspect the structure after stripping the old covering.
Which type of felt is best for a shed roof?
A simple garden shed may not require the same specification as a workshop or garden office. Standard mineral felt is affordable, while heavy-duty and self-adhesive products can offer improved performance.
Can I replace shed roof felt myself in Brentwood?
DIY replacement may be manageable where the roof is easy to reach and the boards are sound. Professional installation may provide a neater and longer-lasting result.
How long does shed roof felt replacement take?
A small straightforward shed may be completed within a few hours. Rain and strong winds may delay installation.
Can shed roof felt be replaced in wet weather?
Temporary weatherproofing may sometimes be possible, but final installation often needs dry conditions. Strong winds can also make handling large rolls of felt unsafe.
Should I choose EPDM instead of felt for my shed in Brentwood?
Rubber roofing normally costs more initially but can reduce the need for repeated replacement. A local contractor can compare the likely costs and benefits.
How much does shed roof felt replacement cost in Brentwood?
The price depends on the size and shape of the roof, the felt grade and whether the timber deck needs repair. Photographs and measurements may help roofers prepare an initial estimate.
